Another reply to myself. OK I've looked through the code in gdk-pixbuf and
writing an image importer using gdk-pixbuf along the lines of Hub's jpeg
importer will be quite straight forward. gdk-pixbuf has nice convience
functions to automatically detect the image type in a file and load it
into a GdkPixbuf structure. Once in said structure it is a simple matter
to export it into our png internal format.
Given this I plan to write a Gnome image loading plugin using
Dom and Hub's code as a template.
It will import all the types handled by gnome and since we already link
gdk-pixbuf for gnome, will add 0 to our loading time.
Cheers
Martin
