The saying a blank canvas is very similar to what a Canvas object is on Android In an earlier tutorial we covered how to draw a pie chart or doughnut chart using HTML5 canvas.In this tutorial I will show you how to use JavaScript and the HTML5 canvas as a means to graphically display data by using bar charts

Since the canvas will be using the buttons to control what it draws, it will be the canvas that will be the listener On the other hand, it is the applet that should lay out these components (since they are being laid out on the applet's surface), and thus the applet creates the buttons and passes them to the LineCanvas constructor The Canvas API is actually a JavaFX node called the Canvas class. Since the Canvas class extends from javafx.scene.Node class, it is basically a scene graph node like any other JavaFX node, except you have the ability to draw directly and manipulate pixel data using graphics primitives (Canvas API) onto the surface (GraphicsContext) this is why i am putting the image first into a Canvas, with the background color set, and the target dimension set for the Canvas. Now I need to get the Image in the Canvas. If I get it clear you just want to resize an existing image, right? Then drop the Canvas - use BufferedImage instead

Now we can start playing with those pixels! Updating the image data. The image data on the canvas allows us to manipulate and change the pixels. The data property is an ImageData object with three properties — the width, height and data/ all of which represent those things based on the original image. All these properties are readonly.The one we care about is data, n one-dimensional array. The java.awt.Graphics Class: Graphics Context and Custom Painting.
