...in non-interactive cases.
gimp_export_image () handles various
tasks like rasterizing NDE filters. It only
runs in interactive cases however, so if the
users calls gimp-file-save the filters are
not exported.
Since Jehan removed the hidden dialogue
in 0dc9ff7c, we can now safely call
gimp_export_image () in all cases to make
image export more consistent. This step is
also preparation for setting up the new
API with GimpExportOptions.
...from GimpChoice.
0b2d8fed let us display GimpChoice
options as IntRadioFrames. Therefore, we
can convert a number of plug-in parameters
that were being built manually to use
GimpChoice instead. This decreases the
amount of GUI code and makes the
non-interactive inputs more descriptive.
With the new API introduced int d1c4457f,
we next need to port all plug-ins using
the argument macros to functions.
This will allow us to remove the macros
as part of the 3.0 API clean-up.
Port all plug-ins to retrieve the layers
directly from the image rather than
having them passed in. This resolves some
issues with introspection and sets the
foundation for future API work.
Resolves#10932
Since GIMP distinguishes between saving
XCF and exporting image like PNG,
we should change the PDB to show
export rather than save in the function
calls.
Code that checked if an image was NULL was run
*after* the variable was used in a function,
gimp_image_resize_to_layers (). This patch moves
the NULL check before the function call is made.
Additionally, we now verify there are at least two axis
before trying to access indexes in the naxis array.
If we leave a space between the macro name and opening parenthese for argument
lists, the args are not considered macro args (which will be discovered when
using it). I experienced this issue while testing code on some plug-in
yesterday, so thought I might as well fix all these broken macros for casting to
the specific GimpPlugIn subclass, so that we won't have a next time.
Switching to the cfitsio library's fits_read_img () function in 03ea666f
caused RGB FITS images to be read in upside down per SiriL developers and
NASA standards (odd, since cfitsio is maintained by NASA). This flips them back.
The developers of SiriL sent me some RGB FITS images that rendered incorrectly
after d4f42076. These must be read in as
planes rather than individual rows.
Switch to NASA-maintained cfitsio library for loading/exporting FITS images.
This allows us to import compressed FITS files (GZIP, HCOMP, PLIO, RICE) in
8/16/32 bit and float/double precision. It also simplifies export code using
the built-in cfitsio APIs.
- This is unneeded in all import procedures. See previous commit. Note though
that this is not because of a change in previous commit. This was already
useless previously. The file set with this PDB function was overridden by the
core anyway (i.e. even before the previous commits).
In app/file/file-import.c:file_import_image(), the imported file is correctly
set (so there is no need to set it from plug-in, which anyway libgimp's
gimp_image_set_file() was not doing) and the XCF file is reset to NULL
(rendering the call to gimp_image_set_file() in a GimpLoadProcedure useless).
- Similarly, this is a useless call in export procedures because
app/file/file-save.c:file_save() overrides such call too. I could only see one
such case for JPEG export, which was quite useless.
- Finally in other types of plug-ins, setting a non-XCF file extension was
interfering with the save feature (similarly to commit e6e73e14c7). I only
fixed the screenshot implementations doing such a thing.
- I left a few usages which will have to be looked at more in details later.
Hence avoiding the stderr messages. These are going to be localized with
centrally installed catalogs "gimp*-std-plugins", "gimp*-script-fu" and
"gimp*-python".
We now handle core plug-in localizations differently and in particular,
with kind of a reverse logic:
- We don't consider "gimp*-std-plugins" to be the default catalog
anymore. It made sense in the old world where we would consider the
core plug-ins to be the most important and numerous ones. But we want
to push a world where people are even more encouraged to develop their
own plug-ins. These won't use the standard catalog anymore (because
there are nearly no reasons that the strings are the same, it's only a
confusing logic). So let's explicitly set the standard catalogs with
DEFINE_STD_SET_I18N macro (which maps to a different catalog for
script-fu plug-ins).
