DMA2D Features
|
||
|
|
----------------------------
|
||
|
|
|
||
|
|
- fill specific color
|
||
|
|
Fill part or all of the target image with a specific color
|
||
|
|
- mem to mem copy
|
||
|
|
Copy part or all of the source image to part or all of the target image
|
||
|
|
- mem to mem with pixel conversion
|
||
|
|
Copy part or all of the source image to part or all of the target image through pixel format conversion
|
||
|
|
- mem to mem with pixel conversionwith and blending
|
||
|
|
Part or all of the two source images with different pixel formats are mixed,
|
||
|
|
and the result is copied to the part or the entire target :image with different color formats
|
