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标注纵尺寸，开发一个标注纵尺寸功能，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：

doc = app.activeDocument;
theSelect = doc.selection;
for (var i = 0; i < theSelect.length; i += 1) {
    x = theSelect[i].left;
    y = theSelect[i].top;
    w = theSelect[i].width;
    h = theSelect[i].height;
    s = 30;
    asize = 20;
    if (h < 50 || w < 50) {
        asize = 5;
    }
    tsize = 36;
    if (h < 60 || w < 60) {
        tsize = 12;
    }
    redColor = new CMYKColor();
    redColor.black = 1;
    redColor.cyan = 1;
    redColor.magenta = 100;
    redColor.yellow = 100;
    var g1 = doc.groupItems.add();
    var line1 = g1.pathItems.add();
    line1.setEntirePath(new Array(new Array(x - s, y), new Array(x - s, y - h)));
    line1.strokeColor = redColor;
    var line1 = g1.pathItems.add();
    line1.setEntirePath(new Array(new Array((x - s) - (s / 2), y), new Array(x - (s / 2), y)));
    line1.strokeColor = redColor;
    var line1 = g1.pathItems.add();
    line1.setEntirePath(new Array(new Array((x - s) - (s / 2), y - h), new Array(x - (s / 2), y - h)));
    line1.strokeColor = redColor;
    var ar1 = g1.pathItems.add();
    ar1.setEntirePath(new Array(new Array(x - s, y), new Array((x - s) - (asize / 2), y - asize), new Array((x - s) + (asize / 2), y - asize)));
    ar1.strokeColor = NoColor;
    ar1.fillColor = redColor;
    ar1.closed = true;
    var ar1 = g1.pathItems.add();
    ar1.setEntirePath(new Array(new Array(x - s, y - h), new Array((x - s) - (asize / 2), (y - h) + asize), new Array((x - s) + (asize / 2), (y - h) + asize)));
    ar1.strokeColor = NoColor;
    ar1.fillColor = redColor;
    ar1.closed = true;
    var t1 = g1.textFrames.add();
    t1.contents = (Math.round(h * 0.35277778 * 1000) / 1000) + " mm";
    t1.textRange.characterAttributes.size = tsize;
    t1.textRange.characterAttributes.fillColor = redColor;
    t1.left = ((x - s) - s) - (t1.width / 2);
    t1.top = (y - (h / 2)) + (t1.height / 2);
    t1.rotate(90);
}
