Method Detail

getWidth

int getWidth()

Gets the raster's width.

Returns:

the raster's width

getHeight

int getHeight()

Gets the raster's height.

Returns:

the raster's height

getSamples

boolean getSamples(int[] x,
                   int[] y,
                   double[][] samples)
            throws Exception

Gets the sample value at the given raster position or Float.NaN.

Parameters:

x - the pixel's X-coordinate

y - the pixel's Y-coordinate the sample value or Double.NaN if data is missing at the given raster position
