The Image Util APIs provides functions for encoding and decoding of images .

Required Header

#include <image_util.h>

Overview

Image Util API provides support for encoding and decoding of images. The API allows :

Encoding/Decoding of a JPEG image.
Encoding/Decoding of a JPEG image to/from memory.
Image transformation(Colorspace conversion/Resize/Rotate/Crop) .

The decoding of a jpeg image located at a given path, to a buffer can be done by calling image_util_decode_jpeg() function and decoding of a jpeg image on memory can be done by calling image_util_decode_jpeg_from_memory(). Similarly, for encoding image_util_encode_jpeg() and image_util_encode_jpeg_to_memory() functions can be called to encode an image buffer to a jpeg image and a jpeg buffer respectively. The API also allows to transform including convert the colorspace (image_util_colorspace_e) of an image by calling image_util_transform_run() function.
