我尝试使用 gimp 2.8 制作这个脚本。

我在过程浏览器中没有看到 script-fu-register）。

我尝试使用 RUN-INTERACTIVE 和 RUN-NONINTERACTIVE 运行...这个脚本：

 (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()

我用它来运行它：

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

它在用户主文件夹上的图像。

我得到的错误：

~$ 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“未绑定变量：myimage”。这告诉您您指的是一个名为“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？你是从别人的剧本里抄来的吗？

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，以便将其存储在您的“img”变量中。因此，而不是 (img (myimage (gimp-file-load RUN-INTERACTIVE filename filename))) 它应该说 (img (car (gimp-file-load RUN-INTERACTIVE filename filename)))

另外，我认为您可能想改用 RUN-NONINTERACTIVE 。

同样，我认为您需要将 (my image ...) 的其他实例更改为 (car ...) 。
