Constructor Detail

RotateTextEphemeron

public RotateTextEphemeron(XyPoint anchor,
                           java.lang.String text,
                           java.lang.String textStyle,
                           double textPixelWidth)

Spins passed text around fixed point. Just as rotation ephemeron does with lines.

Uses passed pixel width as length of word.

Parameters:

anchor - - XyPoint to be used for pivot.

text - - text to be drawn.

textStyle - - text style to use for text.

textPixelWidth - - Pixel width of text to be drawn.

RotateTextEphemeron

public RotateTextEphemeron(MapApp app,
                           MapSet mapset,
                           XyPoint anchor,
                           java.lang.String text,
                           java.lang.String textStyle)

Spins passed text around fixed point. Just as rotation ephemeron does with lines.

This constructor attempts to calculate the text style's pixel width. If none can be found, 8 pixels per character is used.

Parameters:

app - - MapApp, used to calculating text width.

mapset - - MapSet where these styles live.

anchor - - XyPoint to be used for pivot.

text - - text to be drawn.

textStyle - - text style to use for text.

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).
