Most image viewing applications and controls are designed for viewing a single image at a time. However some images and documents, such as TIFF and PDF, have multiple pages. Since these documents are typically full of text, it is very natural to keep reading on to the next page without the need to press a button to load the next page. We have received several requests for this feature and one of our developer support agents has created an demo showing how to implement continuous multipage scrolling with our HTML5 viewer and RESTful Web Services.

The basic idea works similarly to an image slider or carousel you might see on a homepage. There is an outer container which, when scrolled to a specified location, will asynchronously create an additional HTML5 Viewer for the next page and allow you to keep scrolling until you have reached the end of the document. Below is the JavaScript snippet which modifies the DOM with jQuery and calls the LEADTOOLS Raster Web service to retrieve the image.

We have received several requests regarding PACS and DICOM Communication within our Android imaging SDK. One way of accomplishing this is by using JSON to communicate with the RESTful web services included with the HTML5 Zero Footprint DICOM Viewer.

The snippet below shows a portion of the asynchronous code that calls the RESTful Medical Viewer Service and then parses the JSON response to get the SOP Instance UID. After that, the SOP Instance UID is used to get the image data and put it into an InputStream.

HIMSS 2013 is coming up in a few weeks and LEAD Technologies has some exciting plans for its exhibit this year. Stop by booth #2218 between March 4-6 to converse with our sales and technical support representatives about the recently released LEADTOOLS Version 18 and LEADTOOLS Anywhere™. In addition to our regular product information exhibits, we will be hosting four live Technology Showcase Presentations each day covering the following topics:

• Recognition Technologies
• PDF and Document Technologies
• DICOM Client Technologies
• PACS Server Framework with Zero Footprint HTML5 Medical Viewer

For more details on the times and covered topics for each presentation, please click here. You will also find a form to pre-register and let us know you're coming. Pre-registering is not required, but gives you an opportunity to ensure a meeting time and for us to answer any of your questions.
