ADR w/ multipage TIFFs?

Post by andypl » Fri Nov 13, 2009 5:36 pm

How well - if at all - does ADR work with multipage TIFFS? Do I need to compare the pages individually or will the ADR engine compare pages to pages?

Any code examples would be appreciated?

Also - any hints for getting ADR to work with your typical black text on a white page business forms? I'm having it return the incorrect matching template on documents that look pretty different to my eye!

Thanks
Andy

Hi Andy,

ADR engine considers a Template as a single page document. Therefore, if you want to make multipage document comparison you have to create a different template for each page.

Code: Select all

        Dim PageCount As Integer = oGdPictureImaging.TiffGetPageCount(ImageID)
        Dim TemplateArray(PageCount) As Integer

        For i As Integer = 1 To PageCount
            oGdPictureImaging.TiffSelectPage(ImageID, i)
            TemplateArray(i - 1) = oGdPictureImaging.ADRCreateTemplateFromGdPictureImage(ImageID)
        Next

Could you attach some of these documents ?

Kind regards,
