codedraw.CodeDraw

public class CodeDraw extends Object

CodeDraw is an easy-to-use drawing library where you use code to create pictures and animations. It is made for beginners that understand little about programming and makes it very simple to draw and animate various shapes and images to a canvas.

You can view the CodeDraw repository here.
To get a brief overview and a bunch of examples visit the README of the CodeDraw repository.
Read the introduction to CodeDraw for a beginners guide to CodeDraw.

An example to get you started:


 import codedraw.*;

 public class MyProgram {
     public static void main(String[] args) {
         // Creates a new CodeDraw window with the size of 600x600 pixel
         CodeDraw cd = new CodeDraw();

         // Sets the drawing color to red
         cd.setColor(Palette.RED);
         // Draws the outline of a rectangle
         cd.drawRectangle(100, 100, 200, 100);
         // Draws a filled Square
         cd.fillSquare(180, 150, 80);

         // Changes the color to light blue
         cd.setColor(Palette.LIGHT_BLUE);
         cd.fillCircle(300, 200, 50);

         // Finally, the method show must be called
         // to display the drawn shapes in the CodeDraw window.
         cd.show();
     }

- saveCanvas
  
  public BufferedImage saveCanvas()
  Creates a copy of the current buffer (not the displayed image) and returns it as a buffered image. A BufferedImage can be saved as a file with the following code:
  CodeDraw cd = new CodeDraw(); // some drawing occurs here try { ImageIO.write( cd.saveCanvas(), "png", new File("C:\\pathToDirectory\\filename.png") ); } catch (IOException e) { throw new UncheckedIOException(e); }
  Fun Fact: You can copy the currently displayed canvas to your clipboard by pressing Ctrl + C
  .
  Returns:
  
  The current buffer as an image object.
- clear
  
  public void clear()
  
  Colors the whole canvas in white.
- clear
  
  public void clear(Color color)
  
  Colors the whole canvas in the color given as a parameter.
  
  Parameters:
  
  color - The color the canvas will be colored in.
- show
  
  public void show()
  
  Displays the drawn shapes and images on the canvas. Calling show while executing an event is generally not recommended because rendering is slow and this will slow down you program. Instead, you should call show from the main thread.
- show
  
  public void show(int waitMilliseconds)
  
  Displays the drawn shapes and images on the canvas and then waits for the given amount of milliseconds. The copying of the buffer to the screen also takes a bit of time and that will be the minimum time it takes for this method to return.
  The amount of milliseconds this method must be called with to display a certain amount of frames per second:
  30 fps ~ 33ms
  60 fps ~ 16ms
  120 fps ~ 8ms
  Calling show or sleeping while executing an event will block all other events from executing. It is generally not recommended. Instead, you should call show from the main thread.
  
  Parameters:
  
  waitMilliseconds - Minimum time it takes this function to return.
- dispose
  
  public void dispose()
  
  Closes the frame and disposes all created resources associated with this CodeDraw instance. Terminates the process when all CodeDraw instances are closed. To prevent termination pass false to this function. See dispose(boolean).
- dispose
  
  public void dispose(boolean exit)
  
  Closes the frame and disposes all created resources associated with this CodeDraw instance.
  
  Parameters:
  
  exit - When true terminates the process when all CodeDraw instances are closed. When false lets the process continue even though all CodeDraw instances have been closed.
- toString
  
  public String toString()
  
  Overrides:
  
  toString in class Object
