TWAIN progress

Post by dixus » Thu Feb 18, 2010 1:22 pm

Is there a way to get the current progress of the scanning process?

The twain ui shows a progress bar. On a multipage scanner it would be perfect to have the possiblility to get the status of the scan process.

This is very important for our project... So if not implemented but possibly, could you add something like that:

Code: Select all


//add your delegate to GDLib event handler
GdLib.TwainDocScannedEvent+=OnDocScanned;

//receive events from gd
public void OnDocScanned(object sender, EventArgs e)
{
    GDPictureEventArgs gde = (GDPictureEventArgs )e;
    this.Text = gde.Info;
    progressBar1.Value = gde.PercentDone;
}
A second way would be a callback function.

Important is a way to show the user the progress of the process...

Thanks in advance,

dix

Hi,

Unfortunately we can't implement that. There is nothing in TWAIN specs defining this kind of callback.

With best regards,

Loïc
