在gimp 2.0下，script-fu脚本不能加载图像

Question

我试着用gimp 2.8编写这个脚本。

我在过程浏览器中看不到script-fu-register )。

我试着用RUN-INTERACTIVE和RUN-RUN INTERACTIVE来运行...此脚本：

 (define (script-fu-cut-height filename outputfilename myheight)
 (let* (
  (img (myimage (gimp-file-load RUN-INTERACTIVE filename filename)))
  (imagewidth (myimage (gimp-image-width img)))
  (imageheight (myimage (gimp-image-height img)))
  (width (- imagewidth (+ right left)))
  (height (- myheight (+ top bottom)))
  )
  (gimp-image-crop img width height left top)
  (gimp-png-save RUN-INTERACTIVE
    img
    (myimage (gimp-image-active-drawable img))
    outputfilename
    outputfilename)
 (gimp-image-delete img)
 ))

 (script-fu-register "script-fu-cut-height"
 "www.free-tutorials.org : script-fu"
 "Cut an image by height and let width default"
 "test"
 "www.free-tutorials.org"
 "Jul 2013"
 "RGB* GRAY*"
 SF-STRING "Filename" ""
 SF-STRING "OutputFilename" ""
 SF-VALUE "TopEdge" "0"
 SF-VALUE "RightEdge" "0"
 SF-VALUE "BottomEdge" "0"
 SF-VALUE "LeftEdge" "0"
 )
 script-fu-cut-height()

我使用下面的代码来运行它：

$ gimp -i -c -b "(script-fu-cut-height \"test-script-fu.png\" \"out-script-fu-output.png\" 85)" -b  "(gimp-quit 0)"

用户主文件夹中的图像。

我得到的错误是：

~$ gimp -i -c -b "(script-fu-cut-height \"test-script-fu.png\" \"out-script-fu-       output.png\" 85)" -b  "(gimp-quit 0)"

错误显示为“未绑定变量: myimage”。这告诉您，您正在引用一个名为"myimage“的变量/函数，但您从未定义过该变量，因此它不知道"myimage”代表什么。

你知道"myimage“应该代表什么吗？你是不是抄袭了别人的剧本？

函数gimp-file-load返回一个包含您打开的图像的列表。您需要使用"car“函数从该列表中提取第一个条目，以便将其存储在"img”变量中。所以不是(img (myimage (gimp-file-load RUN-INTERACTIVE filename filename )，而是(img (car (gimp-file-load RUN-INTERACTIVE filename filename)

此外，我认为您可能希望使用RUN-NONINTERACTIVE。

同样，我认为您将需要更改(my image ...)的其他实例。成为(汽车……)而不是。
