Page height

[dcoffey]

Im having an issue, no matter what I set the page size, it makes it 1400

I want to use a4 (8.5 x11)

here is my code Im playing with

Code: Select all

Dim nImageID As Integer

        If Imaging1.TwainOpenDefaultSource() Then

            InitScanConfig()

            Imaging1.TwainSetCurrentResolution(100)
            Imaging1.TwainSetCurrentPixelType(GdPicturePro4.TwainPixelType.TWPT_BW) 'BW
            Imaging1.TwainSetCurrentBitDepth(1) ' 1 bpp
            Imaging1.TwainSetPaperSize(1) ' have tried everything here
            Imaging1.TwainSetAutoFeed(True) 'Set AutoFeed Enabled
            Imaging1.TwainSetAutoScan(True) 'To  achieve the maximum scanning rate

            While Imaging1.CreateImageFromTwain(Me.Handle.ToInt32) <> 0
                nImageID = Imaging1.GetNativeImage
                If nImageID <> 0 Then
                    count += 1
                    Call Imaging1.SaveAsTiff(My.Application.Info.DirectoryPath & "\acquire" & Str(count) & ".tiff")
                    Call Imaging1.CloseImage(nImageID)
                End If
            End While
            Imaging1.Crop()
            Call Imaging1.TwainCloseSource()
            MsgBox("Done !")
        Else
            MsgBox("can't open default source, twain state is: " & Trim(Str(Imaging1.TwainGetState)))
        End If

Hi,

I don't understand what is your problem.

What would you say by

Im having an issue, no matter what I set the page size, it makes it 1400

Best regards,

what I mean is, it is scanning 8x14 page, even though I tell it to only scan a 8x11 page
So all the scans have an extra 3" of white space at the end.

Hi,

Your scanner does probably not support this format. What is the returned value of the Imaging1.TwainSetPaperSize(1) call ?


PS you can check the supported paper format like that:

Code: Select all

For ncPt = 1 To Imaging1.TwainGetAvailablePaperSizeCount
      MsgBox Imaging1.TwainGetAvailablePaperSizeNo(ncPt)
Next ncPt
