* app/curves.c
* app/levels.c
Fix for gimp bug #33403. The curves and levels dialogs should now
work in GRAYA images.
2000-11-29 Austin Donnelly <austin@gimp.org>
* app/curves.c: Applied patch from David Hodson
<hodsond@ozemail.com.au> to fix Bug#33399: GIMP crashes when
applying curve to Grayscaled image when preview is off.
Previously the curves tool attempted a reset when changing
image, but didn't correctly do this. Now it has the
(more useful) behaviour of doing a partial reset, where the
curve remains the same across multiple invocations, allowing
you to apply the same tweak to multiple images. The internal
state relevant to image type/depth is correctly reset,
stopping the segfault behaviour seen before.
Still no fix for Bug#33403: Curves/Levels Tool does not work
on GRAYA-Images.
* app/image_render.c:
* app/tile.h: Removed the JIT calculation of the tile_shift
value and replaced it by a constant called TILE_SHIFT in tile.h.
This gives the compiler a better chance to optimize the code.
Also added a few consts all over the place to give the compiler
some hints.

These files should have been commited in my 2000-05-08 commit
but somehow they didnt make it.
* app/hue_saturation.c
* app/levels.c
* app/posterize.c
* app/threshold.c: Add a call to image_map_clear in the
preview toggle button callback. This makes the preview toggle
button behave as expected.
* app/histogram_tool: remove an unnecessary include.

Cursor patch II:
This is only the logic inside the cursor system and not yet used.
* app/cursorutil.[ch]: [gimp]_change_win_cursor() take lots of
parameters now and compose cursors from up to three cursor
bitmaps/masks.
* app/gdisplay.[ch]: As a test, create a hardcoded example cursor
if "Cursor Mode" is set to "Tool Icon with Crosshair" in prefs.
* app/curves.c
* app/dialog_handler.c
* app/scroll.c: changed the calls to the win_cursor function.
* app/tools.[ch]: added a cursor and a toggle cursor to the ToolInfo
structure of all tools.
* app/toolsF.h: new ToolType TOOL_TYPE_NONE.
* app/gimpdnd.c
* app/interface.c: check for silly filenames in the file dnd
callback. Closes#13733.

