Constructor Details

DirectResamplingMapFactory

public DirectResamplingMapFactory(EarthTransform sourceTrans,
 EarthTransform destTrans)

Creates a new resampling factory from the source and destination transforms.

Parameters:

sourceTrans - the source earth transform.

destTrans - the destination earth transform.

Method Details

create

public ResamplingMap create(int[] start,
 int[] length)

Description copied from interface: ResamplingMapFactory

Creates a new resampling map that covers a specified set of destination coordinates.

Specified by:

create in interface ResamplingMapFactory

Parameters:

start - the starting rectangle coordinates in the destination space as [row, col].

length - the size of the rectangle in destination space as [rows, cols].

Returns:

a resampling object that covers the specified destination rectangle or null if the destination rectangle has no corresponding coordinates in the source space.
