With gimp_guide_custom_new(), you can create a custom guide with a different
style on canvas (other pattern/color/width). A custom guide won't be saved
and could be used, for instance, for specific GEGL op guiding.
Add new XCF property FLOAT_OPACITY and always save both the old 8-bit
and the new float opacity of layers and channels. Float opacity is
saved after the 8-bit one so when loading, it overwrites the limited
8-bit value with the proper precision. Do not increase the XCF version
number because old GIMP versions will simply skip the unknown
FLOAT_OPACITY and keep using the 8-bit value.
GIMP's OVERLAY mode was identical to SOFTLIGHT. This commit fixes the
issue and introduces a NEW_OVERLAY mode and enum value.
- change gimp:overlay-mode to be a real (svg-ish) overlay mode
- when compositing, map OVERLAY to gimp:softlight-mode
- when compisiting, map NEW_OVERLAY to gimp:overlay-mode
- bump the XCF version when NEW_OVERLAY is used
- map OVERLAY to SOFTLIGHT when loading and saving XCF
- map OVERLAY to softlight in all PDB setters
- map OVERLAY to softlight when deserializing a GimpContext
- change all paint mode menus to show an entry for NEW_OVERLAY
instead of OVERLAY
- change PSP, PSD and OpenRaster to use NEW_OVERLAY
These changes should (redundantly) make sure that no OVERLAY enum
value is used in the core any longer because it gets mapped to
SOFTLIGHT at all entry points, with the downside of introducing a
setter/getter asymmetry when OVERLAY was set in a PDB api.
Get rid of most seeking by writing the tile offsets to a table in
memory, instead of directly to the file after each tile. Only seek
back after writing all tiles, in order to save the entire table at
once.
Change XCF saving to never seek past the end of the partially written
file. The only places where we still did this was when skipping the
offset tables for layers, channels, levels and tiles.
Now we write an all-zero offset table first, and then only seek around
in areas of the file that already exist. This also simplifies the code
a bit. Changed comments to make it clear what happens.
Don't use xcf_seek_end() because that seems to be broken on certain
file systems / operating systems / FUSE mounts / whatever. Instead,
seek to explicitly calculated file offsets.
Ported Massimo's patch to master and added comments --Mitch
The same commit in gimp-2-8 is a57e49b1bb
Add gimp_image_get_xcf_version() and use it when saving XCFs. The
function also returns GIMP versions in integer (comparable) and string
form to be used by GUI logic that allows to save compatible files.
and g_warning() for programming errors only.
Use g_printerr() for "normal" errors which may happen in a program
lifetime (in particular corrupted XCF file errors are not necessarily
programming errors).
The code was technically correct previously: It wrote the uninitialized
length only as a placeholder to overwrite it later on. Yet it's better
to not confuse tools (or people) analysing the code. Besides that having
0 for the length in the file while the payload is being written may aid
debugging e.g. crashes in that code later on.
Based on original patches from Hartmut Kuhse and modified
by Michael Natterer. Changes include:
- remove libexif dependency and add a hard dependency on gexiv2
- typedef GExiv2Metadata to GimpMetadata to avoid having to
include gexiv2 globally
- add basic GimpMetadata handling functions to libgimpbase
- add image and image file specific metadata functions to libgimp,
including the exif orientation image rotate dialog
- port plug-ins to use the new APIs
- port file-tiff-save's UI to GtkBuilder
- add new plug-in "metadata" to view the image's metadata
- keep metadata around as GimpImage member in the core
- update the image's metadata on image size, resolution and precision
changes
- obsolete the old metadata parasites
- migrate the old parasites to new GimpMetadata object on XCF load
- 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.
Apply and heavily modify patch from remyDev which adds "lock position"
to GimpItem, similar to "lock content". Lock position disables all
sorts of translation and transform, from the GUI and the PDB.
Cleaned up some aspects of the lock content code as well because a
second instance of similar code always shows what went wrong the first
time.
because it would require really evil hacks to honor these properties
in the gegl projection if they were on the mask, and because they
actually belong to the layer.
Introduced two virtual functions to a GimpViewable
'set_expanded' and 'get_expanded'
and a PROP_GROUP_ITEM_FLAGS to load/save the expanded state
of layer_groups and use them.
and get rid of the brainfuck idea that app/ has to use _gimp_unit_foo()
functions, passing a gimp pointer. Instead, simply use the libgimpbase
API all over the place. Should we ever allow more than one gimp instance,
they will simply have to share one unit database.
