Hi Nigel,

i also found the Microsoft Documentation.
But i don't know how to give or set the RGBQuad with WIAParams.SetDeviceProperty(WIA_DPS_PAD_Color, RGBQuad)

Thanks Ralf

Hi Ralf

It will need to be:

WIAParams.SetDevicePropertyVariant(WIA_DPS_PAD_Color, RGBQuad);

But I have not tested this, so ensure the RGBQuad structure aligns with the MS standard.

Hi Nigel,

i tried that way! But the SetDevicePropertyVariant didn't except the RGBQuad as Variant.

Best Regards
Ralf
