Changed the semantics of GIMP_EXTENSION and (to some extent) of
2003-06-19 Michael Natterer <mitch@gimp.org>
Changed the semantics of GIMP_EXTENSION and (to some extent)
of GIMP_PLUGIN:
The old meaning of EXTENSION was "I live in the toolbox" and
PLUGIN meant "I take RUN-MODE,IMAGE,DRAWABLE args (but only if I
am invoked interactively)". This is completely useless, since
living in the toolbox means having "<Toolbox>" in the menu_path
and taking RUN-MODE,IMAGE,DRAWABLE means just that, regardless of
what type of procedure we are.
The new meaning of GIMP_PLUGIN is just "I am an ordinary procedure,
I am invoked, do my job and finish", while GIMP_EXTENSION means
"I will install temporary procedures and I will keep running to
keep them available".
(A GIMP_EXTENSION *must* call gimp_extension_ack() now to tell the
core that it's ready to run, or the core will block waiting for
the message !!!).
* configure.in: bumped version number to 1.3.16.
* libgimpbase/gimpprotocol.h: increased protocol version number so
old extensions will refuse to load.
* app/gui/plug-in-commands.c (plug_in_run_cmd_callback): don't
blindly pass RUN-MODE,IMAGE,DRAWABLE to GIMP_PLUGIN procedures but
look at their parameters and pass them either RUN-MODE, or
RUN-MODE,IMAGE, or RUN-MODE,IMAGE,DRAWABLE.
* app/pdb/procedural_db.c: cleaned up, better error reporting,
replaced an impossible error message by g_return_if_fail()
* app/plug-in/plug-in-message.c (plug_in_handle_proc_install):
better error messages.
* app/plug-in/plug-in-params.c: allocate parameter arrays using
g_new0() so we don't have to worry about uninitialized stuff
later.
* app/plug-in/plug-in-run.c (plug_in_run): wait for
gimp_extension_ack() installation confirmation for ALL extensions,
not just for automatically started ones.
* app/plug-in/plug-ins.c: cleanup.
* libgimp/gimp.[ch]: cleaned up and API-documented massively. Made
all magic values given in the GPConfig message static and added
accessor functions for them. Added gimp_tile_width()/height().
Added new function gimp_extension_enable() which turns on
asynchronous processing of temp_proc run requests without having
to enter an endless gimp_extension_process() loop. Moved all
private functions to the end of the file. Added tons of
g_return_if_fail() all over the place. Call gimp_run_procedure2()
from gimp_run_procedure() instead of duplicating the
code. Indentation, spacing, stuff...
* libgimp/gimptile.[ch]: removed gimp_tile_width()/height().
* libgimp/gimpdrawable.c
* libgimp/gimppixelrgn.c
* libgimp/gimptile.c: use the gimp_tile_width()/height() accessor
functions.
* libgimp/gimp.def: added gimp_extension_enable.
* libgimp/gimpmenu.c: removed evil code which connected to
_readchannel manually and use gimp_extension_enable() for watching
temp_procs.
* plug-ins/helpbrowser/helpbrowser.c: removed the same evil code
here and call gimp_extension_enable(). Call gimp_extension_ack()
to let the core know that the temp_proc is installed.
* plug-ins/script-fu/script-fu.c: made all procedures except the
permanently running "extension_script_fu" ordinary GIMP_PLUGIN
procedures.
* plug-ins/common/curve_bend.c
* plug-ins/common/plugindetails.c
* plug-ins/common/screenshot.c
* plug-ins/common/uniteditor.c
* plug-ins/common/winclipboard.c
* plug-ins/dbbrowser/dbbrowser.c
* plug-ins/gfli/gfli.c
* plug-ins/twain/twain.c
* plug-ins/webbrowser/webbrowser.c
* plug-ins/winsnap/winsnap.c: made them all ordinary GIMP_PLUGIN
procedures and renamed them from "extension_*" to "plug_in_*".
Random cleanups.
* app/widgets/gimphelp.c
* plug-ins/maze/maze_face.c: call "plug_in_web_browser" now.

Initial space invasion commit in GIMP
All babl formats now have a space equivalent to a color profile,
determining the format's primaries and TRCs. This commit makes GIMP
aware of this.
libgimp:
- enum GimpPrecision: rename GAMMA values to NON_LINEAR and keep GAMMA
as deprecated aliases, add PERCEPTUAL values so we now have LINEAR,
NON_LINEAR and PERCPTUAL for each encoding, matching the babl
encoding variants RGB, R'G'B' and R~G~B~.
- gimp_color_transform_can_gegl_copy() now returns TRUE if both
profiles can return a babl space, increasing the amount of fast babl
color conversions significantly.
- TODO: no solution yet for getting libgimp drawable proxy buffers in
the right format with space.
plug-ins:
- follow the GimpPrecision change.
- TODO: everything else unchanged and partly broken or sub-optimal,
like setting a new image's color profile too late.
app:
- add enum GimpTRCType { LINEAR, NON_LINEAR, PERCEPTUAL } as
replacement for all "linear" booleans.
- change gimp-babl functions to take babl spaces and GimpTRCType
parameters and support all sorts of new perceptual ~ formats.
- a lot of places changed in the early days of goat invasion didn't
take advantage of gimp-babl utility functions and constructed
formats manually. They all needed revisiting and many now use much
simpler code calling gimp-babl API.
- change gimp_babl_format_get_color_profile() to really extract a
newly allocated color profile from the format, and add
gimp_babl_get_builtin_color_profile() which does the same as
gimp_babl_format_get_color_profile() did before. Visited all callers
to decide whether they are looking for the format's actual profile,
or for one of the builtin profiles, simplifying code that only needs
builtin profiles.
- drawables have a new get_space_api(), get_linear() is now get_trc().
- images now have a "layer space" and an API to get it,
gimp_image_get_layer_format() returns formats in that space.
- an image's layer space is created from the image's color profile,
change gimpimage-color-profile to deal with that correctly
- change many babl_format() calls to babl_format_with_space() and take
the space from passed formats or drawables
- add function gimp_layer_fix_format_space() which replaces the
layer's buffer with one that has the image's layer format, but
doesn't change pixel values
- use gimp_layer_fix_format_space() to make sure layers loaded from
XCF and created by plug-ins have the right space when added to the
image, because it's impossible to always assign the right space upon
layer creation
- "assign color profile" and "discard color profile" now require use
of gimp_layer_fix_format_space() too because the profile is now
embedded in all formats via the space. Add
gimp_image_assign_color_profile() which does all that and call it
instead of a simple gimp_image_set_color_profile(), also from the
PDB set-color-profile functions, which are essentially "assign" and
"discard" calls.
- generally, make sure a new image's color profile is set before
adding layers to it, gimp_image_set_color_profile() is more than
before considered know-what-you-are-doing API.
- take special precaution in all places that call
gimp_drawable_convert_type(), we now must pass a new_profile from
all callers that convert layers within the same image (such as
image_convert_type, image_convert_precision), because the layer's
new space can't be determined from the image's layer format during
the call.
- change all "linear" properties to "trc", in all config objects like
for levels and curves, in the histogram, in the widgets. This results
in some GUI that now has three choices instead of two.
TODO: we might want to reduce that back to two later.
- keep "linear" boolean properties around as compat if needed for file
pasring, but always convert the parsed parsed boolean to
GimpTRCType.
- TODO: the image's "enable color management" switch is currently
broken, will fix that in another commit.
