How do I put an image on a canvas?

[Carlos Failde]

I have put a canvas on an applet and want to add a gif image to the canvas.
I know to put an image on an applet you'd use something like
Image I= getImage(getCodeBase(), "image.gif");
g.drawImage(I, x,y,width, height, this);
but I can't figure out how to add an image to my canvas.

This thread may help with your question. Basically, you will have to subclass the canvas and override its paint() method. You should be careful if you are mixing a canvas with any Swing components because you can get wierd results, as mentioned in the above thread. In that case, you can use a JPanel for drawing instead.

You simply have to get the Graphics instance from the Canvas and draw using that. It should look something like this

Canvas c = new Canvas( ... );
add( c );
// Usually called from the applet's paint method in order
// to make sure that the Canvas has a valid peer and will
// return a valid Graphics object
Graphics canvasG = c.getGraphics();
Image I = getImage(getCodeBase(), "image.gif");
canvasG.drawImage(I, x, y, width, height, this);
c.repaint();

Hope this helps.
