Hi,
is there a way, to make sharper corners for alphamasking?
The black pixels dosent looks good :-(

Improved Alpha-Tested Magnification

thanks, for this.
Is there an easy way, to implement this with OpenGL?

Try turning on both blending and testing, then adjusting the test value until you can see the smooth blended edge - assuming your alpha channel is smooth!

This hack can and will result in errors with overlapping surfaces if you don't draw back to front, but for sharp-edged alphas as in your screenshot these errors should be tolerable without sorting.

Thanks,
it looks better with blending (not perfect, but ok ;-) )

Also for that texture you could rotate it so that the edges are parallel with the image edges.
