IntergraphRLE (ITG) and Intergraph Raster File Formats (CIT, RLE, CRL, T29, COT, T27, RGB)

Intergraph File Format

Intergraph is a monochrome bitmap format developed by Intergraph. LEADTOOLS supports the RLE and CIT versions of this file format.

The default extensions used by this format are: ITG and CIT.

This file format does not support stamps or Lossless JPEG compression. For this file format, LEAD supports CCITT G4 and RLE compression.

Currently LEAD writes the ITG and CIT format.  

File constants associated with this file format are:

Constant Read Support Write Support Description
FILE_INTERGRAPH_RLE 1 BPP 1 BPP [122] ITG, Intergraph RLE compressed file.
FILE_INTERGRAPH_CCITT_G4 1 BPP 1 BPP [301] ITG, Intergraph CCITT G4 compressed file.

Required DLLs and Libraries

Platforms

Win32, x64.

Intergraph Raster File Format (INGR)

The Intergraph Raster File Format is the native file format used by Intergraph software applications to store raster data. It is manifested in several internal data formats. For more information, refer to http://www.intergraph.com/.

The default extensions depend upon the bits per pixel and the compression used, as follows:

Extension Description
CIT INGR, 1BPP CCITT G4 compressed file
RLE INGR, 1BPP RLE compressed file
CRL INGR, 8BPP Color or Gray RLE compressed file
T29 INGR, 8BPP Color or gray adaptive RLE compressed file
COT INGR, 8BPP Color or gray uncompressed file
T27 INGR, 24BPP Adaptive RLE compressed file
RGB INGR, 24BPP RGB uncompressed file

This file format does not support stamps or Lossless JPEG compression. LEAD supports CCITT G4 and RLE compressed, adaptive RLE compressed, and uncompressed files.

Currently LEAD writes the  CIT, RLE, CRL, T29, COT, T27, and RGB formats. 

File constants associated with this file format are:

Constant Read Support Write Support Description
FILE_ING_CG4 1 BPP 1 BPP [375] INGR, CCITT G4 compressed file
FILE_ING_RLE 1 BPP 1 BPP [373] INGR, RLE compressed file
FILE_ING_RLE 8 BPP 8 BPP [373] INGR, Color or gray RLE compressed file
FILE_ING_ADRLE 8 BPP 8 BPP [374]  INGR, Color or gray adaptive RLE compressed file
FILE_ING 8 BPP 8 BPP [372] INGR, Color or gray uncompressed file
FILE_ING_ADRLE 24 BPP 24 BPP [374]  INGR, Adaptive RLE compressed file
FILE_ING 24 BPP 24 BPP [372] INGR, RGB uncompressed file
