LEADTOOLS 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 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.
Regions are saved automatically inside TIFF files. For more information, refer to Saving a Region. Note, however, that the ability to save a region inside a TIFF file must be unlocked. This requires the Document Imaging Toolkit, Document Imaging Suite, Medical Imaging Toolkit, or Medical Imaging Suite.
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.
This format does not support regions.
The file constants associated with this file format are:
Constant | Read Support | Write Support | Description |
Cals | 1 BPP | 1 BPP | CALS Raster file. |
Cals2 | 1 BPP | 1 BPP | CALS CCITT G4 compressed. |
Cals3 | 1 BPP | 1 BPP | CALS Fax Group 4 compressed. |
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 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
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.
The file constants associated with this file format are:
Constant | Read Support | Write Support | Description |
WfxG31Dim | 1 BPP | 1 BPP | Winfax, compressed using CCITT group 3, 1 dimension. |
WfxG4 | 1 BPP | 1 BPP | Winfax, compressed using CCITT group 4. |
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 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.
The file constants associated with this file format are:
Constant | Read Support | Write Support | Description |
FaxG31Dim | 1 BPP | 1 BPP | Raw FAX, compressed using CCITT group 3, 1 dimension. |
FaxG31DimNoEol | 1 BPP | 1 BPP | Raw FAX, compressed using CCITT group 3,1 dimension.with no EOL. |
FaxG32Dim | 1 BPP | 1 BPP | Raw FAX, compressed using CCITT group 3, 2 dimensions. |
FaxG4 | 1 BPP | 1 BPP | Raw FAX, compressed using CCITT group 4. |
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.
MicrosoftFax
AWD. This is a Microsoft FAX format.
The file constants associated with this file format are:
Constant | Read Support | Write Support | Description |
Awd | 1 BPP | 1 BPP | Microsoft FAX format. |
Required DLL: Leadtools.Codecs.Awd.Dll. For a listing of the exact DLLs needed, based on the toolkit version, refer to Files To Be Included With Your Application.
NOTE: This format does not support LEAD's redirected IO feature, therefore it cannot be used with the overloads of Load that take an inputstream parameter or FeedLoad.
LaserView LaserData
LaserView LaserData. The LaserData file format is a legacy Group 4 compressed FAX format.
The file constants associated with this file format are:
Constant | Read Support | Write Support | Description |
LaserData | 1 BPP | None | LaserData CCITT G4. |
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
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).
