Decodes Image data into pixel data using a cipher.

Parameters:

data	The encoded pixel data.
cipher_key	The key to use as cipher.
size	The size, in bytes, of the encoded pixel data.
w	A pointer to the unsigned int to hold the width in pixels.
h	A pointer to the unsigned int to hold the height in pixels.
alpha	A pointer to the int to hold the alpha flag.
compress	A pointer to the int to hold the compression amount.
quality	A pointer to the int to hold the quality amount.
lossy	A pointer to the int to hold the lossiness flag.

Returns:

The image pixel data decoded

This function takes encoded pixel data and decodes it into raw RGBA pixels on success.

The other parameters of the image (width, height etc.) are placed into the values pointed to (they must be supplied). The pixel data is a linear array of pixels starting from the top-left of the image scanning row by row from left to right. Each pixel is a 32bit value, with the high byte being the alpha channel, the next being red, then green, and the low byte being blue. The width and height are measured in pixels and will be greater than 0 when returned. The alpha flag is either 0 or 1. 0 denotes that the alpha channel is not used. 1 denotes that it is significant. Compress is filled with the compression value/amount the image was stored with. The quality value is filled with the quality encoding of the image file (0 - 100). The lossy flags is either 0 or 1 as to if the image was encoded lossily or not.

On success the function returns a pointer to the image data decoded. The calling application is responsible for calling free() on the image data when it is done with it. On failure NULL is returned and the parameter values may not contain any sensible data.

Since (EFL) :

Since :

3.0

Encodes image data for storage or transmission using a cipher.

Parameters:

data	A pointer to the image pixel data.
cipher_key	The key to use as cipher.
size_ret	A pointer to an int to hold the size of the returned data.
w	The width of the image in pixels.
h	The height of the image in pixels.
alpha	The alpha channel flag.
compress	The compression amount.
quality	The quality encoding amount.
lossy	The lossiness flag.

Returns:

The encoded image data.

This function stakes image pixel data and encodes it with compression and possible loss of quality (as a trade off for size) for storage or transmission to another system.

The data expected is the same format as returned by eet_data_image_read. If this is not the case weird things may happen. Width and height must be between 1 and 8000 pixels. The alpha flags can be 0 or 1 (0 meaning the alpha values are not useful and 1 meaning they are). Compress can be from 0 to 9 (0 meaning no compression, 9 meaning full compression). This is only used if the image is not lossily encoded. Quality is used on lossy compression and should be a value from 0 to 100. The lossy flag can be 0 or 1. 0 means encode losslessly and 1 means to encode with image quality loss (but then have a much smaller encoding).

On success this function returns a pointer to the encoded data that you can free with free() when no longer needed.
