Test-drive Zoom for ASP.NET with the following Live Demos:


Zoom Shop
Zoom is used to display products as they would appear in an online storefront. This sample demonstrates how a single control can be re-used on an ASP.NET WebForm and generate image data on-demand.



Zoom Configurator
Interactively set many of the Zoom's properties at runtime. The sample demonstrates how the control can be configured or optimized for the particular image for the best quality and performance.



Points of Interest
Demonstrates how a developer can capture specific locations within an image to be recalled at a later date. This functionality is very useful for producing interactive tours or pointing out particular features of a photograph.

Benefit from your existing ASP.NET development expertise

A comprehensive server-side object model and client script API is provided with full ASP.NET rapid application development support.
PowerWEB Zoom allows ASP.NET developers to deliver complex interactivity without requiring any new skills. Because Zoom is an ASP.NET server control, it can be configured and integrated into applications using any valid .NET language, including C# and VB.NET. Zoom’s server-side object model offers programmatic manipulation of:


  • Control style and visibility
  • Physical dimensions
  • Source image swapping
  • Image pan and zoom location for dynamic walkthroughs
  • Server events


Additionally, Zoom provides a client script API which includes functions for:


  • Integration with other Ajax controls and libraries
  • Automation of pan and zoom activities

Add in-line interactivity to your websites' images

Now users can selectively interact with hi-res images alongside related content instead of toggling between separate pages and pop-ups.

Problem: Bandwidth and layout dictate that image files must be small enough to download quickly and sized so as not to interfere with a site’s visual design.
Using pop-up windows to display higher resolution images or providing links to larger images force users to deal with obtrusive browser windows or awkward navigation.

Using pop-ups and external links can be distracting and disruptive to the user experience.



Solution: Combining images with effective text is a powerful way of capturing and maintaining end-user attention.
E-commerce relies heavily on clear product representation. Document management systems require legible photos of source material. Online publishing is greatly enhanced by striking visuals.

Placing Zoom within a content page allows users to navigate through image details while keeping supporting materials front and center.

  • Microsoft Internet Explorer (6.x+)
  • Firefox (1.5.x)

Use full resolution, high quality images

Configurable dynamic rendering allows you to use high quality original images...no need to create thumbnails or prepare low resolution duplicates.
Web development with images has always been an exercise in compromise. Bandwidth, file space, performance requirements, and site design have forced developers to provide low or medium resolution images to end users.


With Zoom, there is no reason to deliver low-quality images or sacrifice end user experience. Because Zoom dynamically generates scaled and optimized versions of source files, you can focus on delivering a quality product to your end users instead of spending hours sizing images or manipulating compression levels. High-res source photos can be used directly with Zoom!

Display high resolution images quickly and efficiently

On-demand delivery of image sections provides immediate viewing without lengthy downloads.


Downloading and displaying a large, high resolution image on the web is an inefficient process. When the image is requested, the server streams the entire file down to the browser. During this slow and bandwidth intensive process, the image will begin to render. Depending on the type of image being transferred, the rendering is manifested by either a top-down filling of the physical window (GIF, TIFF, JPEG), or a gradual sharpening of a rough, pixelated version (interlaced GIF, progressive JPEG). In either case, the end-user must wait several seconds before seeing a usable image. This is a time-consuming process which can quickly frustrate end-users.


Eliminate lengthy downloads for high-resolution images.



A more efficient and usable approach is to deliver only the visible portion of an image to the client. By default, Zoom displays a reduced version of the source image. When a user zooms into an image detail, the server delivers only the portion that will be visible at that location.
As the user pans across the image, more details are streamed on-demand without reloading the page or interrupting the user experience.
