Twain Transfer Modes

Post by dtheiss » Thu Nov 24, 2016 3:17 pm

Hello,

Twain 2.3 supported following transfer modes: native, disk file, buffered memory.
Are these the mapped methods in GdPicture?
  • native: TwainAcquireToDib
  • disk file: TwainAcquireToFile
  • buffered memory: TwainAcquireToGdPictureImage
Regards,

Hi,

Not exactly:

- native: TwainAcquireToDib() or TwainAcquireToGdPictureImage() with TwainEnableMemoryTransferMode(false)
- disk file: TwainAcquireToFile()
- buffered memory: TwainAcquireToDib() or TwainAcquireToGdPictureImage() with TwainEnableMemoryTransferMode(true)

Please let me know if you need further information.

With best regards,

Loïc
