Canon DR-9080 series does not support Twain AutoSize capability (ICAP_AUTOSIZE). The reason: ICAP_AUTOSIZE came with TWAIN2.0 specs and the driver of the 9080 has been built on top of the 1.8.
I think this capability can be managed by another non TWAIN compliant value using the TwainSetCapCurrentNumeric method. But unfortunately I don't know the value of this CAP. I think it is one of the following (but not sure) : 0x8100, 0x801D, 0x801E.
The other solution consists to use TwainSetPaperSize & TwainSetImageLayout method like this:
Code: Select all
oGdPictureImaging.TwainSetPaperSize(TwainPaperSize.NONE) oGdPictureImaging.TwainSetImageLayout(0, 0, 29.7 / 2.54, 21 / 2.54)
