virtual void | setShouldSubset (bool subset)=0 |
| | Set whether or not subsetting should be performed. The default is true.
|

|
virtual void | setShouldMerge (bool merge)=0 |
| | Set whether or not font merging should be performed. The default is true.
|
| |
|
virtual void | setIgnoreUnembeddedFonts (bool ignore)=0 |
| | Set whether or not fonts that are not marked for embedding should be ignored by this transform. The default is false.
|

|
virtual void | setIgnoreRestrictedFonts (bool ignore)=0 |
| | Set whether or not fonts that are marked as restricted should be ignored by this transform. The default is false.
|
| |
|
virtual void | setIgnoreFonts (const CU8StringVect &ignoreFonts)=0 |
| | Specify a list of font names that should not be processed by this transform. A font will be ignored if its PostScript name matches any string in this vector. The default is an empty vector.
|
| |
| virtual bool | shouldMerge ()=0 |
| | Determine if font merging has been enabled.
|
| |
| virtual bool | shouldSubset ()=0 |
| | Determine if font subsetting has been enabled.

| 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 colorspace, 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 for performing font subsetting and merging.
When merging fonts, this transform will see if fonts inside the object
being transformed can be merged with fonts that the transform has
previously seen. If so, the font will be merged. If a previously seen
font provides all the required glyphs, that previous font will be used.
However, if no previous font provides all the required glyphs, a new
font will be created.
When subsetting fonts, the transform will attempt to use previously
seen subset fonts that support the required glyphs. If not, a new subset
font will be created.
However both these operations should be performed over as large a set
of input as possible as these operations lose their effectiveness when
operating on, for example, single pages.
For example, if in a five page job, five potentially mergable fonts are
used, one per page. If each font adds glyphs that were not present, then
this transform will do a poor job. When run for each page we will be able
to merge each font, but will then need to generate a new font each time
due to the additional glyphs, resulting in essentially the same result
as the input.
For such situations, consider using the IFontProcessorDeferredTransform
transform, which would allow merging to be performed over a set of pages.
For the example above, it would be able to generate a single font as it
is able to defer creation of a merged font until after it has identified
the fonts that can be merged.
