Big Faceless Java PDF library 2.11.7

Enhancements:

• Added AnnotationShape and associated editors in the Viewer, to create and manipulate lines, arrows, polylines, ellipses and rectangles using the java.awt.geom package.
  
• Improvements to the way AnnotationLink and AnnotationMarkup work on rotated pages. This now works when creating or moving annotations on all types of rotated pages. Improved set/getCorners and set/getRectangle interaction. Correctly position all forms of rotated annotation on all variations of rotated page in the Viewer and when rendering.
  
• Added ability to arbitrarily rotate AnnotationStamp objects.
  
• Added the AnnotationSound class, to manage sound annotations as created by Acrobat. Note this is the "Acrobat 5 and earlier" approach as described in Acrobat 9.
  
• Added PDFStyle.setBlendMode method, which can be used to modify the blend mode of PDF content or some annotations that use blend modes (shapes & text).
  
• Added PDFCanvas.drawShape(java.awt.geom.Shape), related clip/path methods and PDFCanvas.transform(java.awt.geom.AffineTransform).
  
• Fixed non-JavaScript date formatting when the date format contains commas.
  
• Fixed, again, a small memory leak first fixed in 2.3.5 that reappeared.
  
• Catch particular type of corruption when loading PDF Tokens from stream.
  
• Add optimization for daft approach occasionally used by GhostScript when rendering lines.
  
• Added PageExtractor.Text.getBaseline
  
• Improvements to text extraction algorithm should result in less words being run together, and to prevent any concurrency issues if extraction is started from multiple threads simultaneously.
  
• Text extractor no longer joins together adjacent words with different colors. What is "different" can be set by the "org.faceless.pdf2.TextColorDistance" System property, which may vary from 0 to about 170 (which would treat all colors as identical, the behaviour prior to 2.11.6). Fix case where imagemask size != image size and image is not RGB.
  
• Prevent out-of-gamut results caused by unwanted switch to RGB when rendering CMYK PDFs containing complex blends.
  
• Added workaround for unidentified bug in AWT with non-standard Composites.
  
• Added support for the JBIG decoding using the BSD-licensed JBIG2 decoder, and improvements to the garbage collection of temporary files when using the "jbig2dec" native JBIG2 decoder.
  
• PDFs containing annotations without matching fields are repaired by adding those fields rather than remove the annotations, matching Acrobat's behaviour.
  
• Added support for javax.sound.sampled.AudioInputStream to PDFSound objects.
  
• Fixes to the WidgetAnnotation.get/setAction method to correctly handle the two ways Acrobat may do this.
  
• Numerous improvements to FDF and XFDF exporting - exporting of annotations now properly supported.
  
• Fixed linearization where bookmarks should be displayed but are missing.
  
• Improvements to text sizing algorithm for auto-sized text in text fields.
  
• Viewer: Made consistant the approach to initializing viewer features via the "initialization parameter" concept. Many features can now be configured at runtime - for instance Thumbnails can be made read-only, initial view of the viewer can be set and more.
  
• Viewer: Text selection has been rewritten and is vastly improved. Selection now works across the entire document, which means a selection is not garbage collected if a page has been scrolled away. Text can be selected by mouse as before, or now also programmatically via a regular expression.
  
• Viewer: Actions may be performed on selected text via the TextSelectionAction class, by right-clicking on selected text. Actions are supplied to create markup annotations of various types.
  
• Viewer: Signatures can be verified when a PDF is loaded or programatically, with the new BackgroundSignatureVerifier feature.
  
• Viewer: Text extraction of a PDF may be started in the background via the new BackgroundTextExtractor feature.
  
• Viewer: long running tasks like thumbnail painting are now paused while the PDF is being saved, to avoid concurrency issues.
  
• Viewer: Lines and Arrow annotations can be drawn intuitively onto the PDF via the new AnnotatonAddLine feature.
  
• Viewer: Fixed deadlock when JavaScript was updating a field that had just been edited.
  
• Viewer: Side panels (thumbnails, signatures, search results) are optinally displayed as icons now thanks to the new SidePanel.getIcon method.
  
• Viewer: Thumbnail panel now scrolls to follow the current page, as Acrobat. This can be controlled programatically.
  
• Viewer: All appropriate annotations can be deleted as well as edited by right clicking on them. Editing annotations requires a double click, not a single.
  
• Viewer: Further corrections to fix component focus, started in 2.11.6
  
• Viewer: Sounds embedded in the PDF are now played.
  
• Viewer: Add default-disabled Features, see ViewerFeature.isEnabledByDefault().
  
• Viewer: Timeout for form submissions can be controlled.
