Carlos wrote a script in response to the above thread. It changes CMYK black, and grayscale black to a swatch called "spot black". It's awesome, but it's only aimed at paths. I've made some adjustments to prevent it from effecting white and unpainted objects. I'm going to need it to work on text and gradients. Right now I am working on text.

I've tried to use the same logic that works on the paths on text, but I'm missing something. Help help.

This is the latest working version, it does not effect text or gradients.

Correct answer elDudereno

it just dawned on me, even though the "layer" property is not listed in the text frame properties, a text frame is still a subset of the "super class" pageItem...so

for page items we have

if (ipath.layer.visible==true && ipath.layer.locked==false && ipath.hidden==false && ipath.locked==false) {

for text, do the same

if (iTxtFrm.layer.visible==true && iTxtFrm.layer.locked==false && iTxtFrm.hidden==false && iTxtFrm.locked==false) {

and forget about meeting the parents


Carlos, you are right about that. I had a logic knot that was preventing it from working on text in groups AND directly on layers at the same time. I ended up using a version that didn't use your fix, even though it was viable.

Here is my final script. Works like a charm. Thanks for all the help.

I doubt you are going to be able to utilize the same syntax for your differing items… Anyhows…

var pi = idoc.pathItems; // Carlos sets variable to a collection…

var ch = idoc.textFrames[0].characters[0]; // Here your variable is to a single character… I doubt this can be tested for locked or hidden…

var ch = idoc.textFrames; // Will give you something to loop thru but you will need to dig deeper still as every character can be different…

Personally I would go for stories when looking thru text…

So...

var ch = idoc.stories[0].textRanges[0].CharacterAttributes;

I'm looking in "Adobe IllustratorCS5 Scripting Reference: JavaScript" on page 226 (textRange) and I'm not seeing locked, hidden, or layers as textRange properties. So I'm guessing I can't test for them for stories either.

My scripting powers mostly consist of looking at an example, deciphering it, and applying what I need to make it work in my instance. Where could I go to find an example of a script that changes the fill and stroke of cmyk and grayscale text that isn't locked or hidden?

I'm pretty ignorant at all of this, so please bear with me.

P.S. If I didn't care if locked or hidden text was changed could I use idoc.textFrames[0].characters[0];  ?

if you don't care checking for Locked or Hidden, then you can skip that, only you'll get an error if a text frame is locked or hidden.

in short you need to loop through all text frames and within each, you have to loop through all characters, once you are at the character level, you can get its characterAttributes property and finally check for fillColor/strokeColor

if you do want to check for lock/hidden then you do that at the textFrame level

...note that textFrames don't have "layer" property...so, it complicates things, to determine if the layer it belongs to is locked or hidden, you have to check its parent...problem is, it can have parent, grand parent, great grand parent...
