       leptonica - image processing library


       #include <leptonica/allheaders.h>

       cc file.c -llept


       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.


       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 sample programs; read their source code if you are trying to do something similar.
