...won't work with older GIMP?
Make gimp_image_get_xcf_version() return a "reason" string which lists
all reasons why the image can't be saved with compatibility for older
GIMP versions. Display the reason as tooltip on the compat hint label
in the save dialog.
Both in the GimpImage API and in the GUI. The toggle in the save
dialog now controls ZLIB compression directly. Changed the various
info labels accordingly. Ditch the XCF parasite that saved the XCF
compat mode.
Nobody has them anymore, and they are deprecated in GTK+ 3.x. This
also fixes all conflicting mnemonics except those I missed, but we can
fix them now.
Change GimpFileDialog's file-procs properties to enum
GimpFileProcedureGroup and get them via the newly added API. Set
properties common to all dialogs in the parent class.
file-procedure.[ch] is gone and its functions moved to
GimpPlugInManager where they belong (the manager keeps around the
lists of load, save and export procedures).
Utility functions from file-utils.[ch] that have nothing to do with
image files moved to core/gimp-utils.[ch].
Metadata presence implies XCF version 6 or higher. Yet metadata are
stored in parasites which are perfecly supported in older GIMP versions
and are passed along through saving.
Therefore there is no need to keep XCF 6. We just add a warning telling
that metadata won't be visible in older GIMP when saving a file with
metadata and compatibility mode.
By default, it only saves the current file filter, but it allows a child
to implement its own state. It has been implemented by GimpSaveDialog to
save the preferred compatibility mode as well.
The code refactoring allows better readability which will allow in turn
to add more complex specific features making good use of the save/export
split concept.
