Thank you for the replies.
Binary, could you tell me more (or connect me to the right people) to discuss concrete details of your last suggestions (the CI infrastructure).
Thanks,
Robert

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.

SFML specific time based movement discussion: http://stackoverflow.com/questions/18306101/movement-without-framerate-limit-c-sfml
I would urge you to do a basic google search on these topics before posting here. This community is very helpful, but failing to do even a cursory look for answers on your own won't get you very far. Good luck!

I urge you to make a minimum viable example so that people can see what your doing.

Graphics / Re: Alpha artifacts
« on: November 11, 2014, 03:13:45 pm »You could try to enable the window's anti-aliasing to affect the whole rendered screen, not just a transformed texture.
Are you talking about openGL multisampling? If so, I am currently using multisampling with a value of 4 when the context is created.

Laurent,
Thanks for the reply. I am using
in my draw call for debugging and it gives even greater issues
This was rendered with mipmaps set to GL_LINEAR (which I believe SFML does with texture smoothing). I 'm thinking this is not a pre-multiplied alpha issue, but I'm really not sure what to check next.
Here is the text graphic that is being rendered on top of the other images if your interested:

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

C / Re: CSFML cmake broken?
« on: September 25, 2014, 05:59:02 pm »
My issue was solved (Thanks to Tank) by running the install target with SFML, clearing the CMake cache for the CSFML project, manually setting the SFML_ROOT var to the newly installed directory, and running configure again.

I am compiling the latest source from github for all 3 projects (SFML, CSFML, and the .NET bindings). CSFML never makes it past the 'configure' step with CMake.

Has this issue been resolved yet? I've been trying to configure CSFML with CMake on Windows for a the past half hour and it never seems to find the SFML libs it is interested in. I have to manually tell it where to find the SFML dependencies (glew, freetype, etc...) and even after that it blows up with:
CMake Error at C:/Program Files (x86)/CMake 2.8/share/cmake-2.8/Modules/FindSFML.cmake:344 (message):
Could NOT find SFML (missing: SFML_SYSTEM_LIBRARY SFML_WINDOW_LIBRARY
SFML_NETWORK_LIBRARY SFML_GRAPHICS_LIBRARY SFML_AUDIO_LIBRARY)

Most of these getter-to-property conversions sound reasonable. I am currently using the NetEXT timer classes for everything I need, so no protest against them. The biggest thing in the list for me was the inclusion of OpenTK. Great list Zachariah!

Thanks! I pulled the changes and they worked perfectly. I used your new documentation to build it as well!

Update: If I start play back and then give the thread a brief sleep it does not flash black. These feels like a hack tho. What are your thoughts?
