Title: Use of Vampyre Imaging in commercial software and Animated pngs in Firefox
Post by: mkoijn on 4 June 2011, 12:02:28
Hi, Vampyre Imaging is a great library, thanks for making it available. I'm slightly confused by the lgpl license,
can I use the library (I haven't modified it) in a commercial application? I think I can if I understand the license, but do I have to include the source code for vampyr? or do I have to release my source code too? or
do I have to just give credit to Vampyre Imaging in the documentation to the software?

Also, the animated png's I produce with Vampyre look great and work in Opera, but not Firfox 3.6.12, there the colors are all garbled.

best regards

Albert

Hi, could you attach some of the APNGs that cause problems to this post?

Imaging is dual licensed LGLP and MPL. For commercial project it's simpler to choose MPL,
I added LGPL just to make Imaging compatible with GPL projects.

There's a nice explanation of MPL usage on Asphyre page: http://dev.ixchels.net/forum/faq.php?faq=asphyre_license (http://dev.ixchels.net/forum/faq.php?faq=asphyre_license)

It looks ok in Firefox 4, maybe some bug in 3.6?
Is the first frame ok and the others garbled or everything is garbled?

Yes it could be a bug in 3.6, but I imported my png into another program which works with animated gifs(apngopt) and resaved from there and that works in firefox 3.6.
I can't tell if the first frame shows okay or not.

Thanks

Albert

Could you upload that fixed APNG? It would be helpful if I could see the internal differences
between the original from Imaging and the one that works in FF 3.6. Thanks

Here's the png after saving in apngopt.

Thanks a lot

I have fixed one bug in APNG loading code.
Do you still have problems with saving APNGs?
