tell application "Finder"
  set aSel to selection as alias list
  
if aSel = {} or aSel = "" then return
end tell

–選択した画像をArrayに入れる
set imgList to NSMutableArray’s new()
repeat with i in aSel
  set aPath to POSIX path of i
  
  
–指定ファイルのUTIを取得して、画像(public.image)があれば処理を行う
  
set aRes to (GEMagicKit’s magicForFileAtPath:aPath)
  
set utiList to (aRes’s uniformTypeHierarchy()) as list
  
if "public.image" is in utiList then
    set aNSImage to (NSImage’s alloc()’s initWithContentsOfFile:aPath)
    (
imgList’s addObject:aNSImage)
  end if
end repeat

–KVCで画像の各種情報をまとめて取得
set sizeList to (imgList’s valueForKeyPath:"size") as list –NSSize to list of record conversion
set maxHeight to ((NSArray’s arrayWithArray:sizeList)’s valueForKeyPath:"@max.height") as real
set totalWidth to ((NSArray’s arrayWithArray:sizeList)’s valueForKeyPath:"@sum.width") as real
set totalCount to ((NSArray’s arrayWithArray:sizeList)’s valueForKeyPath:"@count") as integer

–出力画像作成
set tSize to current application’s NSMakeSize((totalWidth + (xGap * totalCount)), maxHeight)
set newImage to NSImage’s alloc()’s initWithSize:tSize

–順次画像を新規画像に上書き
set xOrig to 0
repeat with i in (imgList as list)
  set j to contents of i
  
set curSize to j’s |size|()
  
set aRect to {xOrig, (maxHeight – (curSize’s height())), (curSize’s width()), (curSize’s height())}
  
set newImage to composeImage(newImage, j, aRect) of me
  
set xOrig to (curSize’s width()) + xGap
end repeat

–デスクトップにPNG形式でNSImageをファイル保存
set aDesktopPath to current application’s NSHomeDirectory()’s stringByAppendingString:"/Desktop/"
set savePath to aDesktopPath’s stringByAppendingString:((NSUUID’s UUID()’s UUIDString())’s stringByAppendingString:".png")
set fRes to saveNSImageAtPathAsPNG(newImage, savePath) of me

–2つのNSImageを重ね合わせ合成してNSImageで返す
on composeImage(backImage, composeImage, aTargerRect)
  set newImage to NSImage’s alloc()’s initWithSize:(backImage’s |size|())
  
  
copy aTargerRect to {x1, y1, x2, y2}

backImage’s drawInRect:newImageRect
  
composeImage’s drawInRect:bRect

return newImage
end composeImage

–NSImageを指定パスにPNG形式で保存
on saveNSImageAtPathAsPNG(anImage, outPath)
  set imageRep to anImage’s TIFFRepresentation()
  
set aRawimg to NSBitmapImageRep’s imageRepWithData:imageRep
  
set pathString to NSString’s stringWithString:outPath
  
set newPath to pathString’s stringByExpandingTildeInPath()
  
set myNewImageData to (aRawimg’s representationUsingType:(NSPNGFileType) |properties|:(missing value))
  
set aRes to (myNewImageData’s writeToFile:newPath atomically:true) as boolean
  
return aRes –成功ならtrue、失敗ならfalseが返る
end saveNSImageAtPathAsPNG
