As mentioned in issue #1777, exporting non-animated WebP images was
only keeping the current layer.
Mimick file-gif-save.c: display the encoding settings pop-up earlier
so that gimp_export_image() can merge the layers unless "As Animation"
is enabled. Call gimp_image_get_layers() directly in save_image() in
case the layers were merged (for clarity because layers are used only
for animations).
(cherry picked from commit 8f828d1899)
Various plug-ins exporting metadata should now follow preferences, which
would override any default. Of course these preferences can still be
overriden by saved settings (global parasite), previous run settings,
and finally through the GUI when interactive.
webp-save: Add UI elements for 'minimize size' toggle, and a dependent
'max key-frame distance' setting.
* If 'minimize size' is active, max-kf is disabled (which is equivalent to
setting it to infinity). Key-frame cost file size, that's why.
* If 'minimize size' is disabled, you get to choose how far key-frames
(=cue points) will be inserted at max.
...in the export dialog
- change the *preset field to a proper enum
- clean-up some code related to preset
- change the UI dialogs to use a GimpIntComboBox
- misc style fixes
- quite modified by mitch to be much less code
- get_preset_from_id() was defined in file-webp-dialog.c but used in
file-webp.c only. Move it there.
- Make the preset list available in file-webp-save.h header (since it
is specifically an encoder attribute) as static, because it is used
both in the dialog ("preset" choice list) and the main file (for match
of the "preset" parameter as internal ID to a WebPPreset when run as
non-interactive).
- Generate the "preset" parameter description from the preset list.
This way, even if this list were to change (in some hypothetical
future), the description (and in particular the list of possible
values and their int match) won't end up wrong.
- "enum WebPPreset" is typedef-ed to "WebPPreset".
- Use G_N_ELEMENTS to compute length of arrays on the stack (equivalent
to the current code but shorter and simpler to read).
- Many formatting fixes.
- change the *preset field to a proper enum
- clean-up some code related to preset
- change the UI dialogs to use a GimpIntComboBox.
- misc style fixes
animated webp saving: parse time-stamp from layer_name (instead of using
default value of '100')
also:
- add a default delay field to UI, in case time-stamps are not present.
- add a 'force delay' checkbox
- revamp the whole UI to look like the GIF saving UI.
This adds an expander to the webp file plug-in to select whether
to save or not the exif, and xmp data for webp files. This harmonizes
the plug-in with a similar option to the jpg/png file plug-ins.
