This is a package for reading non-standard grayscale TIFF files. The package parses the TIFF tags for basic info such as image size, and bit depth. Currently it only reads one image per TIFF file. Furthermore, the image data has to be located in one continuous block, although TIFF ver. 6.0 allows an image to be composed of strips of data not neccessarily located consecutively. I don't parse tags other than a neccessary minimum. 8 bit image data are assumed to be unsigned i.e. 0..255, 16 bit data are assumed to be unsigned and 32 bit data represent floating point numbers.
Not supported: - - multiple images in a single TIFF file
- - compressed TIFF data
- - 4 bit pixel values
- - full implementation of image strip reading
- - parsing of ASCII type TIFF headers
- - other TIFF classes such as RGB, bi-level, JPEG
For a full overview of TIFF ver. 6.0, see http://partners.adobe.com/asn/developer/PDFS/TN/TIFF6.pdf
Tested on - - 16 bit integer and 32 bit floating point images generated by Xenogen IVIS Living Image software.
- - 16 bit images from Hamamatsu Wasabi
- - 8 bit images generated by ImageJ
Comments: - This package is offered 'as is' - no warranty implied.
- All mistakes are my own.
