Scripts must be able to pass values to procedures even if they have no
idea what the actual parameter type is (item, uchar, layer mask), to
the script it's all just numbers anyway.
paste as brush, paste as pattern, select to new brush, select to new pattern
fill selection outline, fill path, stroke selection, distort, rounded rectangle
indexed color conversion, merge visible layers, new guide, new guide (by percent)
image properties, newsprint, fractal explorer, sample colorize, new layer
metadata editor (just a button), spyroplus (only common buttons)
Turn all ID param specs into object param specs (e.g. GimpParamImageID
becomes GimpParamImage) and convert between IDs and objects in
gimpgpparams.c directly above the the wire protocol, so all of app/,
libgimp/ and plug-ins/ can deal directly with objects down to the
lowest level and not care about IDs.
Use the actual object param specs for procedure arguments and return
values again instead of a plain g_param_spec_object() and bring back
the none_ok parameter.
This implies changing the PDB type checking functions to work on pure
integers instead of IDs (one can't check whether object creation is
possible if performing that check requires the object to already
exist).
For example gimp_foo_is_valid() becomes gimp_foo_id_is_valid() and is
not involved in automatic object creation magic at the protocol
level. Added wrappers which still say gimp_foo_is_valid() and take the
respective objects.
Adapted all code, and it all becomes nicer and less convoluted, even
the generated PDB wrappers in app/ and libgimp/.
It's just too weird to be public. Remove its properties from the wire
protocol and from pluginrc. Instead, have all GParamSpecs' flags on
the wire and in pluginrc, so we can use stuff like
GIMP_PARAM_NO_VALIDATE.
Port the remaining few places to GIMP_PROC_ARG_STRING().
I'm sure something is broken now wrt UTF-8 validation,
will add tighter checks in the next commit.
Something during the port to gimp-drawable-edit (commit
233ac80de1) broke add-bevel.scm when
the thickness is high enough for the selection to become empty.
Add an explicit check for a selection while constructing the bump-
map layer.
carve-it.scm, chrome-it.scm: apply slightly modified patch from Carol
Spears which replaces hardcoding round brush names by creating a brush
on the fly and setting its radius.
Also fixed both scripts to not use deprecated color API which is
even completely gone from master.
Spyrogimp has been rewritten in Python with more features.
Note: this commit should not be backported to gimp-2-10 since we will
keep the old plug-in around (in case its API is used by older scripts in
particular). But let's turn over a new leaf with future GIMP 3 and only
keep the new plug-in.
... from menus.
The script-fu version is still available through pdb (for scripts) and
even in the action search. But in menus, only the new Python version
will be shown. Also update the description and name of the old version
to make clear it is deprecated in favor of the new plug-in.
Finally rename the new version to simply "plug-in-spyrogimp" (dropping
the "-plus" part as we should consider it as a replacement rather than
as another plug-in, which the "plus" would imply). Anyway the old one
was called "script-fu-spyrogimp", so there is no name clash.
While at it, do some trailing whitespace cleaning in the new plug-in.
(cherry picked from commit 8729f9a662)
Commented out the inactive plug-ins registry: no point linking to a dead page.
Added links to the roadmap page, main wiki page, and the bug tracker. Placed
the link to the bug tracker one level up from '<Image>/Help/GIMP Online'
to make it more visible.
script-fu used to query the information of every PDB procedure on
startup, in order to get the number of parameters for each
procedure. This was done so that nullary procedures were defined
in such a way as to accept (and ignore) any number of arguments
(and at least one of the scripts we ship relies on this behavior).
However, this requires expensive back-and-forth communication with
the main GIMP process, which notable slowed down script-fu's
startup, and had a non-negligible impact on GIMP's startup time.
Instead, avoid querying procedure information, and implement the
special behavior for nullary procedures at call time. We do this
by defining, in addition to the "strict" gimp-proc-db-call
procedure, a "permissive" -gimp-proc-db-call internal procedure,
and using the latter to call the predefined PDB procedures.
Increase the percision of the "position" property of
guides-new-percent.scm to two decimal places. Currently, it only
accepts integers, which limits its accuracy to 100px.
I am going to forbid plug-ins from being installed directly in the root
of the plug-ins/ directory. They will have to be installed in a
subdirectory named the same as the entry point binary.
This may seem useless for our core plug-ins which are nearly all
self-contained in single binaries, but this is actually a necessary
restriction to eliminate totally the DLL hell issue on Windows. Moving
core plug-ins in subfolders is only a necessary consequence for it.
When working on the current image, enclose the script actions in an undo group.
When working with a copy of the image, disable the undo stack of the new image
at the beginning of the script and reenable it at the end.
