Fedora Update Notification
FEDORA-2021-f5f2803fff
2021-04-19 17:43:39.804525
--------------------------------------------------------------------------------
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.
