Java Code House

Today I am going to post a program that will use a text string as a clipping path and draw an image with it. As you know, Graphics2D can do a number of operations like transformations,clipping and alpha compositing. Here in our case, we will use images. First of all we will rotate the user space. This is just to give our output a more better look. The clipping shape is created in the method getClippingShape(Graphics) method. Here a text is chosen and a Font instance is created. This font is used to create GlyphVector for the clipping shape string. Then the shape is retrieved by calling getOutline() method of GlyphVector. The clip method of Graphics2D is called, followed by reading of the image from file using ImageIO's read method. Finally the image is drawn on panel and displayed.
