Class ScreenBoth

          org.razvan.jzx.BaseScreen
              org.razvan.jzx.ScreenBoth

All Implemented Interfaces:

java.awt.image.ImageObserver, java.awt.MenuContainer, java.io.Serializable, javax.accessibility.Accessible

public class ScreenBoth
extends BaseScreen

Screen implementation that runs in both JDK1.1 and JDK1.2 VMs, but is optimized for neither.

This implementation uses a MemoryImageSource, and calls the method newPixels() to indicate that new data is available for drawing into the image.

Method Detail

init

public void init(BaseSpectrum spectrum,
                 ILogger logger)

Allocate the RGB data array and the MemoryImageSource object that Decorates the data.

Overrides:

init in class BaseScreen

setScale

protected void setScale(int scale)

Update the RGB data array and the MemoryImageSource for the new scale value.

Overrides:

setScale in class BaseScreen

paint

public void paint(java.awt.Graphics g)

draw8

protected void draw8(int x,
                     int y,
                     int pix8,
                     int attr8)

Draw a given byte into the RGB array using the given attribute, at the given location.

Specified by:

draw8 in class BaseScreen

Parameters:

x - The X coordinate where the pixels should be drawn onto the Canvas object.

y - The Y coordinat where the pixels should be drawn onto the Canvas object.

pix8 - The 8 bits to draw starting at (X,Y) ending at (X+8,Y).

attr8 - The attributes used to draw the 8 bits.

endRender

protected void endRender()
