The Image Util APIs provides functions for common of images .
Required Header
#include <image_util.h>
Overview
Image Util API provides support for common functions of images. The API allows :
- Calculate the size of the image buffer for the specified resolution and colorspace to be used in the image util module.
- Extracts representative color from an image buffer.
The API consists of Image Util Transform,Image Util Encode/Decode.
