javascript - 通过 javascript 在 Illustrator 中将图稿与画板对齐

Question

我正在尝试通过 javascript 将 illustrator 中的对象定位到艺术板左侧的底部。我可以使用 javascript 访问该对象并对其执行功能，如“旋转”

if ( app.documents.length > 0) {
    doc = app.activeDocument;
}


   function traceImage(doc) {

         doc.pageItems[0].rotate (30);


}

traceImage(doc);

但我无法找到一种简单的方法来定位/对齐画板底部/左侧的“pageItems[0]”。除了计算它的当前距离然后移动它之外，还有更简单的方法吗？谢谢。

同样，如果您希望将项目居中放置在画板上，您需要以不同方式处理高度和宽度。

if ( app.documents.length > 0) {
    doc = app.activeDocument;

    // Get the active Artboard index
    var activeAB = doc.artboards[doc.artboards.getActiveArtboardIndex()];

    // Get the right most X point of the Artboard
    // artboardX + artboardWidth
    var artboardRight = activeAB.artboardRect[0] + activeAB.artboardRect[2];
    // Get the bottom most Y point of the Artboard
    // artboardY + artboardHeight
    var artboardBottom = activeAB.artboardRect[1] + activeAB.artboardRect[3];
   
    // The page item you want to move. Reference it how you will. This just
    // obviously grabs the first pageItem in the document.
    var myPageItem = doc.pageItems[0];

    // Here is where the magic happens. Set the position of the item.
    // [0,0] would be at the top left, so we have to compensate for the    artboard
    // height and width. We add item's height then split it for the vertical
    // offset, or we'd  end up BELOW the artboard.
    // Then we subtract the item's width and split the difference to center the
    // item horizontally.
    var horziontalCenterPosition = (artboardRight - myPageItem.width)/2;
    var verticalCenterPosition = (artboardBottom + myPageItem.height)/2;

    myPageItem.position = [horziontalCenterPosition, verticalCenterPosition];
}
