<div dir="ltr"><div>Hi,</div><div> </div><div>I'm struggling to get Cairo compiled on an ubuntu PC. Before I spend any more time on the make problems I wanted to ask if it's worth carrying on.</div><div> </div><div>
I have an existing program using an XLIB window and just want to display a PNG image (could be a BMP if that's easier) in the XLIB window. It looks like the Cairo functions make it easy to read a PNG file into a surface and then copy that to a XLib surface (or device - not quite sure about the terminology). </div>
<div> </div><div>Is this feasible or just not the right way to do it. I don;t want to spend another couple of hours getting cairo compiled to only find I can't use it to show an image file.</div><div><br>Many thanks</div>
