Dear sir, 

I am using the boost geometry for my project recently. 
In my project, I need a negative buffer. 
I notice that I need to use the trunk version buffer for the general
polygons. 

However, it seems that the buffer function do not support negative buffer. 
When I set the distance to a negative value, I get nothing. 

Is there another way to satisfy the negative buffer? 

Best regards, 
Guo Long
