Description (last modified by mtbcarroll)
With Bio-Formats 5.1.2,
bfconvert test_images_good/ome-tiff/multi-channel-4D-series.ome.tif 'S%s_C%c_Z%z_T%t.png'
seems to work fine but for S0_C0_Z0_T0.png libpng-based viewers report,
libpng warning: acTL: CRC error
and the resulting PNG file is smaller than from old versions. I can't actually get GraphicsMagick to open the file at all.
This regression appears to have occurred between versions 4.4.4 and 4.4.5.

Fixes #12943.

You may also have a look at Agilo extensions to the ticket.
Bumping up to 5.1.3 given the severity. This might merit a new (or expanded?) manual testing scenario as well.
