Color Space information from image files (PSD, PSB, AI)

[Stephen Marsh]

Agreed Phil, I was just typing out my justification for disagreement! :]

Thank you Phil! This is sweet, Adobe don't even offer an out of the box solution for this in Adobe Bridge.

A small point of disagreement, I personally believe that the result of AI9_ColorMode: 1 should be indicated as:

Code Select Expand

AI Color Model : RGB

Rather than:

Code Select Expand

AI Color Model : sRGB

As the colour mode/model (RGB) is independent of the specific colour space (sRGB, Adobe RGB 1988, ProPhoto RGB etc). My test file had no ICC profile, so it should not be automatically assumed to be sRGB, it is just "mystery meat" RGB.

Just as AI9_ColorMode: 2 is simply shown as a simple colour mode/model of "CMYK" rather than as a specific colour space name.

Yes.  See my previous post.  I'll fix this for 10.94

...for the fun of it:

NERD!

heh, just kidding of course 

[Phil Harvey]

NERD!

Caught red handed.

[Stephen Marsh]

Haha:

-if '$AIColorModel eq "RGB"'
-if '$AIColorModel =~ /RGB/'

The great thing about ExifTool (Perl) is it's ability to confound uninitiated users with the flexibility of it's command line syntax!

We aim to please.

The two are different though; the first will only match the exact string RGB, the latter any string with RGB in it. So the latter will (also) match sRGB while the first won't

Must... confuse... moar!

-if "index($AIColorModel,'RGB)==0"

It will only match if the tag starts with "RGB", so it won't match "sRGB", but it would match if something followed "RGB".

Thanks Hayo, just when I thought that I knew what was going on! :]

This is really useful stuff!

It will only match if the tag starts with "RGB", so it won't match "sRGB", but it would match if something followed "RGB".

So it is the equivalent of a regex of:

^RGB

or do you mean:

\b^RGB\b

[StarGeek]

More like ^RGB but only because I checked to see if it was equal to 0.  From the Perl docs:

"The index function searches for one string within another, but without the wildcard-like behavior of a full regular-expression pattern match. It returns the position of the first occurrence of SUBSTR in STR..."

By changing it to >=0 it would become the equivalent of /RGB/.  Adding the word boundries \b would be more complicated than it's worth for index.
