NAME
leptonica - image processing library
SYNOPSIS
#include <leptonica/allheaders.h>
cc file.c -llept
DESCRIPTION
This manual page documents briefly the leptonica image processing library.
Leptonica is a 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.
OPTIONS
Most example programs included with leptonica will report their usage if you try to run
them on the command line with no arguments. Usage varies from program to program. These
are sample programs; read their source code if you are trying to do something similar.
