Add flag GIMP_METADATA_SAVE_COLOR_PROFILE to GimpMetadataSaveFlags and
initialize it from gimp_export_color_profile() in
gimp_image_metadata_save_prepare().
Adapt all plug-ins to use the bit from the suggested export flags and
pass the actually used value back to
gimp_image_metadata_save_finish().
This changes no behavior at all but creates hooks on the libgimp side
that are called with the context of an image before and after the
actual export, which might become useful later. Also, consistency
is good even though the color profile is not strictly "metadata".
Some refactoring: add gimp_metadata_get,set_colorspace() and a new
enum GimpMetadataColorspace which so far can be one of { UNSPECIFIED,
UNCALIBRATED, SRGB, ADOBERGB }. The setter is untested and I don't
know if it's doing the right thing, please review. Use the getter in
gimp_image_metadata_load_finish(), so complex metadata logic and
profile creation/setting are separated.
Add flag GIMP_METADATA_LOAD_COLORSPACE which defaults to TRUE, and in
gimp_image_metadata_load_finish(), assign AdobeRGB to the image if
Exif.Iop.InteroperabilityIndex says "R03". This is most likely very
incomplete because there are quite some other colorspace tags in
various parts of the image metadata.
start with flags = ALL (which now includes all possible current and
future flags), and optionally *remove* individual flags instead of
adding them. This way the plug-ins default to TRUE for future flags.
So the plug-in has the chance to decide whether it wants to trust the
metadata information (e.g. resolution). Also reorder parameters in
gimp_image_metadata_save_finish(). Change all plug-ins accordingly.
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
