| AffineOpImage | | class AffineOpImage extends GeometricOpImage (Code) | | An OpImage class to perform (possibly filtered) affine mapping between
a source and destination image.
The geometric relationship between source and destination pixels
is defined as the following (x and y denote
the source pixel coordinates; x' and y'
denote the destination pixel coordinates; m denotes the
3x2 transform matrix):
x' = m[0][0] * x + m[0][1] * y + m[0][2]
y' = m[1][0] * x + m[1][1] * y + m[1][2]

| AffineOpImage | | public AffineOpImage(RenderedImage source, BorderExtender extender, Map config, ImageLayout layout, AffineTransform transform, Interpolation interp, double[] backgroundValues)(Code) | | Constructs an AffineOpImage from a RenderedImage source,
AffineTransform, and Interpolation object. 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.
Parameters:
layout - an ImageLayout optionally containing the tile grid layout,SampleModel, and ColorModel, or null.
Parameters:
transform - the desired AffineTransform.
Parameters:
interp - an Interpolation object. |
| backwardMapRect | | protected Rectangle backwardMapRect(Rectangle destRect, int sourceIndex)(Code) | | Backward map the destination Rectangle.
|
| ceilRatio | | protected static int ceilRatio(long num, long denom)(Code) | | Computes ceil(num/denom) using integer arithmetic.
denom must not be equal to 0.
|
| computeTile | | public Raster computeTile(int tileX, int tileY)(Code) | | |
| floorRatio | | protected static int floorRatio(long num, long denom)(Code) | | Computes floor(num/denom) using integer arithmetic.
denom must not be equal to 0.
|
| forwardMapRect | | protected Rectangle forwardMapRect(Rectangle sourceRect, int sourceIndex)(Code) | | Forward map the source Rectangle.
|
| mapDestPoint | | public Point2D mapDestPoint(Point2D destPt)(Code) | | Computes the source point corresponding to the supplied point.
Parameters:
destPt - the position in destination image coordinatesto map to source image coordinates. a Point2D of the same class asdestPt.
throws:

since:
JAI 1.1.2 |
| mapDestPoint | | public void mapDestPoint(Point2D destPoint, Point2D srcPoint)(Code) | | Backward map a destination coordinate (using inverse_transform)
to get the corresponding source coordinate.
We need not worry about interpolation here.
