Method Detail

computeScenePos

public static Point2D.Double computeScenePos(ProductSceneView view,
                                             int x,
                                             int y)

Compute the scene position according to the view raster

Parameters:

view - the current view

x - the current pixel's X coordinate

y - the current pixel's Y coordinate

Returns:

the scene position

getPixelValue

public static String getPixelValue(Point2D.Double scenePos,
                                   RasterDataNode raster)

Get the pixel value for the current raster

Parameters:

scenePos - the scene position (in another raster)

raster - the current raster for which we want to find the pixel value

Returns:

the pixel value for the current raster
