Histograms do not return information to terminal any longer.

convert logo: -format %c histogram:info:

returns nothing


Apparently one now needs to add -define histogram:unique-colors=true per viewtopic.php?f=1&t=16022

Can or has this been documented somewhere, please!

See http://www.imagemagick.org/script/formats.php. Look for the Histogram image format.

Thanks. I had no idea where to look for that.

I have about a dozen scripts now that I need to change.

In hind sight, it might have been better to disable the comment part when needed to speed up graphical histograms rather than require it be enabled for textual histograms. But too late now. So I will modify my scripts.

You are probably correct... probably more persons are counting on this that could be thought

Since the change occurred so little time ago, and as the primary beneficiary (apparently), could I suggest the option be reversed for the benefit of the many ones that probably rely on this feature?

Look for a patch in ImageMagick 6.6.1-5 Beta by sometime tomorrow.

thanks Magick and rnbc
