General discussions / Giving back

« on: March 26, 2015, 03:54:37 pm »

Greetings,

  I work for a company that uses SFML and several of it's libraries every day.  Yesterday the topic of how to give back came up in a meeting.  I would like to hear from the core members on how they think I might be able to support the project.  Giving code is probably not an option, our code is very specific to our use case and is probably no good to anyone else.  We would, however, be interested in giving back in some other way.  I would like to know what the project could use and how my company can help.

Thanks.

Graphics / Alpha artifacts

« on: November 10, 2014, 03:52:20 pm »

Hey guys,

  I was experimenting with implementing a runtime in SFML for GrapeFrukt exported animations (https://github.com/grapefrukt/grapefrukt-export).  But I have run into a bit of an issue I feel ill equipped to tackle.  In my first run, I noticed that all the animations were extremely pixelated when transformed (scaled, rotated, etc..), so I turned on texture smoothing.

This fixed a lot of my aliasing issues, but introduced a bunch of alpha artifacts around the text that has a drop shadow.  
It looks like a pre-multiplied alpha issue, but I'm not sure how to fix it in SFML (I'm using the .NET bindings).  I did a search for "pre-multiplied" and came up with very little.  I'm fairly certain this could be address with the new BlendMode stuff in the SFML repo, but documentation on how to use it is a bit scarce at the moment.

Thanks,
Rob