* cursors/zoom_small_mask.xbm: new files extracted from Tigert's
gimp-tool-cursors.xcf created at GimpCon.
Tigert, I'll commit the xcf as soon as I've added empty layers
with the names of the cursors that are missing.
* cursors/mouse.xbm
* cursors/mouse_mask.xbm: made it 32x32 to allow for cursor
composition.
2000-06-07 Sven Neumann <sven@gimp.org>
* app/pixel_region.c: applied patch provided by Daniel Egger:
store the result of tile_bpp() into a variable and use it
instead of calling it over and over again in the inner loop.
* app/pixel_region.h
* app/pixel_regionP.h:
Did some additional indentation and code cleanup.
* app/image_map.[ch]: new function image_map_clear that removes
the preview without freeing the image_map.
* app/brightness_contrast.c
* app/color_balance.c
* app/curves.c
* app/hue_saturation.c
* app/levels.c
* app/posterize.c
* app/threshold.c: Add a call to image_map_clear in the
preview toggle button callback. This makes the preview toggle
button behave as expected.
* app/histogram_tool: remove an unnecessary include.
* gimprc.in
* gimprc.win32
* app/gimprc.c: set default image size back to 256x256, default
to local paint options and info-window-follows-mouse.
* app/brightness_contrast.c
* app/docindex.c
* app/hue_saturation.c: picky changes on some labels.
* app/tips_dialog.c: applied (sort of) gimp-quinet-20000504-0,
which replaces the message "Show tip next time" in the
Tip Of The Day dialog with "Show tip next time GIMP starts".
--Sven
2000-05-05 Jay Cox <jaycox@earthlink.net>
* app/pixel_processor.c: try to minimize the overhead of
multiprocessor support. This should fix bug #9296
but it has not been tested on a dual processor machine.
2000-04-26 Michael Natterer <mitch@gimp.org>
* app/color_select.c
* app/colormaps.[ch]
* app/context_manager.c: removed unused global variables
[foreground|background]_pixel and [old|new]_color_pixel.
Initialize the colormap and visual stuff with GdkRGB instead of
GtkPreview functions (which are deprecated).
* app/[62 files]: removed #include's (started with colormaps.h and
couldn't stop). Also ordered them consistently and did some small
unrelated cleanups.
Removed variuos <stdlib.h> et.al. but checked the files carefully
before doing so. If I was too radical and you get warnings on your
platform, please flame me or just put them back :)
2000-02-13 Michael Natterer <mitch@gimp.org>
* po/POTFILES.in
* app/Makefile.am
* app/buildmenu.[ch]: removed.
* app/blend.c
* app/brush_select.c
* app/curves.c
* app/histogram_tool.c
* app/layers_dialog.c
* app/lc_dialog.c
* app/levels.c
* app/paint_options.h
* app/paintbrush.c
* app/tool_options.c: use the libgimp option menu
constructor. Removed paint_mode_menu_set_history().
* app/colormap_dialog.i.c
* app/colormap_dialog.p.h: use a popup menu as in the palette
dialog instead of a pulldown menu.
* app/channels_dialog.c: made color dnd to a channel widget work
again.
* libgimp/gimpwidgets.[ch]: new function
gimp_option_menu_set_history() which sets the history according to
user_data as passed to gimp_option_menu_new().
2000-01-25 Michael Natterer <mitch@gimp.org>
* app/appenv.h: removed BOUNDS, MINIMUM and MAXIMUM. No need to
include both <glib.h> and <gtk/gtk.h>.
* app/*
* tools/pdbgen/pdb/text_tool.pdb: s/BOUNDS/CLAMP/,
same for MIN and MAX.
* app/preferences_dialog.c: the "Check Size" widget was connected
to the transparency_type variable.
* plug-ins/common/sobel.c: removed definitions of MIN and ROUND.
* libgimp/gimp.h: #include "gimplimits.h" and "gimpcolorspace.h".
* plug-ins/*: don't include the two files.
* app/gdisplay.c
* app/gimage_cmds.c
* tools/pdbgen/pdb/gimage.pdb: fixed typos
* app/gimphistogram.c: indentation
* app/histogramwidget.c: grab the pointer in the histogramwidget,
so a button_release outside the widget is noticed correctly
* app/levels.c: instead of undoing the user action, simply don't
allow the user to set the range in the histogram_widget
--Sven
Thu Jan 6 18:39:05 GMT 2000 Adam D. Moss <adam@gimp.org>
* app/tile_cache.c
* app/tile_swap.c: Maybe fixed tile_cache_set_size()
so that it actually works now. You can use this to set GIMP's
tile cache size at runtime without restarting. If the prefs
guys (Sven, Michael?) don't wire it in I'll look at it, but it
can't be soon.
* libgimp/gimpcolorspace.c
* libgimp/gimpcolorspace.h: Prefixed all functions with gimp_
to avoid namespace collisions.
Changed the License in the header to LGPL. If you don't like this,
please remove those files! (But I would like them to stay since this
moving those functions into libgimp is something that should have
happened much earlier.) Nice work, Daniel!
* app/tile.c
* app/tile.h
* app/tile_manager.c
* app/tile_swap.c:
Allocate Tile's array of TileRowHints dynamically. Make type
of TileRowHint explicit since it's fairly space-critical.
Can save several hundred K of memory with this and struct
changes.
Added warnings for old basically-untested-or-insane
paths through the tile referencing code.
* app/tile_pvt.h: Shrink down and rearrange fields of Tile
struct to save some space with gcc's padding for most people.
* app/paint_funcs.c: Use tile_sanitize_rowhints() to ensure
that rowhints have been allocated before use.
* app/channel_ops.c
* app/gdisplay.c
* app/pixel_region.c: Cosmetic, sanity or unfinished debug
changes (the latter commented out) for fun and reference.
1999-12-07 Michael Natterer <mitch@gimp.org>
* app/main.c
* app/menus.c: Wrapped the 'plugin_domains' definition and
initialization and menu_translate() with '#ifdef ENABLE_NLS'.
* app/palette.c: Removed another trailing comma from an enum.
* app/tile_cache.c (tile_idle_thread): Changed tile->swap to
tile->swap_offset because tile->swap doesn't exist. Note that I
don't understand at all what's going on there. I commited this
because (1) this way it compiles and (2) it at least _looks_ like
the right thing to do. Garry, could you check this please?
1999-12-05 Garry R. Osgood <gosgood@idt.net>
Inaugural checkin: Tile accounting
* app/tile_cache.c
* app/tile.c
cur_cache_dirty in tile_cache.c was not being fully updated. Fewer
dirty bytes were being added to this global than what were being
placed on the dirty tile queue. Deductions, however, were correct
sometimes causing cur_cache_dirty to wrap around zero and become
large positive. This skewed the number of tiles to be swapped to disk,
usually downward, but sometimes dramatically upward.
active_tile_count, (tile.c) currently a diagnostic counter, was
not being decremented.

1999-12-02 Michael Natterer <mitch@gimp.org>
* app/app_procs.c: Default to "Cancel" in the "Really Quit?" dialog.
* app/app_procs.c
* app/brush_select.c
* app/gimpbrushlist.c: Call brush_select_[freeze|thaw]_all() from
brushes_init() and brushes_free(), so refreshing the brushes from
plugins/scripts is faster.
* app/brightness_contrast.c
* app/color_balance.c
* app/curves.c
* app/file_new_dialog.c
* app/hue_saturation.c
* app/levels.c
* app/posterize.c
* app/threshold.c:
Reorder the action are buttons: [ "OK" "Reset" "Cancel" ]
* app/menus.c: Some more cleanups in the menu code. Reorder
<Image>/Filters/Misc only if ot exists. Generalized
menu_translate() in preparation for correctly supporting catalogs
which only exist sometimes (like gimp-perl).
* app/gradient.c
* app/gradient_select.c: Save some lines of code by using
gtk_clist_new_with_titles() instead of gtk_clist_new().
* libgimp/gimpunitmenu.c: Code cleanup and made the clist titles
of the unit selection un-clickable.

