 com.sun.media.jai.mlib.MlibFilteredSubsampleOpImage
| Method Summary | |
| public void | computeRect(Raster[] sources, WritableRaster dest, Rectangle destRect)
Performs a combined subsample/filter operation on a specified rectangle. |
| m_hKernel | | protected double[] m_hKernel(Code) | | |
| m_vKernel | | protected double[] m_vKernel(Code) | | |
| MlibFilteredSubsampleOpImage | | public MlibFilteredSubsampleOpImage(RenderedImage source, BorderExtender extender, Map config, ImageLayout layout, int scaleX, int scaleY, float[] qsFilter, Interpolation interp)(Code) | | MlibFilteredSubsampleOpImage constructs an OpImage representing
filtered integral subsampling. The scale factors represent the ratio of
source to destination dimensions.
Parameters:
source - a RenderedImage.
Parameters:
extender - a BorderExtender, or null.
Parameters:
config - a Map object possibly holding tile cache information
Parameters:
layout - an ImageLayout optionally containing the tile grid layout,SampleModel, and ColorModel, or null.
Parameters:
interp - a Interpolation object to use for resampling.
Parameters:
scaleX - downsample factor along x axis.
Parameters:
scaleY - downsample factor along y axis.
Parameters:
qsFilter - symmetric filter coefficients (partial kernel).
throws:
IllegalArgumentException - if the interp type is not one of:INTERP_NEAREST, INTERP_BILINEAR, INTERP_BICUBIC, or INTERP_BICUBIC_2 |
| computeRect | | public void computeRect(Raster[] sources, WritableRaster dest, Rectangle destRect)(Code) | | Performs a combined subsample/filter operation on a specified rectangle.
The sources are cobbled.
Parameters:
sources - an array of source Rasters, guaranteed to provide allnecessary source data for computing the output.
Parameters:
dest - a WritableRaster containing the area to be computed.
Parameters:
destRect - the rectangle within dest to be processed. |
