Method Detail

getGraphics

public Graphics2D getGraphics()

Description copied from interface: FigGraphics

Retrieves Graphics property.

Specified by:

getGraphics in interface FigGraphics

Returns:

current property value

setGraphics

public void setGraphics(Graphics2D iGraphics)

Description copied from interface: FigGraphics

Updates Graphics property.

Details: FigGraphics.setGraphics(Graphics2D) sets the Graphics property to the supplied value. Extreme care should be taken when using this method, because other Doodles may subsequently use this FigGraphics instance.

Specified by:

setGraphics in interface FigGraphics

getView

public FigureView getView()

Description copied from interface: FigGraphics

Retrieves View property.

Specified by:

getView in interface FigGraphics

Returns:

current property value

getDetailLevel

public DetailLevel getDetailLevel()

Description copied from interface: FigGraphics

Retrieves DetailLevel property.

Specified by:

getDetailLevel in interface FigGraphics

Returns:

current property value

getScale

public double getScale()

Description copied from interface: FigGraphics

Computes rendering scale.

Details: FigGraphics.getScale() computes and returns the magnification at which the figure will be rendered, when using this drawing context.

Sophisticated Doodle implementations may use this property to adjust the level of detail at which they are rendered, or perhaps even to decide whether they should be rendered at all. For example, a text Doodle may choose not to draw itself if it will be too small to read.

Specified by:

getScale in interface FigGraphics

Returns:

the magnification

getRotation

public double getRotation()

Description copied from interface: FigGraphics

Computes rendering angle.

Details: FigGraphics.getRotation() computes and returns the rotation angle at which the figure will be rendered, when using this drawing context.

Sophisticated Doodle implementations may use this property to adjust their own drawing angle, so that the Doodle can be viewed at the same angle regardless of the view. For example, text Doodles may be rendered horizontally regardless of the view's rotation.

Specified by:

getRotation in interface FigGraphics

Returns:

rendering angle

drawOnTop

public void drawOnTop(Doodle iDoodle,
             AffineTransform iTransform)

Description copied from interface: FigGraphics

Schedules deferred drawing.

Details: This method schedules the given Doodle to be drawn after all of the other Doodles in the Figure. The Doodle will be drawn using the supplied transform. Drawing is scheduled on a first-queued, first-drawn basis. The Z-orders of Doodles scheduled for drawing are ignored.

Specified by:

drawOnTop in interface FigGraphics

Parameters:

iDoodle - Doodle to draw

iTransform - graphics transform for drawing Doodle
