This class can render images with text using graphics as fonts.

It takes a text string and creates an image on which the characters of the string are displayed using separate image files to render each character.

The text may be aligned to the left, right, center or be justified.

The image width may be limited so the text is wrapped if it exceeds that width limit.

The character graphics may be mapped to image files with the same base name in a given directory. Alternatively an array may be passed to define the paths of the character image files.

The generated image may be saved to a file or displayed as the current script output in any of the formats supported by the PHP GD image extension.

Prize: One downloadable e-book of choice by O'Reilly		 Some applications need to use buttons or other types of images on which a given text message is rendered.

If there is no font with characters with a certain aspect that you want to use, you can always create images in PHP by pasting other images that represent the text characters of the message you want to display.

In some cases you may need to render text formatted with special justification.

This class provides solution to render text on images using separate image files as font characters.

You can format the text using several types of justification, in such way that if the text does not fit a given limit width, it can nicely wrap the text around multiple lines.
