For generated brushes, dynamic input is applied on top of the set hardness as a factor.
For pixmaps, it influences the amount of blur applied to the stamp. Be warned, process is slow
for large pixmaps. The odd feature previously advertised as hardness is left in but disabled.
If I figure out what it should be exposed as, it might be made available again.

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.

* 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.
svn path=/trunk/; revision=27913
* app/gegl/gimpoperationpointlayermode.c
(gimp_operation_point_layer_mode_process): Implemented Erase, Anti
Erase, Color Erase and Replace. These are not normal layer modes
and handle alpha in their own way. In addition to this, the
behavior of Replace doesn't map very well to GEGL which uses
infinite sized "layers".
Completely works the same:
o Erase
o Anti Erase
o Color Erase
Works different but similar:
o Replace
* app/paint-funcs/paint-funcs.[ch]: Expose
paint_funcs_color_erase_helper() so it can be used in the
GimpOperationPointLayerMode implementation. Once the migration is
complete this function can be moved entirely to the op and be
tailored to work on premultiplied data.

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.

Bug 547967 – Improve app/paint-funcs/ maintainability
Applied patch from Luidnel Maignan that splits the legacy code
for
layer modes into new files.
* app/paint-funcs/Makefile.am
* app/paint-funcs/layer-modes.[ch]
* app/paint-funcs/paint-funcs-utils.h: new files with code taken
from ...
* app/paint-funcs/paint-funcs-generic.h
* app/paint-funcs/paint-funcs.c: ... these two files.

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.
svn path=/trunk/; revision=26896
2008-09-01 Sven Neumann <sven@gimp.org>
* app/paint-funcs/paint-funcs.[ch]: added clear_region().
* app/base/tile-manager-crop.c
* app/core/gimpchannel.c
* app/core/gimpimage-merge.c
* app/core/gimpmaskundo.c
* app/core/gimpprojection-construct.c: use it instead of calling
color_region() with a zero color.
svn path=/trunk/; revision=26826
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.
svn path=/trunk/; revision=26779
2008-08-25 Sven Neumann <sven@gimp.org>
* 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
2008-08-12 Sven Neumann <sven@gimp.org>
* app/paint-funcs/paint-funcs.c (replace_inten_pixels): applied
a
slightly modified version of the patch from Luidnel Maignan as
attached to bug #105568. Fixes incorrect alpha treatment in
plug-in selection masking.
svn path=/trunk/; revision=26524
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.
