* app/display/gimpdisplayshell-render.c: (compute_sample),
(render_image_tile_fault), (render_image_tile_fault_one_row):
refactored to use arrays of tiles/source pixels instead of individual
variables, also modified the order of the 0..8 numbers to sorted
in increasing row-major order.
svn path=/trunk/; revision=23353
* app/display/gimpdisplayshell-render.c: replaced bilinear
interpolation from next larger pyramid level with a boxfilter
of the next larger pyramid level.
This is probably the last update to the quality of the display
in GIMP 2.4.
svn path=/trunk/; revision=23349
* app/display/gimpdisplayshell-render.c: added a bilinear filtering
like weighting of neighbourhood pixels for approximating the
downsampling from the next larger level in the projection mipmap.
Also some general code cleanup.
svn path=/trunk/; revision=23278
* app/display/gimpdisplayshell-render.c: Fixed regression at zoom
levels > 100%, and moved some floating point code out of the worker
function.
svn path=/trunk/; revision=23251
2007-06-21 Martin Nordholts <martinn@svn.gnome.org>
* app/display/gimpdisplayshell-render.c (gimp_display_shell_render):
Refactored the two helper functions render_image_init_info(_full)?
and always use the shell base scale for the shell->mask. Fixes
bug #448417.
svn path=/trunk/; revision=22822
2007-06-06 Sven Neumann <sven@gimp.org>
* app/core/gimpprojection.[ch]: minor API cleanup. Use
horizontal
and vertical scale to determine the pyramid level to use.
* app/display/gimpdisplayshell-draw.c
* app/display/gimpdisplayshell-render.c: follow the API change.

2007-06-06 Martin Nordholts <martinn@svn.gnome.org>
Implemented an image pyramid for the GimpProjection. An image pyramid
caches a projection at several sizes, causing the rendering code not to
have to swap in all tiles of a (potentially) large image; it can use
small versions of the projection if the user is zoomed out.
The image pyramid also imroves visual quality, especially at zoom levels
where there is a pyramid level that matches perfectly (i.e. at e.g. 50%,
25%, and 12.5% zoom). A step on the right track for bug #76096.
* app/core/gimpprojection.[ch]: Adjusted to make use of an image
pyramid. GimpProjection now keeps an array of TileManager:s, one per
pyramid level. Renamed _alloc_tiles to _alloc_levels.
* app/display/gimpdisplayshell-draw.c: (gimp_display_shell_draw_area):
Use the right GimpProjection level when drawing
* app/display/gimpdisplayshell-render.c: (render_image_init_info_full):
Setup RenderInfo with level in mind
* app/base/tile-manager.[ch]: Extended API a bit, nothing complicated.
* app/base/tile-manager-private.h (struct _TileManager): Keep a pointer
to the level below for use in an image pyramid.

2007-03-14 Sven Neumann <sven@gimp.org>
* app/display/gimpdisplayshell-render.c: sprinkled some const
qualifiers and removed obscure shift code in favor of letting the
compiler do this optimization.
svn path=/trunk/; revision=22121
2007-03-09 Michael Natterer <mitch@gimp.org>
* app/core/core-types.h: include "libgimpmath/gimpmathtypes.h"

2006-04-07 Sven Neumann <sven@gimp.org>
* app/core/gimpdrawable.[ch]: renamed gimp_drawable_data() to
gimp_drawable_get_tiles().
[lots of files]: changed accordingly.
2006-03-17 Sven Neumann <sven@gimp.org>
* app/display/gimpdisplayshell-render.c
* app/display/gimpdisplayshell.[ch]
* app/tools/gimpforegroundselectoptions.[ch]
* app/tools/gimpforegroundselecttool.c: allow to use red, green or
blue for the selection preview used by the foreground selection tool.
2005-07-31 Sven Neumann <sven@gimp.org>
* app/display/gimpdisplayshell-render.c
* app/display/gimpdisplayshell.[ch]: removed the overlay again.
This needs to be done differently.
* app/tools/gimpforegroundselecttool.c: changed accordingly.
2005-07-30 Sven Neumann <sven@gimp.org>
* app/display/gimpdisplayshell-render.c
* app/display/gimpdisplayshell.[ch]: renamed overlay to mask and
added a different overlay implementation that will be needed to
finish the new foreground-select tool.
* app/tools/gimpforegroundselecttool.c: changed accordingly.
