According to
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=656942
It seems that the output of identity change if -v flags was given see original thread.
Please fix or at least document under man page (least surprise).
Thanks

The user should check the image type for a reliable method of determining the type of image. For rock48.png we get the expected results:
- -> identify -verbose rock48.png | more
Image: rock48.png
Format: PNG (Portable Network Graphics)
Class: DirectClass
Geometry: 20x20+0+0
Resolution: 72x72
Print size: 0.277778x0.277778
Units: Undefined
Type: PaletteMatte
Endianess: Undefined
Colorspace: sRGB
Depth: 8-bit
...

The problem is the difference between -verbose class and without verbose. Least surprise will direct to be the same.

It looks like a problem with the PNG coder. We'll pass the problem onto the PNG developer and hopefully we'll get a patch in a day or two. Thanks.

I have checked in a fix to SVN revision 7017 that makes the non-verbose identify output agree with the verbose (correct) output.
