| AbsoluteOpImage | | final class AbsoluteOpImage extends PointOpImage (Code) | | An OpImage implementing the "Absolute" operation as
described in javax.media.jai.operator.AbsoluteDescriptor.
This OpImage takes the absolute value of the pixel
values of an image. The operation is done on a per-band basis.
For an integral number, its absolute value is taken as x = (~x) +1,
where ~x is the 1's complement of that number.
If the number is the maximum negative of its type, then it will remain
the same value.

| Constructor Summary | |
| public | AbsoluteOpImage(RenderedImage source, Map config, ImageLayout layout)
Constructs an AbsoluteOpImage.
The layout parameter may optionally contains the
tile grid layout, sample model, and/or color model. |
| Method Summary | |
| protected void | computeRect(Raster[] sources, WritableRaster dest, Rectangle destRect)
Map the pixels inside a specified rectangle whose value is within a
rang to a constant on a per-band basis. |
| AbsoluteOpImage | | public AbsoluteOpImage(RenderedImage source, Map config, ImageLayout layout)(Code) | | Constructs an AbsoluteOpImage.
The layout parameter may optionally contains the
tile grid layout, sample model, and/or color model. The image
dimension is set to the same values as that of the source image.
The image layout of the source image is used as the fall-back
for the image layout of the destination image. 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
rang 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. |
