Loading an image using GTK on Linux [message #791470]

I'm looking for information on creating a "fast path" for loading PNG images on a Linux/GTK SWT application. We've looked at the source code and believe that SWT on GTK+ decodes PNG images in Java into ImageData then uses that data to create the underlying GTK image object. We'd like to turn that around and let GTK decode the image.

Before we jump in and try this, I'd like to find out if other people have tried something similar, or if there is a reason (other than portability issues) why this is a terrible idea.

Thanks!

This already happen if you call this image constructor: Image(Display, String). See:

Thanks! We'll investigate. We're currently loading images out of a JAR file, but changing that would not be difficult.
