2003-02-07 Michael Natterer <mitch@gimp.org> Added object properties for almost all tool_options values and registered lots of enums with the type system: Part I (enum and type cleanup): * app/core/core-enums.[ch] * app/core/core-types.h: removed InternalOrientaionType and register GimpOrientationType. Register GimpChannelOps. Removed GimpToolOptionsGUIFunc. * app/xcf/xcf-private.h: added XcfOrientationType with the same values as the old InternalOrientationType * app/xcf/xcf-load.c * app/xcf/xcf-save.c: translate between GimpOrientationType and XcfOrientationType. * app/core/gimpdrawable-transform-utils.[ch] * app/core/gimpdrawable-transform.[ch] * app/core/gimpimage-crop.c * app/core/gimpimage-duplicate.c * app/core/gimpimage-guides.c * app/core/gimpimage-resize.c * app/core/gimpimage-scale.c * app/core/gimpimage.h * app/display/gimpdisplayshell.c * tools/pdbgen/stddefs.pdb * tools/pdbgen/pdb/transform_tools.pdb: changed accordingly. * app/pdb/guides_cmds.c * app/pdb/transform_tools_cmds.c * libgimp/gimpenums.h * libgimpproxy/gimpproxytypes.h * plug-ins/script-fu/script-fu-constants.c * tools/pdbgen/enums.pl: regenerated. * libgimptool/gimptoolenums.[ch]: added GimpTransformGridType. * libgimptool/gimptooltypes.h: removed GimpToolOptionsResetFunc, added GimpToolOptionsGUIFunc. Part II (tool options changes): * app/config/gimpconfig-utils.c (gimp_config_reset_properties): don't reset object properties because they have NULL as default value. * app/widgets/gimppropwidgets.[ch]: added gimp_prop_[enum|boolean]_radio_frame_new(), gimp_prop_paint_mode_menu_new() and gimp_prop_scale_entry_new(), which are all needed by the new tool options GUI code. * app/tools/tool_options.[ch]: removed the "reset_func" since the virtual reset() method is used now. * app/paint/gimpairbrushoptions.[ch] * app/paint/gimpcloneoptions.[ch] * app/paint/gimpconvolveoptions.[ch] * app/paint/gimpdodgeburnoptions.[ch] * app/paint/gimperaseroptions.[ch] * app/paint/gimppaintoptions.[ch] * app/paint/gimpsmudgeoptions.[ch]: added properties all over the place and removed the widget and default_value members from the structs. Renamed some values (e.g. s/type/clone_type/). Don't #include <gtk/gtk.h>. * app/paint/gimpairbrush.c * app/paint/gimpclone.c * app/paint/gimpconvolve.c * app/paint/gimpdodgeburn.c * app/paint/gimperaser.c * app/paint/gimppaintbrush.c * app/paint/gimppaintcore-stroke.c * app/paint/gimppaintcore.c * app/paint/gimppencil.c * app/paint/gimpsmudge.c * app/paint/paint-types.h * app/paint/paint.c: changed accordingly. Don't #include <gtk/gtk.h>. * tools/pdbgen/pdb/paint_tools.pdb: changed accordingly. * app/pdb/paint_tools_cmds.c: regenerated. * app/tools/gimpblendoptions.[ch] * app/tools/gimpbucketfilloptions.[ch] * app/tools/gimpcolorpickeroptions.[ch] * app/tools/gimpcropoptions.[ch] * app/tools/gimpflipoptions.[ch] * app/tools/gimpinkoptions.c * app/tools/gimpmagnifyoptions.[ch] * app/tools/gimpmeasureoptions.[ch] * app/tools/gimpmoveoptions.[ch] * app/tools/gimptextoptions.c * app/tools/paint_options.[ch] * app/tools/selection_options.[ch] * app/tools/transform_options.[ch]: ditto: added properties and removed widget and default_value stuff. Removed most reset functions. Use gimp_prop widgets all over the place, renamed some values as above. * app/tools/Makefile.am * app/tools/gimpairbrushtool.c * app/tools/gimpblendtool.c * app/tools/gimpbucketfilltool.c * app/tools/gimpbycolorselecttool.c * app/tools/gimpclonetool.c * app/tools/gimpconvolvetool.c * app/tools/gimpcroptool.c * app/tools/gimpdodgeburntool.c * app/tools/gimperasertool.c * app/tools/gimpfliptool.c * app/tools/gimpfuzzyselecttool.c * app/tools/gimpmagnifytool.c * app/tools/gimpmovetool.c * app/tools/gimpselectiontool.c * app/tools/gimpsheartool.c * app/tools/gimpsmudgetool.c * app/tools/gimptransformtool.c * app/tools/gimpvectoroptions.c: changed accordingly. Ported the paint_options GUI constructors to gimp_prop widgets. * app/widgets/gimpselectioneditor.c * app/gui/tool-options-dialog.c: changed accordingly.

This tool flips the specified drawable if no selection exists. If a selection
|
|
exists, the portion of the drawable which lies under the selection is cut from
|
|
the drawable and made into a floating selection which is then flipd by the
|
|
specified amount. The return value is the ID of the flipped drawable. If there
|
|
was no selection, this will be equal to the drawable ID supplied as input.
|
|
Otherwise, this will be the newly created and flipped drawable. The flip type
|
|
parameter indicates whether the flip will be applied horizontally or
|
|
vertically.

Perform a possibly non-affine transformation on the specified drawable.

$help = <<'HELP';
|
|
This tool performs a possibly non-affine transformation on the specified
|
|
drawable by allowing the corners of the original bounding box to be arbitrarily
|
|
remapped to any values. The specified drawable is remapped if no selection
|
|
exists. However, if a selection exists, the portion of the drawable which lies
|
|
under the selection is cut from the drawable and made into a floating selection
|
|
which is then remapped as specified. The interpolation parameter can be set to
|
|
TRUE to indicate that either linear or cubic interpolation should be used to
|
|
smooth the resulting remapped drawable. The return value is the ID of the
|
|
remapped drawable. If there was no selection, this will be equal to the
|
|
drawable ID supplied as input. Otherwise, this will be the newly created and
|
|
remapped drawable. The 4 coordinates specify the new locations of each corner
|
|
of the original bounding box. By specifying these values, any affine
|
|
transformation (rotation, scaling, translation) can be affected. Additionally,
|
|
these values can be specified such that the resulting transformed drawable will
|
|
appear to have been projected via a perspective transform.
