Help with vgImageGetDirectVIV()

[tmeyer]

Hi,

I would like to understand what and how these functions work:

vgImageGetDirectVIV()

vgImageFlushDirectVIV()

found in the openvg.h OpenVG 1.1 API

Ultimately, I wand direct access to the memory where a vgImage is stored. I managed to get this somewhat working using these functions, however I would like to understand what exactly these function do so that I can use them properly. Does anyone know? or is there any documentation/code comments describing them or there usage?

Thanks,

Hi Tim,

Did you find how to use those functions, I also could not found any reference to it in documentation, nor any sample code that make use of them.
