I need a script that groups filled paths by color for paintings by numbers.

[Branimir5FE8]

Hello folks,

In a recent post (https://community.adobe.com/t5/illustrator/script-insert-text-number-in-the-middle-of-visible-bounds...) I was reading on the following matter: the author uploaded a script that groups filled paths by color for paintings by numbers. However, when I tried to apply it to my Illustrator, it didn't work. Instead of showing different numbers in each field, I only get one and the same number.

I would appreciate it if someone could help me with a new, working script. I am also willing to pay for one.

Cheers.

Hi,

Another version of the script. This is handling just pathItems and CMYK colors.  You can test it for simple sneario. This is not final and clean version. Code reference from the same link that you have shared

#target illustrator
    
var doc = app.activeDocument;
function main() {
    var _pageItems = doc.pageItems;
    var _layersCollection = [];
    for (var p = 0; p < _pageItems.length; p++) {
        collectItemsBasedOnColors(_pageItems[p], _layersCollection);
    }
    lays = doc.layers;
    WORK_LAY = lays.add();
    NUM_LAY = lays.add();

    for (var l = 0; l < _layersCollection.length; l++) {
        process(_layersCollection[l].pathItems, false, (l + 1));
    }
}

function process(items, isCompound, _num) {
    var j = 0,
        b, xy, s, p, op;

    for (; j < items.length; j++) {
        // process each pathItem
        op = items[j];
        // add stroke
        if (isCompound) {
            strokeComPath(op);
        } else {
            !op.closed && op.closed = true;
            op.filled = false;
            op.stroked = true;
        };
        b = getCenterBounds(op);
        xy = [b[0] + (b[2] - b[0]) / 2, b[1] + (b[3] - b[1]) / 2];
        s = (
            Math.min(op.height, op.width) < 20 ||
            (op.area && Math.abs(op.area) < 150)
        ) ? 4 : 6; // adjust font size for small area paths.
        add_nums(_num, xy, s);
    }
}

function collectItemsBasedOnColors(myCurrentObject, _layersCollection) {
    var myLayerName = "Unknown";
    if (myCurrentObject.typename == "PathItem") {
        if (myCurrentObject.filled == true) {

        }
        try {

            _layer.name = myLayerName
            myCurrentObject.move(_layer, ElementPlacement.PLACEATBEGINNING);
            _layersCollection.push(_layer);

        },
        xmlstring = '<LiveEffect name="Adobe Offset Path"><Dict data="I jntp 2 R mlim 4 R ofst #offset"/></LiveEffect>'
            .replace('#offset', offset()),
        TIMES = 100; // if shapes are too large, should increase the value.

    if (checkBounds) {
        // check its size only if it needs, because it's too slow
        while (TIMES-- && getMinVisibleSize(p.visibleBounds) > 3) p.applyEffect(xmlstring);
    } else {
        while (TIMES--) p.applyEffect(xmlstring);

main();

Running with attached sample file. Ofcourse more can be done to handle other scenarios.

Sample File

Just updated the code, keep following line

var doc = app.activeDocument;

out the main() function.

[Branimir5FE8]

When I try the updated code the same error pops-up as before. 

[Charu Rajput]

How are you executing the code? Are you using extended toolkit?

[Branimir5FE8]

I load the code directly from illustrator.

[Charu Rajput]

I tried in this way as well, and it is running successfully.

Did you save your code with .jsx extension?

[femkeblanco]

I tried the script on this thread in CS6 and it seems to be working fine for me.  (Thank you, Charu.)

[Charu Rajput]

Thanks femkeblanco  for confirming 🙂

[Branimir5FE8]

I would like the script to show the numbers from 1 to 9 and then to start to show letters: "A,B,C..." and so on. So, for example - 1,2,3,4,5,6,7,8,9,A,B,C,D...etc. 

[Branimir5FE8]

Hello folks,

Can someone of you please help me with a code I need for Illustrator? 

I'm working with paintings by numbers and would like the script to show the numbers from 1 to 9 and then to start to show letters: "A,B,C..." and so on. So, for example - 1,2,3,4,5,6,7,8,9,A,B,C,D...etc. 

Any help would greatly be appreciated.

[femkeblanco]

Replace the line (which is line 100 in the above script)

txt.contents = n;

with these two lines

var x = [0, 1, 2, 3, 4, 5, 6, 7, 8, 9, "A", "B", "C", "D", "E", "F", "G", "H", "I", "J", "K", "L", "M", "N", "O", "P", "Q", "R", "S", "T", "U", "V", "W", "X", "Y", "Z"];
txt.contents = x[n];

The script will fail if you go beyond "Z".

[Branimir5FE8]

Thank you very nice.

[lloyd888]

hi there please could I have the link to download this script also. it would be much appreciated

[CarlosCanto]

there's no download link, the script is posted here in response #1 by Charu. You have to copy/paste in a blank text file and save it with any name, but change the extension to jsx

[lcat28183736g6qy]

Hello!

when one shape is inside another, the script puts the number into the inner shape three times.

How to fix it?

[jesusr7957719]

Hi all folks,

I get the following error, does anyone knows how can I fix it?

Error 1200: an illustrator error occurred: 1246458189 ('MRAP')

Line:128

-> while (TIMES--) p.applyEffect(xmlstring);

Thank you in advance 

[Inventsable]

An alternative I made for RGB colorspace is here

[lcat28183736g6qy]

It's not working with compound paths 😞

[Inventsable]

It was never intended to. Compound Paths can have multiple fills within their children paths, and you wouldn't be able to group those children paths with other paths without breaking the compound.

[defaultpqrozb79d4vk]

Hello. What can be done in this script to put more than one number depending on the area of the object?

For example like this!
