regionEndInsert

Name

regionEndInsert - clean up region at end of yline insertion

Syntax

 #include <xite/region.h>

 BiffStatus regionEndInsert( region* reg );

Description

the "ylines" array in reg is searched for first and last occurrence of a pointer, and the array is then reallocated to fit exactly the required size. Finally reg->ymin and reg->ymax is updated.

This routine should always be called after inserting or deleting ylines into an region, unless you are sure that the object really spans ymin..ymax.
