JPEG & JPEG2000 compression ratio comparison

Example images for different JPEG2000 compression ratios:
    * lossless
    * ratio 10:1 (2.40 bpp)
    * ratio 15:1 (1.60 bpp)
    * ratio 20:1 (1.20 bpp)
    * ratio 25:1 (0.96 bpp)
    * ratio 30:1 (0.80 bpp)
    * ratio 35:1 (0.69 bpp)
    * ratio 40:1 (0.60 bpp)
    * ratio 45:1 (0.53 bpp)
    * ratio 50:1 (0.48 bpp)
