Instead, handle the drawing offset generically by offsetting the
cairo_t in two places in the callers, and only pass the width and
height available for drawing.
Call cairo_surface_flush() before reading or writing a surface's
pixels directly, and use cairo_surface_mark_dirty() after writing
pixels directly, so we don't read old pixels, and our written pixels
get actually used.
Don't fail when checking for availability of buffers in
gimp_view_render_to_surface(). The buffers will be gone when quitting
GIMP while in s-w-m and we don't want to print a warning every time
that happens.

* app/widgets/gimpviewrenderer.c (gimp_view_renderer_real_draw):
if the surface has CAIRO_CONTENT_COLOR_ALPHA, render it on a
checkerboard background.
* app/widgets/gimpviewrenderergradient.[ch]: just draw the
gradient with alpha-transparency instead of doing the blend on
the
checkerboard here.

2007-11-13 Michael Natterer <mitch@gimp.org>
* app/widgets/gimpviewrenderer.c (gimp_view_renderer_draw): use
cairo_save()/cairo_restore() around calling the virtual function
instead of restoring the clipping area manually.

2007-11-13 Michael Natterer <mitch@gimp.org>
* app/widgets/gimpviewrenderervectors.c
(gimp_view_renderer_vectors_draw): naive port to Cairo. Somebody
should check if this isn't better done with proper curve_to()
drawing using the original vectors data instead of interpolation.
* app/widgets/gimpviewrenderer.c (gimp_view_renderer_draw): reset
clipping before drawing the border because a subclass' draw()
might have done additional clipping.

* app/widgets/gimpcontainercombobox.c
* app/widgets/gimpcontainertreeview.c
* app/widgets/gimplayertreeview.c
* app/widgets/gimpview.c: removed calls to
gimp_view_renderer_unrealize() which are not needed anymore
because we don't allocate a GC in the renderer any longer.
* app/widgets/gimpcellrendererdashes.c: removed a redundant
cast.
svn path=/trunk/; revision=24039
2007-11-01 Sven Neumann <sven@gimp.org>
* app/widgets/gimpviewrenderer.c (gimp_view_renderer_draw):
removed code that draws a diagonal line across a renderer
without
context. Emit a warning instead; this shouldn't happen any
longer.
svn path=/trunk/; revision=24038
2007-06-08 Sven Neumann <sven@gimp.org>
* app/core/gimpviewable.h: #define GIMP_VIEWABLE_PRIORITY_IDLE,
which is even lower than G_PRIORITY_LOW.
* app/core/gimpundo.c
* app/widgets/gimpviewrenderer.c: create previews with
GIMP_VIEWABLE_PRIORITY_IDLE so that they are run after the
projection has been invalidated.
svn path=/trunk/; revision=22743
2006-08-31 Michael Natterer <mitch@gimp.org>
* app/core/gimpgradient.[ch] (gimp_gradient_has_fg_bg_segments):
new funtion which returns TRUE if any of the gradient's segments
refer to FG of BG.
(gimp_gradient_segment_get_left_color_type)
(gimp_gradient_segment_set_left_color_type)
(gimp_gradient_segment_get_right_color_type)
(gimp_gradient_segment_set_right_color_type): new accessors for
the new GimpGradientColor stuff.
(gimp_gradient_segment_split_midpoint)
(gimp_gradient_segment_range_flip)
(gimp_gradient_segment_range_replicate): split, flip and replicate
the segments' color_types too.
* app/widgets/gimpviewrenderer.[ch]: added virtual functions
::set_context() and ::invalidate() and call them.
* app/widgets/gimpviewrenderergradient.[ch]: implement the virtual
functions. Connect to the context's "foreground-changed" and
"background-changed" signals if the gradient contains FG or BG
colors and invalidate the renderer whenever they change.
* app/core/gimp-gradients.c: removed signal connections which
invalidated the gradients on FG/BG changes of the user context.
2006-08-29 Michael Natterer <mitch@gimp.org>
Changed GimpViewable preview rendering to have a context to get
FG/BG/whatever from. Use the context to enable dynamic FG/BG
colors in gradients. Fixes bug #127676 and bug #352214. Addresses
bug #128367 (doesn't fix it because there's no loading/saving and
no GUI yet).
* app/core/core-enums.[ch]: added enum GimpGradientColor to enable
specifying gradient colors in terms of foreground and background.
* app/core/gimpgradient.[ch]: added color_type members to the
GimpGradientSegment struct and honor them in
gimp_gradient_get_color_at(). Added GimpContext parameters to all
functions which finally call get_color_at().
* app/core/gimp-gradients.c: use the new method to implement the
builtin gradients.
* app/core/gimpviewable.[ch]: added GimpContext parameters to all
get_preview() and get_pixbuf() functions.

* tools/pdbgen/pdb/image.pdb: added tons of GimpContext members
and parameters, implement GimpDocked::set_context() in many
widgets. Pass these locally remembered contexts to GimpViewable
functions. Did some minor cleanups on the way. There are still
some minor FIXMEs around where the code uses a NULL context (which
is allowed by the APIs)
* app/pdb/drawable_cmds.c
* app/pdb/gradient_cmds.c
* app/pdb/gradients_cmds.c
* app/pdb/image_cmds.c: regenerated.
