RZA1HBitmapConverter

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. 
 These bitmap converters are supported only on the target. Windows simulation uses the default bitmap converter. 
 Alpha Only Formats 
 Alpha formats (A1/A4/A8) are primarily used for masking and blending operations.