* app/threshold.[ch]: spinbuttons and cleaned up ui for all
dialog-tools. Added a "Reset" button to all dialogs.
* app/color_notebook.c: fixed a compiler warning.
* app/gimpui.[ch]: made gimp_radio_group_new() more general.
* app/menus.c: removed the <Toolbox>/File/Help submenu.

(force the emission of the "tool_changed" signal)

* app/dodgeburn.c
* app/paint_options.h
* app/paintbrush.c
* app/pencil.c

* app/tool_options.c: cleaned up pressure sensitivity for paint
tools. I had to rename Pressure to Rate in a few tools to avoid
confusion with the Pressure option that applies to the brush.
* app/gimplut.c: indentation, no changes
--Sven
1999-10-25 Tor Lillqvist <tml@iki.fi>
* app/cursorutil.h: Uncomment the inclusion of gdkcursor.h that
should happen only with GTk+ 1.3, anyway? Why was it commented
out?
* app/tile_swap.c: Close before unlinking on Win32, too.
* libgimp/gimp.def: Updates, sorted.
* plug-ins/makefile.{cygwin,msc}: Add the gap and imagemap
plug-ins. Remove palette plug-in (what happened to it?).
Portability fixes from Hans Breuer:
* plug-ins/FractalExplorer/Dialogs.c
* plug-ins/gap/*.c:
* plug-ins/gimpressionist/gimpressionist.c:
* plug-ins/common/spheredesigner.c: Ifdefify system-dependent includes.
* plug-ins/common/psp.c: Remove an unused variable.
* plug-ins/imagemap/{imap_csim.y,imap_csim_parse.c}: Use
<string.h>, not <strings.h>.
* plug-ins/imagemap/imap_rectangle.c (rectangle_near_sash): Use
the & operator for function names to return pointers to them.
* plug-ins/winsnap/winsnap.c (sendBMPToGimp):
gimp_drawable_flush() should be called before resizing the layer
and image. Now the snapshot of a window is returned the correct
size, it's not padded in width to a multiple of four pixels.
* app/app_procs.c
* app/gdisplay_color.[ch]
* app/gdisplay_color_ui.c: make the ui usable
* app/gdisplay.c: enable cdisplay support
* modules/Makefile.am
* modules/cdisplay_gamma.c: moved gamma functionality to separate
-Yosh
* app/tile_swap.c (tile_swap_default_out): don't update a tile's swap
file position until the tile's actually been successfully written
out
* app/tile_cache.c (tile_cache_zorch_next): add test to make sure tile
was successfully swapped out before dropping it from the cache

