libleptonica-dev - 1.76.0-1+deb10u2 main

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.
