Comment (by Michael Koch):

 There is still the problem that the PNG or JXL output images have the
 wrong size. In the first three cases there are black or noisy borders
 visible, and in the 4th case the image size is doubled:

 Should be 5472x3648, but is 5568x3708

 http://www.astro-electronic.de/Canon_5D.dng
 Should be 6720x4480, but is 6880x4544

 http://www.astro-electronic.de/Pentax_K5.DNG
 Should be 4928x3264, but is 4992x3284

 Should be 3008x1600, but is 6016x3200
