In addition to the requested DXGI variants we also load the older
D3DF versions, including handling of the signed versions.
We also set signed when the pixelformat flag DDPF_BUMPDUDV (added in
the previous commit) is set.
This adds support for loading RGBA DDS images with 16- and 32-bit per
channel. Loading is supported for 16-bit half float, 32-bit float,
16 and 32-bit unsigned and signed int.
This supports both the DX10 formats and the D3D FOURCC versions.
16- and 32-bit per channel images with less than 4 channels are not
yet supported.
When saving a PDF, you have the option to export layers as pages.
This works for a single layer group that contains multiple layers.
However, the option is disabled because the plug-in only checks
"top level" layers.
This patch adds code to check if the single layer is a layer group,
then enables the option if there are more than one layer in that group.
This completes commit 685c8bde99 where the http:// scheme was automatically
transformed into https:// in some cases, in particular while typing (when
pasting for instance, it was still possible to add an http URL). So let's block
"toggled" signal handlers when the URL is explicitely edited to prevent this
annoying issue.
(cherry picked from commit b991f8b361)
While exiv2/gexiv2 could be able to load metadata from JXL files
directly, success is not guaranteed (depends on version and
configuration, for example support could be disabled or compressed
metadata could not work).
Loading metadata via libjxl should work all the time.
It is also important not to display dialog to rotate the image
according the orientation from EXIF, because in case of JXL,
the orientation is stored in codestream and it has priority.
Certain dds images can have non-zero unexpected pitch_or_linsize values.
Until now we were only computing this ourselves in case it was zero.
Let's just always compute it and print an error to the terminal if it
differs from the value in the file.
A sample can be found in Galactic Civilizations 3: Bokeh_Hex.dds.
This change also allows us to safely load the poc in security issue
ZDI-CAN-22093 as that issue was apparently only caused by an invalid
value of pitch_or_linsize.
Optimize dds loading a bit by moving code that doesn't change outside
the loop:
1. The number of bits to be shifted when the source isn't exactly 8 or
16 bits depends on bytes per sample and isn't changing inside the loop.
2. Use rowstride variable to compute width * d->bpp once.
3. The check for rowstride > hdr->pitch_or_linsize doesn't change
inside the loop so move it out.
Inside the loop we only check the DDSD_PITCH flag once and move both
the size check and the fread check inside it.
There were 2 issues here:
1. When more than 8 bits per sample are used, a previous commit changed
it so that we would be using 16-bit integer mode instead of 8-bit.
However, the actual code for this specific format was not updated to
reflect that.
We fix this by computing 16-bits per channel values and upshifting the
10 and 2-bit samples to 16 bit per channel.
2. The computation of masks was incorrect. It computed each channel
mask separately, based on whether it was <= 8 or not.
However, if any channel needs more than 8 bits, all masks should be
computed 16 bits since we will then 16-bit integer mode.
We fix this by checking all channel bits together, and if any is higher
than 8, but not more than 16, we use 16-bit masks.
I also took this opportunity to add support for 32-bit masks if we
ever need those.
@Wormnest noted remaining regressions after 8faad92e.
The second fread() only runs if the DDSD_PITCH flag is set,
so the error handling check should also be conditional.
Additionally, the ZDI-CAN-22093 exploit no longer runs but
still could cause a plug-in crash. This patch adds an additional
check to ensure the buffer size was within bounds.
@Wormnest pointed out that compressed files are likely smaller than
width * height * bps, so our check to prevent ZDI-CAN-22093
also caught valid files.
The size check is removed from load_image () and moved to load_layer ()
before the two fread() functions, as we know exactly how much we'll
try to read at that point.
...by adding parameters and porting to
GimpProcedureConfig/GimpProcedureDialog.
Code was also rearranged to match the ordering
of other plug-ins.
As a note, the help message is "Special effects that nobody understands".
It would be nice if someone with more familiarity with this plug-in could
update the help messages to explain the parameters.
Note that "save-type" and "mipmaps" were left as ints rather than GimpChoice,
as some options are conditionally disabled and I don't know if that
is available in GimpChoice just yet.
A DDS loading bug related to 6ad54ca3 was also resolved.
The correct header value to check for the pixel size was not "depth" but "bpp".
I also remove (without replacement) 2 usages of gimp_get_data() without
associated gimp_set_data(). According to the comment, it looks like the
associated data was likely set by the GAP plug-in instead. Let's drop this.
