Method Summary

Modifier and Type	Method and Description
void	draw(Graphics g, int x, int y, Rect destArea, double xdpi, double ydpi, int options) Draw this point image to the Graphics at the specified location, assuming that the Graphics is drawing on a surface with the specified x and y dpis.
void	draw(PointGraphics g, double x, double y, PointRect destArea, int options) Draw the PointImage to the PointGraphics, specifying the destination area that is to be drawn on the PointGraphics - all other sections of the image will be clipped.

                         double height)

Method Detail

getPointWidth

public double getPointWidth()

Description copied from interface: IPointImage

Return the width of the PointImage in points.

Specified by:

getPointWidth in interface IPointImage

getPointHeight

public double getPointHeight()

draw

public void draw(PointGraphics g,
                 double x,
                 double y,
                 PointRect destArea,
                 int options)

Description copied from interface: PointImage

Draw the PointImage to the PointGraphics, specifying the destination area that is to be drawn on the PointGraphics - all other sections of the image will be clipped.

Specified by:

draw in interface PointImage

Parameters:

g - the destination PointGraphics.

x - the x location where the top left corner of the PointImage would be if the entire image was drawn.

y - the y location where the top left corner of the PointImage would be if the entire image was drawn.

destArea - the destination area being updated on the PointGraphics. Only this area will be drawn.

options - draw options - none are currently defined.

draw

public void draw(Graphics g,
                 int x,
                 int y,
                 Rect destArea,
                 double xdpi,
                 double ydpi,
                 int options)

Description copied from interface: IPointImage

Draw this point image to the Graphics at the specified location, assuming that the Graphics is drawing on a surface with the specified x and y dpis.

Specified by:

draw in interface IPointImage

Parameters:

g - the Grahics to draw on.

x - the x pixel location on the Graphics that represents the top left of the PointImage.

y - the y pixel location on the Graphics that represents the top left of the PointImage.

destArea - the destination area of the Graphics that is to be updated.

xdpi - the xdpi of the Graphics.

ydpi - the ydpi of the Graphics.

options - options for the draw. None are defined yet.

getPixels

public void getPixels(PixelBuffer dest,
                      int x,
                      int y,
                      Rect destArea,
                      double xdpi,
                      double ydpi,
                      int options)

Description copied from interface: IPointImage

The PixelBuffer size must be at least as big as the destArea. The PixelBuffer 0,0 co-ordinates will equate to the destArea.x and destArea.y co-ordinates.

Specified by:

getPixels in interface IPointImage
