48 * Technically, the JPEG format uses the YCbCr colorspace (which is technically
49 * not a colorspace but a color transform), but per the convention of the
296 * RGB colorspace. When compressing the JPEG image, the R, G, and B
298 * colorspace conversion or subsampling is performed. RGB JPEG images can be
