LEADTOOLS for WPF supports reading and writing of the following 1-bit formats that are commonly used in FAX transmissions:

TIFF

• TIFF CCITT. These are compressed TIFF files that are commonly used for FAX transmission and document imaging.
• TIFF CCITT Group 3. These are TIFF CCITT files in a format that is more advanced and more compressed than TIFF CCITT. LEADTOOLS for WPF supports both 1-dimension and 2-dimension variations of this format.
• TIFF CCITT Group 4. These are TIFF CCITT files in a format that is more advanced and more compressed than TIFF CCITT Group 3.
• TIFF Class F. Class-F is the TIFF extension for fax documents. LEADTOOLS supports Class-F compatible tags.

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

CALS

• 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 multipage files.

The file constants associated with this file format are:

WIC Codec CLSID	WIC Codec Subformat	RasterImageViewer.Save File Constant	Read Support	Write Support	Description
CLSID_WICLeadCalsEncoder	WICLeadSubFormatCals	Cals	1 BPP	1 BPP	CALS Raster file.
CLSID_WICLeadCalsEncoder	WICLeadSubFormatCals2	Cals2	1 BPP	1 BPP	CALS CCITT G4 compressed.
CLSID_WICLeadCalsEncoder	WICLeadSubFormatCals3	Cals3	1 BPP	1 BPP	CALS Fax Group 4 compressed.
CLSID_WICLeadCalsEncoder	WICLeadSubFormatCals4	Cals4	1 BPP	1 BPP	CALS CCITT G4 Tiled.

Required DLL: Leadtools.Codecs.Cal.Dll. For a listing of the exact DLLs needed, based on the toolkit version, refer to Files To Be Included With Your Application.

IOCA

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

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

WinFax

• WinFax Group 3. This is a FAX format created by Delrina for Group 3 support.
• WinFax Group 4. This is a FAX format created by Delrina for Group 4 support.

Required DLL: Leadtools.Codecs.Wfx.Dll. For a listing of the exact DLLs needed, based on the toolkit version, refer to Files To Be Included With Your Application.

Raw FAX

• FAX Group 3. This is a raw FAX format (without a header) for Group 3 support. LEADTOOLS for WPF supports both 1-dimension and 2-dimension variations of this format.
• FAX Group 4. This is a raw FAX format (without a header) for Group 4 support.

Required DLL: Leadtools.Codecs.Fax.Dll. For a listing of the exact DLLs needed, based on the toolkit version, refer to Files To Be Included With Your Application.

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 multipage files.

The file constants associated with this file format are:

RasterImageViewer.Save File Constant	Read Support	Write Support	Description
