Paper size issue with scanner application

[VBCoder68]

I'm using the GD Picture Pro 5 product to create an app to let the user scan images into a database. I'm very new to the product. Can someone tell me how to display the scanner properties to the user? I'm having an issue where the scanner is using the wrong paper size by default and I want the user to be able to select it before he runs the scan.

Thanks in advance.

Hi,

To get information about available features of a TWAIN device you can use method TwainIs[FEATURE]Available.

IE for automatic plank page discard:

Code: Select all

Dim bAvailable as Boolean = Object.TwainIsAutomaticDeskewAvailable()

For your paper size issue, you should have a look on following methods:

TwainGetAvailablePaperSizeCount -> Returns the number of supported page size of the TWAIN device
TwainGetAvailablePaperSizeNo -> Returns a supported page size
TwainSetPaperSize -> Select a std page size. (should be a value returned by the TwainGetAvailablePaperSizeNo method).

Hope this helps !
