illustrator插件--画板功能开发--旋转画板--js脚本开发

1.算法程序

  illustrator是矢量编辑软件，画板是绘制处理的重要容器，开发一个旋转画板功能，源代码如下所示：

app.userInteractionLevel = UserInteractionLevel.DONTDISPLAYALERTS;
var scriptName = "旋转画板和对象";
var scriptVersion = "1.2";
try {
    if (documents.length > 0) {
        var doc = app.activeDocument;
        var currArt = doc.artboards[doc.artboards.getActiveArtboardIndex()];
        var currArtNum = doc.artboards.getActiveArtboardIndex() + 1;
        var lockedItems = new Array();
        var hiddenItems = new Array();
        var dlg = new Window("dialog", scriptName + " ver." + scriptVersion + "", undefined);
        dlg.orientation = "column";
        dlg.alignChildren = ["fill", "fill"];
        var slctTarget = dlg.add("panel", undefined, "旋转范围");
        slctTarget.orientation = "column";
        slctTarget.alignChildren = "left";
        slctTarget.margins = 20;
        var currArtRadio = slctTarget.add("radiobutton", undefined, "当前画板 #" + currArtNum);
        var allArtRadio = slctTarget.add("radiobutton", undefined, "所有画板 " + doc.artboards.length + " Artboards");
        currArtRadio.value = true;
        var slctAngle = dlg.add("panel", undefined, "旋转角度:");
        slctAngle.orientation = "row";
        slctAngle.alignChildren = ["fill", "fill"];
        slctAngle.margins = 20;
        var cwAngle = slctAngle.add("radiobutton", undefined, "顺时针90度");
        var ccwAngle = slctAngle.add("radiobutton", undefined, "逆时针90度");
        cwAngle.value = true;
        var btns = dlg.add("group");
        btns.alignChildren = ["fill", "fill"];
        btns.margins = [0, 10, 0, 0];
        var cancel = btns.add("button", undefined, "取消", {
            name: "cancel"
        });
        cancel.helpTip = "Press Esc to Close";
        cancel.onClick = function() {
            dlg.close();
        };
        var ok = btns.add("button", undefined, "确定", {
            name: "ok"
        });
        ok.helpTip = "Press Enter to Run";
        ok.active = true;
        ok.onClick = okClick;
        selection = null;
        app.redraw();
        dlg.center();
        dlg.show();

        function okClick() {
            saveItemsState();
            if (currArtRadio.value == true) {
                rotateArt(currArt);
            } else {
                for (var i = 0; i
