Hello,

I am using ImageMagick 6.7.2-7 2016-05-09 on CentOS6.

I need to get the colorspace listed within the results of

Code: Select all

identify -verbose 40449545.converted.11.jpg

The following is supposed to do it:

Code: Select all

identify -format %[colorspace] 40449545.converted.11.jpg

But it doesn't return what I see in the first identify command. For instance:

Code: Select all

[root@svr-h002607 tmp]# identify -format %[colorspace] 40449545.converted.11.jpg
Gray
[root@svr-h002607 tmp]# identify -verbose 40449545.converted.11.jpg | grep Colorsp
  Colorspace: RGB

Why is there a discrepancy?

Thank you!

P.S. I'm not very familiar with IM or image manipulation in general, this is just something I need to do as part of a script.

That's a very old version, back in the days when IM thought gray-only images were linear. I suggest you upgrade.

Okay thank you.

Unfortunately this is a production environment where upgrading software is out of the question.
Pretty shocking that IM made it all the way to this version with something so fundamental working incorrectly.

Cheers

Which value do you think is correct? Perhaps you can post your image to some place such as dropbox.com and we can see what is going on. It is possible IM was undergoing some changes at that release or perhaps a bug in that release. The colorspace could be RGB, but the type could be grayscale if all channels are the same. Not sure what IM was doing at such an old version of IM.

Also I am not sure that %[colorspace] was properly implemented until after your release. From the changelog:

2012-08-16 6.7.9-1 Cristy <quetzlzacatenango@image...>
...
Identify command now reports the image colorspace for non-verbose results.