* app/Makefile.am
* app/gimphelp.[ch]
* app/gimpui.[ch]: new files
* app/interface.[ch]
* app/preferences_dialog.[ch]
The GIMP Help System part 1: Press "F1" in any dialog to pop up
the help page for this dialog.
Moved the widget constructors from preferences_dialog.[ch] and the
query boxes from interface.[ch] to gimpui.[ch].
The dialog constructors take a help_func and a help_data
parameter and install the "F1" accelerator which emits the new
"help" signal.
The "help" signal callback calls help_func(help_data) which finally
has to call gimp_help() which in turn invokes the help browser.
Still have to find a proper way to (1) prevent "F1" being assigned
to some menu item and (2) to catch "F1" while browsing the menu
trees in order to pop up the help for the selected item.
* app/menus.c: a <Toolbox>/File/Help... menu item.
* app/commands.[ch]: a command callback for the "Help..." menu item.
* app/gimprc.[ch]: new boolean gimprc variable "use_help".
* app/info_dialog.[ch]: pass a help function and data to the info
dialog constructor.
* app/tools.[ch]: store the tools help page names in the tool info
structure. Export a special tools_help_func() which shows the help
page for the active tool.
* app/[all files calling a dialog constructor]: pass the dialog's
help page to the constructor.
Most dialogs are now created by gimp_dialog_new() which also sets
up the action_area and the WM delete event callback, so I removed
the resp. code from these files.
Fixed some minor bugs and did some other stuff but didn't change
any logic except dialog creation.
* plug-ins/helpbrowser/helpbrowser.c: don't try to call a running
help browser and don't install any menu path (all done in
app/gimphelp.[ch] now).
Fri Sep 3 22:52:26 BST 1999 Andy Thomas <alt@gimp.org>
* app/curves.c
* app/curves.h
Added indicators (x,y of mouse & x for the line) to the curves
dialog.
1999-09-01 Tor Lillqvist <tml@iki.fi>
* app/appenv.h
* libgimp/gimpmath.h: New file. Includes <math.h>. Move G_PI,
RINT(), ROUND() etc from app/appenv.h here, so plug-ins can
use them, too. Remove some commented-out old stuff in appenv.h.
* libgimp/gimp.h: Include gimpmath.h.
* libgimp/gimp.c (gimp_main): Win32: Don't install signal
handlers, we can't do anything useful in the handler ourselves
anyway (it would be nice to print out a backtrace, but that seems
pretty hard to do, even if not impossible). Let Windows inform the
user about the crash. If the plug-in was compiled with MSVC, and
the user also has it, she is offered a chance to start the
debugger automatically anyway.
* app/*several*.c: Include gimpmath.h for G_PI etc. Don't include
<math.h>, as gimpmath.h includes it.
* plug-ins/*/*many*.c: Include config.h. Don't include <math.h>.
Remove all the duplicated definitions of G_PI and rint(). Use
RINT() instead of rint().
* app/app_procs.[ch]: app_exit() takes a gboolean.
* app/batch.c
* app/commands.c
* app/interface.c: Call app_exit() with FALSE or TRUE.
* app/main.c (on_error): Call gimp_fatal_error. (main): Don't
install any signal handler on Win32 here, either.
* app/errors.c (gimp_fatal_error, gimp_terminate): Win32: Format
the message and call MessageBox with it. g_on_error_query doesn't
do anything useful on Win32, and printf'ing a message to stdout or
stderr doesn't do anything, either, in a windowing application.
1999-09-01 Tor Lillqvist <tml@iki.fi>
* app/tile_swap.c (tile_swap_open): Use _O_TEMPORARY. Removed
#ifdef, instead define the Win32-only _O_BINARY and _O_TEMPORARY
as zero if not defined.
* plug-ins/common/spheredesigner.c: Include config.h (#if
HAVE_CONFIG_H). RAND_FUNC and SRAND_FUNC are defined in that.
* app/apptypes.h: added InterpolationType enum.
* app/gimprc.[ch], app/preferences_dialog.c: replaced
cubic_interpolation flag with interpolation_type variable.
* app/pixel_region.[ch]: added pixel_region_has_alpha function.
* app/paint_funcs.c: rewrote scale_region. It now behaves
correctly on images with alpha, no longer leaves an artifact on the
right edge of images when scailing up, and runs signifigantly
faster.
* app/brush_select.c: Color brushes now appear in the brush
selector in color. Scaling is disabled for color brushes because
I can't figure out how to do it just now. Still need to fix the
toolbox to do this too.
--klm
* app/appenv.h: Define ROUND(), RINT(), SQR(), G_PI and
G_PI_4. The latter two will presumably eventually be in
GLib. RINT() calls rint() if we have it, otherwise adds 0.5 and
calls floor().
* app/*.c: Remove the multiple identical definitions of M_PI. Use
G_PI instead of M_PI. Remove ROUND() and rint() definitions. Use
RINT() instead of rint().
* app/clone.c: more cursor support.
* app/cursorutil.[ch], cursors/{bad,badmsk}: new cursor
* app/paint_core.c: fix that rounding error the right way this time.
* app/pixel_processor.c, app/pixel_region.c: Lock the tiles while
they are being processed. Only create new threads if the region
being processed is large enough to warrant it.
1999-07-22 Michael Natterer <mitschel@cs.tu-berlin.de>
* app/channel_ops.[ch]: new ui for the "Layer Offset" dialog.
* app/channels_dialog.c
* app/layers_dialog.c: major code cleanup: Folded some callbacks
into common ones, "widget" instead of "w", indentation, ...
* app/commands.c
* app/interface.[ch]
* app/global_edit.c: the query boxes must be shown by the caller
now. There's no need to split up the string for the message box
manually as the Gtk 1.2 label widget handles newlines corectly.
Added the "edge_lock" toggle to the "Shrink Selection" dialog.
Nicer spacings for the query and message boxes.
* app/ink.c: tried to grab the pointer in the blob preview but
failed. Left the code there as a reminder (commented out).
* app/menus.c: reordered <Image>/Select.
I was bored and grep-ed the sources for ancient or deprecated stuff:
* app/about_dialog.[ch]
* app/actionarea.[ch]
* app/app_procs.c
* app/brush_edit.c
* app/brush_select.c
* app/color_select.c
* app/convert.c
* app/devices.c
* app/gdisplay.c
* app/gdisplay_ops.c
* app/histogram_tool.[ch]

* app/palette_select.c
* app/paths_dialog.c
* app/pattern_select.c
* app/resize.c
* app/scale_toolc.c
* app/text_tool.c:
s/container_border_width/container_set_border_width/g,
s/sprintf/g_snprintf/g, replaced some constant string lengths with
strlen(x).
* app/bezier_select.c
* app/blend.c
* app/boundary.c
* app/errors.[ch]
* app/free_select.c
* app/gimpbrushlist.c
* app/gimprc.c
* app/iscissors.c
* app/main.c
* app/patterns.[ch]
* app/text_tool.c: namespace fanaticism: prefixed all gimp error
functions with "gimp_" and formated the messages more uniformly.
* app/gradient.c
* app/gradient_select.c: same stuff as above for the ui
code. There are still some sub-dialogs which need cleanup.
Did some cleanup in most of these files: prototypes, removed tons
of #include's, i18n fixes, s/w/widget/ as above, indentation, ...
1999-07-02 Michael Natterer <mitschel@cs.tu-berlin.de>
* app/[all tools]: the Tool structure is now allocated by a common
constructor which sets default values and provides default tool
action functions. To get rid of much code duplication there should
be a object hierarchy of tools.
* app/context_manager.c
* app/tools.[ch]: create and destroy private contexts for the
paint tools on startup and exit. They are not used yet.
* app/interface.c
* app/menus.c
* app/tools.h: num_tools is now exported in tools.h
* app/commands.c
* app/gdisplay.c
* app/menus.c: made "Toggle Selection" a toggleable menu item.
1999-06-26 Michael Natterer <mitschel@cs.tu-berlin.de>
* app/[all tool related files]
* app/commands.c
* app/disp_callbacks.c
* app/gdisplay.c
* app/gimage.c
* app/interface.c: hopefully fixed the bugs that appeared with my
last fix. And some more changes...
- Slightly changed the conditions which cause the tools to be
re-initialized on button_press events and the global
initialisation functions.
- The dialog tools now explicitly set tool->gdisp_ptr so they can
be properly hidden on display deletion.
- Create the crop info dialog only once and avoid ugly redraw bugs
by blocking the sizeentries' signal when initializing them.
- Standardized the tools_new_<tool>() functions. They are
scheduled to be moved to a common constructor in tools.c
- Various stuff...

