classes.

| Constructor Summary | |
| public | MlibScaleOpImage(RenderedImage source, BorderExtender extender, Map config, ImageLayout layout, float scaleX, float scaleY, float transX, float transY, Interpolation interp, boolean cobbleSources)
Constructs a MlibScaleOpImage from a RenderedImage source,
Interpolation object, x and y scale values. |
| Method Summary | |
| protected Rectangle | backwardMapRect(Rectangle destRect, int sourceIndex)
Returns the minimum bounding box of the region of the specified
source to which a particular Rectangle of the
destination will be mapped.
Parameters:
destRect - the Rectangle in destination coordinates.
Parameters:
sourceIndex - the index of the source image. |
| MlibScaleOpImage | | public MlibScaleOpImage(RenderedImage source, BorderExtender extender, Map config, ImageLayout layout, float scaleX, float scaleY, float transX, float transY, Interpolation interp, boolean cobbleSources)(Code) | | Constructs a MlibScaleOpImage from a RenderedImage source,
Interpolation object, x and y scale values. The image
dimensions are determined by forward-mapping the source bounds.
The tile grid layout, SampleModel, and ColorModel are specified
by the image source, possibly overridden by values from the
ImageLayout parameter.
Parameters:
source - a RenderedImage.
Parameters:
extender - a BorderExtender, or null.or null. If null, a default cache will be used.
Parameters:
layout - an ImageLayout optionally containing the tile grid layout,SampleModel, and ColorModel, or null.
Parameters:
scaleX - scale factor along x axis.
Parameters:
scaleY - scale factor along y axis.
Parameters:
transX - translation factor along x axis.
Parameters:
transY - translation factor along y axis.
Parameters:
interp - an Interpolation object to use for resampling.
Parameters:
cobbleSources - a boolean indicating whether computeRect()expects contiguous sources. |
| backwardMapRect | | protected Rectangle backwardMapRect(Rectangle destRect, int sourceIndex)(Code) | | Returns the minimum bounding box of the region of the specified
source to which a particular Rectangle of the
destination will be mapped.
Parameters:
destRect - the Rectangle in destination coordinates.
Parameters:
sourceIndex - the index of the source image. a Rectangle indicating the source bounding box,or null if the bounding box is unknown.
throws:
IllegalArgumentException - if sourceIndex isnegative or greater than the index of the last source.
throws:
IllegalArgumentException - if destRect isnull. |
