ImageMagick未授权将PDF转换为图像我有一个程序,在这个程序中,我需要使用ImageMagick将PDF转换成图像。我用subprocess一揽子: cmd = 'magick convert -density 300 '+pdfFile+'['+str(rangeTuple[0])+'-'+str(rangeTuple[1])+'] -depth 8 '+'temp.tiff' #WINDOWS
if(os.path.isfile('temp.tiff')):
os.remove('temp.tiff')
subprocess.call(cmd,shell=True)
im = Image.open('temp.tiff')我得到的错误是:convert-im6.q16: not authorized `temp2.pdf' @ error/constitute.c/ReadImage/412.
convert-im6.q16: no images defined `temp.tiff' @ error/convert.c/ConvertImageCommand/3258.Traceback (most recent call last):

fp = builtins.open(filename, "rb")FileNotFoundError: [Errno 2] No such file or directory: 'temp.tiff'其中最重要的是:convert-im6.q16: not authorized `temp2.pdf' @ error/constitute.c/ReadImage/412.我认为这是因为ImageMagick没有被授权访问PDF。现在应该做些什么呢?我在Linux服务器上。任何帮助都是非常感谢的。