* app/brightness_contrast.c

* app/curves.c
* app/disp_callbacks.c
* app/histogram_tool.c
* app/hue_saturation.c
* app/levels.c
* app/posterize.c
* app/threshold.c:
Factored out the cleaning up code to the tool dialog's "cancel"
callbacks because they are called from every function which is
aborting the tool. This should fix the remaining segfaults.
I probably killed a feature of "Levels". The tool wanted to
preserve it's drawable all the time, so it was possible to select
colors from other displays. If this was the intended behaviour,
please flame me and I will try to set the "preserve" flag
correctly.
* plug-ins/common/Makefile.am: "struc" was in the Makefile but not
in the directory.
1999-06-21 Michael Natterer <mitschel@cs.tu-berlin.de>
* app/context_manager.c: namespace cleanups.
* app/commands.[ch]
* app/menus.c: moved the "Toggle Selection" menu entry to "View",
sprinkled some separators and made the layers/channels/paths popup
menus consistent with Tigert's last ops buttons change.
* app/fileops.c
* app/plug_in.c: check for gdisplay_active() returning NULL in
some more places.
* app/[all tool related files]:
- Turned the ToolAction and ToolState #define's into typedef'ed
enums, so the compiler can do some more sanity checking.
- Removed one more unused global variable "active_tool_layer".
- Removed some #include's from tools.c.
- Standardized the individual tools' structure names.
- Moved showing/hiding the tool options to separate functions.
- Stuff...
* app/commands.c
* app/disp_callbacks.c
* app/gdisplay.c
* app/tools.c: fixed the segfaults which happened when the image
of one of the tools which have dialogs (levels/posterize/...) was
deleted. My approach was to do stricter sanity checking and to set
some gdisplay pointers correctly where appropriate, so I can't
tell exactly where the bug was.
The curves tool now(??) updates on every _second_ display change
only, which is really obscure.
Finding/changing the display to operate on should definitely be
done by connecting to the user context's "display_changed"
signal.
* app/gimpset.c: emit the "remove" signal _after_ removing the
pointer from the set. If this was not a bug but a feature, please
let me know, we'll need two signals then.
* README.win32: Mention using GNU gettext.
* config.h.win32: Enable NLS stuff. Remove the X11 & Unix vs. Win32
feature test macros, we use those from glibconfig.h and gdkconfig.h.
* app/makefile.msc: Use gettext. New object files.
* app/batch.c: No need to include <io.h> on Win32.
* app/errorconsole.c
* app/plug_in.c
* app/tile_swap.c: Include <glib.h> early to get Win32 feature
test macros from <glibconfig.h>.
* app/gimpset.c: Remove unnecessary (?) warning.
* app/main.c
* libgimp/stdplugins-intl.h: If no LOCALEDIR defined
(as on Win32), use the "locale" subdir in gimp_data_directory().
* app/palette.c: Open palette file in text mode.
* app/session.c
* app/text_tool.c: Use GDK's GDK_WINDOWING feature test macro
if available, not WINDOWS_DISPLAY.
* libgimp/gimpfeatures.h.win32: Correct GIMP_VERSION.
* libgimp/makefile.msc: Use gettext.
* plug-ins/makefile.msc: Use gettext. Add some missing

* configure.in: Check for mmap.
* app/makefile.msc: Depend on gimpi.lib.
* app/app_procs.c (app_init): Fix gccism: Allocate filenames (an
array with non-constant size) dynamically.
* app/{datafiles,fileops,general,install,module_db,temp_buf}.c:
Include glib.h before standard headers, because of certain obscure
details related to compiling with gcc on Win32.
(If you really want to know: glib.h defines he names of POSIXish
(but non-ANSI) functions as prefixed with underscore, because
that's how they are named in the msvcrt runtime C library we want
to use. However, defining stat as _stat causes some problems if
done after including the mingw32 <sys/stat.h>. So, it's easiest to
include <glib.h> early.)
* app/main.c: Use _stdcall and __argc, __argv with MSC, but
__attribute__((stdcall)) and _argc, _argv with gcc. Don't print
the "Passed serialization test" message on Win32. (It would open
up an otherwise unnecessary console window.)
* app/paint_funcs.c (gaussian_blur_region): Don't use variable sum
until initialized.
* app/{bezier_select,paths_dialog}.c: Include config.h and define
rint() if necessary.
* app/plug_in.c: Use _spawnv, not spawnv, on Win32 and OS/2.
* app/curves.c: colour in the previously greyscale bars to the
left and below the curve itself. Might want to take alpha and
value into account, but currently we don't. Incidentally
fixes a few redraw problems I found along the way. Done in
about an hour and a half, to show Wavey Dave what's possible :)

