Constructor Detail

ScaleSnapshotEphemeron

public ScaleSnapshotEphemeron(MapViewFrame snapshot,
                              java.lang.String cornerName)

Creates a new ScaleSnapshotEphemeron for a snapshot represented by the passed MapViewFrame

Parameters:

snapshot - - MapViewFrame representing snapshot

Method Detail

mangleSnapshot

protected void mangleSnapshot(DrawingSurface surface,
                              MapViewFrame frame,
                              XyPoint mousePosition)

Description copied from class: AbstractSnapshotEphemeron

Changes internal snapshot before each draw.

Handles specific ephemera changes. Allows rotating,scaling, and moving ephemera to share draw code. Does not need to reset the MapViewFrame's transform.

Specified by:

mangleSnapshot in class AbstractSnapshotEphemeron

draw

public void draw(DrawingSurface surface,
                 MapViewFrame frame,
                 XyPoint mousePosition)

Description copied from interface: Ephemeron

Draw appropriate graphics on the given surface with the given frame, mouse position, and any implementation-specific internal state. The drawing surface is set up with the given frame, and is in map coordinates (not pixels).

Specified by:

draw in interface Ephemeron
