Demonstrates applying DotImage Advanced Document Cleanup algorithms in a thin-client
using our WebImageViewer and WebThumbnailViewer. This is a live demo using
ADC and our AJAX enabled WebImageViewer.
This is the C# code-behind used for this demo:

Here is the client-side javascript required to process images on button clicks without page postbacks:
<script language="javascript"
type="text/javascript">
atalaInitClientScript("OnPageLoad()");
var
webViewBefore;
function
OnPageLoad()
{
webViewBefore
= <%= webViewBefore.ClientID %>;
webViewBefore.RemoteInvoked
= Invalidate;
}
function
Invalidate()
{
webViewBefore.Update();
}
function
btnHolePunch_onclick() {
webViewBefore.RemoteInvoke("ApplyCommand", new
Array("HolePunchRemovalCommand"));
}
function
btnBorderRemoval_onclick() {
webViewBefore.RemoteInvoke("ApplyCommand", new
Array("AdvancedBorderRemovalCommand"));
}
function
btnLineRemoval_onclick() {
webViewBefore.RemoteInvoke("ApplyCommand", new
Array("LineRemovalCommand"));
}
function
btnInvertText_onclick() {
webViewBefore.RemoteInvoke("ApplyCommand", new
Array("AutoInvertTextCommand"));
}
function
btnSpeckRemoval_onclick() {
webViewBefore.RemoteInvoke("ApplyCommand", new
Array("SpeckRemovalCommand"));
}
function
btnDespeckle_onclick() {
webViewBefore.RemoteInvoke("ApplyCommand", new
Array("DocumentDespeckleCommand"));
}
function
btnDeskew_onclick() {
webViewBefore.RemoteInvoke("ApplyCommand", new
Array("AutoDeskewCommand"));
}
function
btn1To1_onclick() {
webViewBefore.setAutoZoom(0);
webViewBefore.setZoom(1);
}
function
btnFitToWidth_onclick() {
webViewBefore.setAutoZoom(3);
}
</script>
