Craig Russell commented on SANSELAN-9:
--------------------------------------
Would it be possible to reproduce this issue with an image that can be licensed
to Apache? Not a huge problem if not, but it would be nice to have a regression
test case that can be checked into svn...
> Loading Black and White PNGs produces darker images.

> Key: SANSELAN-9
> URL: https://issues.apache.org/jira/browse/SANSELAN-9
> Project: Sanselan
> Issue Type: Bug
> Affects Versions: 0.94-incubator
> Environment: Mac OSX 10.5+, Java 1.5+, Sanselan 0.94
> Reporter: Kevin Theisen
>
> When saving and loading pngs with Sanselan, black and white images get
> darker with each save and load. All images are held in
> memory as BufferedImages (ARGB). Have you ever seen this weird behavior
> before or how I may fix it?
> The affected images may be all PNGs, but I see this effect happening in
> images that contain mostly black and white pixels. The image I use to
> demonstrate this problem is from a wikipedia page of Linus Pauling:
> http://en.wikipedia.org/wiki/Linus_Pauling
> The image basically goes to black after saving and loading 3/4 times.
