将PDF转换为TIFF，600dpi和jpg 96 dpi

Question

我想使用ImageMagick将pdf转换为600 dpi的tiff和来自Python脚本的96 dpi的jpg。

我使用（imagemagick）命令行完成了这项任务，但我想在python中使用Imagemagick将pdf转换为tiff和jpg，

你可以帮助我......

Answer 1

使用PythonMagick：

import PythonMagick

img = PythonMagick.Image()
img.density('600')  # you have to set this here if the initial dpi are > 72

img.read('test.pdf') # the pdf is rendered at 600 dpi
img.write('test.tif')

img.density('96')  # this has to be lower than the first dpi value (it was 600)
# img.resize('100x100')  # size in px, just in case you need it
img.write('test.jpg')  

Answer 2

您可以使用 subprocess module 执行imagemagick命令

import subprocess
params = ['convert', "Options", 'pdf_file', 'thumb.jpg']
subprocess.check_call(params)
