==========================================

   :alt:

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

* convert and optimize images from various format to JPEG and PNG,
* convert and optimize 3D models from various formats to `GLB`_.

**Images** are opened using Pillow_ and optimized using Guetzli_ (for JPEGs) and
Zopflipng_ (for PNGs).

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

Convert and optimize 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

Convert and optimize 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
