Question

我尝试使用gimp 2.8来编写这个脚本。

我在程序浏览器中看不到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)"

用户主文件夹中的图像。

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“unbound variable：myimage”。这告诉你，你指的是一个名为“myimage”的变量/函数，但你从未定义过该变量，所以它不知道“myimage”代表什么。

你知道“myimage”应该代表什么吗？你是从其他人的剧本中复制过的吗？

函数gimp-file-load返回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，以便它可以存储在“img”变量中。而不是（img（myimage（gimp-file-load RUN-INTERACTIVE filename filename）））应该说（img（car（gimp-file-load RUN-INTERACTIVE filename filename）））

另外，我认为你可能想要使用RUN-NONINTERACTIVE。

同样，我认为你需要改变彼此的实例（我的形象......）成为（车......）代替。

script-fu脚本无法在gimp 2.0下加载图像
