Image Util Encode/Decode

The Image Util Encode/Decode 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 of a JPEG/PNG/GIF/BMP image.
  • Decoding of a JPEG/PNG/GIF/BMP image. Encoding supports gif images including the animated, but decoding gif does not support the animated.

The decoding of a jpeg/png/gif/bmp image located at a given path, to a buffer can be done by calling image_util_decode_run() function and decoding of a jpeg image on memory can be done by calling image_util_decode_set_output_buffer(). Similarly, for encoding image_util_encode_run() and image_util_encode_set_output_buffer() functions can be called to encode an image buffer to a jpeg/png/gif/bmp image and a buffer respectively.

unsigned int  time_delay 
)

Encodes an image and adds the encoded image to the frames of the animated GIF.

Since :
5.5
Remarks:
This function should be called for each image which you want to add to the animated GIF. Eeach image should be the same size.
The supported colorspace is IMAGE_UTIL_COLORSPACE_RGBA8888.

[in]handleThe handle of encoding an animated GIF
[in]imageThe handle of the image for each frame
[in]time_delayThe time delay between image and the next image (in 0.01sec increments)
Returns:
0 on success, otherwise a negative error value

int image_util_agif_encode_save_to_buffer ( image_util_agif_encode_h  handle,
unsigned char **  buffer,
size_t *  buffer_size 
)

Saves the animated GIF image to the buffer.

After the data has been written to a buffer, the file cannot be modified. In other words,
it is not possible to add frames to the buffer.
However, the encoder can be still used after the data is written.
For example, although you write the data to one buffer(B0),
you can do the following operations:

1. Add frames 1-10 to the encoder.
2. Save the data in the encoder to another buffer(B1).
3. Add more frames (11-20) to the same encoder.
4. Save the data in the encoder to the other buffer (B2)
It is not possible to save the changed data to B1 file used in step 4.

Since :
5.5
Remarks:
The buffer should be released using free() after using it.
Parameters:
[in]handleThe handle of encoding an animated GIF
[out]bufferThe buffer in which the animated GIF is saved
[out]buffer_sizeThe size of the buffer
Returns:
0 on success, otherwise a negative error value
