Lossless sizes, relative to - lower is better
As it can be seen from the table above, on worst case, WebP consumes over 17 bytes and PNG over 49 bytes per one GMVC® C encoded byte.
Brief explanation of codec titles used above.

Examples of lossy compression
Date of results: 2016-05-25
Following test images are compressed with JPG, JPG2000, WebP and GMVC® CH profile using both lossless and different lossy quality ratios, and with PNG using lossless quality. Analysis graphs, below each test image, represent PSNR (in dB) against compression ratio.
