[OMAP3530] Maximun number of segments in OpenVG path

Other Parts Discussed in Thread: OMAP3530

Hello, does anyone knows what is the maximum number of segments can added to OpenVG path.

I'm trying to use OMAP3530 openVG implementation and get very erratic behavior from OpenVG library once i get more than 1600-1700 elements inside path.

It does not report any error, all API calls finish sucessfuly, but when trying to draw application crashes somewhere inside libOpenVG

Is there better place to post problems with OpenVG implementations ? I have couple of other problems to report.

      The PowerVR documentation advises against using long paths.  This is because the paths must be tessellated into triangle lists to be rendered by the SGX and the tessellation becomes more difficult the longer the paths are.  The maximum length would depend on how much the paths cross themselves because that increases the triangle count also.
