Examples of BorderExtenderConstant

com.lightcrafts.mediax.jai.BorderExtenderConstant
A subclass of BorderExtender that implements border extension by filling all pixels outside of the image bounds with constant values. For example, the image:

A B C

D E F

G H I

if extended by adding two extra rows to the top and bottom and two extra columns on the left and right sides, would become:

X X X X X X X

X X X X X X X

X X A B C X X

X X D E F X X

X X G H I X X

X X X X X X X

X X X X X X X

where X is the constant fill value. The set of constants is clamped to the range and precision of the data type of the WritableRaster being filled. The number of constants used is given by the number of bands of the WritableRaster. If the WritableRaster has b bands, and there are c constants, constants 0 through b - 1 are used when b <= c. If there is only a single constant, then it is used for all bands. If b > c, an UnsupportedOperationException is thrown. @see BorderExtender

        // We have yet to check for it usefulness: it might be more convenient
        // to check for region overlapping and return a nodata value by hand,
        // so to avoid problems with interpolation at source raster borders.
        //
        BorderExtender extender = new BorderExtenderConstant(new double[] { nodata });
        
        // add tile caching to the mix
