Interface JNCSProgressiveUpdate

All Known Implementing Classes:

JNCSFile

public interface JNCSProgressiveUpdate

JNCSProgressiveUpdate is an interface that clients must implement to listen to progresive imagery form the ECW classes.

Since:

ECW Java SDK 2.3

Method Summary

void	refreshUpdate(int nWidth, int nHeight, double dWorldTLX, double dWorldTLY, double dWorldBRX, double dWorldBRY) This method gets called when imagery arrives from the network and the set view was in world coordinates.
void	refreshUpdate(int nWidth, int nHeight, int dDatasetTLX, int dDatasetTLY, int dDatasetBRX, int dDatasetBRY) This method gets called when imagery arrives from the network, and the set view was in dataset cells.

Method Detail

refreshUpdate

public void refreshUpdate(int nWidth,
                          int nHeight,
                          double dWorldTLX,
                          double dWorldTLY,
                          double dWorldBRX,
                          double dWorldBRY)

This method gets called when imagery arrives from the network and the set view was in world coordinates. When using progressive imagery, clients must implement this class.

Parameters:

nWidth - The width of the setView which generated this callback

nHeight - The height of the setView which generated this callback

dWorldTLX - The top left X coord that generated this callback

dWorldTLY - The top left Y coord that generated this callback

dWorldBRX - The bottom right X coord that generated this callback

dWorldBRY - The bottom right Y coord that generated this callback

                          int dDatasetTLY,
                          int dDatasetBRX,
                          int dDatasetBRY)

This method gets called when imagery arrives from the network, and the set view was in dataset cells. When using progressive imagery, clients must implement this class.

Parameters:

nWidth - The width of the setView which generated this callback

nHeight - The height of the setView which generated this callback

dDatasetTLX - The top left X dataset cell that generated this callback

dDatasetTLY - The top left Y dataset cell that generated this callback

dDatasetBRX - The bottom right X dataset cell that generated this callback

dDatasetBRY - The bottom right Y dataset cell that generated this callback
