Photoshop CC Javascript - 翻转图层/图像

Question

我需要能够垂直或水平翻转图像/活动层。

纵观 Adobe Photoshop CC Javascript Reference，activelayer/object 似乎没有翻转方法。

doc.flipCanvas(Direction.VERTICAL)

确实有效，但显然会垂直翻转整个文档，因为我只想在活动层上这样做

我可以在 invert() 方法中看到它确实提到了：

inverts the selection (deselects the selection and selects the rest of the layer or document). Tip. To flip the selection shape, see rotate

上面写着：

rotate (angle [, anchor]) -

Rotates the selection by the specified amount around the specified anchor

我已经像其他地方一样使用旋转方法，但看不出如何通过它翻转图像？

obj.rotate( rotation,  AnchorPosition.TOPLEFT );

Answer 1

ArtLayer没有翻转方法，可以用.resize代替：

Resizes the layer to the specified dimensions (as a percentage of its current size) and places it in the specified position.

activeDocument.activeLayer.resize(-100,undefined); //will flip layer horizontally
activeDocument.activeLayer.resize(undefined,-100); //will flip layer vertically

（锚点还有第三个参数）

Answer 2

var idFlip = charIDToTypeID( "Flip" );
var desc16024 = new ActionDescriptor();
var idnull = charIDToTypeID( "null" );
var ref2273 = new ActionReference();
var idLyr = charIDToTypeID( "Lyr " );
var idOrdn = charIDToTypeID( "Ordn" );
var idTrgt = charIDToTypeID( "Trgt" );
ref2273.putEnumerated( idLyr, idOrdn, idTrgt );
desc16024.putReference( idnull, ref2273 );
var idAxis = charIDToTypeID( "Axis" );
var idOrnt = charIDToTypeID( "Ornt" );
var idHrzn = charIDToTypeID( "Hrzn" );
desc16024.putEnumerated( idAxis, idOrnt, idHrzn );
executeAction( idFlip, desc16024, DialogModes.NO );

将水平翻转一层。
