GLPaint Brush Effect with blur and bevel

问题

I am working on a drawing application based on GLPaint code. Do somebody know how to get an effect like this ? I have tried with different values for the width and the Height for the brush, but still it remains same .

Do i need to consider glBlendFunc() ? or Is it achievable thorough changing the width and the heigh of the brush.

Thanks in advance.

回答1:

The easiest way to achieve that type of effect is to reducing the alpha from 1.0 to 0.7.

回答2:

In PaintingView Change Brush Height and Width as shown in following image...And One more thing is that change brush image according to your requirements for more color custom effect..

Hope, this will help you..
