illustrator插件-常用功能开发-随机填色-js脚本开发-AI插件

illustrator是矢量编辑软件，画板是绘制处理的重要容器，在印刷方面的一个重要功能就是颜色处理，开发一个随机填充颜色功能，以下功能仅用于学习交流，请勿用于非法用途和商业用途，源代码如下所示：

len = app.activeDocument.selection.length;gradAlert = 0;strokes = false;if (len == 0) {    alert("Please select one or more objects. Grouped objects will not be affected.");} else {    ob = app.activeDocument.selection;    var line1 = "1. 要随机填充色，输入1-100的数值（数值越大，明度越小） ";    var line2 = "2.要随机轮廓色，输入1-100的数值并以英文“S”结尾（数值越大，明度越大） ";    var line3 = "3.要随机不透明度，输入1-100的最小值和最大值，如30,100 ";    var data = prompt(line1 + line2 + line3, "");    if (data == null || data.length == 0) {    } else {        if (data.indexOf(",") > 0) {            action = data.split(",");        } else {            action = data.split(" ");        }        if (action[action.length - 1] == "s") {            action.length = action.length - 1;            strokes = true;        }        if (action[action.length - 1].charAt(action[action.length - 1].length - 1) == "s") {            action[action.length - 1] = action[action.length - 1].substr(0, action[action.length - 1].length - 1);            strokes = true;        }        var baseVal = action[0];        for (var j = 0; j < len; j += 1) {            if (isNumber(action[0]) && isNumber(action[1]) && action.length == 2) {                calcNum = (action[0] * 1) + (Math.random(1) * (action[1] - action[0]));                ob[j].opacity = setLegal(calcNum);            } else if (isNumber(action[0], 255) && action.length == 1) {                if (app.activeDocument.documentColorSpace == "DocumentColorSpace.RGB") {                    action[0] = Math.round(baseVal * 2.55);                }                if (strokes == false) {                    if (ob[j].filled == true) {                        setColor(ob[j].fillColor, setLegal(action[0], 255));                    }                } else {                    if (ob[j].stroked == true) {                        setColor(ob[j].strokeColor, setLegal(action[0], 255));                    }                }            } else {                j = len;                error(action[0]);            }        }    }}function error(val) {    alert(val + " 数值与脚本不符，应控制在1-100之间！");}function isNumber(num, max) {    if (max == undefined) {        max = 100;    }    if (num >= 0 && num <= max) {        return true;    }    return false;}function setLegal(num, max) {    if (max == undefined) {        max = 100;    }    if (num < 0) {        return -num % max;    } else if (num > max) {        return max - (num % max);    } else {        return num;    }}function setColor(obj, dev) {    var d = Math.round(Math.random(1) * dev);    if (obj == undefined) {    } else if (obj.typename == "RGBColor") {        d = Math.round(Math.random(1) * dev);        var r = obj.red;        obj.red = setLegal((r - dev) + (d * 2), 255);        d = Math.round(Math.random(1) * dev);        var g = obj.green;        obj.green = setLegal((g - dev) + (d * 2), 255);        d = Math.round(Math.random(1) * dev);        var b = obj.blue;        obj.blue = setLegal((b - dev) + (d * 2), 255);    } else if (obj.typename == "SpotColor") {        var d = Math.round(Math.random(1) * dev);        var t = obj.tint;        obj.tint = setLegal((t - dev) + (d * 2), 100);    } else if (obj.typename == "GrayColor") {        var d = Math.round(Math.random(1) * dev);        var t = obj.gray;        obj.gray = setLegal((t - dev) + (d * 2), 100);    } else if (obj.typename == "CMYKColor") {        d = Math.round(Math.random(1) * dev);        var c = obj.cyan;        obj.cyan = setLegal((c - dev) + (d * 2), 100);        d = Math.round(Math.random(1) * dev);        var m = obj.magenta;        obj.magenta = setLegal((m - dev) + (d * 2), 100);        d = Math.round(Math.random(1) * dev);        var y = obj.yellow;        obj.yellow = setLegal((y - dev) + (d * 2), 100);        d = Math.round(Math.random(1) * dev);        var k = obj.black;        obj.black = setLegal((k - dev) + (d * 2), 100);    } else {        if (gradAlert != 1 && obj.typename == "PatternColor" || obj.typename == "GradientColor") {            gradAlert = 1;            alert("Patterns and Gradients will not be transformed.");        }    }}

  合理的脚本代码可以有效地提高工作效率，减少重复劳动。
