Question

如下图所示，

如何在 Photoshop 脚本中获取宽度、高度和旋转角度。

Get Layer width, height and rotation angle

Answer 1

你需要两件事。首先是一个将图层作为选区抓取的函数。其次，您需要获得图层边界 - 您可以从中计算出高度和宽度。

var currentLayer = app.activeDocument.activeLayer.name;
var currentLayerSelection = layer_selection();
var lb = get_selection_bounds();

alert(currentLayer + " layer bounds:\n" + lb[0] + ", " + lb[1] + ", " + lb[2] + ", " + lb[3]);




// function GET SELECTION BOUNDS ()
// ----------------------------------------------------------------
function get_selection_bounds()
{
  try
  {
    var x = parseFloat(app.activeDocument.selection.bounds[0]);
    var y = parseFloat(app.activeDocument.selection.bounds[1]);
    var x1 = parseFloat(app.activeDocument.selection.bounds[2]);
    var y1 = parseFloat(app.activeDocument.selection.bounds[3]);

    var selW = parseFloat(x1-x);
    var selH = parseFloat(y1-y);

    // return the results as an array
    return [x, y, x1, y1];
  }
  catch(e)
  {
    alert("Oops " + e)
  }
}

function layer_selection()
{
  var id1268 = charIDToTypeID( "setd" );
  var desc307 = new ActionDescriptor();
  var id1269 = charIDToTypeID( "null" );
  var ref257 = new ActionReference();
  var id1270 = charIDToTypeID( "Chnl" );
  var id1271 = charIDToTypeID( "fsel" );
  ref257.putProperty( id1270, id1271 );
  desc307.putReference( id1269, ref257 );
  var id1272 = charIDToTypeID( "T   " );
  var ref258 = new ActionReference();
  var id1273 = charIDToTypeID( "Chnl" );
  var id1274 = charIDToTypeID( "Chnl" );
  var id1275 = charIDToTypeID( "Trsp" );
  ref258.putEnumerated( id1273, id1274, id1275 );
  desc307.putReference( id1272, ref258 );
  executeAction( id1268, desc307, DialogModes.NO )

}

您可以计算出高度和宽度：

var layerWidth  = lb[2] - lb[0]; 
var layerHeight = lb[3] - lb[1]; 
alert("Width, height: " + layerWidth + ", " + layerHeight);

至于角度..让我们说自己做要容易得多。

使用标尺工具 - 然后 Photoshop 将计算出角度。查看“图像”>“图像旋转”>“任意”，它会显示旋转画布以使其恢复水平的角度。
