Java2DRenderer (MultimediaLib 2020.2 API)

java.lang.Object
- nl.colorize.multimedialib.renderer.AbstractRenderer
- - nl.colorize.multimedialib.renderer.java2d.Java2DRenderer

All Implemented Interfaces:

Renderer

Direct Known Subclasses:

HeadlessRenderer
```
public class Java2DRenderer
extends AbstractRenderer
```
Implementation of a renderer that uses APIs from the Java standard library. Graphics are displayed using Java 2D, AWT is used to create windows and capture keyboard events, and Java Sound is used to play audio.
The renderer will use two different threads: the rendering thread is used to update the graphics, while the Swing thread is used to listen for user input.

Java2DRenderer

public Java2DRenderer(Canvas canvas,
                      int framerate,
                      WindowOptions windowOptions)

Method Detail
- initializeWindow
```
protected javax.swing.JFrame initializeWindow(WindowOptions windowOptions)
```
- prepareCanvas
```
protected void prepareCanvas()
```
- prepareWindowBuffer
```
protected java.awt.image.BufferStrategy prepareWindowBuffer()
```
  Prepares the window buffer for the current frame. This buffer will be used to display the graphics once the entire frame has been rendered.
- blitGraphicsContext
```
protected void blitGraphicsContext(java.awt.image.BufferStrategy windowBuffer)
```
  Updates the window graphics with the contents of the buffer.
- getInputDevice
```
public InputDevice getInputDevice()
```
- getMediaLoader
```
public MediaLoader getMediaLoader()
```
- getApplicationData
```
public ApplicationData getApplicationData(java.lang.String appName)
```
- getInternetAccess
```
public InternetAccess getInternetAccess()
```
- takeScreenshot
```
public java.lang.String takeScreenshot()
```
  Description copied from interface: Renderer
  
  Takes a screenshots of the renderer's current graphics, and saves it to an image. The image is returned as a data URL for a PNG image.
- terminate
```
public void terminate()
```
