illustrator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] = und(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 = und(Math.random(1) * dev);if (obj == undefined) {} else if (pename == "RGBColor") {d = und(Math.random(1) * dev);var r = d = setLegal((r - dev) + (d * 2), 255);d = und(Math.random(1) * dev);var g = ; = setLegal((g - dev) + (d * 2), 255);d = und(Math.random(1) * dev);var b = obj.blue;obj.blue = setLegal((b - dev) + (d * 2), 255);} else if (pename == "SpotColor") {var d = und(Math.random(1) * dev);var t = obj.tint;obj.tint = setLegal((t - dev) + (d * 2), 100);} else if (pename == "GrayColor") {var d = und(Math.random(1) * dev);var t = ay = setLegal((t - dev) + (d * 2), 100);} else if (pename == "CMYKColor") {d = und(Math.random(1) * dev);var c = an = setLegal((c - dev) + (d * 2), 100);d = und(Math.random(1) * dev);var m = obj.magenta;obj.magenta = setLegal((m - dev) + (d * 2), 100);d = und(Math.random(1) * dev);var y = llow = setLegal((y - dev) + (d * 2), 100);d = und(Math.random(1) * dev);var k = obj.black;obj.black = setLegal((k - dev) + (d * 2), 100);} else {if (gradAlert != 1 && pename == "PatternColor" || pename == "GradientColor") {gradAlert = 1;alert("Patterns and Gradients will not be transformed.");}}
}

  合理的脚本代码可以有效的提高工作效率，减少重复劳动。
