pngcrush command line do nothing for -text option

Question

From this page http://en.wikipedia.org/wiki/Pngcrush I use this command line in Mac OS X Terminal

pngcrush -rem text InputFile.png OutputFile.png

It's work ! But this :

pngcrush -text b "Software" "pngcrush" image1.png image2.png

do nothing and output like launching pngcrush without option.

What's wrong ?

Answer 1

The current version of pngcrush (version 1.7.67) should do what you want. Some bugs with text insertion were fixed in pngcrush-1.7.29 and 1.7.67.
