I just downloaded this release and was trying the new option -features now listed on the options page and in the changelog

convert Htexture.png -features 5 Htexture_f5.png
convert: unrecognized option `-features' @ error/convert.c/ConvertImageCommand/1512.


Is this not yet ready for prime time?

Is it supposed to make multiple images for each feature for each channel and each direction? Or does it just list feature stats to the terminal?

What is the correct syntax to use? Can one select a particular feature and make an output image?

Can you provide an example syntax?

Thanks

Fred

It works for logo: but not for this image:



identify -features 5 -verbose Htexture.png

Is it limited to certain image types?

We can reproduce the problem you posted and have a fix. Look for it in ImageMagick 6.5.9-2 available sometime tomorrow.
