image processing library

Well-tested C library for some basic image processing operations, along with a description of the functions and some design methods. A full set of affine transformations (translation, shear, rotation, scaling) on images of all depths is included, with the exception that some of the scaling methods do not work at all depths. There are also implementations of binary morphology, grayscale morphology, convolution and rank order filters, and applications such as jbig2 image processing and color quantization. You will also find basic utilities for the safe and efficient handling of arrays (of strings, numbers, number pairs and image-related geometrical objects), byte queues, generic stacks, generic lists, and endian-independent indexing into 32-bit arrays.
Package version:1.69-3.1


leptonica for Debian

Sample images are included, which can be used with some of the executables.
Have fun!
