Name : gd
Product : Fedora 29
Version : 2.2.5
Release : 8.fc29
URL : http://libgd.github.io/
Summary : A graphics library for quick creation of PNG or JPEG images Description :
The gd graphics library allows your code to quickly draw images complete with lines, arcs, text, multiple colors, cut and paste from other images, and flood fills, and to write out the result as a PNG or JPEG file. This is particularly useful in Web applications, where PNG and JPEG are two of the formats accepted for inline images by most browsers. Note that gd is not a paint program.
