java graphics2d example

The Java language, on the basis of the graphics class, provides a variety of basic geometries, extending the graphics class to provide a graphics2d class with more powerful two-dimensional graphics processing capabilities, providing more precise control of coordinate transformations, color management, and text layout.Drawing Properties Graphics2D defines several

You can set this attribute by calling setComposite:Public abstract void setComposite (Composite comp) For example, fir

Java programmers. In this case, it seems simple to use a pbuffer to render the object, because we can use the same framework as the Java graphics2d, as long as it is slightly modified to draw to pbuffer (a picture outside of the screen in memory). Such a picture can then be retrieved as a standard bufferedimage, and the bufferedimage can be copied to the screen.
