ScaleToFit problem when image rectangle is wider than document

[LMM]

I am adding JPGs of various sizes to the PDF I am creating.  While testing I discovered that 1 particular JPG wouldn't resize, and without throwing an error, allowed the program to complete but not save the document.

I think I've found the problem.  When the image is wider than the document the document won't print even after using ScaleToFit.  The dimensions of the rectangle never change.  I have examples of the dimensions of the document and the image before/after Scale to Fit, and the couple of lines of code from my program.

_document.PageSize.Base{Rectangle 612x792}

Image before ScaleToFit

artImage{Rectangle 809X280}
artImage.PlainHeight 280.0
artImage.PlainWidth 809.0
artImage.ScaledHeight 280.0
artImage.ScaledWidth 809.0


Image after ScaleToFit

artImage{Rectangle 809X280}
artImage.PlainHeight 179.975281
artImage.PlainWidth 520.0
artImage.ScaledHeight 179.975281
artImage.ScaledWidth 520.0


Program code

float imgHeight = 200.0f;
artImage.Alignment = Image.ALIGN_LEFT;
artImage.ScaleToFit(_document.Right - (_document.RightMargin + 20.0f), imgHeight);


Is this in fact the problem (rectangle size) and if so, is there a way around it?

No problem there, the rectangle is the original image size and never
changes. What changes is the the ScaledHeight and ScaledWidth. What do you
mean by "the document won't print"?

I misspoke.  I am creating the document as a MemoryStream, create the document, close the document so the pageevents run, and then reopen to use PdfStamper, etc...

The program works fine, unless I have an image wider than the document.  When that happens, I get an error (Rebuild failed: Input string was not in a correct format.; Original message: PDF startxref not found.) when 'PdfReader reader = new PdfReader(pdfRead);' tries to execute.  Consequently the program jumps to my Catch, and the document never gets saved to the SQL table.

Here is some additional code:


MemoryStream ms = new MemoryStream();
PdfWriter writer = PdfWriter.GetInstance(document, ms);

MyPageEvents pagevent = new MyPageEvents();
writer.PageEvent = pagevent;
           
document.Open();

***** add to document *****

 document.Close();

 byte[] pdfRead = ms.GetBuffer();

 PdfReader reader = new PdfReader(pdfRead);

If the image is wider than the page it may not be added and unless you have something else in the page it will throw a "document has no pages exception". I suspect that you are ignoring an exception.
