OpenVG example program gives distorted screen

sidebranch — Sun, 22 Jan 2012 11:27:49 GMT

Has anyone tried building the OpenVG example program which can be found here?

http://imxdev.org/wiki/index.php?title=Develop_a_simple_OpenVG_application_under_Linux_tutorial

The results for me is a distorted screen (lots of noise), with a small image (upside down!).

Have you tried the other OpenVG samples in the GPU SDK (like the SVG tiger)? Do any other apps give you a distorted screen? This may be a display setup issue.

After reading your reply I concluded that the GPU SDK you mention is not the same as the amd-gpu-bin-11.09.01-201112.tar.gz archive. (This is the non-X11 variant).

The problem with all the examples in the non-X11 tar archive (amd-gpu-bin) in that they depend on X11 libraries. So I cannot use them in my setup.

I will however find the GPU SDK and experiment with it.

Thanks, Leon.

You can get the GPU SDK (which is mostly code samples, etc.) at freescale.com. Just put "GPU SDK" in the search box.
