Change EGLSurface Size/Resolution

Other Parts Discussed in Thread: OMAP3530

Hi,

I am using OpenVG under Linux on the OMAP3530 to create graphics. My problem is that when I change the frame buffer size and DSS output timings, the graphics application doesn't recognise the change.

Currently, what I have to do is destroy the EGLSurface and EGLContext within in the application, restart the pvrsrvkm module and then recreate a new EGLContext and EGLSurface. This means that any colours, paths, and images are destroyed and must be recreated on a change of resolution, which really isn't ideal. Is there a better way of doing this?

I notice on Nokia's Symbian platform, the eglSwapBuffers function recognises the change of resolution and adjusts the EGLSurface size accordingly. Is this not possible on the OMAP3530?

Thanks,

 

Andy