Finally I see a lot of arguments, several of them being float arrays, so I
wondered if they were related to the curve and point arrays we are storing as
aux arg now. Apparently these arguments are not even used in the plug-in, right
now, which is explained in commit e318651c99. Maybe if these were actually
used/set and if we implement float array (de)serialization, would this aux
argument become useless?
Lastly, I deleted some code paths which were never used. For instance, stored
bval.total_steps was never set to anything else than 0 anywhere (so I removed
both the variable and the other code-path, which actually ended up being the
GAP-related data get). Additionally in p_bender_calculate_iter_curve(), there
was a big else block which was only happening when the GAP-related variables
were set. It got deleted too (as is a function only used in this block of code).
The argument is the serialized description of the generated fractal. Actually it
may even be useful as a non-aux argument. A GFile argument could eventually be
interesting too, though one arg per setting would be better of course (it allows
more easily to generate animated frames for instance). In such a case, the GFile
would be used in priority, otherwise the other args.
Notes:
* I didn't port to GimpProcedureDialog though it looks like it would not be too
hard (most of the GUI would still be custom GTK code, yet we could have the
generic "reset to initial|factory values" buttons and load/save).
* The custom "Reset" button (identical to what "reset to factory values" would
do) works fine anyway.
* The "run with last vals" works fine where there were indeed previous runs
(which may be in previous sessions), but crashes when it's actually the first
run ever. Some of the base structure data were not initialized. It should not
be too hard yet would require a bit of code reorganization to fix this.
- Argument "parameter-uri" becomes "parameter-file" (GFile instead of URI
string).
- Adding a "settings-data" auxiliary bytes argument to handle all settings for
the time being, instead of using gimp_get_data() and gimp_set_data().
- "last_file_name" was also removed from the ValueType struct, using the
"settings-data" arg instead.
- Fixing the non-interactive usage which was missing a gegl_init() call.
- Use GIO for various reading and writing to a CML parameter file.
- Better bubbling up of error messages.
- Fix the loading of the last section of CML parameters file.
- Also fixing deactived file dialog when clicking the open button a second time.
We use a GBytes auxiliary argument (i.e. not visible in the public API) which
perfectly replace gimp_[gs]et_data() API, in even better (since it also works
across sessions).
The "Reset to initial values|factory defaults" still don't work. We could make
these work even with the AUX args, but I feel like this would be far too much
work for a non-optimal solution anyway. The real solution can be when we get
more public arguments to this PDB procedure to handle every setting
individually. This can happen after GIMP 3 release (especially now that
arguments number and order don't break the PDB API anymore).
I added a bunch of arguments, in particular nearly all the settings in the main
dialog, except for "Colormap" as I'm unsure yet how to handle it. It looks like
a mix of GimpChoice and GimpDrawable. I guess it could just be both (2 args,
using values from the GimpChoice if GimpDrawable arg is NULL).
And I didn't make the settings in the "Edit Flame" dialog into arguments as I'm
not sure if the "Speed" and "Variation" in particular should be args, or are
just temporary args only meant to construct a flame (in particular, it looks
like it builds data defining the flame?). These data should be their own args
probably?
Maybe we could also have the "file" as alternative way to init the flame data
(the "Open" button)?
For now, I'm just storing the whole settings struct as an aux argument, so that
"Load/Save Settings" work, as well as the initial values from previous run.
Also the whole code is still a bit of a mess. I feel like we could really
simplify a lot of the code, all these values stored globally or duplicated now
in both the GimpProcedureConfig and the control_point structure.
I added a few specific validations for range types (int, double…), and a
generic validation at the end, meant to catch all yet uncaught invalid
argument cases (yet with less details on the what and why).
These are stored in the Extended Block. This block also holds metadata
in Exif, IPTC, and XMP formats, but those are not yet implemented in this
patch. A comment stating Exif was implemented in PSP 10 was corrected
to PSP 8 as well.
Changes only to ScriptFu.
The third term (the default) of a SF-FONT etc. spec is now ignored.
Test case is SF>Test>Sphere. There are still crashing issues
related but separate.
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.
