title: Freescale i.MX8qxp Display Controller Blit Engine
description: |
A blit operation (block based image transfer) reads up to 3 source images
from memory and computes one destination image from it, which is written
back to memory. The following basic operations are supported:
* Buffer Fill
Fills a buffer with constant color
* Buffer Copy
Copies one source to a destination buffer.
* Image Blend
Combines two source images by a blending equation and writes result to
destination (which can be one of the sources).
* Image Rop2/3
Combines up to three source images by a logical equation (raster operation)
and writes result to destination (which can be one of the sources).
* Image Flip
Mirrors the source image in horizontal and/or vertical direction.
* Format Convert
Convert between the supported color and buffer formats.
* Color Transform
Modify colors by linear or non-linear transformations.
* Image Scale
Changes size of the source image.
* Image Rotate
Rotates the source image by any angle.
* Image Filter
Performs an FIR filter operation on the source image.
* Image Warp
Performs a re-sampling of the source image with any pattern. The sample
point positions are read from a compressed coordinate buffer.
* Buffer Pack
Writes an image with color components stored in up to three different
buffers (planar formats) into a single buffer (packed format).
* Chroma Resample
Converts between different YUV formats that differ in chroma sampling rate
(4:4:4, 4:2:2, 4:2:0).
