# Rockchip RGA Demos

Examples to use Rockchip RK3588s RGA2-E/RGA3 platform.

Compatible with Edge2

### Check device driver version

```
sudo cat /sys/kernel/debug/rkrga/driver_version
```

### Try Examples:

* [RGA info](/src/rga-info/) - Simple diagnostic info about system RGA

* [RGA copy](/src/rga-copy/) - Copy a RGA image in virtual memory address

* [RGA dmaheap](/src/rga-dmaheap/) - Copy a RGA image stored in a dma-heap

* [RGA dmabuf](/src/rga-dmabuf/) - Copy a RGA image stored in a dma-buf

* [RGA crop](/src/rga-crop/) - Crop into an RGA image

* [RGA rotate](/src/rga-rotate/) - Rotate an RGA image

* [RGA resize](/src/rga-resize/) - Resize an RGA image

* [RGA cvt](/src/rga-cvt) - Converts RGA image from RGB888 to NV12 color format.

* [RGA blend](/src/rga-blend) - Perform alpha blend of filter over RGA image.

* [RGA draw](/src/rga-draw) - Draw rectangles over an RGA image.
