示例1: computeSizeBasedSnapTolerance
/*public static*/
double
GeometrySnapper::computeOverlaySnapTolerance(const geom::Geometry& g)
{
double snapTolerance = computeSizeBasedSnapTolerance(g);
/**
* Overlay is carried out in the precision model
* of the two inputs.
* If this precision model is of type FIXED, then the snap tolerance
* must reflect the precision grid size.
* Specifically, the snap tolerance should be at least
* the distance from a corner of a precision grid cell
* to the centre point of the cell.
*/
assert(g.getPrecisionModel());
const PrecisionModel& pm = *(g.getPrecisionModel());
if (pm.getType() == PrecisionModel::FIXED)
{
double fixedSnapTol = (1 / pm.getScale()) * 2 / 1.415;
if ( fixedSnapTol > snapTolerance )
snapTolerance = fixedSnapTol;
}
return snapTolerance;
