Version 7.0.0 Changelog (2020-07-23)

See v7 migration guide for information on the breaking changes.

• A new and improved default UI that is structured a bit differently. The previous UI is still accessible with the constructor option ui: 'legacy'.
• All APIs now take 1-indexed page numbers. Previously some APIs would take 0-indexed page numbers.
• Search constants have been moved to the CoreControls namespace.
• PartRetriever classes can no longer be access directly, they should be used through the getPartRetriever API
• A few rarely used CanvasManager APIs have been removed: Core.CanvasMode, Core.setCanvasMode, DocumentViewer.setPagesPerCanvas, DocumentViewer.returnCanvas

• Added support for threaded WebAssembly. This means performance improvements by being able to render and process document pages and actions in parallel.
• Added a text comparison sample which shows how you can compare changes in the text of two different documents.
• Updated the RubberStampCreateTool to allow the creation of custom stamps.
• Updated the RubberStampCreateTool to allow setting a list of default stamps and custom stamps. These lists are used by default in the UI.
• Added a count measurement tool which will track the number of count annotations on the document.
• Properties and constants now consistently use the same casing throughout the WebViewer APIs. For example Namespace.MY_CONSTANT. The previous casings still remain for backwards compatibility.
• Added APIs to allow a custom appearance to be set on annotations when the PDF is downloaded
• Part retrievers are now split out from CoreControls.js and lazy loaded when needed.
• Added support for displaying polyline line endings
• Added annotation.isPrintVisible to check if annotation is visible when printing
• Added AnnotationManager.getCopiedAnnotations API to get the list of annotations that are currently copied
• Added a historyChanged event to AnnotationHistoryManager as well as the canUndo and canRedo functions.
• Added a getContents API to the FreeText editor instance
• Added a multiplier option to doc.loadCanvasAsync which changes the scaling factor for that particular loadCanvasAsync call
• Added a fitText API to FreeText and Callout annotations to programmatically fit the annotation to the text so that all text is visible
• Added a new event that is fired when the active search result has changed
• Added the useDisplayAuthor option to exportAnnotations so that the XFDF string will contain the mapped user display names.
• Added an optimized version of PDFNet.js that is significantly smaller than the default script by removing function type checks and warnings. It can be used by running the optimize script .
• Allow PDFDoc objects to be passed at the same time as the pdftronServer option and have them automatically uploaded to the server
• Updated so that if the option streaming: false is explicitly passed then there will be no check for whether the server support byte ranges or not
