Is there a way to list image dimensions for .png files?

[rickgut2016]

Is there a way to list image dimensions for .png files? I'm using this code, and I'm only getting the file dimensions of .jpg, and .gif files.

identify.exe -format "%f %w %y" *.*

I'm getting this error for .png files:
identify.exe: improper image header `ccp-pd-080-90.png' @ error/png.c/ReadPNGImage/3921.

Any help would be greatly appreciated! Thanks ya'll!

What is your IM version and version of libpng?

You can get them from

Code: Select all

convert -version

Code: Select all

convert -list format

See http://www.imagemagick.org/script/escape.php

"%y" is not the height, but the resolution (dpi) in the vertical dimension. If you want the height, use "%h"

improper image header `ccp-pd-080-90.png'

It sounds like a problem with that file. Please upload to somewhere like dropbox.com and paste the URL here.

Here is my version info:

and

I will use %h, thank you! Please let me know if I need a different version of anything. Thanks so much! This is a work project, so it would be sweet if I can get it working. Basically I need to list the dimensions (width, height) of 28 thousand files.. Looks like the files are .jpg, .gif, and .png.

See snibgo's comment above about providing your png input file.

Update: It looks like those .png files are corrupt. I should have checked that fist.. Thanks for the help all. I learned a few things
