Here is the caller graph for this function:

std::string JPEGcompressImage	(	int	wid,
		int	ht,
		int	bpp,
		const byte *	image_data,
		int	quality
	)

Return a binary string containing the JPEG-compressed data of this raster image, which is wid x ht pixels, and each pixel bpp bytes (must be either 1, for greyscale; or 3, for RGB).

quality controls the compression rate, from quality == 0, tiny compressed image, very low quality quality == 100, huge compressed image, very high quality

This code derived from the "example.c" that ships with libjpeg; see that file for comments.
