TLcdVVTerrainProfileRenderer

public TLcdVVTerrainProfileRenderer()

Method Details

setAltitudeFormat

public void setAltitudeFormat(Format aAltitudeFormat)

Set the format used to display altitude values.

Parameters:

aAltitudeFormat - the format used to display altitude values.

See Also:

• getAltitudeFormat()

getAltitudeFormat

public Format getAltitudeFormat()

Gets the format used to display altitude values.

Returns:

the format used to display altitude values.

See Also:

• setAltitudeFormat(java.text.Format)

fillSubProfileStepPolygon

public void fillSubProfileStepPolygon(Graphics aGraphics,
 TLcdVVJPanel aVView,
 int aState,
 int aRenderingMode,
 int aSubProfileStepIndex,
 int aSegmentIndex,
 int aSubProfileIndex,
 int[] aXArray,
 int[] aYArray)

This method actually paints the terrain profile.

Specified by:

fillSubProfileStepPolygon in interface ILcdVVRenderer

Overrides:

fillSubProfileStepPolygon in class TLcdDefaultVVRenderer

Parameters:

aGraphics - The graphics to paint on.

aState - Not used yet

aRenderingMode - See constants defined in this interface

aSubProfileStepIndex - The segment-index of the subprofile. Can go from zero until ILcdVVModel.subProfilePointCount(int, int) - 2.

aSegmentIndex - The segment index within the main-profile.

aSubProfileIndex - The index of the sub-profile.

aXArray - An array of int that contains the X-values of the points of the polygon in clockwise direction.

aYArray - An array of int that contains the Y-values of the points of the polygon in clockwise direction.

paintPointLabel

public void paintPointLabel(Graphics aGraphics,
 TLcdVVJPanel aVView,
 int aPointIndex,
 int xPos,
 int yPos)

Paints the labels for the main profile points.

Specified by:

paintPointLabel in interface ILcdVVRenderer

Overrides:

paintPointLabel in class TLcdDefaultVVRenderer

Parameters:

aGraphics - the graphics to paint label of the point on.

xPos - the X-coordinate of the point.

yPos - the Y-coordinate of the point.

paintVerticalCursor

public void paintVerticalCursor(Graphics aGraphics,
 TLcdVVJPanel aVView,
 int aCurrentXPosition,
 int aYOffset,
 int aHeight,
 int aLeftPointIndex,
 int aRightPointIndex,
 int aMouseY,
 double aRatio)

Paints the vertical cursor. This is the red line which follows the mouse over the terrain profile when the left mouse buttons is pressed and indicates the terrain level at the cursor position.

Specified by:

paintVerticalCursor in interface ILcdVVRenderer

Overrides:

paintVerticalCursor in class TLcdDefaultVVRenderer

Parameters:

aGraphics - the graphics to paint the vertical cursor on.

aCurrentXPosition - The position on aGraphics where the cursor should be drawn.

aYOffset - The position indicating the top Y position for the cursor.

aHeight - The amount of pixels in the Y dimension.

aLeftPointIndex - The main profile point on the left of the cursor.

aRightPointIndex - The main profile point on the right of the cursor.

aMouseY - The Y value indicating where the mouse was last located (while dragging of the cursor occurred). Can be useful for painting the label on the cursor. Will be -1 if no dragging has appeared yet.

aRatio - If the total delta between left and right point is 1, then this ratio indicates the cursor's new position relative to the first point.

setUnknownColor

public void setUnknownColor(Color aUnknownColor)

Sets the color to use to display unknown altitudes. The default value is red.

Parameters:

aUnknownColor - the color to use to display unknown altitudes.

See Also:

• getUnknownColor()

getUnknownColor

public Color getUnknownColor()

Returns the color used to display unknown altitudes. The default value is red.

Returns:

the color used to display unknown altitudes.

See Also:

• setUnknownColor(Color)

isValidElevation

protected boolean isValidElevation(double aElevationValue)

Checks whether the given elevation value is a known value as returned by the terrain elevation provider. This method returns false if the elevation value is Double.NaN, Double.POSITIVE_INFINITY or Double.NEGATIVE_INFINITY.

Parameters:

aElevationValue - the elevation value to check.

Returns:

true for known values, false for the unknown values.
