Hi

i have some trouble on device settings via UI. How come that when i set the following to:
Plugin.IfFeederEnabled = true; // ADF
Plugin.IfDuplexEnabled = true; // Duplex
Plugin.PixelType = 0
Plugin.Brightness = 50
Plugin.Contrast = 50
Plugin.Resolution = 200

and when i alert the values it became

Plugin.IfFeederEnabled = false; // ADF
Plugin.IfDuplexEnabled = false; // Duplex
Plugin.PixelType = 2
Plugin.Brightness = 0
Plugin.Contrast = 0
Plugin.Resolution = 100 ?

Code:

function btnScan_onclick()
{
     var Plugin = document.embeds[0];
     var i;
     Plugin.SelectSourceByIndex(document.getElementById("source").selectedIndex);
          
     Plugin.CloseSource();    
     Plugin.OpenSource();
     Plugin.IfShowUI = false;
     Plugin.IfFeederEnabled = true; // ADF
     alert(Plugin.IfFeederEnabled);
     Plugin.IfDuplexEnabled = true; // Duplex
     Plugin.PixelType = 0;
     alert(Plugin.PixelType);
     Plugin.Brightness = 50;
     alert(Plugin.Brightness);
     Plugin.Contrast = 50;
     alert(Plugin.Contrast);
     Plugin.Resolution = 200;
     alert(Plugin.Resolution);
     Plugin.IfDisableSourceAfterAcquire = true;
     Plugin.AcquireImage();
}

what's the possible problem? I don't think that is my code or is it the device? because as of now I'm using a webcam(for testing) but this code will run in CANON DR-9050C.

Thanks in advance. I'm looking for your asap response.

Cheers!

Hi katie,

Thank you for the detailed info.

The code seems all right.

Please check whether the webcam is using a TWAIN-compatible driver. For more info, please check out the link below:

If the device is not using a TWAIN driver, the methods/properties/events of Dynamic Web TWAIN may not support it.

Please keep me updated on this.

Thanks Catherine.

I can acquire image from the webcam using the twacker, but still it is default in the values that I was mentioned before.

Is there an instance that the methods/properties/events of Dynamic Web TWAIN may not work even the device is twain compatible?
If yes,how can I assure if the code will work in the actual device?

Dynamic Web TWAIN is based on TWAIN Specification 1.9. Normally, if a device is completely TWAIN compatible, it's supported by Dynamic Web TWAIN. Up to now, we haven't encountered such a TWAIN-compatible driver which is not supported by Dynamic Web TWAIN.
