- Used by an application to collect log information from the scanner.
- Refer to kdscust.h for details about how to use this call.
- Only MSG_GET is supported.

each button, as well as to indicate which Paper
Source the button will scan from.
- Only MSG_SET is supported.
DAT_PARENT Full support.
- This operation only communicates with the Source Manager.
DAT_PASSTHRU Unsupported
DAT_PENDINGXFERS Full support.
- MSG_STOPFEEDER is a TWAIN 1.9 operation that may be issued in State 6. Use it when you want to stop the transport, but continue transferring any images that are in the device's buffers.

- These messages are supported for DAT_PROFILES: MSG_GET, MSG_GETCURRENT, MSG_GETDEFAULT, MSG_PROFILECREATE, MSG_PROFILEDELETE,
MSG_PROFILESAVE, MSG_PROFILERENAME, MSG_PROFILERESTORE, MSG_PROFILEEXPORT, MSG_PROFILEIMPORT, MSG_PROFILESET
DAT_SETUPFILEXFER Full support.
- Supports TWFF_BMP, TWFF_TIFF.
- TWFF_JFIF is not supported on 3500/3510/3520/i810/i830.
- TWFF_BMP is not supported for the i600/i700/i800/i1800 Series when ForceAfterburner=1 in the CONST.INI file.
DAT_SETUPMEMXFER Full support.
- The Source uses the MaxBufSize to pre-allocate a scratch buffer, which for the 3000/4000 scanners must exceed the size of the largest image that the application expects to ever scan. The default size is sufficient for this, and should not be changed without consulting Eastman Kodak.
DAT_STATUS Full support.
- In some cases the status is returned by the Source Manager.
DAT_USERINTERFACE Full support.
- For MSG_ENABLEDS the SCAN, STOP and CANCEL buttons are shown.
- For MSG_ENABLEDSUIONLY the OK and CANCEL buttons are shown.
- ShowUI == FALSE is supported (no UI).
- ModalUI == TRUE is supported, but works by issuing an EnableWindow(hParent,FALSE) on the calling application.
- MSG_SETUPDS is a custom command that downloads the current settings to the scanner, but does not initiate a scanning session. The Source remains in state 4. This command has been added to allow application writers to use more than one of the Gemini modes. See also the ForceAcceptMode variable in const.ini, which can be used to disable mode checking by the Source.
- MSG_ENABLESCANNER is a custom command that starts a scanning session without downloading any settings.
DAT_WINDOW Custom: i600/i700/i900/i1100/i1200/i1300/i1400/i1800/i2000/i2900/i3000/i4000/i5000
- This utility allows an application to add and remove windows.
- A window is an index to a set of cameras, such as front_bitonal, front_color.
- Only MSG_ADDWINDOW and MSG_DELETEWINDOW are supported.
DAT_XFERGROUP Full support.
2. DG_IMAGE
DAT_CIECOLOR Unsupported.
DAT_EXTIMAGEINFO Full support.
- Please reference TWAIN_ExtImageInfo.htm for a complete list.
- MSG_GETSPECIAL is a custom feature that allows this command to be issued in state 6, before the image data is transferred, instead of state 7, after it has been transferred.
DAT_GRAYRESPONSE Unsupported.
DAT_IMAGEFILEXFER Full support.
- Supports scan error condition codes (ex: TWCC_PAPERJAM).
DAT_IMAGEINFO Full support.
DAT_IMAGELAYOUT Full support.
- Value is shared with ICAP_FRAMES.
- ICAP_SUPPORTEDSIZES will be set to TWSS_NONE if this operation is used with MSG_SET.
- The image width must at a minimum be on a 16-bit boundary. Color images must have a length that falls on an 8-bit boundary. An application can make these calculations itself when the dimensions are in TWUN_PIXELS units. The Source makes any corrections to the settings (on the application's behalf) just prior to downloading to the device.
- Because converting between ICAP_UNITS can result in loss of resolution, applications are encouraged to use TWUN_PIXELS when getting information, to guarantee that the dimensions of the image are accurately reported.
DAT_IMAGEMEMXFER Full support.
- Applications should use the Preferred value from the DAT_SETUPMEMXFER operation to set the minimum transfer buffer size. Because of the high performance of the scanners, memory transfers must move the entire image in one call to guarantee best throughput.
- Supports scan error condition codes (ex: TWCC_PAPERJAM).
DAT_IMAGENATIVEXFER Full support.
- Applications cannot use native mode transfers for anything other than uncompressed data.
- Native transfers are less efficient than memory transfers, since the Source must rotate the image around the x-axis to match the BITMAP format, and convert RGB to BGR in the case of color data.
- Supports scan error condition codes (ex: TWCC_PAPERJAM).
DAT_JPEGCOMPRESSION Full support.
- Supported for all models (except for 5000/7000/9000).
- TWPT_YUV is the only pixel type supported.
- Chroma and Luma tables may be replaced.
- Huffman tables are reported, but may not be changed.

