------------------------------------------------------------------------------- - Fedora Update Notification FEDORA-2021-d781fa9f44 2021-05-07 01:01:44.952333 ------------------------------------------------------------------------------- -
Name : djvulibre Product : Fedora 34 Version : 3.5.27 Release : 28.fc34 URL : http://djvu.sourceforge.net/ Summary : DjVu viewers, encoders, and utilities Description : DjVu is a web-centric format and software platform for distributing documents and images. DjVu can advantageously replace PDF, PS, TIFF, JPEG, and GIF for distributing scanned documents, digital documents, or high-resolution pictures. DjVu content downloads faster, displays and renders faster, looks nicer on a screen, and consume less client resources than competing formats. DjVu images display instantly and can be smoothly zoomed and panned with no lengthy re-rendering.
DjVuLibre is a free (GPL'ed) implementation of DjVu, including viewers, decoders, simple encoders, and utilities. The browser plugin is in its own separate sub-package.
