示例1: computePoly
void HiJitCube::computePoly() {
// Compute sample and line coordinates in the focal plane
int samp0,sampN;
if (originst) {
samp0=jdata.fpSamp0 + jdata.sampOffset;
sampN=samp0 + npSamps[jdata.cpmmNumber] - 1;
} else {
samp0=jdata.fpSamp0 + jdata.sampOffset;
sampN=samp0 + Samples() - 1;
}
int line0(jdata.fpLine0 + jdata.lineOffset), lineN(line0 + Lines() - 1);
// Allocate a new coordinate sequence and define it
geos::geom::CoordinateSequence *pts = new geos::geom::CoordinateArraySequence();
pts->add(geos::geom::Coordinate(samp0, lineN));
pts->add(geos::geom::Coordinate(sampN, lineN));
pts->add(geos::geom::Coordinate(sampN, line0));
pts->add(geos::geom::Coordinate(samp0, line0));
pts->add(geos::geom::Coordinate(samp0, lineN));
// Make this reentrant and delete previous one if it exists and get the
// new one
delete fpGeom;
fpGeom = geosFactory.createPolygon(geosFactory.createLinearRing(pts), 0);
return;
