This project is a collection of test images and a simple tool to display images for Embedded Linux systems.

• cmake ./
• ./lcd-test images/lcd-test.png

If you are using OpenEmbedded, use the following recipe:

The project was born out of a need to be able quickly test LCD displays in Embedded Linux systems. It seemed I never had a quick way to display a test image on a LCD. Utilities (oeg) that are normally used to do this have a ton of dependencies. The display-image utility only depends on Gtk2 and its dependencies, which is typically available for most systems.

• lcd-test.png: simple gradients and color tests. Also includes a 1px white line around the border that can be used to check alignment.

Test images are generated using node-canvas. To re-generate the images:

• make sure you have a recent version of node installed
• edit gen-images.js and enter your LCD size
• npm install
• node gen-images.js
• TODO
