createImage

protected final RenderedImage createImage(int level)

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.

computeTopLeftMatrixCellReadBounds
