Constructor Details

DataReferenceOverlay

public DataReferenceOverlay(Color color,
 int layer,
 Stroke stroke,
 boolean manualLines,
 double[] rows,
 double[] cols,
 boolean drawLabels,
 Font font)

Constructs a new grid overlay.

Parameters:

color - the overlay color.

layer - the overlay layer number.

stroke - the stroke to use for vector paths.

manualLines - the manual lines flag.

rows - the reference row line values.

cols - the reference column line values.

drawLabels - the grid labels flag, true if grid labels should be drawn.

font - the grid labels font. The labels font may be null if no labels are to be drawn.

DataReferenceOverlay

public DataReferenceOverlay(Color color)

Constructs a new grid overlay. The layer number is initialized to 0, the stroke to the default BasicStroke, the manual lines flag to false, labels to true, and the font to the default font face, plain style, 12 point.

Parameters:

color - the overlay color.

Method Details

setManualLines

public void setManualLines(boolean flag)

Sets the manual grid lines flag. When off, the grid lines are calculated automatically at rendering time for an optimal number of grid lines in both the rows and columns directions.

getManualLines

public boolean getManualLines()

Gets the manual grid increment mode flag.

setRows

public void setRows(double[] rows)

Sets the reference row lines.

getRows

public double[] getRows()

Gets the current reference row lines.

setCols

public void setCols(double[] cols)

Sets the reference row lines.

getCols

public double[] getCols()

Gets the current reference row lines.

getLines

protected LineCollection getLines(EarthDataView view)

Description copied from class: LabeledLineOverlay

Gets the collection of lines for this overlay. This method should be implemented by the subclass and is called by LabeledLineOverlay.prepare(java.awt.Graphics2D, noaa.coastwatch.render.EarthDataView).

Specified by:

getLines in class LabeledLineOverlay

Parameters:

view - the earth view for line rendering.

Returns:

the collection of lines to render.

main

public static void main(String[] argv)

Tests this class.

Parameters:

argv - the array of command line parameters.
