This class can build pixel-perfect file type icons based on a extension name and its associated mime type.

Icons are build based on a template file on which then a colored label with the extension is printed. This makes it easy to create a consistent look in your application without the problem of missing the icon for a certain file type.

Currently 16x16 and 32x32 images can be generated.

See createall.php for building all icons at once, otherwise just refer to the source code comments. It's relatively straight forward.

Color and template files are first matched against a extension-<ext> entry. If that is not found the mime type is matched.

For matching mime types in color and template setup the mime type of an extension is broken up parts at the charcters /, . and - and connected with a - again.

Partial matches are then tried per segment. Example:

application/vnd.openxmlformats-officedocument.wordprocessingml.document becomes application-vnd-openxmlformats-officedocument-wordprocessingml-document. It could be matched with application-vnd-openxmlformats or application. The longest match wins. Note: wordprocessingml would not match!

This can be improved, pull requests more than welcome!

• define more colors
• create more templates for common formats
• add more output sizes
