Hi all,
I am trying to change a colour to transparent by doing this:
(gdk-pixbuf-add-alpha img #t (integer->char r) (integer->char g)
(integer->char b))
(Doing `interger->char' seems a bit weird but passing ints causes
errors.)
However, the image is not changed (I write it out using
gdk-pixbuf-save-to-port).
Doing it on the command line works fine:
convert old.png -transparent 'rgb(R,G,B)' new.png
so I am pretty sure there is no problem/misunderstanding regarding the
file and the colours.
Anybody have any ideas how to do this in Guile?