The gimp_procedure_run() already existed, though it was with an ordered
GimpValueArray array of arguments. Its usage feels redundant to the series of
gimp_pdb_run_procedure*() functions (which is confusing), but
gimp_procedure_run() was actually a bit more generic, because it does not
necessarily calls GimpProcedure-s through the PDB! For instance, it can runs a
local GimpProcedure, such as the case of one procedure which would want to call
another procedure in the same plug-in, but without having to go through PDB. Of
course, for local code, you may as well run relevant functions directly, yet it
makes sense that if one of the redundant-looking function is removed, it should
be the more specific one. Also gimp_procedure_run() feels a lot simpler and
logical, API wise.
A main difference in usage is that now, plug-in developers have to first
explicitly look up the GimpPdbProcedure with gimp_pdb_lookup_procedure() when
they wish to call PDB procedures on the wire. This was done anyway in the
gimp_pdb_run_procedure*() code, now it's explicit (rather than calling by name
directly).
Concretely:
* gimp_pdb_run_procedure(), gimp_pdb_run_procedure_config() and
gimp_pdb_run_procedure_valist() are removed.
* gimp_procedure_run() API is modified to use a variable args list instead of a
GimpValueArray.
* gimp_procedure_run_config() and gimp_procedure_run_valist() are added.
* gimp_procedure_run_config() in particular will be the one used in bindings
which don't have variable args support through a (rename-to
gimp_procedure_run) annotation.
Passing (name, type, value) triplets is actually useless because we can get the
type information from the procedure/config anyway. That only adds one more
verification to do. Let's just change the function so that we pass (name, value)
couples instead, pretty much like in `g_object_set()`.
As far as plug-in API is concerned, at least the calling API, order of arguments
when calling PDB procedures doesn't matter anymore.
Order still matters for creating procedures with standard arguments (for
instance, "run-mode" is first, then image, or file, drawables or whatnot,
depending on the subtype of procedure), but not for calling with libgimp.
Concretely in this commit:
- gimp_pdb_run_procedure_argv() was removed as it's intrinsically order-based.
- gimp_pdb_run_procedure() and gimp_pdb_run_procedure_valist() stay but their
semantic changes. Instead of an ordered list of (type, value) couple, it's now
an unordered list of (name, type, value) triplets. This way, you can also
ignore as many args as you want if you intend to keep them default. For
instance, say you have a procedure with 20 args and you only want to change
the last one and keep the 19 first with default values: while you used to have
to write down all 20 args annoyingly, now you can just list the only arg you
care about.
There are 2 important consequences here:
1. Calling PDB procedures becomes much more semantic, which means scripts with
PDB calls are simpler (smaller list of arguments) and easier to read (when
you had 5 int arguments in a row, you couldn't know what they refer to,
except by always checking the PDB source; now you'll have associated names,
such as "width", "height" and so on) hence maintain.
2. We will have the ability to add arguments and even order the new arguments in
middle of existing arguments without breaking compatibility. The only thing
which will matter will be that default values of new arguments will have to
behave like when the arg didn't exist. This way, existing scripts will not be
broken. This will avoid us having to always create variants of PDB procedure
(like original "file-bla-save", then variant "file-bla-save-2" and so on)
each time we add arguments.
Note: gimp_pdb_run_procedure_array() was not removed yet because it's currently
used by the PDB. To be followed.
Similar to commit 6905b0bbef for "file-pat-save-internal". For interactive
usage, nothing is changed, but for non-interactive ones, we can now choose a
list of drawables to export.
Pending more changes, relative to the discussion in #7370.
This goes with our planned change of not making GimpProcedure arguments order
relevant anymore regarding the PDB API. In particular, it means we don't want to
use GimpValueArray for various procedure arguments API, but directly
GimpProcedureConfig objects.
This change will allow to add or reorder arguments in the future, so that we
won't have to create new PDB procedures when adding new arguments, while still
keeping PDB API stability.
Add Border enlarges an image by twice the specified border size and creates the border in this
additional space. If an image already has the intended final size, this behaviour is not desired.
This change adds a toggle to (dis)allow resizing, similar to the drop shadow script.

Adds code to read in PSP_SELECTION_BLOCK.
If there was an active selection in the PSP file when it was
saved, that selection will now be active in GIMP as well on load.
Improper counting of args declared by scripts versus pspecs in a ProcedureConfig.
Scripts don't declare run_mode, while pspecs have run_mode and an extra internal pspec
that is not an argument.
