Embedded Spritesheet Metadata Demo

Embedded Spritesheet Metadata Demo provides a method and tool for embedding metadata directly into PNG spritesheet files, removing the need to distribute separate metadata files such as JSON or XML alongside the image. By storing metadata within a standard iTXt chunk in the PNG file, the tool enables sprite coordinates and animation data to be bundled with the spritesheet itself. This approach streamlines asset management for users who work with spritesheets, such as game developers and designers.

JSON, as well as other custom formats. Users can select a base PNG image, choose a metadata file in formats like JSON or XML, specify the metadata key, and embed the metadata into the PNG. The process allows for multiple animations and associated data to be specified within a single image file. The tool also demonstrates how to extract and parse the embedded metadata, making it accessible for client applications to retrieve sprite and animation information directly from the PNG.

js example is provided to illustrate programmatic embedding of metadata, and the tool itself is accessible via a web interface. The specification and tool are released into the public domain under the CC0 license, allowing unrestricted use and modification. The project is attributed to Chris McCormick.

Embedded Spritesheet Metadata Demo serves as both a demonstration and a practical utility for embedding and extracting spritesheet metadata, targeting workflows that benefit from consolidating image and metadata assets.
