Problem with drawing sprites
« on: February 26, 2011, 07:40:57 pm »
Hi. First thanks for your great library. I'm a new game developer in c++ and SFML. I'm professional in game making but with use of Visual Engines like Unity or UDK.

I wanna to ask why my sprite get a yellow border when I rotate it. I using a transparented PNG image and think I should use a bitmap image using keycolor to transparent the background but maybe there will be a better solution to do with the PNG one.

picture will tell all the issue:

Try SetSmooth(false) on the image.

My guess would be that your image has those yellow lines to make it more antialiased, but they are unoticed when the line is straight vertical/horizontal. When you start rotating, those lines become pixelated, and more noticeable.

Hope that's it as i can't see any other way that would make a border like that only when rotating.

EDIT: ofc, or SetSmooth() as previously said :)