Changed:-
* app/bezier_select.c
* app/bezier_selectP.h
* app/cursorutil.c
* app/cursorutil.h
* app/curves.c

New:-
* cursor/mouse1_ap

* cursor/mouse1_sel
* cursor/mouse1_selm
* cursor/mouse1_selmmsk
* cursor/mouse1_selmsk
* cursor/mouse1_selp
* cursor/mouse1_selpmsk
Paths changes:-
Implemented multi-part paths.
(Import the path (RMB in paths dialog brings menu up)
http://www.picnic.demon.co.uk/tmp/gimp.path
into a 600x256 (WxH) for an example).
Can copy/paste paths.
Fully custom cursors when using the Bezier tool. A number of bug
fixes re boundary problems also fixed.
Note that heavy use is made of the modifier keys in the bezier tool.
MB1 inside a closed curve converts it to a selection. The modifiers
change how the selection interacts with any current selection (in
much the same way as the selection tool does).
MB1 + ALT on control point will move a curve, if shift modifier active
then single curve is moved.
Curves:-
In curves dialog you can now press MB1 + shift will add point to
curves dialog corresponding to the current position in
the currently selected channel. MB1 + CNTRL will add the point
to all channels. (Thanks to Carey Bunks for the initial idea).

* app/tile.c
* app/tile.h
* app/tile_manager.c
* app/tile_pvt.h
* app/paint_funcs.c:
Added Tile Row Hinting to the GIMP tile structure. Tiles
now have cheap per-row hints indicating whether each row is
all-transparent, all-opaque, a mixture, or other properties.
These hints are automatically invalidated when the tile is checked
in as dirty, and are re-evaluated on demand.
Currently only the layer compositing routines take advantage
of these hints, though there is opportunity to use them to
advantage in numerous other places.
The whole layer compositing process is typically 2x-4x faster
now, especially on subsequent renders of data which has already
had its hints calculated.
See tile.h for the explicit TileRowHint query/set interface.
The procedure to re-evaluate tile hints currently resides in
paint_funcs.c but may be exposed to other parts of the core
if necessary.
This is experimental. Please report mis-rendering problems.
* config.h.win32, README.win32: Small changes.
* tools/pdbgen/pdb/*.pdb: Include <string.h>.
* app/*_cmds.c: Autogenerated files reflect above changes.
* libgimp/makefile.msc app/makefile.msc: Various updates,
including new object files. Gtk+ directory now should be called
gtk+ (not gtk-plus). Use win32-specific gdk subdir. Glib directory
now should be called just glib.
* libgimp/gimp.def: Updates.
* libgimp/gimpfeatures.h.win32: Made current with
gimpfeatures.h.in.
* libgimp/gimpfileselection.c: Define S_ISDIR and S_ISREG if
necessary.
* tools/pdbgen/pdb/fileops.pdb: Must have a
statement (even an empty one) after a label.
* app/fileops_cmds.c: Autogenerated file reflects above changes.
* app/crop.c: Include <string.h>.
* app/{app_procs,batch,fileops,datafiles,errorconsole,general,
plug_in,temp_buf,tile_swap}.c: Test NATIVE_WIN32, not
_MSC_VER. (NATIVE_WIN32 means we are using the Microsoft C
runtime, even if we might be compiling with gcc.)
* app/fileops.c: Don't include <process.h> here.
* app/fileops.h: Do include <process.h> here.
* app/gimpparasite.c: Include config.h, guard inclusion of
<unistd.h>. (Is the inclusion of unistd.h in source files all over
the place really necessary?)
* app/ink.c: MSC doesn't handle conversion from unsigned __int64
to double, so cast to signed.
* app/lut_funcs.c: Include config.h, and define rint() if necessary.
* app/pixel_processor.c: Include config.h without "..", like in
all the other places. Include <string.h>
* app/text_tool.c: Guard the "POINTS" identifier that clashes with
<windows.h>, sigh.

* app/Makefile.am
* app/tool_options.[ch]
* app/selection_options.h
* app/tool_options_ui.h: new files.
Ok, this time it's general enough for future extensions:
- The tool options structures are organized like the gtk object
system to allow derived tool options.
- Renamed all create and reset functions to *_options_new() and
*_options_reset() to reflect this.
- Changed tools_register() again. Now it takes just a pointer to a
ToolOptions structure.
- Moved almost the entire tool options gui code to tool_options.c.
- Visually separated the common selection options from the
tool-specific ones. I'd like to do the same with opacity/paint
mode in all paint tool options but I think this needs some more
discussion.
* app/histogram_tool.c: changed packing boxes, label alignments.
* app/paintbrush.c: some more sensitive settings. The gradient
feature can now be toggled with a button. Hopefully didn't break
anything.
* app/text_tool_cmds.c: doh, XLFD stuff is in decipoints
* app/color_cmds.h: removed
* app/color_cmds.c: pdbgened file now
* app/lut_funcs.h: export ChannelLutType enum
* app/internal_procs.c: register pdbgened color procs
* app/menus.c: reverted keyboard underlines since they need more discussion