- Doing something similar for Python plug-ins which have again their own
catalog.
- Getting rid of the INIT_I18N macro since now all the locale domain
binding is done automatically by libgimp when using the set_i18n()
method infrastructure.
As explained in previous commits, the _peek_ call is advantageous
because:
- It is less bug-prone as we don't have to handle freeing the string. In
all the cases I changed, I even spotted at least 2 cases where we were
leaking a string (in file-mng, `temp_file_name` is never freed; and we
were also leaking in an error case of gfig).
- As a consequence of the previous point: simpler code with less lines.
- In local file cases, the _peek_ variant does not even need to allocate
an additional string.
- In other case, if we query several times the path, it is allocated
once and cached so it stays efficient.
- When possible, working on the GFile rather than on a path string may
be more robust. For instance I changed one g_unlink() into a
g_file_delete(). Actually most reading/writing should be done with the
GIO API when possible, but I didn't want to change too much code
logics on this commit.
This commit just changes our saving API (i.e. the GimpSaveProcedure
class) to take an array of drawables as argument instead of a single
drawable.
It actually doesn't matter much for exporting as the whole API seems
more or less bogus there and all formats plug-ins mostly care only
whether they will merge/flatten all visible layers (the selected ones
don't really matter) or if the format supports layers of some sort. It
may be worth later strengthening a bit this whole logics, and maybe
allow partial exports for instance.
As for saving, it was not even looking at the passed GimpDrawable either
and was simply re-querying the active layer anyway.
Note that I don't implement the multi-selection saving in XCF yet in
this commit. I only updated the API. The reason is that the current
commit won't be backportable to gimp-2-10 because it is an API break. On
the other hand, the code to save multi-selection can still be backported
even though the save() API will only pass a single drawable (as I said
anyway, this argument was mostly bogus until now, hence it doesn't
matter much for 2.10 logics).
and in an attack of madness, changes almost all file plug-in
code to use GFile instead of filenames, which means passing
the GFile down to the bottom and get its filename at the very
end where it's actually needed.
And always pass URIs to all file procedures, the ones what didn't
register as "handles remove" will only ever get local file:// URIs.
Change all file plug-ins (also legacy ones) to expect URIs instead
of filenames, and convert to local paths in the plug-in.
The wire protocol should now be almost 100% clean of non-UTF-8 strings.
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.
...in both the core and libgimp.
Images now know what the default mode for new layers is:
- NORMAL for empty images
- NORMAL for images with any non-legacy layer
- NORMAL_LEGAVY for images with only legacy layers
This changes behavior when layers are created from the UI, but *also*
when created by plug-ins (yes there is a compat issue here):
- Most (all?) single-layer file importers now create NORMAL layers
- Screenshot, Webpage etc also create NORMAL layers
Scripts that create images from scratch (logos etc) should not be
affected because they usually have NORMAL_LEGACY hardcoded.
3rd party plug-ins and scripts will also behave old-style unless they
get ported to gimp_image_get_default_new_layer_mode().
with proper value names. Mark most values as _BROKEN because they use
weird alpha compositing that has to die. Move GimpLayerModeEffects to
libgimpbase, deprecate it, and set it as compat enum for GimpLayerMode.
Add the GimpLayerModeEffects values as compat constants to script-fu
and pygimp.
and clean up the formatting of the call and the lines around it. Now
we can check the various (disabled) export options for regressions
again by changing a single line in gimp_export_image().
- Add new enum GimpComponentType which contains u8, u16, u32 etc.
- Change GimpPrecision to be u8-linear, u8-gamma, u16-linear etc.
- Add all the needed formats to gimp-babl.c
- Bump the XCF version to 5 and make sure version 4 with the old
GimpPrecision enum values is loaded correctly
This change blows up the precision enums in "New Image" and
Image->Precision so we can test all this stuff. It is undecided what
format will be user-visible options in 2.10.
