Re: [Gimp-developer] Of Palettes and Plug-ins

["Joao S. O. Bueno" <gwidion mpc com br>]

Besides  - you have to check what makes more sense - I't think Palette
exporting/importing plug-ins have to be on the Palletes context menu

My basic design is going to be as follows:

   - Add a procedure to register a palette loader

There is no such thing as a "palette loader" - but there are plug-ins that
are registered under thhe "Palette" context menu. Ther is a sub-menu
named "Export as..." -
I think a loader should be under <palette>/Import/<title>"

   This procedure will check that registered procedure take an int32 and
   two strings and return a palette. The args are the same as those for the
   image importer, and the return is a palette instead of an image.
If it is a Python script, maybe you  prefer using "PF_FILE" instead
of a string - that allows you to programatically pass a  file path,
but the automatic
Python-fu interface would open a nice file dialog to use your plug-in directly.

   - Write a python (or other language) procedure to implement that
   interface.
Python recomended - some of the options in the Pallete context menu
are already in Python, copy one of them and it will be easier for you
to make your own.

And finally -as noted in the other e-mail I sent: the returend
"PF_PALETTE" is a string, but
a string corresponding to a unique name palette in GIMP, which is used
as ID for all Palette related
PDB calls.
