GLPaint brush effect with blur and bevel

I am working on a graphical application based on GLPaint code. Does anyone know how to achieve this effect? I tried with different widths and heights for the brush, but still remains the same.

Do I need to consider glBlendFunc ()? or Whether a complete change in the width and height of the brush is achievable.

Thanks in advance. enter image description here

The easiest way to achieve this effect is to reduce alpha from 1.0 to 0.7.
