Using GdkPixbuf buffers with GraphicsMagick

[Luka Napotnik <luka napotnik gmail com>]

Hello.

I'm trying to use GraphicsMagic (the successor of ImageMagick) to
manipulate a GdkPixbuf image buffer. The problem is that the program
segfaults, probably due to the raw nature of the buffer which the Magick
API doesn't handle very good.
I'm opening the image buffer with MagickReadImageBlob() and then apply
some filters.

Does anyone have experiences using GdkPixbuf together with
GraphicsMagick or can anyone suggest alternatives to GraphicsMagick
which works well with GdkPixbuf?

Greets,
Luka
