Fedora 44 leptonica Significant Bug Resolution Advisory 2026-a72f110dcd

fedora
Calendar Grey July 3, 2026
Dist Fedora Esm H88
Latest Fedora advisory details leptonica updates resolving GCC issues and improving image processing capabilities for aarch64.
This update includes new upstream snapshots of openQA and os-autoinst, with the usual mix of fixes and improvements

Summary

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.

Update Information:

This update includes new upstream snapshots of openQA and os-autoinst, with the usual mix of fixes and improvements. See upstream changelogs for details. For leptonica, this update removes an incorrect workaround for a GCC compilation issue, since GCC is now fixed. This should resolve incomplete processing of files on aarch64. Without this fix, os-autoinst's test suite fails.
