A transform that applies noise to Type 2 (axial) shading patterns, which can reduce the appearance of banding on real print devices. The affected shading patterns are converted to images and (optionally) compressed.

|
| virtual void | setNoiseMagnitude (uint8 magnitude)=0 |
| | Set the magnitude of the noise to add, in bits. The default is 2.
|
| virtual void | setResolution (double xRes, double yRes=0.0)=0 |
| | Set the resolution(s) to use when converting affected shading patterns to images. The default is 300 for both x and y.
|
| virtual void | setCompress (bool compress)=0 |
| | Set whether or not the output should be compressed (flate). This can improve performance significantly if the result is to be written to PDF. The default is true.

| virtual | ~ITransform () |
| virtual IDOMBrushPtr | transform (const IDOMBrushPtr &brush, eBrushUsage usage=eBUGeneral, const CTransformState &state=CTransformState())=0 |
| | Apply the transform to the given brush, if applicable. These transforms are thread safe.
|
| virtual IDOMImagePtr | transform (const IDOMImagePtr &image, const CTransformState &state=CTransformState())=0 |
| | Apply the transform to the given image, if applicable. These transforms are thread safe.
|
| virtual IDOMColorPtr | transform (const IDOMColorPtr &color, const CTransformState &state=CTransformState())=0 |
| | Apply the transform to the given color, if applicable. These transforms are thread safe.
|
| virtual IDOMColorSpacePtr | transform (const IDOMColorSpacePtr &colorSpace, const CTransformState &state=CTransformState())=0 |
| | Apply the transform to the given color space, if applicable. These transforms are thread safe.
|
| virtual IDOMNodePtr | transform (const IDOMNodePtr &node, bool &changed, bool transformChildren=true, const CTransformState &state=CTransformState())=0 |
| | Apply the transform to the given node, if applicable. These transforms are thread safe, providing no other transforms are being applied to the same nodes at the same time.
|
| virtual void | transformPage (const IPagePtr &page, bool transformContent=true, bool transformAnnotations=true)=0 |
| | Apply the transform to the given page, if applicable. These transforms are thread safe, providing no other transforms are being applied to the same nodes at the same time. The transform will also apply to the annotations appearances.
|
| virtual void | flushCaches ()=0 |
| | Flush the caches used by the transform. Most transforms cache recently transformed results to improve the performance of repeated transformations of equivalent results. However, it is possible that some cached results may point to entities that no longer exist, such as content inside an XPS file that no longer exists. If you are deleting or replacing files where transforms have been used, it is advisable to invoke this routine to clear the caches.
|
| virtual void | setProgressMonitor (const IProgressMonitorPtr &progressMonitor)=0 |
| | Set the IProgressMonitor object for this transform to allow for monitoring the progress of the transform.
|
| virtual void | addRef () const =0 |
| | Increases the reference count of the actual object pointed to. This would take place during an assignment or copying.
|
| virtual bool | decRef () const =0 |
| | Decreases the reference count of the actual object pointed to. When the reference count falls to Zero, it deletes the actual object pointed to.
|
| virtual int32 | getRefCount () const =0 |
| | Retrieve the current reference count of the actual object pointed to.

A transform that applies noise to Type 2 (axial) shading patterns, which can reduce the appearance of banding on real print devices. The affected shading patterns are converted to images and (optionally) compressed.
Please note that if transform(IDOMBrush) is used, the transform will not apply denoising unless the input state provides clip bounds (state.hasClipBounds == true).
