 com.sun.media.jai.opimage.ExpOpImage
| ExpOpImage | | final class ExpOpImage extends ColormapOpImage (Code) | | An OpImage implementing the "Exp" operation as
described in javax.media.jai.operator.ExpDescriptor.
The result is rounded to the closest integer for intergral data types.
This OpImage takes the natural exponential of the pixel
values of an image. The operation is done on a per-pixel, per-band
basis.

| Constructor Summary | |
| public | ExpOpImage(RenderedImage source, Map config, ImageLayout layout)
Constructor.
The layout of the source is used as the fall-back for
the layout of the destination. |
| Method Summary | |
| protected void | computeRect(Raster[] sources, WritableRaster dest, Rectangle destRect)
Map the pixels inside a specified rectangle whose value is within a
range to a constant on a per-band basis. | | protected void | transformColormap(byte[][] colormap)
Transform the colormap according to the rescaling parameters. |
| ExpOpImage | | public ExpOpImage(RenderedImage source, Map config, ImageLayout layout)(Code) | | Constructor.
The layout of the source is used as the fall-back for
the layout of the destination. Any layout parameters not
specified in the layout argument are set to
the same value as that of the source.
Parameters:
source - The source image.
Parameters:
layout - The destination image layout. |
| computeRect | | protected void computeRect(Raster[] sources, WritableRaster dest, Rectangle destRect)(Code) | | Map the pixels inside a specified rectangle whose value is within a
range to a constant on a per-band basis.
Parameters:
sources - Cobbled sources, guaranteed to provide all thesource data necessary for computing the rectangle.
Parameters:
dest - The tile containing the rectangle to be computed.
Parameters:
destRect - The rectangle within the tile to be computed. |
| transformColormap | | protected void transformColormap(byte[][] colormap)(Code) | | Transform the colormap according to the rescaling parameters.
