Description

tiff2biff is a wrapper function that decides which one of the routines below to use, depending on what kind the TIFF image is (bi-level, grayscale, palette or rgb). In the case of a palette image, the parameters coltab and numColors reflect the palette colormap.

Byte-ordering between little-endian and big-endian machines is handled automatically.

The conversions are according to TIFF specification 6.0 and use the libtiff library by Sam Leffler. This library must exist on your system, it is not supplied with XITE. If you get problems with importing TIFF images from other applications, make sure those applications are also TIFF 6.0 compliant.

TIFF grayscale images:

tiff2biff1 converts a TIFF bi-level (black-and-white, 1-bit samples) image to a BIFF unsigned byte band.

tiff2biff2 converts a TIFF grayscale (2-bit samples) image to a BIFF unsigned byte band.

tiff2biff4 converts a TIFF grayscale (4-bit samples) image to a BIFF unsigned byte band.

tiff2biff8 converts a TIFF grayscale (8-bit samples) image to a BIFF unsigned byte band.

tiff2biff16 converts an unsigned short TIFF image to an unsigned short BIFF band.

tiff2biff32i converts a signed integer TIFF image to a signed integer BIFF band

tiff2biff32fp converts a 32-bit floating point TIFF image to a REAL BIFF band

tiff2biff64 converts a 64-bit floating point TIFF image to a DOUBLE BIFF band

TIFF palette (pseudocolor) images:

tiff2biff1p converts a TIFF bi-level (1-bit samples) palette image to a BIFF unsigned byte band and colortable.

tiff2biff2p converts a TIFF palette (2-bit samples) image to a BIFF unsigned byte band and colortable.

tiff2biff4p converts a TIFF palette (4-bit samples) image to a BIFF unsigned byte band and colortable.

tiff2biff8p converts a TIFF palette (8-bit samples) image to a BIFF unsigned byte band and colortable.

TIFF rgb color images:

tiff2biff8c converts an unsigned byte TIFF 3*8-bit rgb image to a BIFF unsigned byte three-band image

tiff2biff16c converts an unsigned short TIFF 3*16-bit rgb image to an unsigned short three-band BIFF image

tiff2biff32ic converts a signed integer 3*16-bit rgb TIFF image to a signed integer three-band BIFF image

tiff2biff32fpc converts a 32-bit floating point rgb TIFF image to a REAL BIFF three-band image

tiff2biff64c converts a 3*64-bit floating point rgb TIFF image to a DOUBLE BIFF three-band image
