fli*_*ixe 1 python cmd gimp gimpfu
我正在尝试使用gimp 2.8.22的功能将pdf转换为jpeg,我想使用Windows cmd中的gimpfu库使用python脚本进行此操作(我已经安装了python 3.6.1)。
现在,我不尝试使用示例脚本来做到这一点:
#!/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

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,我总是会收到相同的错误消息:
(gimp-2.8:1020):LibGimpBase-警告**:gimp-2.8:gimp_wire_read():错误
编辑:好的,谢谢。我省略了接口声明,还尝试了最简单的示例来找出问题所在:
#!/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本身运行脚本时,该脚本实际上有效,但是当我尝试从自己的cmd运行脚本时,Gimp打开,并显示另一个cmd: Error: ( : 1) eval: unbound variable: hello_world
有人知道我在这里想念的吗?
要运行python脚本,您不需要将其注册为插件。恕我直言,您甚至应该避免这种情况,这不必要地污染了Gimp的菜单和过程名称空间。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

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

慢动作参数:
-idf:无需用户界面即可工作,并且既不加载数据也不加载字体(您可能需要保留字体才能加载pdf)--batch-interpreter python-fu-eval:以下-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;:扩展导入路径以包括当前目录import batch;:使用我们的脚本导入文件,该脚本现在位于路径的目录中。batch.run('./images'):调用我们导入run()的batch模块的函数,为其指定包含要处理图像的目录的名称。-b "pdb.gimp_quit(1)":另一段python:完成后退出。 请注意,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,在Windows中事情很复杂,因为始终没有标准输出流。有帮助的事情:
-i暂时删除该参数,以便您获得UI并可能有机会看到消息。--verbose使Gimp启动辅助控制台窗口。(*)在Linux / OSX Shell中,情况相反:在外壳中使用单引号,在Python中使用双引号。
