Insert bitmaps or GIFs into a PDF

[Mark Oliver]

Hi,

I'm trying to insert bitmaps or GIFs into a PDF Document that I am creating in a .NET Core Application (.NET Core 3.1, it's an Azure Function).  I can insert PNGs without problem but if I try to insert a bitmap I get an exception ("Only JPEG and PNG images are supported").

The documentation on Syncfusion's web site (https://help.syncfusion.com/file-formats/pdf/working-with-images) suggests that this is possible.  What else do I need to do to get bitmaps (and the other file formats the documentation states is supported) working?

My sample code is based on Syncfusion's sample and is as follows:

public void ValidateAndConvert(Stream inputStream, Stream outputStream, string filename)

        {

            try

            {

                var pdfDocument = new PdfDocument

                {

                    PageSettings = { Size = PdfPageSize.A4 }

                };

                PdfPage pdfPage = pdfDocument.Pages.Add();

                // Get page size to draw image which fits the page

                SizeF pageSize = pdfPage.GetClientSize();

                // Create PDF graphics for the page

                PdfGraphics graphics = pdfPage.Graphics;

                

                // Load the image from the disk

                PdfBitmap image = new PdfBitmap(inputStream);

                // Draw the image

                graphics.DrawImage(image, new RectangleF(0, 0, pageSize.Width, pageSize.Height));

                pdfDocument.Save(outputStream);

            }

            catch (Exception e)

            {

                this.Logger.LogWarning($"Exception error while processing file {filename}: {e.Message}");

            }

        }

}
