Description Andreas Betz 2011-09-15 12:34:47 UTC 
Regarding the OpenVG 1.1 spec vgChildImage should be used if you have an image and a sub image of it and you still need both...

vgChildImage should use the original images data to avoid copying the part of the image ... and so on ... like vgImageSubData + vgCreateImage does.

Unfortunately vgChildImage returns VG_INVALID_HANDLE each time i call it.

So my question is there a chance that this is ging to be supported?

It was broken by a fix for 64-bit system (commit 99c67f27d35a).  vg_context_is_object_valid never returns true for VGImage and other objects.  I will work on a fix next week.

This should be fixed by ceb6d349 on master.
