MaxScript通过Ole操作Phtoshop的范例，将几张图按图层合并为psd

也是在qq群遇到的网友的问题，，实际上如果只是合并成psd也可以找.net的库来做，不过大部分库都是只能读不能写，是因为psd的授权问题。此外也为了普及一下ole这个老古董。不过这段代码只操作cs6通过，其他photoshop的版本可能有改动。

Fn CombineTextureToPSD inputSourceArray inputSavePsdFile photoshopExit:true =
(
    if inputSourceArray.Count > 1 do 
    (
        Global PhotoshopApplication
        PhotoshopApplication = createOLEObject "Photoshop.Application"
        for tempFileName in  inputSourceArray do
        (
            PhotoshopApplication.Load tempFileName
        )
        
        for i =2 to inputSourceArray.Count do
        (
            PhotoshopApplication.ActiveDocument = PhotoshopApplication.Documents i
            PhotoshopApplication.ActiveDocument.Selection.SelectAll()
            PhotoshopApplication.ActiveDocument.Selection.Copy()
            PhotoshopApplication.ActiveDocument = PhotoshopApplication.Documents 1
            PhotoshopApplication.ActiveDocument.Paste()
        )
        PhotoshopApplication.ActiveDocument.SaveAs inputSavePsdFile
        /* 早期版本可能是 PhotoshopApplication.Documents.Length */
        while PhotoshopApplication.Documents.Count > 0 do    PhotoshopApplication.ActiveDocument.Close 2
        if photoshopExit == True do
        (
            PhotoshopApplication.Quit()
            ReleaseOLEObject PhotoshopApplication
            PhotoshopApplication = undefined 
            GC()
        )
    )
)
