| WingImage | | public class WingImage (Code) | | This class extends functionality of java.awt.Image.
WingImage contains java.awt.Image object as
source image and following parameters describing how the image is rendered.
- source rectangle - describing used area of source image,
- optional stretch insets - describing stretch margin,
- optional tile mode - telling if the image is stretched or tiled,
- optional alpha - making the image transparent as a whole
This is one of the core WingS classes required by all the components
This class is thread safe.

| WingImage | | public WingImage(WingImage image, int part, int width, int height)(Code) | | Creates a new WingImage
calculating source rectangle in the following way:
area of the source image is threat as a grid with the specified
cell size, the source rectangle is an area covering specified
cell of the grid counting from the top left corner
All other properties are derived from the source image

image - source image
Parameters:
part - grid cell number
Parameters:
width - grid cell width
Parameters:
height - grid cell height |
| WingImage | | public WingImage(WingImage image)(Code) | | Creates a new WingImage using the whole area of the source image
All other properties are derived from the source image
Parameters:
image - source image |
