If CAP_CAMERSIDE is TWCS_BOTH, then Get message will return data from front side and
set/reset message will change both sides. This is default scanner behavior.
3.12 S
CANNING MODES
These scanner modes are related to TWAIN DS API only.
3.12.1 Simple mode
Most of TWAIN application used this mode. User can scan Simplex/Duplex and it is possible to
specify few frames (all with same image settings except the frame size and location), but it is not
possible to obtain multistream from the scanner.
3.12.2 Multistream using standard TWAIN interface
It is based on CAP_CAMERAENABLED capability introduced in TWAIN version 2.0. Using
CAP_CAMERASIDE, ICAP_PIXELTYPE and CAP_CAMERAENABLED, an application can
specify several PixelTypes per side. If TWAIN DS finds that application enable more than one
camera it discard CAP_DUPLEX capability and it will use CAP_CAMERAENABLED instead of it
to determine if it must scan Simplex or Duplex. Application can use this mode to scan back side only
Here is an example:
Set CAP_CAMERASIDE to TWCS_TOP
Set ICAP_PIXELTYPE to TWPT_BW
Set CAP_CAMERAENABLED to TRUE
Set ICAP_PIXELTYPE to TWPT_RGB
Set CAP_CAMERAENABLED to TRUE
Set CAP_CAMERASIDE to TWCS_BOTTOM
Set ICAP_PIXELTYPE to TWPT_BW
Set CAP_CAMERAENABLED to TRUE
Scan
TWAIN DS will return Black and White (Bitonal) and Color image from front side and Black and
White (Bitonal) image from back side.
3.12.3 Custom Multistream mode
This mode is based on custom capabilities and can be used only from applications specially written
for this TWAIN DS. This completely corresponds to scanner windows system.
