[Script] Resizing multiple objects propotrionally

[polotrobo]

Hello everyone,
Here is my problem, I want to resize multiple objects with a script by selecting the size (in mm) that I want. I already have one script but this script don't resize proportionally. 

var centerObjects = false;

function main() {

    var item, center_point;

    var toPixels = function (v) {

        var units = {

            'in': 72,

            'mm': 2.8346455078125,

            'px': 1,

            'pt': 1,

        }, re = /(\d*[.]*\d+)(mm|in|ft|cm|px|pt)/i, m, u, rep;

        //derivitave

        units['cm'] = units['mm'] * 10;

        units['ft'] = units['in'] * 12;

        while (m = v.match(re)) {

            u = m[2].toLowerCase();

            if (units[u]) {

                rep = (m[1] * units[u]);

                v = v.replace(re, rep);

            }

        }

        return v;

    }

    var trace = function (m) { alert(m) };

    if (activeDocument == null) { trace("Pas de document ouvert trouvé. Veuillez s'il vous plaît ouvrir un document."); return; }

    if (activeDocument.selection.length == 0) { trace("Aucune sélection... 😞", "Veuillez sélectionner un pictogramme."); return; }

    var i = prompt("Quelles dimensions voulez-vous modifier ?", "width,height");

    if (i === null) { return false; }

    var v = prompt("Veuillez entrer les nouvelles dimensions du pictogramme", "5mm,5mm");

    v = toPixels(v);

    // here's where we walk through all objects.

    var assign = function (i, v) {

        for (var x = 0; x < activeDocument.selection.length; x++) {

            item = activeDocument.selection[x];

            //get top and left width and height values

            center_point = [item.top - (item.height / 2), item.left + (item.width / 2)];

            item[i] = eval(v);

            //redraw();

            if (centerObjects) {

                //center_point = [item.top+(item.height/2),item.left+(item.width/2)];

                item.top = center_point[0] + (item.height / 2);

                item.left = center_point[1] - (item.width / 2);

            }

        };

    }

    if (i.indexOf(',') !== -1) { i = i.split(','); }

    //split if a list, but not if function is found.

    if (v.indexOf(',') !== -1) { v = v.split(','); }

    if (typeof i !== "string") {

        for (var len = i.length, c = 0; c < len; c++) {

            assign(i[c], typeof v !== 'string' ? v[c] : v);

        }

    } else {

        assign(i, v);

    }

    redraw();

    return true;

}

main();

After runing the script:

As you can see it don't resize them proportionally..

Thank you,

Hi,

Try following

var centerObjects = false;
function main() {
    var item, center_point;
    var toPixels = function (v) {

        var units = {
            'in': 72,
            'mm': 2.8346455078125,
            'px': 1,
            'pt': 1,
        }, re = /(\d*[.]*\d+)(mm|in|ft|cm|px|pt)/i, m, u, rep;
        //derivitave
        units['cm'] = units['mm'] * 10;
        units['ft'] = units['in'] * 12;

        while (m = v.match(re)) {
            u = m[2].toLowerCase();
            if (units[u]) {
                rep = (m[1] * units[u]);
                v = v.replace(re, rep);
            }
        }
        return v;
    }

    var trace = function (m) { alert(m) };
    if (activeDocument == null) { trace("Pas de document ouvert trouvé. Veuillez s'il vous plaît ouvrir un document."); return; }
    if (activeDocument.selection.length == 0) { trace("Aucune sélection... 😞", "Veuillez sélectionner un pictogramme."); return; }
    var i = prompt("Quelles dimensions voulez-vous modifier ?", "width,height");
    if (i === null) { return false; }
    var v = prompt("Veuillez entrer les nouvelles dimensions du pictogramme", "5mm,5mm");
    v = toPixels(v);
    v = v.split(',');
    for (var x = 0; x < activeDocument.selection.length; x++) {
        item = activeDocument.selection[x];
        var scaleX = v[0] / item.width;
        var scaleY = v[1] / item.height;
        var finalScaleFactor = scaleX > scaleY ? scaleY : scaleX;
        item.resize(finalScaleFactor * 100, finalScaleFactor * 100, true);
    }
}
main();

Hi @Charu Rajput 

Thank you so much it's perfect !!

Best regards

You can also try my free "ResizeToSize" script to resize objects with different settings. Units are taken from the document settings. Uniform - proportional scaling. You can choose which side to calculate. Change the size by a delta. https://github.com/creold/illustrator-scripts/blob/master/md/Item.md#resizetosize

Thank you @Sergey Osokin it's a very useful script 🙂

Best regards
