In version 1.50, I am trying to use XImage.FromGdiPlusImage() and it is not available for the selected image frame.

Image img = Image.FromFile(@"C:\\Multi_page.tif");
string destination = @"C:\\Multi_page.pdf";
PdfDocument document = new PdfDocument();

for (int pageIndex = 0; pageIndex < img.GetFrameCount(FrameDimension.Page); pageIndex++)
{
img.SelectActiveFrame(FrameDimension.Page, pageIndex);
PdfSharp.Drawing.XImage xImage = PdfSharp.Drawing.XImage.FromGdiPlusImage(img);
var page = new PdfPage();
if (xImage.PixelWidth > xImage.PointHeight)
{
page.Orientation = PageOrientation.Landscape;
}
else
{
page.Orientation = PageOrientation.Portrait;
}

document.Pages.Add(page);

PdfSharp.Drawing.XGraphics xgr = PdfSharp.Drawing.XGraphics.FromPdfPage(document.Pages[pageIndex]);
xgr.DrawImage(xImage, 0, 0);
}

What is the alternative that should be used?

Thanks so much!!

Where's the problem?
You have to take the GDI+ build of PDFsharp if you want to use GDI+-specific methods like XImage.FromGdiPlusImage().

What's the point of comparing PixelWidth and PointHeight?

TH-Soft: How do you select the GDI+ build of PDFSharp? It is not an option with the Nuget package.

As for the PixelWidth and PixelHeight, it is used to set the page orientation.

Thanks,
Marty

Try one of those:
https://www.nuget.org/packages/PDFsharp-gdi/
https://www.nuget.org/packages/PDFsharp-MigraDoc-GDI/

I don't understand why you compare PixelWidth and PointHeight. Comparing PixelWidth with PixelHeight makes sense.

TH-Soft: Thanks for the reply. I didn't know those options were possible.

I made a typo. It should have been PixelHeight instead of PointHeight. My goof.
