I want to scan without WIA dialog in Monochrome;
But when im setting
ImageEnView1.IO.AcquireParams.PixelType:=ieapMonochrome;
it have no effect on scanning results.
Is there something i misunderstood ? |

small clarification:
Everything works fine when ImageEnView1.IO.AcquireParams.VisibleDialog:=True.
I can set Monochrome in Windows Scanner-Setup dialog box and everything works fine.
But it unacceptable with ADF.
Each time ADF scanning a new page, it showing this dialog.
while FeederLoaded do
begin
ImageEnView1.Clear;
ImageEnView1.IO.Acquire;
end;
Im using HP MFP 2727 with ImageEn 4.1.4 |

Hi
Specifying a PixelType will set a few WIA properties (WIA_IPA_BITS_PER_CHANNEL and WIA_IPA_CHANNELS_PER_PIXEL), but it is up to the driver to ensure they are used.
It may be better to apply a color reduction after the acquisition.
