* app/core/gimp-transform-utils.c (gimp_transform_matrix_flip_free):
applied patch from Joao S. O. Bueno that fixes bug #160339.
2004-10-27 Michael Natterer <mitch@gimp.org>
* app/core/gimp-transform-utils.[ch]. switch from x1,y1,x2,y2
bounding boxes to x,y,width,height ones. Added
gimp_transform_matrix_flip_free(). Renamed some parameters to be
consistent with others. Some internal cleanup.
* app/tools/gimpperspectivetool.c
* app/tools/gimpscaletool.c
* app/tools/gimpsheartool.c
* tools/pdbgen/pdb/drawable_transform.pdb
* tools/pdbgen/pdb/transform_tools.pdb: changed accordingly.
* tools/pdbgen/pdb/drawable_transform.pdb
* tools/pdbgen/pdb/transform_tools.pdb: guard all transform
wrappers with if(gimp_drawable_mask_intersect(...)), also the
ones which don't need the returned bounding box.
* tools/pdbgen/pdb/drawable_transform.pdb: renamed some parameters
and added gimp_drawable_transform_matrix() which takes the 9
coefficients of a 3x3 matrix for ultimate flexibility ;)
* app/pdb/drawable_transform_cmds.c
* app/pdb/internal_procs.c
* app/pdb/transform_tools_cmds.c
* libgimp/gimpdrawabletransform_pdb.[ch]: regenerated.
2004-03-31 Michael Natterer <mitch@gimp.org>
* app/core/gimp-transform-utils.c
(gimp_transform_matrix_perspective): make sure 0.0/0.0 results
in 1.0, not NaN.
* app/core/gimpdrawable-transform.c
(gimp_drawable_transform_tiles_affine): instead of returning NULL
if the transformation shrinks the tiles completely away, return at
least the pixel (or the row or column of pixels) which best covers
the sub-pixel area of the transform result:
- Changed rounding of the transformed coordinates from RINT()
to floor()/ceil() so we don't cut off sub-pixel portions of the
transform result.
- Force the minimal size if the changed rounding didn't help.
Fixes bug #138117.
Also added paranoia code which falls back to clip_result if the
passed matrix produces NaN coordinates (copied the FINITE() macro
from image_cmds.c).
2003-09-15 Sven Neumann <sven@gimp.org>
* app/core/gimpdrawable-transform-utils.[ch]: removed...
* app/core/gimp-transform-utils.[ch]: ...and added under new names
because these functions are not at all related to GimpDrawable.
Changed the function names accordingly.
* app/tools/gimpperspectivetool.c
* app/tools/gimprotatetool.c
* app/tools/gimpscaletool.c
* app/tools/gimpsheartool.c
* app/vectors/gimpstroke.c
* app/vectors/gimpvectors.c
* tools/pdbgen/pdb/transform_tools.pdb: changed accordingly.
* app/pdb/transform_tools_cmds.c: regenerated.
2003-09-11 Sven Neumann <sven@gimp.org>
* app/core/gimpdrawable-transform-utils.[ch]: added new function
gimp_drawable_transform_matrix_flip().
* app/vectors/gimpstroke.[ch]
* app/vectors/gimpvectors.c: don't push the complex GimpItem
transformation API down to GimpStroke. Instead setup the matrices
in GimpVectors and use a simpler API for GimpStroke.
* app/vectors/gimpvectors-import.c: changed accordingly.
* app/vectors/gimpvectors-export.c: close the <path> element.
2003-04-04 Sven Neumann <sven@gimp.org>
Applied a patch from Øyvind Kolås that adds supersampling to the
transform operations (bug #109817):
* app/base/tile-manager-private.h
* app/base/tile-manager.[ch]: cache the last accessed tile and use
it to optimize read_pixel_data_1().
* app/core/gimpdrawable-transform-utils.c
* app/core/gimpdrawable-transform.c: changed the resampling
behavior when scaling down.
2002-02-19 Michael Natterer <mitch@gimp.org>
Fixed#10466 (disappearing pixels when rotating by 90 deg):
* app/core/gimpdrawable-transform.c: when transforming backwards
to find the destination line's sub-pixel source coordinates, we
need to transform the pixels _center_, not it's upper left corner.
* app/core/gimpdrawable-transform-utils.[ch]: added
gimp_drawable_transform_matrix_rotate_center() which takes double
center coordinates instead of an integer pixel bounding box.
* app/tools/gimptransformtool.[ch]: use double instead of int for
all coordinates except the original bounding box.
* app/tools/gimprotatetool.c: use double whenever touching the
"center" value, so it can be sub-pixel positioned.
2001-11-19 Michael Natterer <mitch@gimp.org>
* app/display/gimpdisplay-foreach.c: forgot to commit last time.
Transform stuff cleanup:
* app/core/Makefile.am
* app/core/core-types.h
* app/core/gimpdrawable-transform.[ch]: new files implementing
the actual transform functions cut from tools/gimptransformtool.*.
* app/core/gimpdrawable-transform-utils.[ch]: new files implementing
transform matrix assembly utility functions.
* app/tools/gimptransformtool.[ch]: removed the stuff here. cleanup.
* app/tools/transform_options.[ch]: removed all stuff which does
not belong here, e.g. the transform_tool_* functions and the
global "transform_options" variable. Works like all other tool
options now.
* app/tools/gimpfliptool.[ch]
* app/tools/gimpperspectivetool.[ch]
* app/tools/gimprotatetool.[ch]
* app/tools/gimpscaletool.[ch]
* app/tools/gimpsheartool.[ch]: massive code removal because
we can use core/gimpdrawable-fransform* functions now. cleanup.
* tools/pdbgen/Makefile.am
* tools/pdbgen/groups.pl: added new PDB group "transform_tools".
* tools/pdbgen/pdb/tools.pdb: removed the transform stuff here...
* tools/pdbgen/pdb/transform_tools.pdb: and added *much*
simplified versions which use the new core/gimpdrawable-transform*
utilities.
* app/pdb/Makefile.am
* app/pdb/transform_tools_cmds.c: new file.
* app/pdb/internal_procs.c
* app/pdb/tools_cmds.c: regenerated.
* libgimp/Makefile.am
* libgimp/gimp_pdb.h
* libgimp/gimptransformtools_pdb.[ch]: new files.
* libgimp/gimptools_pdb.[ch]: regenerated.
