Requirements to be a TWAIN-Compliant Source
|
|
Requirements
|
|
TWAIN-compliant Sources must support the following:
|
|
Operations
|
|
----------
|
|
DG_CONTROL / DAT_CAPABILITY / MSG_GET
|
|
DG_CONTROL / DAT_CAPABILITY / MSG_GETCURRENT
|
|
DG_CONTROL / DAT_CAPABILITY / MSG_GETDEFAULT
|
|
DG_CONTROL / DAT_CAPABILITY / MSG_RESET
|
|
DG_CONTROL / DAT_CAPABILITY / MSG_SET
|
|
DG_CONTROL / DAT_EVENT / MSG_PROCESSEVENT
|
|
DG_CONTROL / DAT_IDENTITY / MSG_GET
|
|
DG_CONTROL / DAT_IDENTITY / MSG_OPENDS
|
|
DG_CONTROL / DAT_IDENTITY / MSG_CLOSEDS
|
|
DG_CONTROL / DAT_PENDINGXFERS / MSG_ENDXFER
|
|
DG_CONTROL / DAT_PENDINGXFERS / MSG_GET
|
|
DG_CONTROL / DAT_PENDINGXFERS / MSG_RESET
|
|
DG_CONTROL / DAT_SETUPMEMXFER / MSG_GET
|
|
DG_CONTROL / DAT_STATUS / MSG_GET
|
|
DG_CONTROL / DAT_USERINTERFACE / MSG_DISABLEDS
|
|
DG_CONTROL / DAT_USERINTERFACE / MSG_ENABLEDS
|
|
DG_CONTROL / DAT_XFERGROUP / MSG_GET
|
|
DG_IMAGE / DAT_IMAGEINFO / MSG_GET
|
|
DG_IMAGE / DAT_IMAGELAYOUT / MSG_GET
|
|
DG_IMAGE / DAT_IMAGELAYOUT / MSG_GETDEFAULT
|
|
DG_IMAGE / DAT_IMAGELAYOUT / MSG_RESET
|
|
DG_IMAGE / DAT_IMAGELAYOUT / MSG_SET
|
|
DG_IMAGE / DAT_IMAGEMEMXFER / MSG_GET
|
|
DG_IMAGE / DAT_IMAGENATIVEXFER / MSG_GET
|
|
|
|
Capabilities
|
|
------------
|
|
Every Source must support all five DG_CONTROL / DAT_CAPABILITY operations on:
|
|
CAP_XFERCOUNT
|
|
Every Source must support DG_CONTROL / DAT_CAPABILITY MSG_GET on:
|
|
CAP_SUPPORTEDCAPS
|
|
CAP_UICONTROLLABLE
|
|
Sources that supply image information must support DG_CONTROL / DAT_CAPABILITY /
|
|
MSG_GET, MSG_GETCURRENT, MSG_GETDEFAULT on:
|
|
ICAP_COMPRESSION
|
|
ICAP_PLANARCHUNKY
|
|
ICAP_PHYSICALHEIGHT
|
|
ICAP_PHYSICALWIDTH
|
|
ICAP_PIXELFLAVOR
|
|
Sources that supply image information must support DG_CONTROL / DAT_CAPABILITY /
|
|
MSG_GET, MSG_GETCURRENT, MSG_GETDEFAULT, MSG_RESET and MSG_SET on:
|
|
ICAP_BITDEPTH
|
|
ICAP_BITORDER
|
|
ICAP_PIXELTYPE
|
|
ICAP_UNITS
|
|
ICAP_XFERMECH
|
|
ICAP_XRESOLUTION
|
|
ICAP_YRESOLUTION
|
|
All Sources must implement the advertised features supported by their devices. They must
|
|
make these features available to applications via the TWAIN protocol. For example, a Source
|
|
thats connected to a device that has an ADF must support DG_CONTROL /
|
|
DAT_CAPABILITY / MSG_GET, MSG_GETCURRENT, MSG_GETDEFAULT on:
|
|
CAP_FEEDERENABLED
|
|
CAP_FEEDERLOADED
|
|
and DG_CONTROL / DAT_CAPABILITY / MSG_GET, MSG_GETCURRENT,
|
|
MSG_GETDEFAULT, MSG_RESET and MSG_SET on:
|
|
CAP_AUTOFEED
|
|
If the ADF also supports ejecting and rewinding of pages then the Source should also support
|
|
DG_CONTROL / DAT_CAPABILITY / MSG_GET, MSG_GETCURRENT,
|
|
MSG_GETDEFAULT, MSG_RESET and MSG_SET on:
|
|
CAP_CLEARPAGE
|
|
CAP_REWINDPAGE
|
|
