+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
