Examples to use Amlogic GE2D 2D graphics platform.

Compatible with VIM3/3L/1S/4;

GE2D Capabilities:

• Max 8192px x 8192px x 4 planes, source(s) and destination canvas size
• RGB, YUV data types of 16, 24, 32 bit depth
• Uses ION buffer, or DMA buffer (with ge2d_cma_reserved)
• Operation types:
  • Blend (eg. alpha image operations)
  • Blit (no scaling, eg. cropping)
  • Stretchblit (scaled operation, eg. resize)
  • Fillrectangle (drawing pixels on canvas)

Try Examples:

• GE2D ionbuf - Process operations through ION-BUF allocated memory

• GE2D dmabuf - Process operations through GE2D-DMA allocated memory

• GE2D crop - Crop the image

• GE2D cvt - Convert the image from RGBA8888 to NV12 color format

• GE2D rotate - Rotate the image

• GE2D resize - Resize the image

• GE2D blend - Perform alpha blend operation over the image

• GE2D draw - Draw rectangles over the image
