Module:SpriteFile

This module implements a replacement for {{sprite}}. It should generally be invoked directly on template pages, rather than using the sprite template.

Parent arguments are automatically merged with directly passed arguments (the latter overwriting the former) and all arguments are normalized to trim whitespace and set empty arguments to nil.

Dependencies

• Module:ProcessArgs
• File:Grid Unknown.png
