getBounds2D
Description copied from interface:Filter
Returns the bounds of the current image. This should be 'in sync' with getMinX, getMinY, getWidth, getHeight- Specified by:
getBounds2D
in interfaceFilter
- Overrides:
getBounds2D
in classAbstractRable
-
setPadRect
Set the current rectangle for padding.- Specified by:
setPadRect
in interfacePadRable
- Parameters:
rect
- the new rectangle to use for pad.
-
getPadRect
Get the current rectangle for padding- Specified by:
getPadRect
in interfacePadRable
- Returns:
- Rectangle currently in use for pad.
-
setPadMode
Set the current extension mode for pad- Specified by:
setPadMode
in interfacePadRable
- Parameters:
padMode
- the new pad mode
-
getPadMode
Get the current extension mode for pad- Specified by:
getPadMode
in interfacePadRable
- Returns:
- Mode currently in use for pad
-
paintRable
Should perform the equivilent action as createRendering followed by drawing the RenderedImage to Graphics2D, or return false.- Specified by:
paintRable
in interfacePaintRable
- Parameters:
g2d
- The Graphics2D to draw to.- Returns:
- true if the paint call succeeded, false if for some reason the paint failed (in which case a createRendering should be used).
-
createRendering
- Specified by:
createRendering
in interfaceRenderableImage
-
getDependencyRegion
Description copied from interface:Filter
Returns the region of input data is is required to generate outputRgn.- Specified by:
getDependencyRegion
in interfaceFilter
- Overrides:
getDependencyRegion
in classAbstractRable
- Parameters:
srcIndex
- The source to do the dependency calculation for.outputRgn
- The region of output you are interested in generating dependencies for. The is given in the user coordiate system for this node.- Returns:
- The region of input required. This is in the user coordinate system for the source indicated by srcIndex.
-
getDirtyRegion
Description copied from interface:Filter
This calculates the region of output that is affected by a change in a region of input.- Specified by:
getDirtyRegion
in interfaceFilter
- Overrides:
getDirtyRegion
in classAbstractRable
- Parameters:
srcIndex
- The input that inputRgn reflects changes in.inputRgn
- the region of input that has changed, used to calculate the returned shape. This is given in the user coordinate system of the source indicated by srcIndex.- Returns:
- The region of output that would be invalid given a change to inputRgn of the source selected by srcIndex. this is in the user coordinate system of this node.
