Vuzit Document Viewer Blog

New Vuzit JavaScript API

We just released a new version of Vuzit. This release includes the Vuzit JavaScript API, which includes two objects: Viewer and Document. They will give you a lot of control over your documents. Read on.

Viewer Object

The Viewer object controls the document viewer. Use it to change pages, zoom levels, and more. Here is a list of some capabilities:

• Page through the document: nextPage, previousPage, and setPage
• Get the current page number: getPageNumber
• Resize the viewer: setSize
• Set and get the zoom level: setZoom and getZoom
• Set and get the URL of the document: setUrl and getUrl
• Event trigger when the viewer is done loading: onComplete (via setUrl)
• Get the document properties: getDocument (see Document object below)

Viewer usage: See this example.

Document Object

The Document object allows you to load various properties of the document like the number of pages, title, URL, and more. Here is a list of some capabilities:

• Number of pages: getPageCount
• Number of zoom levels: getZoomCount
• Size of the original document: getFileSize
• Title: getTitle
• Subject: getSubject
• URL: getUrl
• Width and height in pixels: getWidth and getHeight
• Last time the document was modified: getModifiedAt

Document usage: See this example.

We built the documentation using Natural Docs, the best document generator for JavaScript (in our opinion). It’s free and open source.