* app/gimphistogramF.h: new file containing typedef for
GimpHistogram.
* app/gimphistogram.h: moved GimpHistogram typedef to
gimphistogramF.h
* app/lut_funcs.h: include gimphistogramF.h again now that the
file actually exists.
* app/Makefile.am: build color_cmds, lut_funcs, and pixel_processor
* app/app_procs.c: feedback in the splash screen when loading
parasites.
* app/boundary.c: Optimized find_empty_segs.
* app/brightness_contrast.[ch]
* app/levels.[ch]
* app/posterize.[ch]:
moved pdb and lut calculation code. These files now contain only
GUI functions.
* app/channel.c: Optimized channel_bounds (fewer compares, better
use of registers). Use color_region instead of channel_*_segment
in channel_combine_rect. Optimized channel_combine_ellipse by
skipping pixels inside of the ellipse. Use
pixel_region_process_parallel in channel_combine_mask. Use a
GimpLut in channel_invert, and channel_sharpen.
* app/invert.c
* app/equalize.c: moved the lut functions to lut_funcs.c
* app/gimpdrawable.c, app/gimpdrawableP.h
* app/gimpimage.c, app/gimpimageP.h: removed unused gimpmatrix
variables/includes.
* app/gimplut.[ch]: added new function gimp_lut_process_inline
that operates on a single PixelRegion.
* app/gimpparasite.[ch]: new functions to save/load parasiterc
* app/parasitelist.[ch]: new functions to save/load ParasiteLists
in/from files.
* libgimp/parasite.[ch]: new functions to load/save parasites.
* app/internal_procs.c: get some procs from new location in
color_cmds.h.
* app/pixel_region.[ch]: moved pixel_regions_process_parallel
related functions to a new file.
* app/color_cmds.[ch]: new files for PDB
definitions/implementations of color correction functions.
* app/lut_funcs.[ch]: new files to hold lut creation functions.
* app/pixel_processor.[ch]: new files that contain the
pixel_regions_process_parallel routines. Added some new
capabilities that are currently unused.

Implemented the "reset tool options" feature.
- All tools register with a title string and a reset function now.
- The tool options' variables have two related <var>_d (default)
and <var>_w (widget) variables to restore the default values.
"Standardized" the tool options UI:
- Put the stuff info a frame to give a hint that the dialog's
contents will change.
- table layout, sensitive setting, spacings, borders, ...
As I had them all in my emacs simultaneously, I couldn't resist to
standardize the tools' *.c files declaration parts ;) Ansi stuff.
Wed Apr 7 23:53:22 BST 1999 Andy Thomas <alt@gimp.org>
Changed:-
* app/curves.c
Just noticed a bug that has been around for ages. The preview
update does not work in the curves dialog when free curve
mode is selected. Fixed it.
Wed Apr 7 22:44:02 BST 1999 Andy Thomas <alt@gimp.org>
Changed:-
* app/curves.c
* app/image_map.c
* app/image_map.h
Curves dialog now has "interactive feedback". Press and drag the
mouse button in the image window and a marker will appear in the
curves dialog showing the channel value at that point.
* app/Makefile.am: added gimphistogram*, histogramwidget*,
removed histogram.[ch]
* app/histogram.[ch]: removed. replaced with histogramwidget.[ch].
* app/{gimphistogramP.h, gimphistogram.h, gimphistogram.c}: new
functions that calculate histograms in parallel and perform
calculations on them.
* app/histogramwidget.[ch]: Same as old histogram.[ch], only it is
now a real widget, and it uses GimpHistograms instead of arrays of
values.
* app/curves.c: #include gimphistogram.h instead of histogram.h.
* app/equalize.c: use GimpHistogram and GimpLut.
* app/gimpbrush.c, app/gimpimage.c, app/gimpset.c: use
GTK_RUN_FIRST in calls to gimp_signal_new.
* app/histogram_tool.c, app/levels.c, app/threshold.c: modified to
use the new HistogramWidget.
* app/paint_funcs.c: removed some unused variables.
* app/preferences_dialog.c: only display the num-processor field
if we are configured --with-mp
* plug-ins/gee/gee.c: removed a couple of c++ style comments.
done in pieces, don't expect to be able to compile on Win32 from
these sources yet. Ans of course, the official version of GTk+
doesn't include the Win32 stuff yet.
* app/gimplut.[ch]: new source files that implement pixel Look Up
Table functions.
* app/Makefile.am: build gimplut.[ch]
* app/brightness_contrast.c
* app/curves.c
* app/invert.c
* app/levels.c
* app/posterize.c: Use the new lut functions. Use
pixel_region_process_parallel in the PDB versions of these routines.
* libgimp/parasite.h
* libgimp/parasite.c: new functions parasite_name and
parasite_compare.
* app/gimpdrawable.c:
* app/gimpdrawable.h: new function
gimp_drawable_get_color_at(...) returns the RGBA[color index]
value at a specified position in the drawable. Don't set the dirty
bit on the image if a new parasite is the same as the old.
* app/gimpimage.c
* app/gimpimage.h new function
gimp_image_get_color_at(...) returns the RGBA[color index]
value at a specified position in the drawable. Don't set the dirty
bit on the image if a new parasite is the same as the old.
* app/by_color_select.c
* app/color_picker.c: use the new gimp_*_get_color_at
functions instead of messing with the tiles.
* app/layer.c: fixed a minor warning.
* app/commands.c:
don't scale the image if the new size == the old size
* app/channel.c: optimized channel_bounds by only checking the
pixels in a tile if it is not already entirely within the
currently computed bounds.
Sun Feb 7 22:06:04 GMT 1999 Adam D. Moss <adam@gimp.org>
* app/dialog_handler.c

