What does the 'TwainItemTypes' mean ?
Dear all,
Would appreciate that if you could tell what does each of the enum in 'TwainItemTypes' mean.
When I run the code below, it returns me the TWTY_BOOL''.
Dim type As TwainItemTypes = oGdPictureImaging.TwainGetCapItemType(TwainCapabilities.CAP_UICONTROLLABLE)
Best Regards,
Jun Wei

Re: Why there is no image compression for GIF, JPEG, PNG image
Hi Gabriela,
This is the behavior of our application.
We will show the compression method when users click on picture.
Is it really no way to show this ?
