Jens Lautenbacher <jtl@gimp.org> 2000-12-18 Sven Neumann <sven@gimp.org> Jens Lautenbacher <jtl@gimp.org> * app/Makefile.am * app/gimpbrushlistP.h * app/gimpbrushpipeP.h * app/gimpobjectP.h: removed these three files * app/parasitelistP.h * app/channels_dialog.c * app/docindex.c * app/gimpdrawable.c * app/gimpdrawableP.h * app/gimpimage.c * app/gimpimageP.h * app/gimplist.[ch] * app/gimpobject.c * app/gimpobject.h * app/gimpsetP.h: changed according to header removal * app/airbrush.c * app/brush_select.[ch] * app/brushes_cmds.c * app/gimpbrush.[ch] * app/gimpbrushgenerated.[ch] * app/gimpbrushlist.[ch] * app/gimpbrushpipe.[ch] * app/gimpcontextpreview.c * app/paint_core.c * app/paintbrush.c * app/pencil.c * tools/pdbgen/pdb/brushes.pdb: Big Brushes Cleanup. The GimpBrush* object hierarchy and the file formats were broken by "design". This made it overly difficult to read and write pixmap brushes and brush pipes, leading to the situation that The GIMP was not able to read it's very own file formats. Since the GimpBrush format did support arbitrary color depths, the introduction of a file format for pixmap brushes was unnecessary. The GimpBrushPixmap object is dead. GimpBrush has an additional pixmap temp_buf and handles pixmap brushes transparently. The file format of pixmap brushes is not any longer a grayscale brush plus a pattern, but a simple brush with RGBA data. The old brushes can still be loaded, but the .gpb format is deprecated. GimpBrushPipe derives from GimpBrush. The fileformat is still a text header, followed by a number of brushes, but those brushes are stored in the new GimpBrush format (no pattern anymore). The pipe does not care about the depth of the contained GimpBrushes, so we get grayscale BrushPipes for free. Since the brush loader still loads the old format, old .gih files can also still be loaded. Since the brushes in the GimpBrushPipe do not any longer contain a pointer to the pipe object, we do only temporarily switch brushes in the paint_core routines. This is not very elegant, but the best we can do without a major redesign. * app/patterns.[ch]: changed the loader to work with a filedescriptor instead of a filehandle to make it work with the new brush loading code. * plug-ins/common/.cvsignore * plug-ins/common/Makefile.am * plug-ins/common/plugin-defs.pl * plug-ins/common/gih.c: new plug-in that saves GIH files in the new format (loader will follow soon) * plug-ins/common/gpb.c: removed since Pixmap Brushes are no longer supported as a special file format. * plug-ins/common/gbr.c: load and save brushes in the new brush format which allows RGBA brushes too. * plug-ins/common/pat.c: load and save grayscale patterns too

Port to glib/gtk+ 2.0 episode I (every segfault has it's beginning) 2001-07-24 Michael Natterer <mitch@gimp.org> Port to glib/gtk+ 2.0 episode I (every segfault has it's beginning) * configure.in: require glib/gtk+ >= 1.3.7, commented out the gtkxmhtml stuff. From now on, you will need glib, pango, atk and gtk+ HEAD from CVS to hack or use GIMP HEAD. Beware, it crashes randomly :) * app/core/Makefile.am * app/core/gimpmarshal.list: new file plus rules to generate gimpmarshal.[ch] from it. * app/core/* * app/tools/* * app/widgets/* * libgimpwidgets/*: started to use the glib object system. All core/ objects are still gtk objects however. All signals are created using g_signal_new(). There are many gtk+ artefacts left. Finally, we will _not_ use the gtk_signal_foo() wrappers and friends any more. * app/colormaps.c * app/devices.[ch] * app/disp_callbacks.c * app/errorconsole.c * app/file-save.[ch] * app/interface.c * app/module_db.c * app/nav_window.c * app/ops_buttons.c * app/scroll.c * app/user_install.c * app/gui/about-dialog.c * app/gui/brush-editor.c * app/gui/brushes-commands.c * app/gui/color-notebook.c * app/gui/colormap-dialog.c * app/gui/dialogs-commands.c * app/gui/dialogs-constructors.c * app/gui/file-commands.c * app/gui/file-dialog-utils.c * app/gui/file-new-dialog.c * app/gui/file-open-dialog.[ch] * app/gui/file-save-dialog.c * app/gui/gradient-editor.c * app/gui/gradients-commands.c * app/gui/image-commands.c * app/gui/info-dialog.[ch] * app/gui/layer-select.c * app/gui/layers-commands.c * app/gui/menus.c * app/gui/offset-dialog.c * app/gui/palette-editor.c * app/gui/palettes-commands.c * app/gui/patterns-commands.c * app/gui/preferences-dialog.c * app/gui/resize-dialog.[ch] * app/gui/splash.c * app/gui/tips-dialog.c * app/gui/tool-options-dialog.c * app/gui/toolbox.c * app/gui/tools-commands.c * libgimp/gimpbrushmenu.c * libgimp/gimpmenu.c * libgimp/gimppatternmenu.c * libgimp/gimpui.c * libgimpbase/gimpenv.c: tons and tons of changes like "const gchar*", switch from GdkDeviceInfo to GdkDevice (very incomplete and currently disables), lots of s/gtk_signal/g_signal/, removal/replacement of deprecated stuff, s/GtkSignalFunc/GCallback/ and lots of small changes and fixes while I was on it, zillions of warnings left... * modules/Makefile.am: disabled the water color selector temporarily (XInput issues). * plug-ins/Makefile.am * plug-ins/common/.cvsignore * plug-ins/common/Makefile.am * plug-ins/common/plugin-defs.pl: simply excluded all plug-ins which did not build (including Script-Fu). They are trivial to fix.
