Transparency on a XPM file

[César Leonardo Blum Silveira <cesarbs gmail com>]

Hello all,

I have written and app that loads a XPM image from it's data, that is
in a header, and not form a XPM file (i know it's sort of the same
thing, but I used an specific function to get XPM data,
gdk_pixbuf_new_from_xpm_data () ).

However, the background of the image shows up depending on which theme
the user is using. Is there a way I could apply transparency to that
image? Like getting pixel (0,0) and make all pixels with that color be
transparent?

Thanks,
