IM v6.8.1-6 on Windows 8.1.

Code: Select all

convert rose: -define histogram:unique-colors=false histogram:h.png

convert rose: -define histogram:unique-colors=false histogram:h.gif
Both commands work, but the outputs are both MIFF instead of PNG or GIF.

Edit for clarity: the output files are names h.png and h.gif, but the actual filetype as shown by "identify" is MIFF for both.

I can confirm. I get the properly named files, but identify shows them as MIFF. IM Q16 Mac OSX

Thanks for the workaround.

The command I showed used to work, as documented in, eg in v6.9.0-0.
