Apryse's WebViewer comes with semantic comparison available that enables comparing semantic differences between two PDF files. This feature is useful when you want to compare two versions of a document and highlight the differences between them. The comparison is done at the text level and highlights the differences in the text content between the two PDF files.
To enable semantic compare, you can set enableSemanticCompareMode
to true. This will enable the mode to perform a comparison.
You can then load two PDF files into the WebViewer to compare them. You can provide two URLs to the url
or Appian document IDs to the appianDocId
property for it to load. Without providing two URLs or document IDs, WebViewer will wait for users to provide two documents to compare.

appianDocId: { 1626, 1423 },

When two documents are loaded, the user can then press the Start Comparison
button in the header to start the comparison. The comparison will highlight the differences between the two documents.
To automatically compare when two documents are loaded, you can set automaticSemanticCompare
to true. This will automatically start the comparison when two documents are loaded.
When comparing two documents, you can enable sync scrolling by pressing the sync icon in the top right corner of either viewer. This will sync the scrolling of the two documents so that they scroll together.
