Description
This document provides a complete list of bitmap formats supported by the RZA1H Target.
These formats define how pixel color and alpha data are stored in memory. The RZA1H extended bitmap formats support alpha-only, RGB, ARGB, and JPEG compressed images formats to address different memory, performance, and visual quality requirements.
1). Alpha Only Formats
Alpha formats (A1/A4/A8) are primarily used for masking and blending operations.
