LEADVIEW Viewer Application

• The LEADTOOLS JS files
  • Leadtools.js
  • Leadtools.Controls.js
  • Leadtools.Annotations.Engine.js
  • Leadtools.Annotations.Designers.js
  • Leadtools.Annotations.Rendering.Javascript.js
  • Leadtools.Annotations.Automation.js
  • Leadtools.Document.js
  • Leadtools.Document.Viewer.js
• JQuery must be referenced in order for the LEADTOOLS Document JS libraries to work.
• LEADVIEW needs some form of bootstrap CSS included (in order to display dialogs appropriately).
• In order to load PDF files locally, the lt.pdf.js (at <INSTALLDIR>\Bin\JS\pdfjs\) files must be set up accordingly. The LEADVIEW demo shows how to do this.
• LEADVIEW looks in <INSTALLDIR>\Examples\JS\DocumentViewerDemos\LEADVIEW_DocumentViewerDemo\wwwroot\Resources\Cursors for annotation cursors. Place any custom cursors there. The LEADVIEW demo also shows how to do this.

Setting up LEADVIEW

The LEADVIEW Viewer library is split into two files: Leadtools.LEADVIEW.js (at <INSTALLDIR>\Bin\JS\) and Leadtools.LEADVIEW.css (at <INSTALLDIR>\Examples\JS\DocumentViewerDemos\LEADVIEW_DocumentViewerDemo\wwwroot\Styles).

At runtime, LEADVIEW will look for a LEADVIEW.json file in the <INSTALLDIR>\Examples\JS\DocumentViewerDemos\LEADVIEW_DocumentViewerDemo\wwwroot\LEADVIEW folder from the web application's root. Set the startupSettings property in the LEADVIEW.json file, which tells LEADVIEW where to look for the appropriate settings file. If no valid path is provided, or if LEADVIEW fails to pull the settings, the default settings will be used.

The JSON Settings files can be generated directly from LEADVIEW. Examples of these settings files can be found in the wwwroot\LEADVIEW directory for the example at <INSTALLDIR>\Examples\JS\DocumentViewerDemos\LEADVIEW_DocumentViewerDemo.

Starting LEADVIEW

At this point, all you need to do to start using LEADVIEW is to run the following 2 lines of code:

let lv = new lt.LEADVIEW.Viewer(); 
lv.run(null,null);
