DotImage Zero Footprint AJAX-Enabled ASP.NET Imaging Controls

Atalasoft’s innovative AJAX-enabled imaging controls for ASP.NET with Tile On Demand^TM technology brings image and document processing on the web to a new level with the most universal, efficient, and powerful thin-client, server-side imaging controls available.  The overhead involved in deploying and maintaining a thick-client enterprise application can be very expensive.  Atalasoft's DotImage provides ASP.NET applications the ability to include AJAX-enabled web controls for viewing images, annotating images, viewing thumbnails, and editing images with 100% server-side processing and a dynamic AJAX browser UI for both 32-bit and 64-bit servers.  DotImage Document Imaging includes three AJAX enabled controls for Image Viewing and Editing, Thumbnail Viewing, authoring annotations, and viewing annotations. 

• Try our online AJAX Document and Annotations Editor, and AJAX Photo Viewer/Editor for some sample applications developed using these controls.
• See our Tutorial Videos to see how easy it is to make a webpage with AJAX-enabled thumbnails and image viewers with annotation support.

The DotImage WebForm controls are customizable, unlike other web based image viewing products. These controls can be dragged and dropped onto your own ASP.NET webpage and be completely customized with access to the full power of the DotImage Imaging Toolkit.

WebImageViewer

The AJAX enabled WebImageViewer is used to view and edit images in a browser.  This control works by loading tiled sections of an image "On-Demand" when the relevant section of an image is panned or zoomed into view, converting each tile to a browser friendly format on the fly.  It is especially optimized to view tiled and stripped TIFF's as it selectively decodes tiles from the source image as it streams them to the client.  Perfect for viewing large TIFF images, such as mechanical CAD drawings, or documents scanned at a high resolution as the bandwidth requirements for the client are minimal. Also perfect for a universal document and image viewer when combined with the other supported codecs such as PDF, JPEG2000, and the other built-in formats.

This control is also very useful for processing images interactively by tying a button to a server method, resulting in the image updating without a page postback  The rubberband selection feature can be used for cropping an image, or selecting an area of an image. 

WebThumbnailViewer

The AJAX enabled WebThumbnailViewer is used to view multiple thumbnails from images stored in a multi-page document such as a TIFF or PDF, or can be used to view thumbnail images from a folder.  This control works by loading thumbnails "On-Demand" reducing bandwidth requirements and enabling the control to view thousands of thumbnails that are loaded only when scrolling in view.  This control can be tied with the WebImageViewer for an advanced document image viewer.

WebAnnotationViewer

The AJAX enabled WebAnnotationViewer is used to annotate image annotations in a browser. Since it is based on the WebImageViewer, you get all of its features (panning, zooming, tiling, etc), plus the ability to create, delete, view, and modify annotations without a postback. It uses the same rendering and data engine as DotImage Annotations, so annotations can be created on the web and viewed in a WinForms app and vice-versa. This control is useful for marking up images on the web either in a collaborative environment or in an online image workflow application.

Document Viewer

The ASP.NET Web Controls included with DotImage Document Imaging can be used to create a server-side multi-page document imaging application for a universal image viewer to support TIFF and FAX documents, PDF's and any other format supported by Atalasoft.   DotTwain can be used to add a web deployed scanning component to your thin-client application.  Our online document image viewer and annotations viewer demonstrate these features.

The DotImage AJAX enabled web image viewer is currently in production use by a number of clients as an enterprise level document image viewer within their web imaging application. Read how Captaris integrated DotImage WebImageViewer into their RightFax software.
