使用 python win32com.client 在 Photoshop 中移動圖層

Question

我一直在使用移動圖層功能，在 python 中編寫 photoshop 腳本。 層最終在其他層集內部而不是在它們之后，等等。

在 Photoshop 的 Javascript 中執行此操作的本機命令是：

layer.move(relativeObject, insertionLocation)

其中 insertionLocation 可以是：

ElementPlacement.INSIDE、ElementPlacement.PLACEATBEGINNING、ElementPlacement.PLACEATEND、ElementPlacement.PLACEBEFORE 或 ElementPlacement.PLACEAFTER

我當前的代碼如下所示：

@staticmethod
def moveLayer(layer, relativeLayer = None, placement = 3):
    if placement == PHAPS.ElementPlacementPLACEATEND:
        layers = PHAPS.app().ActiveDocument.layers
        relativeLayer = layers[len(layers) - 1]
        placement = PHAPS.ElementPlacementPLACEAFTER
    elif placement == PHAPS.ElementPlacementPLACEATBEGINNING:
        relativeLayer = PHAPS.app().ActiveDocument.layers[0]
        placement = PHAPS.ElementPlacementPLACEBEFORE
    layer.Move(relativeLayer, placement)

這是我對常量值的猜測，這顯然是錯誤的：

ElementPlacementPLACEATBEGINNING = 1
ElementPlacementINSIDE = 2
ElementPlacementPLACEBEFORE = 3
ElementPlacementPLACEAFTER = 4
ElementPlacementPLACEATEND = 5

我已經嘗試對這些常量的原始值進行跟蹤，但 Photoshop 可以很好地隱藏它們。 我也嘗試過 Action Manager 代碼，但我發現它有點難以理解。

有誰知道使用 python 在 photoshop 中移動圖層的可靠方法？ 首選 Action Manager 代碼，但不是必需的。

您好，您可以使用這些方法代替 .Move()

def MoveAfter(self, RelativeObject=defaultNamedNotOptArg):
    'Move the PageItem in behind object'
    return self._oleobj_.InvokeTypes(1299596641, LCID, 1, (24, 0), ((9, 1),),RelativeObject
        )

def MoveBefore(self, RelativeObject=defaultNamedNotOptArg):
    'Move the PageItem in front of object'
    return self._oleobj_.InvokeTypes(1299596642, LCID, 1, (24, 0), ((9, 1),),RelativeObject
        )

def MoveToBeginning(self, Container=defaultNamedNotOptArg):
    'Move the PageItem to beginning of container'
    return self._oleobj_.InvokeTypes(1299596646, LCID, 1, (24, 0), ((9, 1),),Container
        )

def MoveToEnd(self, Container=defaultNamedNotOptArg):
    'Move the PageItem to end of container'
    return self._oleobj_.InvokeTypes(1299596645, LCID, 1, (24, 0), ((9, 1),),Container

在哪里：

• RelativeObject = 是相對圖層引用
• Container = 是圖層所在的文檔

例子

from win32com.client import Dispatch

app = Dispatch("Photoshop.Application")
doc = app.Open(r"hereTheProjectPath.psd")
layerRefA = doc.ArtLayers.Add()
layerRefA.MoveToEnd(doc)

layerRefB = doc.ArtLayers.Add()
layerRefB.MoveAfter(layerRefA)

您可以在這里找到所有這些常量值https://github.com/lohriialo/photoshop-scripting-python/blob/master/api_reference/photoshop_2020.py#L243

psPlaceInside                 =0          # from enum PsElementPlacement
psPlaceAtBeginning            =1          # from enum PsElementPlacement
psPlaceAtEnd                  =2          # from enum PsElementPlacement
psPlaceBefore                 =3          # from enum PsElementPlacement
psPlaceAfter                  =4          # from enum PsElementPlacement
