I found a solution. I had a multipage document, but it was stored as single pages. So I created a directory for displaying them all with the WebThumbnailViewer. Now I changed my code that I first create one single multipage TIFF from all the single TIFF pages. With this change it works.

That works great for me. But when I just change:  <input type=''button'' value=''Rotate 90'' onclick=''Rotate(90);''> to: <input type=''image'' src=''./DynamicData/Content/Images/TurnRight.ico'' value=''Rotate 90'' onclick=''Rotate(90);'' /> It doesn't Why is that?

Recently, I posted an article describing a simple way to keep a session alive during long periods of inactivity. That works great if your web application doesn't rely on some other information on the server to maintain state. If you use DotImage in your web app, it maintains certain state information in the AtalaCache that needs to be updated ...

I have a webImageViewer control in an ASPX page (which also has UpdatePanel and UpdateProgress controls). I have the CacheLifeTime setting in the web.config file setup like this: <add key=''AtalasoftWebControls_CacheLifeTime'' value=''20''/> 20 minutes is the same as the site timeout in IIS.

This opens the TIF image in a new IE window and prints. Unfortunately, the quality is not as good as if I printed from some other image application. These images are detailed engineering ...

When developing two of my applications for 31 Apps in 31 Days (here and here), I discovered an issue with using YUI with our WebImageViewer. The script tag that references the YUI js files must be inside the main form element. If it is not, the DOM of the WebImageViewer gets distroyed and multiple painful errors ...

The WebImageViewer is a very powerful web control that we offer to our customers. It does a lot of work for you behind the scenes to make the experience as application-like as possible. It even takes that a step further with the RemoteInvoke method and RemoteInvoked event by providing customers with the ability to make server-side function calls ...

Last week, I posted 2 web apps (here and here) as part of our 31 Apps in 31 Days promotion. They both have one thing in common (outside of the fact that they're online): being full screen WebImageViewers. There are a few hoops that you need to hop through to make it happen, and this article will walk you through it. 1. Create a new Web Site ...

The main problem with percentage based height, especially in IE, is that every single parent element all the way up to the root html node must have a defined height in order for this to work.  This includes the html, body, form, and any master page placeholder tags between the form and the object you want to size with ...
