Class ByteImage

java.lang.Object
org.opensourcephysics.display.ByteImage
All Implemented Interfaces:
Drawable, Measurable
public class ByteImage extends Object implements Measurable
A ByteImage contains an array of bytes int[row][col] where each integer represents an image pixel. The row index determines the y-location of the pixel and the col index determines the x-location in the drawing panel.
