Hello all, I'm new to gtkmm. I have some 8-bit grayscale images that I want to display in a gtkmm application. I want to display them as a sequence of frames as an animation like a movie playback. And I will also add some texts on top of the animation. Does anybody have any good idea how to do it properly with performance (speed)? Shall I use the gnome canvas widget? I tested that I could use a look up table and duplicate my 8-bit data for each of the RGB channel and create a RGB pixbuf. But is it possible that I use the grayscale visual and display just my 8-bit grayscale images on the canvas instead of using RGB? Thank you in advance for any help and suggestion.
