TwainOptions
Properties
Dsm
The DSM version of TWAIN to use. Drivers/Windows usually come bundled with an Old version, while NAPS2 itself provides a New version. This is the most common thing to try changing if you have compatibility issues. You can also use NewX64 to access 64-bit TWAIN drivers but usually they don't exist, everything is generally 32-bit.
public TwainDsm Dsm { get; set; }Property Value
IncludeWiaDevices
Whether to include include devices that start with "WIA-" in GetDeviceList. Windows makes WIA devices available to TWAIN applications through a translation layer. By default they are excluded, since NAPS2 supports using WIA devices directly.
public bool IncludeWiaDevices { get; set; }Property Value
ShowProgress
Whether to show the TWAIN progress UI. This only matters when ScanOptions.UseNativeUI is false (otherwise the full UI is shown regardless).
public bool ShowProgress { get; set; }Property Value
TransferMode
The transfer mode used for TWAIN, either Native or Memory. By default Memory is used.
public TwainTransferMode TransferMode { get; set; }
