    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.