2005-07-30 Sven Neumann <sven@gimp.org>
* app/display/gimpdisplayshell-render.c
* app/display/gimpdisplayshell.[ch]: added
gimp_display_shell_set_overlay(); allows to overlay a mask over the
display to visualize a selection.
* app/tools/gimpforegroundselecttool.[ch]: use the new functionality
to display the selection. Escape cancels the tool, Enter applies the
selection.
2005-05-09 Sven Neumann <sven@gimp.org>
* app/base/tile-manager.c: inline tile_manager_get_tile_num().
* app/display/gimpdisplayshell-render.c (render_image_tile_fault):
reverted one of the changes I did here earlier.
2005-04-27 Sven Neumann <sven@gimp.org>
* app/base/tile-manager.c (tile_manager_get_tile): removed
redundant check.
* app/display/gimpdisplayshell-render.c: don't access the next
tile if we are at the end of the render loop anyway.
2005-04-27 Sven Neumann <sven@gimp.org>
* app/core/gimpimage-colormap.[ch]: declared the return value of
gimp_image_get_colormap() as const.
* app/display/gimpdisplayshell-render.c: added some const qualifiers.
2004-10-01 Sven Neumann <sven@gimp.org>
* app/display/gimpdisplayshell-callbacks.c: no need to include
gimpdisplayshell-render.h here.
* app/display/gimpdisplayshell-draw.c
* app/display/gimpdisplayshell-render.[ch]
* app/display/gimpdisplayshell.[ch]: added an API to highlight a
rectangle (specified in image coordinates). Actually it doesn't
highlight but dims the area outside the rectangle.
* app/tools/gimpcroptool.c: use the new functionality to show the
area to be cropped. Fixes bug #93360.
2004-09-03 Sven Neumann <sven@gimp.org>
* libgimpbase/Makefile.am
* libgimpbase/gimpchecks.[ch] added gimp_checks_get_shades().
* app/base/temp-buf.c
* app/display/gimpdisplayshell-render.c
* libgimpwidgets/gimppreviewarea.c: use the new function instead
of replicating these numbers in three different places.
2004-09-02 Sven Neumann <sven@gimp.org>
* app/display/gimpdisplayshell-render.c (check_combos): light and
dark check color were swapped for GIMP_CHECK_TYPE_GRAY_CHECKS.
* libgimpwidgets/gimppreviewarea.[ch]: added "check-size" and
"check-type" properties and draw the checkerboard accordingly.
2004-02-04 Michael Natterer <mitch@gimp.org>
* app/display/gimpdisplayshell-render.c (struct RenderInfo)
(render_image_accelerate_scaling): use gdouble instead of gfloat
for x and y scale factors so gfloat's limited precision can't add
up to off-by-one pixel errors. Fixes display artefacts (missing
updates) at the bottom and right sides of updated areas at certain
irrational zoom factors like 1:3.
2003-11-21 Michael Natterer <mitch@gimp.org>
* libgimpwidgets/gimpcolordisplaystack.h: forgot to declare
gimp_color_display_stack_clone().
* app/display/gimpdisplayshell.[ch]: replaced the GList of
GimpColorDisplays by a single GimpColorDisplayStack.
* app/display/gimpdisplayshell-render.c
(gimp_display_shell_render): changed accordingly.
* app/display/gimpdisplayshell-filter.[ch]: reduced API to a
single function, gimp_display_shell_filter_set(), which exchanges
the whole filter stack. Idle update the display on
GimpColorDisplayStack::update().
* app/display/gimpdisplayshell-filter-dialog.[ch]: changed
accordingly. Return the created dialog instead of assigning
shell->filters_dialog.
* app/gui/view-commands.c (view_display_filters_cmd_callback): set
shell->filters_dialog here and raise it it if already
exists. Don't use the dialog factory to create it because it's a
transient dialog for the display which does not need to be session
managed.
* app/gui/dialogs-constructors.[ch]
* app/gui/dialogs.c: removed display filter dialog stuff.
2003-11-15 Sven Neumann <sven@gimp.org>
* app/display/gimpcanvas.c (gimp_canvas_gc_new): no need to set
colors on the GCs that use GDK_INVERT.
* app/display/gimpdisplayshell-render.c (gimp_display_shell_render):
micro cleanup.
