if 'W' in obj and 'H' in obj: TypeError: argument of type 'PSLiteral' is not iterable

I am running this command on a 25 Mo input PDF file :

pdf2txt.py -S -t xml -o pdfMinerOutput.xml input.pdf

It crashes with this stack trace :

Traceback (most recent call last):

I have had a quick look at this.

I didn't look at what the function is really doing; but all that is happening is those values are null.

I edited /usr/lib/python2.7/site-packages/pdfminer/pdfinterp.py

line 789 for me.

if 'W' in obj and 'H' in obj:

I replaced this with

if hasattr(obj,'W') and hasattr(obj,'H'):

which is a better way of checking these values.

Works perfectly.

Im going to test this method for a week with my system where we are using this library heavily. Then im going to create a PR for this.

Do you know if the owner is still adding PR?
