Tagged image file format, are one of the most widely supported file formats for storing bit-mapped images on personal computers (Windows, Linux and Mac).

This class supports reading 1 bit, 4, 8, 16, and 24 bit color, CMYK, black and white and grayscale Multi Page and single page images. The supported compression types include TifPackbits, JPEG, and LZW for color, Modified CCITT, and CCITT Group 3 and Group 4 Fax for monochrome images.

This class supports reading Tiff Version 6 and earlier files. Not all version 6 TifJpeg compressed tiff files are implemented consistently, and some may not be supported. Version "7" TifJpeg compressed tiff files as explained in Tiff Technical note #2 are fully supported.

Some monochrome images may look inverted compared to the XP Viewer. This is because the Windows XP previewer through SP2, does not follow the Tiff specification and honor the Photometric interpretation specified in the image file directory for the image. All images are treated as if they where Min as White or White pixels = 0 bits even if this is not true. This tag is honored for grayscale images.
