- com.bc.ceres.glevel.support.AbstractMultiLevelSource
- - com.bc.ceres.glevel.support.GenericMultiLevelSource

All Implemented Interfaces:

MultiLevelSource
```
public abstract class GenericMultiLevelSource
extends AbstractMultiLevelSource
```
A GenericMultiLevelSource is a MultiLevelSource computing its images at a given resolution level from a number of source images of the same level.
Subclasses will have to to implement createImage(java.awt.image.RenderedImage[], int).

    Description copied from class: AbstractMultiLevelSource
    
    Called by AbstractMultiLevelSource.getImage(int) if a level image is requested for the first time. Note that images created via this method will be disposed when AbstractMultiLevelSource.reset() is called on this multi-level image source. See AbstractMultiLevelSource.getImage(int).
    The dimension of the level image created must be the same as that obtained from {DefaultMultiLevelSource.getLevelImageBounds(Rectangle sourceBounds, double scale)} for the scale associated with the given resolution level.
    
    Specified by:
    
    createImage in class AbstractMultiLevelSource
    
    Parameters:
    
    level - The resolution level.
    
    Returns:
    
    An instance of a RenderedImage for the given resolution level.
