print imagemagick将输出转换为浏览器

我有以下代码:

import subprocess
convertargs = ['convert', 'image1.tif', 'img2.tif', 'pdf:-']
print "Content-type: application/pdf\r\n\r\n"

pdf = subprocess.Popen(convertargs, stdout=subprocess.PIPE)
pdf, error = pdf.communicate()

print pdf

它应该采用convertargs,使用imagemagick转换将图像转换为PDF格式。

我知道这有效,因为当我在shell上运行以下内容时:

./pdf.py > test.pdf

它为我创建了一个带有正确图像的整洁小PDF。但是,当我访问www.myhost.com/pdf.py时,它不起作用。我无法弄清楚原因。 这是我的apache错误日志所说的内容:

Traceback (most recent call last):: /Library/WebServer/Documents/pdf.py
   File "/Library/WebServer/Documents/pdf.py", line 59, in <module>: /Library/WebServer/Documents/pdf.py
     pdf = subprocess.Popen(convertargs, stdout=subprocess.PIPE): /Library/WebServer/Documents/pdf.py
   File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/subprocess.py", line 710, in __init__: /Library/WebServer/Documents/pdf.py

subprocess.Popen无法找到convert,可能是因为网络服务器使用了不同的$ PATH。尝试将其提供给convert的完整路径,而不仅仅是convert
