drawPage

public void drawPage(Page page)

Description copied from interface: OutputDisplay

Draws the complete page including all the boxes.

Specified by:

drawPage in interface OutputDisplay

Parameters:

page - The page to draw.

drawPage

public void drawPage(Page page,
                     boolean bitmap)

Description copied from interface: OutputDisplay

Draws the complete page by drawing all the boxes or a bitmap screenshot.

Specified by:

drawPage in interface OutputDisplay

Parameters:

page - The page to draw.

bitmap - Use bitmap page screen shot if available.

drawBox

public void drawBox(Box box)

Description copied from interface: OutputDisplay

Draws the box contents on the page depending on the box type. This does not automatically draw the child boxes.

Specified by:

drawBox in interface OutputDisplay

Parameters:

box - The box do draw.

drawExtent

public void drawExtent(Box box)

Description copied from interface: OutputDisplay

Draws the box bounds at the output display.

Specified by:

drawExtent in interface OutputDisplay

Parameters:

box - The box to be displayed

drawExtent

public void drawExtent(Area area)

Description copied from interface: OutputDisplay

Draws the area bounds at the output display.

Specified by:

drawExtent in interface OutputDisplay

Parameters:

area - The area to be displayed

drawRectangle

public void drawRectangle(Rectangular rect,
                          Color color)

Description copied from interface: OutputDisplay

Draws the given rectangle with the specified color.

Specified by:

drawRectangle in interface OutputDisplay

Parameters:

rect - the rectangle to be drawn

color - the drawing color

drawConnection

public void drawConnection(ContentRect a1,
                           ContentRect a2,
                           Color color)

Description copied from interface: OutputDisplay

Draws a connection between two content rectangles.

Specified by:

drawConnection in interface OutputDisplay

Parameters:

a1 - The first content rectangle

a2 - The second content rectangle

color - Connection color

colorizeByTags

public void colorizeByTags(ContentRect rect,
                           Set<Tag> s)

Description copied from interface: OutputDisplay

Draws the colorized are bounds. The color is defined by the tags. Multiple colors should be used when there are multiple tags (e.g. splitting the area bounds to several parts). The output display should assign different colors to different tags; the exact implementation of the color mapping depends on the OutputDisplay implementation. The area is not displayed when the tag set is empty.

Specified by:

colorizeByTags in interface OutputDisplay

Parameters:

rect - The area to be displayed

s - A set of tags used for generating the area colors

clearArea

public void clearArea(int x,
                      int y,
                      int width,
                      int height)

Description copied from interface: OutputDisplay

Clears the given area of the display.

Specified by:

clearArea in interface OutputDisplay

Parameters:

x - the area X coordinate

y - the area Y coordinate

width - the area width

height - the area height

colorizeByClass

public void colorizeByClass(ContentRect rect,
                            String cname)

Description copied from interface: OutputDisplay

Draws the colorized are bounds. The color is defined by a string. The output display should assign different colors to different strings; the exact implementation of the color mapping depends on the OutputDisplay implementation. The area is not displayed when class name is empty.

Specified by:

colorizeByClass in interface OutputDisplay

Parameters:

rect - The area to be displayed

cname - The class name used for generating the colors.

setupGraphics

protected void setupGraphics()

Configures the graphics context for drawing the boxes. This method is normally called from drawPage(Page) before the actual drawing starts.

stringColor

protected Color stringColor(String cname)
