Constructor Details

ImageGeometry

public ImageGeometry(GridGeometry grid,
 int[] dimensions)

Creates a deferred property for an image grid geometry.

Parameters:

grid - the grid geometry of the grid coverage rendered as an image.

dimensions - the dimensions to keep from the coverage grid geometry.

Method Details

apply

public GridGeometry apply(RenderedImage image)

Invoked when the PlanarImage.GRID_GEOMETRY_KEY value needs to be computed. The image should have been rendered from a grid coverage having the grid geometry given at construction time.

Specified by:

apply in interface Function<RenderedImage,GridGeometry>

Parameters:

image - the image for which to compute the property.

Returns:

the grid geometry property computed for the given image.