2003-11-10 Sven Neumann <sven@gimp.org>
* app/display/gimpcanvas.[ch]
* app/tools/gimpdrawtool.[ch]: moved GC from the the draw tool to
GimpCanvas. Added wrappers around GDK drawing functions and do all
canvas drawing by means of these new functions.
* app/display/gimpdisplayshell-appearance.c
* app/display/gimpdisplayshell-render.c
* app/display/gimpdisplayshell.c
* app/tools/gimpcroptool.c
* app/tools/gimpfuzzyselecttool.c: draw using the new GimpCanvas
functions.
2003-04-04 Sven Neumann <sven@gimp.org>
* app/display/gimpdisplayshell-render.c: applied a patch from
Pedro Gimeno that fixes the display render problems at high zoom
levels (bug #109933).
2003-03-21 Sven Neumann <sven@gimp.org>
* app/display/gimpdisplayshell-scale.c: don't emit the "scaled"
signal from gimp_display_shell_scale_setup(). Emit it explicitely
from gimp_display_shell_scale_resize() instead.
* app/display/gimpdisplayshell-scroll.c: call
gimp_display_shell_scale_setup() after scrolling in order to
update scrollbars and rulers.
* app/display/gimpdisplayshell-callbacks.c
* app/display/gimpdisplayshell-handlers.c: emit the "scaled" signal
explicitely.
* app/display/gimpdisplayshell-render.c: minor optimizations.
* app/display/gimpdisplayshell.c: minor cleanup.
2003-02-26 Michael Natterer <mitch@gimp.org>
* app/core/gimpviewable.[ch]: added "gchar *stock_id" to the
GimpViewable struct. It is used by the GUI if the get_preview()
functions return NULL. Default to GTK_STOCK_DIALOG_QUESTION.
* app/core/gimptoolinfo.[ch]: set the tool's stock_id. Removed
the cached GdkPixbuf. Don't implement any preview function
so the GUI uses the stock_id.
* app/tools/tool_manager.c: removed GdkPixbuf creation, removed
the #warning about the buggy way we created the pixbuf.
* app/gui/dialogs-constructors.c
* app/gui/image-menu.c
* app/tools/gimpcroptool.c
* app/tools/gimphistogramtool.c
* app/tools/gimpimagemaptool.c
* app/tools/gimpmeasuretool.c
* app/tools/gimptransformtool.c
* app/widgets/gimptoolbox.c: use viewable->stock_id instead
of tool_info->stock_id.
* app/core/gimpbrush.c
* app/core/gimpgradient.c
* app/core/gimpimagefile.c
* app/core/gimpundo.c: simplified get_preview() implementations:
- never scale previews up, only down.
- don't render white or checks backgrounds but simply return
TempBufs with alpha and let the preview system do its job.
- don't add padding but simply return previews smaller than
requested.
* app/display/gimpdisplayshell-render.[ch]: added
"render_blend_white", a 2d lookup table for blending on white,
just as the check lookup tables. Added "render_white_buf".
* app/widgets/gimppreview.[ch]: changed a lot:
- don't render the preview's border into the buffer.
- added "GdkGC *border_gc" and draw the preview's border in expose()
using gdk_draw_rectangle().
- added "GdkPixbuf *no_preview_pixbuf" and create it in
gimp_preview_real_render() if gimp_viewable_get_preview()
returned NULL.
- factored the actual preview rendering out to
gimp_preview_render_to_buffer(). Added configurable background
rendering for the preview itself and it's padding area
(the area the preview is larger than the buffer returned
by gimp_viewable_get_preview()).
- changed gimp_preview_render_and_flush() to
gimp_preview_render_preview() and added "inside_bg" and
"outside_bg" parameters.
- use the new render buffers for blending on white.
* app/widgets/gimpbrushpreview.c
* app/widgets/gimpbufferpreview.c
* app/widgets/gimpdrawablepreview.c
* app/widgets/gimpgradientpreview.c
* app/widgets/gimpimagepreview.c
* app/widgets/gimppalettepreview.c
* app/widgets/gimppatternpreview.c: don't create large white
TempBufs to center the previews in but simply set the TempBuf's
offsets to get them centered. Simplified & cleaned up many preview
render functions. Pass the correct GimpPreviewBG modes to
gimp_preview_render_preview().
* app/widgets/gimpcellrendererviewable.[ch]: new GtkCellRenderer
class derived from GtkCellRendererPixbuf which knows how
to use gimp_viewable_get_preview_size() and renders the
viewable's stock item if no preview can be created.
