Hello,
this is my first post ever on a mailing-list, I hope I'm doing it the
right way. My apologies if not so.
I'd like to draw text on a pixbuf. I first tried :
- to write text in a PangoLayout
- to render the layout in a pixmap
- to copy the pixmap in the pixbuf
It worked, but the text has a black background that overlap the
previously drawn things on the pixbuf. And I can't change the background
color (with a gdk_gc_set_background for example).
So, I tried :
- to render the pixmap in a temporary pixbuf
- to add alpha to this pixbuf, making black become transparent
- to copy this temporary pixbuf in my final pixbuf.
Same results. And I don't know why.
Maybe alpha isn't taken into account by gdk_pixbuf_copy_area ? If so, I
suppose it's not too hard to make another version of this primitive
doing that (but slow).
And since it bothers me to have black as background color (what will I
do if the foreground color is also black ? It may happen with text), do
you have an idea for how to change the background color ?
Thanks in advance. And excuse my english, school is far away now...
Fred
