I'm not sure that is correct either. I talked a bit on #gtk+ and there doesn't seem to be any connection to pixels at all. You can end up with any size, usually close to what you want, but you never know. I made a small test program and put up some screenshots of how the text rendering looks when I set the size to 20*PANGO_SCALE. http://www.zigo.dhs.org/~dennis/pango-test/ The reason I want to know approx. how high the text is in pixels is because I draw a chess board and want the coordinates to match the square size. And the square size changes when I resize the window, so the coordinate will have to change size as well. The solution I have so far is to have a loop where I set the size, render and then do pango_layout_get_pixel_extents () until the height is not to big. In my test program when I set the height to 20*PANGO_SCALE the logical rect was 36 pixels high. Also notice the big difference in logical rect when I run with GDK_USE_XFT=1. But probably it has chosen another font in this case. It seems the loop (or binary search) is the correct way to get what I need. -- /Dennis _______________________________________________ gtk-list mailing list [EMAIL PROTECTED] http://mail.gnome.org/mailman/listinfo/gtk-list
