You'll have to post the tiff for inspection.

Subject: Re: [iText-questions] Converting Fax Tiff to PDF
Thanks again for the response. I’ve looked through the documentation and
tried the following:
Dim img = iTextSharp.text.pdf.codec.TiffImage.GetTiffImage(tifArray, pageno)
Dim xValue As String = img.DpiX.ToString
Dim yValue As String = img.DpiY.ToString
I converted to string just to see what it returned. However, it returned an
x value of 204 and a y value of 196 which seems abnormally low and out of
proportion. I think I’m barking up the wrong tree but I didn’t find anything
else that looked like it would return a dpi.

You'll have to scale in both axis with different values. Use
iTextSharp.text.pdf.codec.TiffImage. This will return an iTextSharp.text.Image
with the right X and Y dpi information.

Are you saying do without the line that scales the image?

Load the image directly from the tiff or you'll lose the dpi information.

Subject: [iText-questions] Converting Fax Tiff to PDF
Hello Everyone and thanks for your help in advance. I am developing an
application with iTextSharp to transform inbound faxes to PDF files. However,
when converted to PDF files, some of the faxes do not display properly, for
example they appear shortened on the page and out of correct resolution. All
of the text appears, but squashed on the page. It appears that my code does
not properly account for various dpi settings of the inbound faxes, but I am
unsure how to account for this. Here is my code:
' creation of the document with a certain size and certain
margins
Dim document As New
iTextSharp.text.Document(iTextSharp.text.PageSize.A4, 0, 0, 0, 0)
' creation of the different writers
Dim writer As iTextSharp.text.pdf.PdfWriter =
iTextSharp.text.pdf.PdfWriter.GetInstance(document, New
System.IO.FileStream(DestinationFile, System.IO.FileMode.Create))
' load the tiff image and count the total pages
Dim bm As New System.Drawing.Bitmap(SourceFile)
Dim total As Integer =
bm.GetFrameCount(System.Drawing.Imaging.FrameDimension.Page)
document.Open()
Dim cb As iTextSharp.text.pdf.PdfContentByte =
writer.DirectContent
For k As Integer = 0 To total - 1
bm.SelectActiveFrame(System.Drawing.Imaging.FrameDimension.Page, k)
Dim img As iTextSharp.text.Image =
iTextSharp.text.Image.GetInstance(bm, System.Drawing.Imaging.ImageFormat.Bmp)
' scale the image to fit in the page
img.ScalePercent(72.0F / img.DpiX * 100)
img.SetAbsolutePosition(0, 0)
cb.AddImage(img)
document.NewPage()
Next
document.Close()
Any help would be greatly appreciated.
