Interface JiffleIndirectRuntime

All Superinterfaces:

JiffleRuntime

All Known Implementing Classes:

AbstractIndirectRuntime

public interface JiffleIndirectRuntime
extends JiffleRuntime

Defines methods implemented by runtime classes adopting the indirect evaluation model. In this model, there is only a single destination image and the evaluate(int, int) method passes values back to the caller rather than writing them to the destination image directly.

Since:

1.1

Method Summary

double	evaluate(int x, int y) Evaluates the script for the given image location.
double	readFromImage(String srcImageName, int x, int y, int band) Gets a value from a source image as a double.
void	setDestinationImage(String imageName) Specifies the variable in the Jiffle script which refers to the destination image.
void	setSourceImage(String imageName, RenderedImage image) Associates a variable name in the Jiffle script with a source image.
