Class TLcdRasterMatrix

java.lang.Object
com.luciad.tea.TLcdRasterMatrix
All Implemented Interfaces:
ILcdMatrixView, ILcdMatrix
public class TLcdRasterMatrix extends Object implements ILcdMatrix, ILcdMatrixView

A TLcdRasterMatrix is an ILcdMatrix wrapper around a part of an ILcdRaster. This implementation assumes that the bounds and all rasters have the same model reference.

The implementation of the ILcdMatrix interface is for backward compatibility.

  • Constructor Details

    • TLcdRasterMatrix

      public TLcdRasterMatrix(ILcdRaster aRaster, ILcdBounds aBounds, int aXLength, int aYLength)
      Construct a new raster matrix for the specified raster. The bounds argument is used to find the associated points of the matrix view.
      Parameters:
      aRaster - The raster to be used.
      aBounds - The bounds of the raster.
      aXLength - The column count.
      aYLength - The row count.

    • TLcdRasterMatrix

      public TLcdRasterMatrix(ILcdRaster[] aRasters, ILcdBounds aBounds, int aXLength, int aYLength)
      Construct a new raster matrix for the specified rasters. The bounds argument is used to find the associated points of the matrix view.
      Parameters:
      aRasters - The array of rasters to be used.
      aBounds - The bounds of the rasters.
      aXLength - The column count.
      aYLength - The row count.
