Problem with photometric interpretation modification

[antoine.lamaison]

Hi,

I would like to modify the tiff format of an image and change the photometric-interpretation of an image.
My image polarity is 'min-is-black' and I want to change it to 'min-is-white' with this command line

Code: Select all

convert source.tif -define tiff:quantum:polarity=min-is-white dest.tif

The command line doesn't trigger any error, but when I type :

Code: Select all

identify -verbose dest.tif

the tiff:photometric is still set to 'min-is-black'

How can I change this parameter ?

Remove the tiff: and just use quantum:polarity=min-is-white.

It works, Thanks !

Updated the command line options page for "-define" in both IMv6 and IMv7

Hmmm the option "-distribute-cache" appears to have been added to IMv6 but not to IMv7!!!