* app/widgets/gimpcontainertreeview.c: added a GtkTreeCellDataFunc
which creates the preview pixbuf if needed so we don't create it
unconditionally upon item insertion. Fixed preview size assertion
to use GIMP_PREVIEW_MAX_SIZE, not "64". Block "selection_changed"
while reordering the selected item.
* app/widgets/gimpcontainerview.c: cosmetic.
* app/widgets/gimpimagefilepreview.[ch]
* app/widgets/gimptoolinfopreview.[ch]
* app/widgets/gimpundopreview.[ch]: removed because the default
implementation is good enough.
* app/widgets/Makefile.am
* app/widgets/widgets-types.h
* app/widgets/gimppreview-utils.c: changed accordingly.
* app/gui/dialogs-constructors.[ch]
* app/gui/dialogs-menu.c
* app/gui/dialogs.c
* app/gui/image-menu.c
* app/gui/toolbox-menu.c: register grid and tree view variants
of the document history.
Unrelated:
* app/gui/gui.c (gui_exit_finish_callback): disconnect from
signals earlier.
* app/gui/user-install-dialog.c: create the "tool-options" subdir
of the user's ~/.gimp-1.3 directory.
2003-02-24 Michael Natterer <mitch@convergence.de>
* app/display/gimpdisplay-foreach.[ch]: removed
gimp_displays_invalidate() again.
* app/display/gimpdisplayshell-render.c: don't call it.
* app/display/gimpdisplayshell-handlers.c
(gimp_display_shell_check_notify_handler): put the call to
gimp_display_shell_expose_full() back I "optimized" away a few
days ago.
2003-02-21 Sven Neumann <sven@gimp.org>
* app/display/gimpdisplay-foreach.[ch]: added new function
gimp_displays_invalidate() which queues a redraw on all displays
by calling gimp_display_shell_expose_full().
* app/display/gimpdisplayshell-render.c (render_setup_notify):
invalidate all displays when the transparency type or size changes.
* app/tools/gimptexttool.c (text_tool_button_press): readded some
code I accidentally removed in my last commit.
* app/text/gimptextlayout.c (gimp_text_layout_new): always set the
font size but make sure it is at least 1.
2003-02-21 Sven Neumann <sven@gimp.org>
* app/display/gimpdisplayshell-render.c (render_image_rgb):
replaced a for-loop with a call to memcpy().
* app/display/gimpdisplay.c: use g_memdup() instead of g_new()
followed by memcpy().
2003-01-05 Manish Singh <yosh@gimp.org>
* many files in app, modules and libgimp*: cleanup, removed unecessary
G_OBJECT() casts. Should do the same for plug-ins, when more of them
get undeprecated.
2002-12-04 Sven Neumann <sven@gimp.org>
* app/display/gimpdisplayshell-render.c (render_image_tile_fault):
removed useless assignments.
* plug-ins/common/aa.c: removed wrong assertions that caused the
plug-in to crash on images with odd width or height (#100344).
Added support for RGB images as well as alpha channel while I was
on it.
2002-11-21 Michael Natterer <mitch@gimp.org>
* app/base/tile-cache.[ch]: added tile_cache_init() and
tile_cache_exit() as public functions.
* app/base/base.c: call them. Connect to GimpBaseConfig's
notify::tile-cache-size.
* app/core/gimpimage.c: connect to notify::transparency-type and
notify::transparency-size and call
gimp_image_invalidate_layer_previews() in the callback.
* app/display/gimpdisplay-foreach.[ch]: removed
gdisplays_expose_full().
* app/display/gimpdisplayshell-handlers.c: connect to
notify::transparency-type and notify::transparency-size and expose
the shell in the callback.
* app/display/gimpdisplayshell-render.[ch]: added render_init()
and render_exit() functions and connect to
notify::transparency-type and notify::transparency-size for
setting up the render buffers.
* app/gui/gui.c: call the new functions instead of render_setup().
Connect to notify::show-tool-tips.
* app/gui/preferences-dialog.c: copy values between the global
config object and its local clone only when they have changed.
Wrap setting of lots of values in g_object_[freeze|thaw]_notify().
Added lots of mnemonics.
* app/gui/resolution-calibrate-dialog.c: added mnemonics.
* app/widgets/gimppropwidgets.c: g_object_set() the values edited
by the gimp_prop_coordinates() much less often by remembering the
old values and setting them only when they have changed.
