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:

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.
