org.apache.sis.coverage.grid.ImageRenderer.Untiled

All Implemented Interfaces:

RenderedImage, WritableRenderedImage, Transparency

Enclosing class:

ImageRenderer

private static final class ImageRenderer.Untiled
extends BufferedImage

A BufferedImage which will compute the "org.apache.sis.GridGeometry" property when first needed. We use this class even when the property value is known in advance because it has the desired side-effect of not letting BufferedImage.getSubimage(int, int, int, int) inherit that property. The use of a BufferedImage subclass is desired because Java2D rendering pipeline has optimizations in the form if (image instanceof BufferedImage).

Field Details

geometry

private GridGeometry geometry

The value associated to the "org.apache.sis.GridGeometry" key, or null if not yet computed.

supplier

private SliceGeometry supplier

The object to use for computing geometry, or null if not needed. This field is cleared after geometry has been computed.

Constructor Details

Untiled

Untiled(ColorModel colors,
 WritableRaster raster,
 Hashtable<?,?> properties,
 GridGeometry geometry,
 SliceGeometry supplier)

Creates a new buffered image wrapping the given raster.

Method Details

getPropertyNames

public String[] getPropertyNames()

Returns the names of properties that this image can provide.

Specified by:

getPropertyNames in interface RenderedImage

Overrides:

getPropertyNames in class BufferedImage

getProperty

public Object getProperty(String key)

Returns the property associated to the given key. If the key is "org.apache.sis.GridGeometry", then the GridGeometry will be computed when first needed.

Specified by:

getProperty in interface RenderedImage

Overrides:

getProperty in class BufferedImage

Throws:

ImagingOpException - if the property value cannot be computed.
