Selection tool adding transparency [Solved] - RealWorld forums

Hi

When I select my drawing, it sometimes add a bit or transparency on the borders!! How can I force RWPaint to not modify my image when I am just selecting it?

I works with small images (16x16 pixels) and I notice it quite often.
It would be almost impossible to spot the changes with a big image, but on pixel-arts/smileys, I work always with a big zoom, so I see when pixels are not 100% black anymore.

While making tests to explain more where this problem come from, I FOUND!!!
This Problem come from the Bézier transformation!!!
So, problem solved.
Thanks for your listening.
