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 bi

nary morphology, grayscale morphology, convolution and rank order

filters, and applications such as jbig2 image processing and col

or 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, gener

ic stacks, generic lists, and endian-independent indexing into

32-bit arrays.

OPTIONS

The example programs included with leptonica will report

their usage if you try to run them on the command line with no

arguements. Usage varies from program to program. These are sam

ple programs; read their source code if you are trying to do

something similar.
