Hi David,

Envision does not support ISIS scanning. The last time I checked ISIS scanning required paying royalties, and now most twain drivers can scan at fast speeds.

Envision is limited in what you can do while ShowUI = False. Some drivers will simply ignore the request. Since all drivers are not created equal, I usually recommend using the interface of the scanner, which should make all options available.

Envision will only allow you to set the resolution and image format with ShowUI=False, and that is only if the driver supports it.

Best regards,
