So in short:

var image  := TW3Image.Create(self);
//create temp graphic and canvas to draw on
var graph  := TW3GraphicContext.Create(NIL);
graph.Allocate(image.Width, image.Height);
var canvas := TW3Canvas.Create(graph);
// Draw some text on the canvas
canvas.font:='10pt verdana';
canvas.FillStyle:='rgb(255,255,255)';
canvas.FillTextF('This was generated on a canvas!',10,20,MAXINT);
//You can load it in as a picture
image.LoadFromUrl(canvas.toDataUrl(''));
