| SWT's Image class can be used to display images in a GUI. The |
| most common source of images is to load from a standard file |
| format such as GIF, JPEG, PNG, or BMP. Some controls, including |
| Buttons and TreeItems, are able to display an Image directly |
| through the setImage(Image) method, but any control's paint |
| event allows images to be drawn through the callback's graphic |
| context. SWT's ImageData class represents the raw data making up |
| an SWT Image and determines the color for each pixel coordinate. |
| This article shows the correct uses of ImageData and Image, |
| shows how to load images from files, and how to achieve graphic |
| effects such as transparency, alpha blending, animation, |
| scaling, and custom cursors. |
