URGENT: My boss wants me to do in Photoshop...

[Benedikt]

Please Photoshop experts, help me out with this problem:

*) We need Adobe Photoshop for a print quality analysis:
Adobe Photohop features a histrogram function: But how do I get the values of this histogram function into a text data file? I write down the values manually, but this costs a LOT of time, since we have to do many measurements....

Please I beg you, help me out, show me some alternative software or give me the missing hint....

Greetings and very thanks for your help!

*bump* me too....

Well exactly I need the following values (I select an image area --> then I choose "histogram"):

*) standard deviation
*) average value
*) centralworth

I don't know if this is translated correctly, but all these values are returned by the "histogram" function --> Now I need to store them in a text file!

Thanks for your help in advance....

There is a 'tryout' download for Photoshop if you're that desperate, it's 162.4MB.

Download page link.

Ohh I see. In that case, I don't have a clue! Read the help.

Check out ImageJ (bottom link on the page) from the National Institutes of Health (NIH) http://rsb.info.nih.gov/nih-image/

Check out the Analyze Menu (Set Measurements, and then Measure) - results can be saved. Hope that helps.

Hi there,

Check out ImageJ (bottom link on the page) from the National Institutes of Health (NIH)

Well first, thanks very much, it's a very good first aproach, this little Java Program helps me a lot.

But there are some problems which are still unsolved:

• ImageJ features histogram data output, but only for the luminance channel!
  It's not automated, so I still have to do : open image, histogram, output manually

The best would be a DLL usable in MS Visual C++ or a Photoshop plugin which features builtin histogram routines!

If you can help me with this, this would be very kind of you....

Thanks for your help in advance...
