12 # First: xcf2png by default calls zcat rather than gzcat. This is
13 # totally always broken; zcat forces a .Z extension on its input
14 # filename. So we can't rely on xcf2png's default behavior. But it
15 # offers -Z for a custom decompression program.
16 #
17 # BUT: Gimp produces gz files with some padding zeros because, I don't
18 # know, someone might want to save their compressed xcfs to DECtape.
19 # gzip has a -q option to not *print* the warning associated with this
20 # harmless thing, but then goes ahead and exits non-zero anyway, which
21 # makes xcf2png barf and die before writing anything even though it
22 # got perfectly good data.
23 #
24 # So: 1) use gunzip, 2) manually feed it to xcf2png, 3) hope nothing is
25 # set to die based on pipe status, 4) hope that if the xcf data is
26 # actually busted xcf2png will do something helpful.
