regionDraw

Name

regionDraw - draw one or more y-line regions in a band

Syntax

 #include <xite/region.h>

 int regionDraw( IBAND band, region* reg,
    int loop, int pv );

Description

The region specified by "reg" is drawn in the "band" with pixel value "pv". The region is clipped against the border of the image; eventual parts of the region outside the band are not drawn. If "loop" is true, the next pointer in reg is followed until NIL, and all regions are drawn. If "pv" = -1, the object number of each region is used as pixel value. If "pv" = -2, the region number of each region is used as pixel value.

Return value

 0 => ok
 1 => bad band pixel type
 2 => bad region specification
 3 => pixel value outside -2..255
