Dynamsoft TWAIN Products

I have a requirement in that users need to blackout certain confidential information on scanned PDF output generated by WebTWAIN. Is there anyway to allow a user to blackout certain sections of a document once it has been scanned or is this somehting I am going to have to go outside of WebTWAIN to create?

Thanks...

After looking further into this issue, I would assume that the functions outlined below provided by WebTWAIN would allow the above mentioned functionality. However, I am having some trouble in identifying the selected area. Can you please provide me with an example of how these functions would be used to select an area and set the background color?

Thanks...

---------------

ObjectName.Erase(short sImageIndex, Int32 iLeft, Int32 iTop, Int32 iRight, Int32 iBottom)

ObjectName. BackgroundFillColor

I was able to work this out so I thought I would post a quick example here for reference:

var _index, left, right, top, bottom;

frmScan.DynamicWebTwain1.BackgroundFillColor = 000000;
frmScan.DynamicWebTwain1.Erase(_index, left, top, right, bottom);


<script language="javascript" type="text/javascript" event="OnImageAreaSelected(index, iLeft, iTop, iRight, iBottom)" for="DynamicWebTwain1">

_index = index;
top = iTop;
left = iLeft;
right = iRight;
bottom = iBottom;

</script>

<script language=javascript for=DynamicWebTwain1 event=OnImageAreaDeSelected(index)>

_index = null;
top = null;
left = null;
right = null;
botton = null;

</script>
