Our metadata library exiv2 only registers the most commonly used xmp
namespaces. Other namespaces need to be explicitly registered. We did not
read or try to store these namespaces, which caused a lot of warnings about
"No namespace info available for XMP prefix '...' and then we could not
process that metadata or save/export those tags.
We had to wait for gexiv2 support for registering/reading namespaces, but
that was added in gexiv2 version 0.12.2 (and the "try" version in 0.14.0).
When reading xmp metadata we process all namespaces and add them to our
metadata xml when we haven't seen them before in the same image.
A GHashTable is used to keep track of the prefixes we have seen before.
The new namespace xml tag is skipped in older GIMP versions, but will be
used now to add the namespaces when exporting images with xmp metadata.
TIFFs with PSD layers can be saved in either Macintosh or IBM PC format.
IBM PC section labels are reversed and the integers are Little Endian.
We now check for 'MIB8' sections and reverse the necessary values so
that the PSD plug-in functions can handle them.
In !769, I accidentally removed the ability to paste into an empty
workspace with Ctrl+V since I added a "does image exist?" check before
the `edit_paste_as_new_image_cmd_callback ()` call.
This patch resolves the issue by moving the check after the
"paste as image" function call.
"Hold and Modify" ILBM images use control bits to increase the palette
beyond what's stored in the CMAP chunk. This patch checks if
HAM mode is set and then interprets the plane bits accordingly.
This commit converts `GimpModuleDB` into a `GListModel`. This allows us
to drop quite a bit of custom code to have an adaptive list of modules
by just becoming a `GListModel` implementation.
Next to that, this commit also rewrites `GimpModule` to use the `notify`
signal for its 2 new properties: "auto-load" and "on-disk", rather than
trying to define a custom signal for that. This in turn allows us to use
basic methods like `g_object_bind_property()`.
Finally, the module manager dialog now uses `GtkListBox`, which can
easily bind to that new `GListModel` infrastructure.
Use a `GtkListBox` to show the list of GIMP themes rather than a
treeview. The idea is that we can expand this a bit more to give a
preview of the theme later on.
In case someone passes a `GtkWidget` rather than a `GtkWindow` as a
parent to a `GimpDialog`, we still have another way of trying to get its
parent window, using `gtk_window_get_toplevel()`. If we still get a
window from that, it allows us to still specify a reasonable
"transient-for" value for our newly-made `GimpDialog`.
