cannot use nconvert to read or write IFF/ILBM

Hi,

All my attempts resulted in "not implemented". Is that expected? Full trace:

Please try this code:

Code: Select all

nconvert -o copy.iff -out lbm temp.ppm

Tested NConvert 7.10 32-bit and also NConvert 7.12 64-bit.

Read or write of at least one format seems not to be supported, I'm not sure which...
