FIrst off, thank you so much for this lovely app!

I am trying to conver a jpeg 2k file to pdf:

You can find the file here:

https://github.com/CodecCentral/openjpeg-data/tree/master/input/conformance

File name is:

zoo1.jp2

I get an error : broken data stream when reading image file

Thanks!
Aaron

PS I am using the latest github source

I actually get a different error:

Traceback (most recent call last):
  File "src/img2pdf.py", line 340, in <module>
    main()
  File "src/img2pdf.py", line 337, in main
    args.subject, args.keywords, args.colorspace, args.verbose))
  File "src/img2pdf.py", line 220, in convert
    width, height, ics = parsejp2(rawdata)
  File "/home/josch/img2pdf/src/jp2.py", line 75, in parsejp2
    width, height, colorspace = parse_jp2h(boxContents)
  File "/home/josch/img2pdf/src/jp2.py", line 64, in parse_jp2h
    colorspace = parse_colr(boxContents)
  File "/home/josch/img2pdf/src/jp2.py", line 52, in parse_colr
    raise Exception("only sRGB and greyscale color space is supported, got %d"%enumCS)
Exception: only sRGB and greyscale color space is supported, got 18

Color 18 is sYCC. I would not know how to handle images in that color space.

Thanks for checking. It is strange that we get different errors. I am using python 2.7 on windows, if that makes a difference.

I'm using python 2.7 and python-pil 2.3.0 on Debian testing. I'm more interested in what part exactly throws your error message " broken data stream when reading image file"

By boxerab on 2014-04-05 21:13:24 UTC

OK, how can I test this for you?

By josch on 2014-04-05 21:16:55 UTC

Well, usually when you run a Python program and it exits because of an error, it gives you a traceback looking like the one I pasted above. Apparently no source package in all of Debian contains the string "broken data stream when reading image file" so I'm at a loss where it could come from.

ahhh, it is a PIL error:

yeah, I found that this is an error with the version of PIL that I have. So, don't worry about it.
I shouldn't be using windows anyways :)
