31 Capabilities
32 ------------
33 Every Source must support all five DG_CONTROL / DAT_CAPABILITY operations on:
34 CAP_XFERCOUNT
35 Every Source must support DG_CONTROL / DAT_CAPABILITY MSG_GET on:
36 CAP_SUPPORTEDCAPS
37 CAP_UICONTROLLABLE
38 Sources that supply image information must support DG_CONTROL / DAT_CAPABILITY /
39 MSG_GET, MSG_GETCURRENT, MSG_GETDEFAULT on:
40 ICAP_COMPRESSION
41 ICAP_PLANARCHUNKY
42 ICAP_PHYSICALHEIGHT
43 ICAP_PHYSICALWIDTH
44 ICAP_PIXELFLAVOR
45 Sources that supply image information must support DG_CONTROL / DAT_CAPABILITY /
46 MSG_GET, MSG_GETCURRENT, MSG_GETDEFAULT, MSG_RESET and MSG_SET on:
47 ICAP_BITDEPTH
48 ICAP_BITORDER
49 ICAP_PIXELTYPE
50 ICAP_UNITS
51 ICAP_XFERMECH
52 ICAP_XRESOLUTION
53 ICAP_YRESOLUTION
54 All Sources must implement the advertised features supported by their devices. They must
55 make these features available to applications via the TWAIN protocol. For example, a Source
56 thats connected to a device that has an ADF must support DG_CONTROL /
57 DAT_CAPABILITY / MSG_GET, MSG_GETCURRENT, MSG_GETDEFAULT on:
58 CAP_FEEDERENABLED
59 CAP_FEEDERLOADED
60 and DG_CONTROL / DAT_CAPABILITY / MSG_GET, MSG_GETCURRENT,
61 MSG_GETDEFAULT, MSG_RESET and MSG_SET on:
62 CAP_AUTOFEED
63 If the ADF also supports ejecting and rewinding of pages then the Source should also support
64 DG_CONTROL / DAT_CAPABILITY / MSG_GET, MSG_GETCURRENT,
65 MSG_GETDEFAULT, MSG_RESET and MSG_SET on:
66 CAP_CLEARPAGE
67 CAP_REWINDPAGE
