[GRASS-dev] Vect_line_buffer tolerance setting

[Maris Nartiss]

Hello all,

I was going to use Vect_line_buffer function but was unable to
understand it's tolerance parameter. Could somebody extend a bit
documentation to make it more clean what does it mean.

For my module I need to create buffer around line without any "round
caps" at line end -> buffer must look like square and not extend
beyond input line end. Ideas how to tweak tolerance setting to get
such functionality out of Vect_line_buffer?

Thanks!
Maris.
