public interface IlvTileElevationProvider

This interface describes a two dimensional array that can return elevation values for points within its limits

Since:

JViews 7.5

Method Summary

Modifier and Type	Method and Description
int	getHeightAt(int level, int line, int column) Returns an elevation value for the specified line and column values.
int	getTileHeight() Returns the number of lines in this IlvTileElevationProvider;
int	getTileWidth() Returns the number of columns in this IlvTileElevationProvider.

Method Detail

getHeightAt

int getHeightAt(int level,
                int line,
                int column)

Returns an elevation value for the specified line and column values. The parameter level is a convenient way to query elevation values for downsampled resolutions. Note that line and columns parameters should be within [0, getTileHeight() / 2exp(level)] and [0, getTileWidth() / 2exp(level)] , respectively.

Parameters:

level - The stride level to apply when seeking elevation value.

line - The line index in the array.

column - The column index in the array.

Returns:

The elevation value.

getTileWidth

int getTileWidth()

Returns the number of columns in this IlvTileElevationProvider.

Returns:

The number of columns.

getTileHeight

int getTileHeight()

Returns the number of lines in this IlvTileElevationProvider;

Returns:

The number of lines.
