/**
 * This example builds on character-encodings.php, also providing an image-based rendering.
 * This is quite slow, since a) the buffers are changed dozens of
 * times in the example, and b) It involves sending very wide images, which printers don't like!
 *
 * There are currently no test cases around the image printing, since it is an experimental feature.
 *
 * It does, however, illustrate the way that more encodings are available when image output is used.
