-------------------------------------------------------------------------------- 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.
