Hi. I wrote a small free application that converts image files to PDF documents. When using it on a BMP file, one user encountered this error: Code: NotImplementedException: Image format not supported. at PdfSharp.Pdf.Advanced.PdfImage.InitializeNonJpeg() at PdfSharp.Pdf.Advanced.PdfImage..ctor(PdfDocument document, XImage image) at PdfSharp.Pdf.Advanced.PdfImageTable.GetImage(XImage image) at PdfSharp.Pdf.PdfPage.GetImageName(XImage image) at PdfSharp.Drawing.Pdf.XGraphicsPdfRenderer.GetImageName(XImage image) at PdfSharp.Drawing.Pdf.XGraphicsPdfRenderer.Realize(XImage image) at PdfSharp.Drawing.Pdf.XGraphicsPdfRenderer.DrawImage(XImage image, Double x, Double y, Double width, Double height) at PdfSharp.Drawing.XGraphics.DrawImage(XImage image, Double x, Double y) at PdfSharp.Drawing.XGraphics.DrawImage(XImage image, Int32 x, Int32 y) I was skeptic at first, but he sent me the file and it is correct and accurate. It's a BMP file, which can even be displayed by the basic viewer of TotalCommander, pressing F3. Debugging the application I found the LOC where the exception is thrown. It's the one where "DrawImage" is called: Code: PdfDocument doc = new PdfDocument();
doc.Pages.Add(new PdfPage()); XGraphics xgr = XGraphics.FromPdfPage(doc.Pages[0]); XImage img = XImage.FromFile(source); //adjust page size to fit image if (doc.Pages[0].Width < XUnit.FromPoint(img.Size.Width)) doc.Pages[0].Width = XUnit.FromPoint(img.Size.Width); if (doc.Pages[0].Height < XUnit.FromPoint(img.Size.Height)) doc.Pages[0].Height = XUnit.FromPoint(img.Size.Height); xgr.DrawImage(img, 0, 0, img.Size.Width, img.Size.Height); doc.Save(destinaton); doc.Close(); I tested with PDFSharp versions 1 and 1.20 beta and the result is the same. If needed I can provide the BMP file that causes this. Thanks for your time and effort and keep up the good work! |

Hi! We need the BMP to investigate this. I sent you a PM. |

The image format is: Format16bppRgb555 (Specifies that the format is 16 bits per pixel; 5 bits each are used for the red, green, and blue components. The remaining bit is not used.) I knew there was such a format but didn't know how to create it. I'll let you know when it's implemented. |
