Hi Leonard,
I had a newer post this morning with what I came to after some work. Please
look at that.
Further to that let's suppose: a document under examination can be using any
(valid) colorspace, or a combination of. If so, I have to get this information
on a page by page base and have the program take some action depending on that
information.
To that I also need any named colors (like Pantone) used besides the normal
base colors. This is what I refered originally -by name - I only need the name
of the color used. I don't have to know the chromatic values of any color used
on the other hand.

Re: [iText-questions] How to get a reference by name of all the colors in a
page?
I guess I don't understand this. If I have a color specified as a combination
fo Cyan and Magenta - what is the "name" of that color? Or what about Red +
Green?
What about colorspaces like LAB or ICCBased?
What do you want to do with DeviceN?

Hi Leonard,Thanks for comming back. What I need is the sum of all colors used
in the page and their names. 1. Is CMYK colorspace. Number is 4, the names
"Cyan" "Magenta" Yellow" Black".2. Is RGB colorspace. Number is 3, names are
"Red" "Green" "Blue".3. Is CMYK plus Spot. Number is 4 + ? , names are ("C" "M"
"Y" "K") + ?. Does this makes sense?Thanks

Do you want to know the colorspaces (RGB vs CMYK vs Spot) _OR_ are you actually
looking at specific color values ([0 0 1], [1 1 0 0], etc.)??

Hi all, I 've searched the forum and found a similar question posted a long
time ago but in different context as I understand it, so please excuse me if a
raise the same subject.What I have to do is: While a pdf document is open and a
loop is counting to end of number_of_pages, I have to run a certain action and
I need to know the total number of colors (RGB and/or CMYK plus Spot if used)
in this page. This number defined as the sum of colors used by all elements on
the page, whether textual, graphic or images. Also I need to know these colors
by name reference (as a string list). The sequence is repeating for each page
and program flow depends on this information.Is it possible through
PageResources class? Or any other procedural way? Thanks in advance
