Licence for PngSuite?

[Pavel Tisnovsky]

Hi all,

I'd like to create new regression test for checking image reader/writer
behaviour and for this I need some useful PNG images.

Below are my conversation with the author of PngSuite
(http://www.schaik.com/pngsuite/pngsuite.html) with his permission to
use his images in OpenJDK.

Do you think that this permission allow as to add these images to
OpenJDK OR at least to IcedTea?

Cheers
Pavel

Hi Pavel,

Five or six years ago I had a very similar discussion with "your
friends" ;-) from Novell/SuSE. They needed to be sure that legally they
were OK with including PngSuite somewhere in their distro.

The 'legal' status of PngSuite, if you can even call that, is that
anybody may use it any way they like. You may include it in any piece of
software, no matter if that's GPL, freeware or commercial.

When I created PngSuite at the time, I created every single image from
scratch. There was nothing used, borrowed, etc. from existing images. I
did it that way because nothing out there was usable, but the advantage
is that the end result has no depending copyright issues.

Let me know if you need anything more official than this.

See you,
Willem


PS. I've been and still am a "RedHat guy" since 1985, when I switched
from Slackware :). PngSuite was generated on RedHat 3.0.3 and my current
desktop is CentOS. Laptops are running Fedora and the PVR is MythDora.
OpenJDK is also close to my heart, having been with Sun Microsystems the
last 10 years. Mow with Cisco, selling Redhat on UCS.
