Method Details

getSize

protected Point getSize()

Description copied from class: CompositeImageDescriptor

Return the size of this composite image.

Subclasses must implement this framework method.

Specified by:

getSize in class CompositeImageDescriptor

Returns:

the x and y size of the image expressed as a point object

drawCompositeImage

protected void drawCompositeImage(int width,
 int height)

Description copied from class: CompositeImageDescriptor

Draw the composite images.

Subclasses must implement this framework method to paint images within the given bounds using one or more calls to the CompositeImageDescriptor.drawImage(ImageDataProvider, int, int) framework method.

Implementers that need to perform computations based on the size of another image are advised to use one of the CompositeImageDescriptor.createCachedImageDataProvider(org.eclipse.swt.graphics.Image) methods to create a CompositeImageDescriptor.CachedImageDataProvider that can serve as ImageDataProvider. The CompositeImageDescriptor.CachedImageDataProvider offers other interesting methods like getWidth() or computeInPoints(...) that can be useful to compute values in points, based on the resolution-dependent ImageData that is applicable for the current drawing operation.

Specified by:

drawCompositeImage in class CompositeImageDescriptor

Parameters:

width - the width

height - the height
