| BorderOpImage | | final class BorderOpImage extends OpImage (Code) | | An OpImage implementing the "border" operation.
It adds a border around a source image. The size of the border
is specified by the left, right, top, and bottom padding parameters.
The border may be filled in a variety of ways specified by the
border type parameter, defined in
javax.media.jai.operator.BorderDescriptor:
- it may be extended with zeros (BORDER_ZERO_FILL);
- it may be extended with a constant set of values (BORDER_CONST_FILL);
it may be created by reflection about the edges of the image
(BORDER_REFLECT); or,
- it may be extended by "wrapping" the image plane toroidally,
that is, joining opposite edges of the image.
When choosing the BORDER_CONST_FILL option, an array
of constants must be supplied. The array must have at least one element,
in which case this same constant is applied to all image bands. Or,
it may have a different constant entry for each cooresponding band.
For all other border types, this constants parameter may
be null.
The layout information for this image may be specified via the
layout parameter. However, due to the nature of this
operation, the minX, minY, width,
and height, if specified, will be ignored. They will
be calculated based on the source's dimensions and the padding values.
Likewise, the SampleModel and ColorModel hints
will be ignored.

Returns a conservative estimate of the region of a specified
source that is required in order to compute the pixels of a
given destination rectangle.
Parameters:
destRect - the Rectangle in destination coordinates.
Parameters:
sourceIndex - the index of the source image. | | public Rectangle | mapSourceRect(Rectangle sourceRect, int sourceIndex)
Returns a conservative estimate of the destination region that
can potentially be affected by the pixels of a rectangle of a
given source.
Parameters:
sourceRect - the Rectangle in source coordinates.
Parameters:
sourceIndex - the index of the source image. |
| extender | | protected BorderExtender extender(Code) | | The BorderExtender object used to extend the source data.

Parameters:
source - The source image.
Parameters:
layout - The destination image layout.
Parameters:
leftPad - The amount of padding to the left of the source.
Parameters:
rightPad - The amount of padding to the right of the source.
Parameters:
topPad - The amount of padding to the top of the source.
Parameters:
bottomPad - The amount of padding to the bottom of the source.
Parameters:
type - The border type.
Parameters:
constants - The constants used with border typeBorderDescriptor.BORDER_CONST_FILL,stored as reference. |
| computeTile | | public Raster computeTile(int tileX, int tileY)(Code) | | Computes the pixel values for the specified tile.
|
| mapDestRect | | public Rectangle mapDestRect(Rectangle destRect, int sourceIndex)(Code) | | Returns a conservative estimate of the region of a specified
source that is required in order to compute the pixels of a
given destination rectangle.
Parameters:
destRect - the Rectangle in destination coordinates.
Parameters:
sourceIndex - the index of the source image. a Rectangle indicating the required source region.
throws:
IllegalArgumentException - if the source index isnegative or greater than that of the last source.
throws:
IllegalArgumentException - if destRect is null. |
| mapSourceRect | | public Rectangle mapSourceRect(Rectangle sourceRect, int sourceIndex)(Code) | | Returns a conservative estimate of the destination region that
can potentially be affected by the pixels of a rectangle of a
given source.
Parameters:
sourceRect - the Rectangle in source coordinates.
Parameters:
sourceIndex - the index of the source image. a Rectangle indicating the potentially affecteddestination region. or null if the region is unknown.
throws:
IllegalArgumentException - if the source index isnegative or greater than that of the last source.
throws:
IllegalArgumentException - if sourceRect is null. |
