Class OutputWindow

java.lang.Object
  core.io.OutputWindow

public class OutputWindow

extends java.lang.Object

An RGB frame-buffer accessible window = < title, width, height, byte-buffer >. On construction, a window with the specified width, height, and title appears. This window can be drawn to via Raster or Graphics operations, or its contents can be accessed directly via an RGB byte-buffer. Since the window contents are effectively double-buffered, an explicit call to Refresh() is required to update the window.

Constructor Detail

OutputWindow

public OutputWindow(java.lang.String Title,
                    int Width,
                    int Height)

Consturcts a new OutputWindow = < Title, Width, Height, zero-buffer >. Because of AWT inconsistencies, it uses an ugly hack... appears to work well on Windows, but not so well on UNIX.

Method Detail

SetSize

public void SetSize(int Width,
                    int Height)

Sets the size of the window to (Width, Height)

SetTitle

public void SetTitle(java.lang.String Title)

Changes the title of the window to 'Title'

dispose

public void dispose()

Refresh

public void Refresh()

Draws the back-buffer contents to the screen

getBufferedGraphics

public java.awt.Graphics getBufferedGraphics()

Returns: a Graphics object that can be used to draw on the back-buffer

getRaster

public java.awt.image.WritableRaster getRaster()

Returns: a WritableRaster that cna be used to draw to the back-buffer

getByteBuffer

public byte[] getByteBuffer()

Returns: a byte array that contains the contents of the back-buffer. The pixels are stored in scanline order in packed RGB byte-components.
