CL_Rx (image_channel_order)

Hello

I have a problem with using the image_channel_order CL_Rx. I need the format to avoid border color problems in image processing. I tried CL_Rx on my Quadro 600, GTX 285 and GTX 480 with different driver versions but on all cards the format is not supported. It seems that CL_Rx is not available on NVIDIA cards up to now.

Does anybody tried the image channel order CL_Rx, CL_RGx or CL_RGBx?

Best regards

Steffen
