Thank you Rusi and Christian!
So it sounds like I should read the pdf data in as binary:
--------------------
import os
pdfPath = '~/Desktop/test.pdf'
colorlistData = ''
with open(os.path.expanduser(pdfPath), 'rb') as f:
for i in f:
if 'XYZ:colorList' in i:
colorlistData = i.split('XYZ:colorList')[1]
break
print(colorlistData)
--------------------
This gives me the error:
TypeError: Type str doesn't support the buffer API
I admit I know nothing about binary, except it's ones and zeroes. Is there a way to read it in as binary, convert it to ascii/unicode, and then somehow split it by newline characters so that I can pull the appropriate metadata lines out? For example, XYZ:colorList="DarkBlue,Yellow"
Thanks!
Jay
