Hi,

I develop on vc# with leadtools 15. I try to use the twain, but when i use the function to set the image's frame size, it return always an error: Required capability not supported, but scanner support that function.

The function that I use are:

TwainSession.ImageFrame,
TwainCapability: ImageFrame, ImageSupportedSize

How can i set the frame?

Thanks,

Davide

To make sure that your scanner supports the
ICAP_SUPPORTEDSIZES capability, please check using the Twacker application from the Twain working group. If you don't have it, you can get it from:
