Implements a filter chain. A filter chain is defined by its
filter region (i.e., the bounding box of its input/output), its
filter resolution and its source. Its source cannot be null,
but its resolution can.
The filter chain decomposes as follows:
The filter chain decomposes as follows:
- A pad operation that makes the input image a big as the filter region.
- If there is a filterResolution specified along at least
one of the axis, a
AffineRable

Method Details
-
getFilterResolutionX
public int getFilterResolutionX()Returns the resolution along the X axis.- Specified by:
getFilterResolutionX
in interfaceFilterChainRable
-
setFilterResolutionX
public void setFilterResolutionX(int filterResolutionX) Sets the resolution along the X axis, i.e., the maximum size for intermediate images along that axis. If filterResolutionX is less than zero, no filter resolution is forced on the filter chain. If filterResolutionX is zero, then the filter returns null. If filterResolutionX is positive, then the filter resolution is applied.- Specified by:
setFilterResolutionX
in interfaceFilterChainRable
-
getFilterResolutionY
public int getFilterResolutionY()Returns the resolution along the Y axis.- Specified by:
getFilterResolutionY
in interfaceFilterChainRable
-
setFilterResolutionY
public void setFilterResolutionY(int filterResolutionY) Sets the resolution along the Y axis, i.e., the maximum size for intermediate images along that axis. If filterResolutionY is zero or less, the value of filterResolutionX is used.- Specified by:
setFilterResolutionY
in interfaceFilterChainRable
-
setupFilterRes
private void setupFilterRes()Implementation. Checks the current value of the filterResolutionX and filterResolutionY attribute and setup the filterRes operation accordingly. -
setFilterRegion
Sets the filter output area, in user space. A null value is illegal.- Specified by:
setFilterRegion
in interfaceFilterChainRable
-
getFilterRegion
Returns the filter output area, in user space- Specified by:
getFilterRegion
in interfaceFilterChainRable
-
getSource
Returns the source of the chain. Note that a crop and affine operation may be inserted before the source, depending on the filterRegion and filterResolution parameters.- Specified by:
getSource
in interfaceFilterChainRable
-
setSource
Sets the source to be src.- Specified by:
setSource
in interfaceFilterChainRable
- Parameters:
chainSource
- image to the chain.
-
getBounds2D
Returns this filter's bounds- Specified by:
getBounds2D
in interfaceFilter
- Overrides:
getBounds2D
in classAbstractRable
-
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
