Python_fu 插件不会在 gimp 中加载

Question

我正在尝试使用 python_fu 编写一个 gimp 插件。我希望它采用许多相同大小的图层并将它们放在垂直线上。这将用于打开每个页面占据一层的 pdf 文件，并且该插件会将它们排成一行。但是，当我运行该插件时，菜单中没有显示任何内容。当我注释掉上面带有星号的行时，插件会加载到菜单中。

%UserProfile%\.gimp-2.8\plug-ins\Array.py

from gimpfu import *

def plugin_main(timg, tdrawable, widthNum, heightNum):

    layers = gimp-image-get-layers(timg) #<< Gets a list of all the layers

    #Sets the WIDTH and HEIGHT to the size of the first image
    WIDTH = layers[0].width
    HEIGHT = layers[0].height

    #Loops through all layers and moves them
    for i in range(layers.length):
        location = float((i+1)*HEIGHT)
        #*****
        transformedimage = gimp-item-transform-2d(layers[i], 0.0, 0.0, 1.0, 1.0, 0.0, location) #<< When I comment this line out the plugin loads

    gimp-image-resize-to-layers() #<< Resizes the image to fit the moved layers

register(
        "python_fu_array",
        "Sets out your layers as tiles",
        "Sets out your layers as tiles",
        "author",
        "author",
        "2016",
        "<Image>/Image/Array",
        "RGB*, GRAY*",
        [],
        [],
        plugin_main)

main()

看看一些现有的基于Python的插件，例如https://git.gnome.org/browse/gimp/tree/plug-ins/pygimp/plug-ins/py-slice.py

注意一些过程是如何被调用的，例如第 168 行: https://git.gnome.org/browse/gimp/tree/plug-ins/pygimp/plug-ins/py-slice.py#n168

temp_image = pdb.gimp_image_new (...)

您的代码有两个不同之处:

1. pdb 前缀
2. 使用下划线代替连字符/减号

更改您的插件以执行此操作，您将更进一步。