- This utility will determine the proper ‘Color Amount’ value to use with the current ‘Color Threshold’ value, in order to save a representative stack of color documents as either color or grayscale images.
- There is no associated TW_AUTOCOLORLEARN, applications should send NULL for the data.
- Only MSG_SET and MSG_RESET are supported.
- This is only available when ICAP_AUTOCOLORCONTENT is set to Custom.

- This command may be issued at any time. It reports the raw data for the last error status report by scanner.

- Please note, that as per the specification, ICAP_ORIENTATION does not change the values of ICAP_FRAMES or DAT_IMAGELAYOUT. What it does is affect the interpretation of these values at the time they are downloaded to the device. TWOR_PORTRAIT leaves them unmodified. TWOR_LANDSCAPE flips the x and y offsets and the width and height. If ICAP_SUPPORTEDSIZES is not equal to TWSS_NONE, then the x-offset will be recalculated to center the landscaped image.

ICAP_PIXELFLAVORCODES Standard: All Models

- TWPT_BW only for /Camera_Bitonal_Both, /Camera_Bitonal_Top and /Camera_Bitonal_Bottom (ICAP_PIXELTYPE == TWPT_BW).
- TWPT_RGB only for /Camera_Color_Both, /Camera_Color_Top and /Camera_Color_Bottom (ICAP_PIXELTYPE == TWPT_RGB or TWPT_GRAY).

- Please see the ICAP_PIXELTYPE section of faq.htm.

- This is kind of a weird capability for a pixel type of TWPT_BW to have to worry about, but this is listed as a mandatory capability, so here it is.
- TWPC_PLANAR or TW_PC_CHUNKY for /Camera_Bitonal_Both, /Camera_Bitonal_Top and /Camera_Bitonal_Bottom (ICAP_PIXELTYPE == TWPT_BW).
- TW_PC_CHUNKY only for /Camera_Color_Both, /Camera_Color_Top and /Camera_Color_Bottom (ICAP_PIXELTYPE == TWPT_RGB and ICAP_PIXELTYPE == TWPT_GRAY).

- There is no performance benefit from setting this value to TRUE.
ICAP_UNITS Standard: All Models
Allowed: TWUN_INCHES, TWUN_CENTIMETERS, TWUN_PICAS, TWUN_POINTS, TWUN_TWIPS, TWUN_PIXELS
- It is advised that ICAP_UNITS be set to TWUN_PIXELS any time the Application desires to know the exact dimensions of an image.
- Selecting TWUN_PIXELS will cause ICAP_XRESOLUTION, ICAP_YRESOLUTION, ICAP_XNATIVERESOLUTION and ICAP_YNATIVERESOLUTION to report their values as percentages up from the smallest resolution supported by the current camera. For instance, if the current camera supported 200 and 300 DPI, it will report 1.0 and 1.5 when in TWUN_PIXELS.
ICAP_XFERMECH Standard: All Models
Allowed: TWSX_NATIVE, TWSX_FILE, TWSX_MEMORY
Default: TWSX_NATIVE
- The Source is designed so that TWSX_MEMORY is the most efficient transfer available. All performance benchmarks apply to this transfer mechanism, and may be less with the other options.
- TWSX_NATIVE transfers are less efficient than TWSX_MEMORY transfers because they require the Source to flip the image around the x-axis to meet the requirements of BITMAPs.
- TWSX_NATIVE transfers are less efficient with color images than TWSX_MEMORY transfers because they require the Source to convert each color pixel from RGB to BGR.
- Native transfers cannot be used with CCITT compressions.
- Compression is supported for image transfers of TWSX_FILE with an image file format of TWFF_TIFF.
- On JPEG compression is supported for image transfers of TWSX_FILE with an image file format of TWFF_TIFF (see faq.htm for more info) and TWFF_JFIF.
- The Source incorrectly allows CCITT compression with an image transfer of TWSX_FILE and an image file format of TWFF_BMP.
ICAP_XNATIVERESOLUTION Standard: All Models

- 3590 supports 200 and 300 for bitonal, and 100 and 150 for color, with the current value reflecting the setting of ICAP_XRESOLUTION.
- On the 3590/4500 the resolutions for the bitonal and color cameras are linked because of the transport speed. This means that a bitonal resolution of 200 requires a color resolution of 100, and a bitonal resolution of 300 requires a color resolution of 150. The Source enforces this behavior, changing the bitonal and color resolutions as appropriate to keep these values in sync.

Allowed: (scanner specific)
Default: 200
- ICAP_XRESOLUTION always matches the current ICAP_YRESOLUTION value. Changing one changes the other.
