Hi,

I implemented a dialog in my C# project using IEvolution 4.0.1.

My dialog should enable WIA and TWAIN scanning without calling another system dialog. The offered Class "TWainParams" contains many properties for TWAIN based scanning. Exist such a class for WIA? If not where can I set WIA parameter (especially the usage of a feeder)?

Thanks


// ...
private IEViewer Viewer { get; set; }

public void ScanTWain(bool sysDialog) 
{
 // set properties in Viewer.Image.TWainParams
 Viewer.Image.AcquireFromTWain();
 Viewer.Image.TWainParams.FreeResources();
}

public void ScanWIA(bool sysDialog)
{
 // TODO: set properties
 Viewer.Image.AcquireFromWIA();
}

// ...

Hi,
at the moment there aren't WIA properties to set in IEvolution. It is only possible to select a device and scan from it.

Hi,
Ok, then I've to use TWAIN.
Is a solution for WIA based scanning planned for the next versions?

Hi,
yes, it is planned to add (not for next version) WIA properties to IEvolution.
