Hi Leonel, I'm not exactly sure what you're asking here. Are you just
trying to determine the width and height of an image stored in the png
format? I suppose that you can load an image surface with a call to
cairo_image_surface_create_from_png, then get the width and height via
cairo_image_surface_get_width and cairo_image_surface_get_height.
Although, if that's all you need, cairo really is overkill. There are
more lightweight ways of doing this.

Hope that helps,

Dan
