* app/display/gimpdisplayshell-render.c: removed const qualifiers
to fix compilation on Solaris 8 (bug #479817).

* app/display/gimpdisplayshell-render.c: oops - managed to miss the
mask rendering.

2007-09-23 Simon Budig <simon@gimp.org>
* app/display/gimpdisplayshell-render.c: use Bresenham stepping
for the y-direction as well.
Fixes bug #474509.
Retired old and unused functions.

* app/display/gimpdisplayshell-render.c: implement
bresenham-like stepping for interpolating the view in
x-direction. Since I now know how it is supposed to work
the y direction will follow shortly.
Adresses bug #474509.
svn path=/trunk/; revision=23617
* app/display/gimpdisplayshell-render.c: (render_image_tile_fault),
(render_image_tile_fault_one_row): clone the middle row/column when
walking off the source drawable during downscaling. Probably fixes bug
#469567.
svn path=/trunk/; revision=23521
* app/display/gimpdisplayshell-render.c: (render_image_tile_fault):
use nearest neighbour resampling when rendering for a 1byte per pixel
drawable (ony happens when interacting with the SIOX tool, and then
the buffer is a indexed; not a greyscale buffer), fixes bug #472027.
svn path=/trunk/; revision=23424
2007-08-31 Raphael Quinet <raphael@gimp.org>
* app/display/gimpdisplayshell-render.c (render_image_tile_fault):
do not use anti-aliasing when the zoom is exactly 200%. Fixes bug
#472150. Also miscellaneous cosmetic changes.
svn path=/trunk/; revision=23423
* app/display/gimpdisplayshell-render.c: swapped center and middle
terms around (now center means horizontal (betwen left and right )and
middle means vertical (between top and bottom)).
svn path=/trunk/; revision=23363
* app/display/gimpdisplayshell-render.c: (compute_sample): removed
a temporary variable, simplified logic slightly.
(render_image_tile_fault, render_image_tile_fault_one_row): moved
sum computation out of loop.
svn path=/trunk/; revision=23362
* app/display/gimpdisplayshell-render.c: Replaced signed integres with
unsigned ones for weights etc to gain some additional bits of
precision. Enabled anti-aliasing for zoomlevels between 100% and 200%
to improve the smoothness of the display at the levels where the size
differences between pixels yields the most distracting artifacts.

quality.
* app/display/gimpdisplayshell-render.c:
(compute_sample): reshuffle a bit of the fixed point induced
shifting to allow higher precision.
(render_image_tile_fault): remove need to disable box-filter
for some non square zoom ratios that was needed before
compute_sample cleanup.
, (render_image_tile_fault_one_row): fetch source sample #1
from the correct tile.
svn path=/trunk/; revision=23360
* app/display/gimpdisplayshell-render.c: added a static global
variable with configuration.
(compute_sample): moved common computation of alpha*weight factors
for channel out of loop.
svn path=/trunk/; revision=23355
* 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.

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.

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.

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.

2005-07-30 Sven Neumann <sven@gimp.org>

added a different overlay implementation that will be needed to
finish the new foreground-select tool.

2005-07-30 Sven Neumann <sven@gimp.org>
* app/display/gimpdisplayshell-render.c

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().

area to be cropped. Fixes bug #93360.
2004-09-03 Sven Neumann <sven@gimp.org>
