pixel_iterator_adapters.h File Reference

Detailed Description

Adapter layer bridging PixelIterator to encoder input iterators.

This file provides adapters that convert PixelIterator (which handles scaling, gamma, dithering) into input iterators yielding raw CRGB/Rgbw pixels that can be consumed by the new encoder functions.

Key concepts:

• PixelIterator: Stateful iterator with scaling/gamma/dithering
• ScaledPixelIterator: STL-compliant input iterator wrapping PixelIterator
• Allows new encoders to work with both raw pixel arrays and PixelIterator
