Source: visp

Severity: Serious

Hi visp Maintainer(s),
your package has been found to contain a copy of a non DFSG
file, that makes your package non DFSG.

This image (called lenna.jpg, or lena.jpg with some variants)
is an image of Lena Söderberg, photographed by Dwight Hooker,
cropped from the centerfold of the November 1972 issue of Playboy magazine.

This file is to be considered distributable but non free
(at the end of this bug report you will find a link to the lintian tag,
with a more complete description of the issue and references)

Below a list of the affected files:
- doc/image/img-lena-blured-default.png
- doc/image/img-lena-blured-var2.png
- doc/image/img-lena-canny.png
- doc/image/img-lena-dIxy.png
- doc/image/img-lena-gray.png
- doc/image/img-lena-pyr.png
- doc/image/img-lena-sobel.png
- doc/image/img-lena-win.jpg
- doc/image/img-lena.png
- tutorial/image/lena.bmp
- tutorial/image/lena.jpeg
- tutorial/image/lena.pgm
- tutorial/image/lena.png
- tutorial/image/lena.ppm

note, I did stop checking for the all files as soon as I found one
good match, so they might be not all bad references, please update
this bug if not correct.
