texture_atlas_transformer #

A transformer to build JSON Atlas files for inclusion in games.

Example pubspec.yaml:

transformers:
  - texture_atlas_transformer:
      output_dir: web/assets/textures
      scale: 0.125
      files:
        flying:
          frames:
            - "web/assets/green_flapper/Transparent PNG/flying/*.png"

Options #

• output_dir: Output directory to generate files into.
• scale: Either a num or a Map (ex. {'x': 0.5, 'y': 1.0}). This ratio is applied to every frame.
• resize: Same as scale; however, each frame is resized to the exact size, instead of being scaled.
• files: A Map of Strings to atlas definitions.
• extension: The output image extension. Default: png. Supports jpg, jpeg, gif, and tga.

Atlas Definitions #

• frames: A List of Strings representing files to be combined. Supports globbing.
• animations: A Map of Strings to animations.
