Bug 571628 – Scaling image to 25% turn background from white to
grey
* app/paint-funcs/scale-region.c (pixel_average2): fixed
right-shift
for GRAYA pixels.
svn path=/trunk/; revision=28025
2009-01-17 Michael Natterer <mitch@gimp.org>
* all files with a GPL header and all COPYING files:
Change licence to GPLv3 (and to LGPLv3 for libgimp).
Cleaned up some copyright headers and regenerated the parsers in
the ImageMap plugin.

Bug 557950 – Scaling in Gimp 2.6 is much slower than in Gimp 2.4
* app/paint-funcs/scale-region.c: don't do multi-pass scaling
when
we are scaling up.
svn path=/trunk/; revision=27462
2008-10-24 Sven Neumann <sven@gimp.org>
* app/paint-funcs/scale-region.c (scale): use the inverse of the
scale factor so that we can multiply instead of dividing in the
loops.

Applied 'gimp-decimate.diff' as announced on the mailing-list:
* app/gimp-log.[ch]: added log domain "scale".
* app/paint-funcs/scale-region.c: replaced decimation routines
with box filters. Only use the decimation routines to pre-scale
the image, always apply the interpolation for the final step.

2008-08-26 Sven Neumann <sven@gimp.org>
* app/paint-funcs/scale-region.c: further simplified the code
path
that is executed when a brush is scaled up. We don't need to
scale
in several steps here.
svn path=/trunk/; revision=26780
2008-08-26 Sven Neumann <sven@gimp.org>
* app/paint-funcs/scale-region.c: removed some unused parameters
from the code that is used for brush scaling. Added sanity
checks.

* app/paint-funcs/scale-region.c: use PixelSurround to access
the
source pixels in a more efficient way.
svn path=/trunk/; revision=26768
2008-08-25 Sven Neumann <sven@gimp.org>
* app/paint-funcs/scale-region.c: don't scale in several steps
if
interpolation is GIMP_INTERPOLATION_NONE.
svn path=/trunk/; revision=26760
2008-08-24 Sven Neumann <sven@gimp.org>
* app/paint-funcs/scale-region.c (scale) (scale_pr): use a
constant to decide if we should decimate or interpolate.
svn path=/trunk/; revision=26736
2008-08-24 Sven Neumann <sven@gimp.org>
* app/paint-funcs/scale-region.c: instead of iterating over
tiles
manually and using write_pixel_data_1() to write the data, use
pixel_region_process() to iterate over the destination.
svn path=/trunk/; revision=26735
2008-08-24 Sven Neumann <sven@gimp.org>
* app/paint-funcs/scale-region.c (scale): sprinkled with const
qualifiers. Moved calculations out of the loops.
svn path=/trunk/; revision=26733
2008-08-24 Sven Neumann <sven@gimp.org>
* app/paint-funcs/scale-region.c (scale): removed optimization
of
the case where the source and dest regions are the same size.
This
should not happen any longer.
svn path=/trunk/; revision=26732
2008-08-24 Sven Neumann <sven@gimp.org>
* app/paint-funcs/scale-region.c (determine_scale): avoid
unnecessary scaling when scaling factor is 2^n.
(pixel_average): replaced with optimized pixel averager from
tile-pyramid.c (from the gimp-2-4 branch with some minor
corrections).
svn path=/trunk/; revision=26731
2008-08-23 Sven Neumann <sven@gimp.org>
* app/paint-funcs/scale-region.c (scale): replaced code that
copies pixels from one tile-manager to another by a call to
copy_region().
svn path=/trunk/; revision=26730
2008-08-13 Sven Neumann <sven@gimp.org>
* app/paint-funcs/scale-region.c: applied patch from Geert
Jordaens to fix scaling artifacts in top row (bug #464466).
svn path=/trunk/; revision=26534
2008-08-04 Sven Neumann <sven@gimp.org>
* app/paint-funcs/scale-region.c: applied patch from Geert
Jordaens as attached to bug #464466. Improves quality of
scaling,
in particular down-scaling.
