Yummy Optimizer for Gorgeous Assets

Project description

Github Discord PYPI Version Build Status Black License

YOGA is a command-line tool and a library that can:

  • convert and optimize images from various format to JPEG, PNG and WEBP,
  • convert and optimize 3D models from various formats to glTF and GLB.

Images are opened using Pillow and optimized using Guetzli (for JPEGs), Zopflipng (for PNGs) and libwebp (for WEBPs).

3D Models are converted and optimized using assimp. If models contain or reference images, they are processed by YOGA’s image optimizer.

EXAMPLE: Converting and optimizing an image from CLI:

yoga  image  input.png  output.png
yoga  image  --output-format=jpeg  --jpeg-quality=84  input.png  output.jpg
yoga  image  --help

EXAMPLE: Converting and optimizing a 3D model from CLI:

yoga  model  input.fbx  output.glb
yoga  model  --no-graph-optimization  --no-meshes-optimization  --image-output-format=jpeg  --image-jpeg-quality=84  input.fbx  output.glb
yoga  model  --help

Changelog
