Hi all,

I don't know where to start.

I would like to create an interface on web to let user scan their document and save it on server.

Can someone help me?

You can try something like that to acquire an image from a web page and save the resulting image into a distant ftp server:

Code: Select all

<title>Document sans nom</title> 


function OpenSource(){ 
var oTWAIN = new ActiveXObject('gdtwain.twain');  



PS: You have to see the SaveToFTP() documentation method: ... ToFTP.html

Best regards,

Thanks for the code.

Is it possible to display the image on the web page once the scanning is done?

Yes but you need to use the GdPicture Pro or the GdViewer [Pro] component to do that. The GdTwain component was not designed to display image.

A question very similar to the above. I need to capture an image on the client (using javascript) and then post it back to the server to be processed by c# code behind. I do not want to save to an ftp site, ideally, I would like to pass the image in a hidden form field. Would you be able to provide a code example (javascript) of saving the image as a byte array or string?
I have tried both with no success.

Thank You!!

I am also looking for a way to save the image back to a server through the post. I have not been able to figure a way to get a handle on the image to upload it. Any examples?

I have a web interface and I am able to load the twain image into a html x-oleobject through your javascript sample. I want to transfer that file to my java side of the project and then using Java I will upload that file to server.
Please let me know how to do that,
