Changelog

[Unreleased]

Added Bg8 type for 8bpp paletted backgrounds
Added toBg8(bg16) for direct color to 8bpp paletted conversion
Added loadBg8(filepath) which supports indexed PNGs
- This allows you to preserve the existing palette when loading an image.
Added indexed parameter to loadBg4
- This provides a stricter way of loading 4bpp backgrounds, expecting a well-formed palette rather than deducing the palettes using palbuilder.
Added readPng(filepath) as an easy way to get a useful nimpng.PNG object
