Class FilterChainRable8Bit  

java.lang.Object
  org.apache.batik.ext.awt.image.renderable.AbstractRable

All Implemented Interfaces:

Filter, FilterChainRable, PaintRable, java.awt.image.renderable.RenderableImage

public class FilterChainRable8Bit

extends AbstractRable

implements FilterChainRable, PaintRable

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:

• 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

Field Detail

filterResolutionX

private int filterResolutionX

Resolution along the X axis

---

filterResolutionY

private int filterResolutionY

Resolution along the Y axis

---

chainSource

private Filter chainSource

The chain's source

---

filterRes

private FilterResRable filterRes

Scale operation. May be null

---

crop

private PadRable crop

Crop operation.

---

filterRegion

private java.awt.geom.Rectangle2D filterRegion

Filter region

Constructor Detail

FilterChainRable8Bit

public FilterChainRable8Bit(Filter source,
                            java.awt.geom.Rectangle2D filterRegion)

Default constructor.

Method Detail

getFilterResolutionX

public int getFilterResolutionX()

Returns the resolution along the X axis.

Specified by:

getFilterResolutionX in interface FilterChainRable

---

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 interface FilterChainRable

---

getFilterResolutionY

public int getFilterResolutionY()

Returns the resolution along the Y axis.

Specified by:

getFilterResolutionY in interface FilterChainRable

---

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 interface FilterChainRable

---

setupFilterRes

private void setupFilterRes()

Implementation. Checks the current value of the filterResolutionX and filterResolutionY attribute and setup the filterRes operation accordingly.

---

setFilterRegion

public void setFilterRegion(java.awt.geom.Rectangle2D filterRegion)

Sets the filter output area, in user space. A null value is illegal.

Specified by:

setFilterRegion in interface FilterChainRable

---

getFilterRegion

public java.awt.geom.Rectangle2D getFilterRegion()

Returns the filter output area, in user space

Specified by:

getFilterRegion in interface FilterChainRable

---

getSource

public Filter 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 interface FilterChainRable

---

setSource

public void setSource(Filter chainSource)

Sets the source to be src.

Specified by:

setSource in interface FilterChainRable

---

getBounds2D

public java.awt.geom.Rectangle2D getBounds2D()

Returns this filter's bounds

Specified by:

getBounds2D in interface Filter

Overrides:

getBounds2D in class AbstractRable

---

paintRable

public boolean paintRable(java.awt.Graphics2D g2d)

Should perform the equivilent action as createRendering followed by drawing the RenderedImage to Graphics2D, or return false.

Specified by:

paintRable in interface PaintRable

---

createRendering

public java.awt.image.RenderedImage createRendering(java.awt.image.renderable.RenderContext context)

Specified by:

createRendering in interface java.awt.image.renderable.RenderableImage
