関数

decompress	(	const void *	data,
		void *	dst,
		DecompressType	type
	)

decompresses data using the suported type

引数:

	dst	the destination to decompress to
	data	the data to decompress
	type	the type of data to decompress

例:

Graphics/Backgrounds/16bit_color_bmp/source/template.cpp.

decompressStream	(	const void *	data,
		void *	dst,
		DecompressType	type,
		getByteCallback	readCB,
		getHeaderCallback	getHeaderCB
	)

decompresses data using the suported type (only LZ77Vram, HUFF, and RLEVram support streaming)

引数:

	dst	the destination to decompress to
	data	the data to decompress
	type	the type of data to decompress
	readCB	a callback to read the next byte of data
	getHeaderCB	a callback to read the 32 byte header
