Name
overlap - calculate overlapping area of two bands
Syntax
#include <xite/copy.h>
int overlap( IBAND ib1, IBAND ib2, IBAND* ob1,
IBAND* ob2 );
Description
Input bands ib1 and ib2 are placed in a common
coordinate system according to their (xstart, ystart)
attributes. The overlapping area is calculated, and
two subbands ob1 and ob2 are created and returned,
pointing out the overlapping area in each band.
ob1 will thus be a subband of ib1, and ob2 will
be a subband of ib2.
Restrictions
Only accepts unsigned byte pixeltype.
Return value
0 => ok,
1 => bad pixel type input band 1
2 => bad pixel type input band 2
3 => no overlap
