Detailed Description

This class provides static methods to compress and decompress data in JPG format.

Constructor & Destructor Documentation

odcore::wrapper::jpg::JPG::~JPG ( )

virtual

bool odcore::wrapper::jpg::JPG::compress	(	void *	dest,
		int &	destSize,
		const uint32_t &	width,
		const uint32_t &	height,
		const uint32_t &	bytesPerPixel,
		const uint8_t *	rawImageData,
		const uint32_t &	quality
	)

static

This method compresses raw image data using a JPG compressor.

Parameters

dest	Pointer to destination buffer to receive the compressed image data.
destSize	Size of destination buffer that will be set to the actual amount of bytes used thereof.
width	Raw image's width.
height	Raw image's height.
bytesPerPixel	Raw image's bytes per pixel (channels).
rawImageDate	Raw image data.
quality	Compression rate (must be between 1 and 100).

unsigned char * odcore::wrapper::jpg::JPG::decompress	(	const unsigned char *	src,
		const uint32_t &	srcSize,
		int *	width,
		int *	height,
		int *	actualBytesPerPixel,
		const uint32_t &	requestedBytesPerPixel
	)

static

This method decompresses a JPG compressed image.

Parameters

src	Pointer to a buffer containing the compressed image data.
srctSize	Size of buffer.
width	Decompressed image's width.
height	Decompressed image's height.
actualBytesPerPixel	Decompressed image's bytes per pixel (channels).
requestedBytesPerPixel	Expected decompressed image's bytes per pixel (channels).

Returns: Pointer to the decompressed image that MUST be released by the callee or NULL in the case of an error.
