--------------------------------------------------------------------------------

Name        : leptonica
Product     : Fedora 33
Version     : 1.80.0
Release     : 3.fc33
URL         : https://github.com/danbloomberg/leptonica
Summary     : C library for efficient image processing and image analysis operations
Description :
The library supports many operations that are useful on
 * Document images
 * Natural images

Fundamental image processing and image analysis operations
 * Rasterop (aka bitblt)
 * Affine transforms (scaling, translation, rotation, shear)
   on images of arbitrary pixel depth
 * Projective and bi-linear transforms
 * Binary and gray scale morphology, rank order filters, and
   convolution
 * Seed-fill and connected components
 * Image transformations with changes in pixel depth, both at
   the same scale and with scale change
 * Pixelwise masking, blending, enhancement, arithmetic ops,
   etc.
