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.
| Serial No. | Format | Description |
|
1 |
RZA1HExtendedBitmapFormatA1
|
1-bit alpha mask. |
| 2 |
RZA1HExtendedBitmapFormatA4
|
4-bit alpha channel. |
| 3 |
RZA1HExtendedBitmapFormatA8
|
8-bit alpha channel. |
RGB/ARGB Formats
RGB/ARGB formats balance memory usage and visual quality depending on color depth and transparency needs.
| Serial No. | Format | Description |
|
1 |
RZA1HExtendedBitmapFormatRGB565
|
16-bit RGB (5-6-5), no alpha. |
| 2 |
RZA1HExtendedBitmapFormatARGB8888
|
32-bit ARGB, 8 bits per channel. |
| 3 |
RZA1HExtendedBitmapFormatARGB1555
|
16-bit ARGB with 1-bit alpha. |
| 4 |
RZA1HExtendedBitmapFormatARGB4444
|
16-bit ARGB, 4 bits per channel. |
| 5 |
RZA1HExtendedBitmapFormatXRGB8888
|
32-bit RGB, unused alpha byte. |
| 6 |
RZA1HExtendedBitmapFormatR8G8B8A8
|
32-bit RGBA, 8 bits per channel. |
JPEG Compressed Image Format
JPEG format enables efficient storage of large images with reduced memory requirements.
| Serial No. | Format | Description |
| 1 |
RZA1HExtendedBitmapFormatJpg
|
JPEG compressed image format. |
