Questions tagged [libtiff]

Open source, cross-platform library and tools for TIFF images.

Project homepage

This software provides support for the Tag Image File Format (TIFF), a widely used format for storing image data.

Included in this software distribution is a library, libtiff, for reading and writing TIFF, a small collection of tools for doing simple manipulations of TIFF images on UNIX systems, and documentation on the library and tools. A small assortment of TIFF-related software for UNIX that has been contributed by others is also included.

The library, along with associated tool programs, should handle most of your needs for reading and writing TIFF images on 32- and 64-bit machines. This software can also be used on older 16-bit systems though it may require some effort and you may need to leave out some of the compression support.
