[Gtk-sharp-list] Gdk.Pixbuf.RenderPixmapAndMask question

[Mariano Benedettini]

Hello Dan,

Can you point me in the direction of a solution for this problem?:

...
Gdk.Pixmap pixmapOut, pixmapOutMask;
...
myPixbuf.RenderPixmapAndMask(out pixmapOut, out pixmapOutMask, 255);
image3.SetFromPixmap(pixmapOut, pixmapOutMask);


test1.cs(92,6): error CS1502: The best overloaded method match for 
`Gtk.Image.SetFromPixmap(Gdk.Pixmap, Gdk.Bitmap)' has some invalid arguments
test1.cs(92,6): error CS1503: Argument 2: Cannot convert from 
`Gdk.Pixmap' to `Gdk.Bitmap'
Compilation failed: 2 error(s), 0 warnings


Thanks,
Mariano.
