Module org.apache.sis.feature

Package org.apache.sis.image

package org.apache.sis.image

Provides helper classes for handling Java2D rendered images together with some operations. This package does not provide any geospatial functionalities; it works only on sample or pixel values stored in Rendered­Images. Those rendered images have the following capabilities:

• Images may have an arbitrary number of bands (not necessarily RGB).
• Sample values can be bytes, shorts (signed or unsigned), integers or floating-point values.
• Images can be tiled.

This package is used as a basis for georectified or georeferenceable grid coverages.

Usage note

Some images are writable. But modifying pixel values should be done by invoking the get­Writable­Tile(…) and release­Writable­Tile(…) methods of Writable­Rendered­Image interface. Do not cast directly a Raster to Writable­Raster even when the cast is safe, because some raster data may be shared by many tiles having identical content. Furthermore, changes in pixel values may be lost if release­Writable­Tile(…) is not invoked.
