All Implemented Interfaces:

public class PJABufferedImage

extends BufferedImage

Pure Java AWT BufferedImage implementation.

When drawing in images of class java.awt.image.BufferedImage, .pjaf font files are not used (other fonts already exist).
java.awt.image.BufferedImage and thus PJABufferedImage classes require awt library loading. Java2D can work with PJA only with JVM version >= 1.2.

Since:

PJA2.0

Method Detail

createGraphics

public Graphics2D createGraphics()

Returns an instance of Graphics2D to draw in the image. createGraphics (); returns the Graphics instance returned by the method createGraphics () of PJAGraphicsEnvironment class, if super.createGraphics () failed because for exemple it was impossible to change java.awt.graphicsenv system property.

Overrides:

createGraphics in class BufferedImage

getSubimage

public BufferedImage getSubimage(int x,
                                 int y,
                                 int w,
                                 int h)

Overriden to return an instance of PJABufferedImage.

Overrides:

getSubimage in class BufferedImage
