Hi all,

I would like to know if a deskew function exists for GdTwain.
If yes, which function?

Thx

Hi,

You can try to call TwainSetAutomaticDeskew(True) before acquiring an image. However this methods will works only if your device gets this functionality.

Thanks for your help

I put TwainSetAutomaticDeskew(True) before acquiring an image and it does not work.

Code: Select all

Set oTWAIN = CreateObject("gdtwain.twain")

oTWAIN.SetLicenseNumber("0012345678910111213141516") 'Demo code version

oTWAIN.TwainOpenDefaultSource
oTWAIN.TwainSetAutomaticDeskew(true)
nImageID = oTWAIN.TwainAcquireToImageID
If nImageID <> 0 Then
  oTWAIN.SaveAsPdf ("D:\Ufile\www\gdtwain\gdtwaintest3.pdf")
  oTWAIN.CloseImage (nImageID)
  document.write "Save D:\Ufile\www\gdtwain\gdtwaintest3.pdf completed"
End If

oTWAIN.TwainUnloadSourceManager

I can't found any description of this device which says that is support the Automatic Deskew by Hardware

However an Automatic Deskew method is into my roadmap. But now, I can't give a date of release (maybie end of October or few days before but is not sure).
