Method Detail

getGraphics

Graphics2D getGraphics()

drawPage

void drawPage(Page page)

Draws the complete page including all the boxes.

Parameters:

page - The page to draw.

drawPage

void drawPage(Page page,
              boolean bitmap)

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

Parameters:

page - The page to draw.

bitmap - Use bitmap page screen shot if available.

drawBox

void drawBox(Box box)

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

Parameters:

box - The box do draw.

drawExtent

void drawExtent(Box box)

Draws the box bounds at the output display.

Parameters:

box - The box to be displayed

drawExtent

void drawExtent(Area area)

Draws the area bounds at the output display.

Parameters:

area - The area to be displayed

drawRectangle

void drawRectangle(Rectangular rect,
                   Color color)

Draws the given rectangle with the specified color.

Parameters:

rect - the rectangle to be drawn

color - the drawing color

drawConnection

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

Draws a connection between two content rectangles.

Parameters:

a1 - The first content rectangle

a2 - The second content rectangle

color - Connection color

colorizeByTags

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

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.

Parameters:

rect - The area to be displayed

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

colorizeByClass

void colorizeByClass(ContentRect rect,
                     String cname)

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.

Parameters:

rect - The area to be displayed

cname - The class name used for generating the colors.

clearArea

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

Clears the given area of the display.

Parameters:

x - the area X coordinate

y - the area Y coordinate

width - the area width

height - the area height
