Description

The libpng package contains a library of functions for creating and manipulating PNG (Portable Network Graphics) image format files.

Setup

This testcase will use Eye of Gnome to view PNG images. EOG should be installed by default in Fedora. It is typically the default image viewer for PNG images in the file manager. The test steps below will use the command line to ensure eog is being used. For this testcase, obtain several PNG images to use as test data. Searching http://images.google.com for "PNG" is a great way to find several PNG images to use.

How to test

  1. In a terminal, navigate to the directory where you have downloaded some PNG images.
  2. For each of the PNG images execute: eog testimagename.png

Expected Results

  1. The image should load in the image viewer and display properly without any errors or crashes.
  2. Note: EOG current displays 'Gtk-Message: Failed to load module "pk-gtk-module"' when you run it, but I believe this is okay and not a problem with eog or libpng.
