如何使用windows命令行中的gimpfu运行python脚本？

我正在尝试使用gimp 2.8.22的函数将pdf转换为jpeg,我想使用我的windows cmd中的gimpfu库(我安装了python 3.6.1)使用python脚本.

现在,我不想尝试使用示例脚本：

#!/usr/bin/env python

# Hello World in GIMP Python

from gimpfu import *

def hello_world(initstr, font, size, color) :
    # First do a quick sanity check on the font
    if font == 'Comic Sans MS' :
        initstr = "Comic Sans? Are you sure?"

    # Make a new image. Size 10x10 for now -- we'll resize later.
    img = gimp.Image(1, 1, RGB)

    # Save the current foreground color:
    pdb.gimp_context_push()

    # Set the text color
    gimp.set_foreground(color)

    # Create a new text layer (-1 for the layer means create a new layer)
    layer = pdb.gimp_text_fontname(img, None, 0, 0, initstr, 10,
                                   True, size, PIXELS, font)

    # Resize the image to the size of the layer
    img.resize(layer.width, layer.height, 0, 0)

    # Background layer.
    # Can't add this first because we don't know the size of the text layer.
    background = gimp.Layer(img, "Background", layer.width, layer.height,
                            RGB_IMAGE, 100, NORMAL_MODE)
    background.fill(BACKGROUND_FILL)
    img.add_layer(background, 1)

    # Create a new image window
    gimp.Display(img)
    # Show the new image window
    gimp.displays_flush()

    # Restore the old foreground color:
    pdb.gimp_context_pop()

register(
    "python_fu_hello_world",
    "Hello world image",
    "Create a new image with your text string",
    "Akkana Peck",
    "Akkana Peck",
    "2010",
    "Hello world (Py)...",
    "",      # Create a new image, don't work on an existing one
    [
        (PF_STRING, "string", "Text string", 'Hello, world!'),
        (PF_FONT, "font", "Font face", "Sans"),
        (PF_SPINNER, "size", "Font size", 50, (1, 3000, 1)),
        (PF_COLOR, "color", "Text color", (1.0, 0.0, 0.0))
    ],
    [],
    hello_world, menu="<Image>/File/Create")

main()

我尝试从我的cmd运行脚本,如下所示：

gimp-2.8 --no-interface --batch '(python_fu_hello_world RUN-NONINTERACTIVE "Hello" Arial 50 red)' -b '(gimp-quit 1)'

但是,无论我做什么,我总是会出现同样的错误信息：

(gimp-2.8:1020): LibGimpBase-WARNING **: gimp-2.8: gimp_wire_read():
error

编辑：好的,谢谢.我省略了接口语句,我也尝试了最简单的例子来弄清楚什么是错误的：

#!/usr/bin/env python

# Hello World in GIMP Python

from gimpfu import *

def hello_world():
 gimp.message("Hello, GIMP world!\n")

register(
 "hello_world",
 'A simple Python-Fu "Hello, World" plug-in',
 'When run this plug-in prints "Hello, GIMP world!" in a dialog box.',
 "Tony Podlaski",
 "Tony Podlaski 2017. MIT License",
 "2017",
 "Hello World",
 "",
 [],
 [],
 hello_world,
 menu="<Image>/Filters/HelloWorld",
)

main()

当我从Gimp本身运行它时,该脚本实际上有效,但是当我尝试从我的cmd运行它时,Gimp打开另一个cmd说：错误：(：1)eval：未绑定变量：hello_world

有人知道我在这里缺少什么吗？

解决方法:

要运行python脚本,您不需要将其注册为插件.恕我直言,你甚至应该避免这种情况,这会不必要地污染Gimp的菜单和程序名称空间.这是一个例子：

批处理脚本(保存为batch.py​​)：

#!/usr/bin/python
# -*- coding: iso-8859-15 -*-

import os,glob,sys,time
from gimpfu import *


def process(infile):
        print "Processing file %s " % infile
        image = pdb.file_jpeg_load(infile,infile)
        drawable = pdb.gimp_image_get_active_layer(image)

        print "File %s loaded OK" % infile
        pdb.plug_in_photocopy(image, drawable,8.,0.8,0.2,0.2)
        pdb.plug_in_cartoon(image, drawable, 7.,0.2)
        outfile=os.path.join('processed',os.path.basename(infile))
        outfile=os.path.join(os.path.dirname(infile),outfile)
        print "Saving to %s" % outfile
        pdb.file_jpeg_save(image, drawable, outfile, outfile, "0.5",0,1,0,"",0,1,0,0)
        print "Saved to %s" % outfile
        pdb.gimp_image_delete(image)


def run(directory):
        start=time.time()
        print "Running on directory \"%s\"" % directory
#   os.mkdir(os.path.join(directory,'processed'))
        for infile in glob.glob(os.path.join(directory, '*.jpg')):
                process(infile)
        end=time.time()
        print "Finished, total processing time: %.2f seconds" % (end-start)


if __name__ == "__main__":
        print "Running as __main__ with args: %s" % sys.argv

打电话给它：

gimp -idf --batch-interpreter python-fu-eval -b "import sys;sys.path=['.']+sys.path;import batch;batch.run('./images')" -b "pdb.gimp_quit(1)"

慢动作中的参数：

> -idf：没有用户界面工作,既不加载数据也不加载字体(你可能需要保留字体来加载pdfs)
> –batch-interpreter python-fu-eval：无论后面是什么-b是Python,而不是script-fu
>“import sys; sys.path = [‘.’] sys.path; import batch; batch.run(‘./ images’)”：我们要求Gimp执行的代码,即：

> import sys; sys.path = [‘.’] sys.path;：扩展导入路径以包含当前目录
> import batch;：使用我们的脚本导入文件,该脚本现在位于路径的一部分目录中.
> batch.run(‘./ images’)：调用我们导入的批处理模块的run()函数,为其提供包含要处理的图像的目录的名称.

> -b“pdb.gimp_quit(1)”：另一段python：完成后退出.

注意命令行如何巧妙地使用双引号和单引号将所有参数传递给Gimp,然后传递给Python(*).是的,您可以在Windows中使用正斜杠作为文件分隔符.

要进行调试,Windows中的问题有点复杂,因为并不总是有stdout流.可以帮助的事情：

>暂时删除-i参数,以便获得UI并可能有机会查看消息.
>添加–verbose,使Gimp启动辅助控制台窗口.
>还有其他技巧可以看到列出的消息here.
>您也可以正常启动Gimp并从Python-fu控制台运行您的脚本(过滤器> Python-fu>控制台).您必须扩展路径并“手动”导入文件.

(*)在Linux / OSX shell中,人们会做相反的事情：shell的单引号,Python的双引号.
