GpxLayer

public GpxLayer(GpxData d,
                java.lang.String name,
                boolean isLocal)

Method Detail

getTimespanForTrack

private static java.lang.String getTimespanForTrack(GpxTrack trk)

returns a human readable string that shows the timespan of the given track

getIcon

public javax.swing.Icon getIcon()

Description copied from class: Layer

Return a representative small image for this layer. The image must not be larger than 64 pixel in any dimension.

Specified by:

getIcon in class Layer

getInfoComponent

public java.lang.Object getInfoComponent()

Specified by:

getInfoComponent in class Layer

getColor

public java.awt.Color getColor(boolean ignoreCustom)

Description copied from class: Layer

Return a Color for this layer. Return null when no color specified.

Overrides:

getColor in class Layer

Parameters:

ignoreCustom - Custom color should return null, as no default color is used. When this is true, then even for custom coloring the base color is returned - mainly for layer internal use.

getColorMode

public GpxLayer.colorModes getColorMode()

getGenericColor

public static java.awt.Color getGenericColor()

getMenuEntries

public javax.swing.Action[] getMenuEntries()

Description copied from class: Layer

Returns list of actions. Action can implement LayerAction interface when it needs to be represented by other menu component than JMenuItem or when it supports multiple layers. Actions that support multiple layers should also have correct equals implementation. Use SeparatorLayerAction.INSTANCE instead of new JSeparator

Specified by:

getMenuEntries in class Layer

getToolTipText

public java.lang.String getToolTipText()

Specified by:

getToolTipText in class Layer

Returns:

A small tooltip hint about some statistics for this layer.

isMergable

public boolean isMergable(Layer other)

Specified by:

isMergable in class Layer

Parameters:

other - The other layer that is tested to be mergable with this.

Returns:

Whether the other layer can be merged into this layer.

sumUpdateCount

private int sumUpdateCount()

isChanged

public boolean isChanged()

Description copied from class: Layer

Check changed status of layer

Overrides:

isChanged in class Layer

Returns:

True if layer was changed since last paint

mergeFrom

public void mergeFrom(Layer from)

Description copied from class: Layer

Merges the given layer into this layer. Throws if the layer types are incompatible.

Specified by:

mergeFrom in class Layer

Parameters:

from - The layer that get merged into this one. After the merge, the other layer is not usable anymore and passing to one others mergeFrom should be one of the last things to do with a layer.

w

private static float w(float x)

transition function: w(0)=1, w(1)=0, 0<=w(x)<=1

Parameters:

x - number: 0<=x<=1

Returns:

the weighted value

paint

public void paint(java.awt.Graphics2D g,
                  MapView mv,
                  Bounds box)

Description copied from class: Layer

Paint the dataset using the engine set.

Specified by:

Specified by:

paint in class Layer

mv - The object that can translate GeoPoints to screen coordinates.

                         GpxLayer.Markers markers)

Makes a new marker layer derived from this GpxLayer containing at least one audio marker which the given audio file is associated with. Markers are derived from the following (a) explict waypoints in the GPX layer, or (b) named trackpoints in the GPX layer, or (d) timestamp on the wav file (e) (in future) voice recognised markers in the sound recording (f) a single marker at the beginning of the track

Parameters:

wavFile - : the file to be associated with the markers in the new marker layer

markers - : keeps track of warning messages to avoid repeated warnings