thumbnail loading. Now has a 'generate thumbnail' button.
* app/brightness_contrast.c
* app/color_balance.c
* app/curves.c
* app/hue_saturation.c: Changed some gint to gint32. It
doesn't matter right now, but it might if the optimized
CLAMP0255 gets fixed.
Sun Feb 7 15:04:23 GMT 1999 Adam D. Moss <adam@gimp.org>
* app/fileops.c: More robust and kickin' thumbnail support.

* app/tile_manager.c: Errr, I don't remember. No, seriously.
Nothing of consequence.
* app/color_balance.c: optimized by using a lookup table
* app/paint_funcs.c: parallelized apply_mask_to_region,
combine_mask_and_region, and initial_region. Use rand_r
if we are multithreaded.
Sun Jan 31 19:42:26 GMT 1999 Adam D. Moss <adam@gimp.org>
* app/tile.c app/tile_manager.c:
Fixed the tile-corruption bug which has been around
since early GIMP-1.1. When dirtying a copy-on-write
tile, a pointer to nonsense data was being returned
when the c-o-w'd tile source was swapped out to disk.
Now the c-o-w'ing routine ensures that the tile data
is correctly locked into memory before duplicating it
for dirtying.
Wed Jan 20 22:37:13 GMT 1999 Adam D. Moss <adam@gimp.org>
* app/gimpimage.c: Enabled the gimage->projection copy-on-write
hack for RGBA/GRAYA single-layer images. Masks/channels
probably don't show yet when this is active. Report strangeness.
Thanks.
1999-01-15 Federico Mena Quintero <federico@nuclecu.unam.mx>
* Updated gtk_toggle_button_set_state() to
gtk_toggle_button_set_active() in all the files.
* i18n markings from Daniel Egger (mostly removal of tags around
PDB stuff), some constification
* I went on a sprintf pogrom. Use g_snprintf or g_strdup_printf
where applicable, to prevent overflows, especially with filenames
and translated strings. suid gimp is now more secure. ;)

gimp-egger-981009-1.patch, gimp-egger-981010-1.patch
* plug-in/guillotine/guillotine.c: added the coordinates

bookkeeping without being used). Made copy_region more intelligent on
when to use tile sharing; some changes made to pixel_regions to
facilitate this. Fixed a refcount problem with xcf load and probably
a few other bugs that I've forgotten about. Added a sanity check in
set_undo_tiles to help with a problem larry is reporting with airbrush
and xinput. --sg

* app/pixel_region.c
* app/pixel_region.h: asynchronous swapin on systems with pthreads.
This version is not at all tuned, and the only interface which makes use
of it now is pixel_region_{g,s}et_{row,col}. Other functions which know
ahead of time the area that they will be needing can request that it be
asynchronously swapped in via the pixel_region_get_async() function.
Compiles and survives basic testing.
* app/paint_funcs.c: Shaved about 25% off the time spent in
combine_inten_[a_]and_inten_a_pixels() - yay.
* app/xcf.c: Removed 'M' and '.' debugging spew

Fixed copy-on-write path of copy_region which was sometimes
crashing with Scott's new tile scheme.
* app/tile_manager.c:
Added some sanity warnings.
* app/xcf.c:
Fixed copy-on-write tile loading which was causing crashes
with Scott's new tile scheme. Ref balance count seems funny
still.

* app/undo.c: Lots of changes to the way tools are intialized and
accessed. All information about a tool type is now contained in a
single ToolInfo array. There are still some small issues to
adress about tool groups and we need some way of getting menu
ordering/grouping to work better (plug-ins need this too). There

* app/curves.[ch]: Changed the *_initalize function prototypes from
gpointer to GDisplay, to allow better type chacking and provide a
uniform interface for all the dialog tools.
Modified tile swapping to preswap dirty tiles, using a thread if
threads are enabled in configure or a gtk_timeout if they're not. The
code appears stable but could use improvement. Be careful when
working in here; there are four sets of semaphores and getting the
locking wrong will cause deadlocks or tile corruption. I'll try to
write up a document describing what's going on in here sometime soon.

* redid the error message handling. g_message now calls message_box or prints
to console depending on whether the no_interface is set or not. gimp-message
is also exported to the PDB as a wrapper to g_message, and libgimp has a new
API: gimp_message. libgimp also overrides g_message for all plugins. Converted
lots of messages in app/* to g_message. Made script-fu a little friendlier.
* updated the regex code from grep 2.2
