void Vect_line_buffer | ( | const struct line_pnts * | InPoints, |
double | distance, | ||
double | tolerance, | ||
struct line_pnts * | OutPoints | ||
) |
Create buffer around the line line.
This function is replaced by Vect_line_buffer().
Buffer is closed counter clockwise polygon. Warning: output line may contain loops!
InPoints | input line | |
distance | create buffer in distance | |
tolerance | maximum distance between theoretical arc and polygon segments | |
[out] | OutPoints | output line |
void Vect_line_parallel | ( | struct line_pnts * | InPoints, |
double | distance, | ||
double | tolerance, | ||
int | rm_end, | ||
struct line_pnts * | OutPoints | ||
) |
Create parallel line.
This function is replaced by Vect_line_parallel2().
InPoints | input line | |
distance | create parallel line in distance | |
tolerance | maximum distance between theoretical arc and polygon segments | |
rm_end | remove end points falling into distance | |
[out] | OutPoints | output line |
