TIFF CCITT and Other FAX Formats

LEADTOOLS supports writing of the following 1-bit formats that is commonly used in FAX transmissions:

TIFF

$image\sqrblit.gif$ TIFF CCITT. These are compressed TIFF files that are commonly used for FAX transmission and document imaging.

$image\sqrblit.gif$ TIFF CCITT Group 3. These are TIFF CCITT files in a format that is more advanced and more compressed than TIFF CCITT. LEADTOOLS supports both 1-dimension and 2-dimension variations of this format.

$image\sqrblit.gif$ TIFF CCITT Group 4. These are TIFF CCITT files in a format that is more advanced and more compressed than TIFF CCITT Group 3.

For more information refer to Tagged Image File Format (TIFF).

CALS

$image\sqrblit.gif$ CALS Raster (Type 1, 2, 3, and 4). These are CCITT Group 4 CALS raster files. CALS is a United States government standard. CALS3 are multi-page files.

The file constants associated with this file format are:

Constant	Write Support	Description
FILE_CALS	1 BPP	[50] CALS Raster file.
FILE_CALS2	1 BPP	[130] CALS CCITT G4 compressed.
FILE_CALS3	1 BPP	[131] CALS Fax Group 4 compressed.
FILE_CALS4	1 BPP	[129] CALS CCITT G4 Tiled.

Required DLL: LFCAL. For a listing of the exact DLLs needed, refer to ePrint Files.

IOCA

$image\sqrblit.gif$ IOCA (ICA). This is the Image Object Content Architecture developed by IBM. LEADTOOLS supports these files in an MO:DCA wrapper with embedded 1-bit CCITT Group 3 or Group 4 images. LEADTOOLS also supports IOCA files without an MO:DCA wrapper.

For more information refer to Image Object Content Architecture Format (IOCA/MODCA).

WinFax

$image\sqrblit.gif$ WinFax Group 3. This is a FAX format created by Delrina for Group 3 support.

$image\sqrblit.gif$ WinFax Group 4. This is a FAX format created by Delrina for Group 4 support.

The file constants associated with this file format are:

Constant	Write Support	Description
FILE_WFX_G3_1D	1 BPP	[69] Winfax, compressed using CCITT group 3, 1 dimension
FILE_WFX_G4	1 BPP	[70] Winfax, compressed using CCITT group 4.

Required DLL: LFWFX. For a listing of the exact DLLs needed, refer to ePrint Files.

Raw FAX

$image\sqrblit.gif$ FAX Group 3. This is a raw FAX format (without a header) for Group 3 support. LEADTOOLS supports both 1-dimension and 2-dimension variations of this format.

TIFF-FX

$image\sqrblit.gif$ TIFF-FX. These are Internet Fax files developed and used by Xerox. This format supports several types of compression, which allows the user or developer to use the compression that best suits his or her needs. In addition, this file format can be extended as the need arises. The following modes are supported:

Minimal Black and White: This mode uses binary MH compression (T.4).

Extended Black and White: This mode uses binary MH, MR and MMR compression (T.4 and T.6).

Lossless JBIG Black and White: This mode uses JBIG compression (T.85, T.82).

Lossy Color and Grayscale: This mode uses JPEG compression (T.42, T.81).

Lossless Color and Grayscale: This mode uses JBIG compression (T.43, T.82).

The default extensions used by this format is: TIFX, TIFF.

This file format does support multi-page files.
