Class Transferer.FloatToDirect

java.lang.Object

org.apache.sis.image.Transferer

org.apache.sis.image.Transferer.FloatToDirect

Enclosing class:

Transferer

private static final class Transferer.FloatToDirect
extends Transferer

Read float values from the source and write float values directly in the target raster, without intermediate buffer. This strategy is possible only when the target raster uses the float type for storing sample values. This operation is executed in one step, without subdivisions in strips.

Method Details

computeStrip

void computeStrip(org.opengis.referencing.operation.MathTransform1D converter)
           throws org.opengis.referencing.operation.TransformException

Copies source values directly in the target, then applies the conversion in-place.
