Post subject: | Drawing DrawMatrixCode : image is null |
Hello, I can draw and write in my PDF without any problem. Now, I want to generate a dataMatrix in a pdf with PdfSharp. A problem occured when I run the DrawMatrixCode // Version : 1.50.5147 Code: using PdfSharp.Drawing; using PdfSharp.Drawing.BarCodes; using PdfSharp.Pdf; Code: PdfDocument document = new PdfDocument();
document.Info.Title = "Sample title"; PdfPage page = document.AddPage(); page.Width = XUnit.FromMillimeter(500); page.Height = XUnit.FromMillimeter(500); XGraphics gfx = XGraphics.FromPdfPage(page); CodeDataMatrix dm = new CodeDataMatrix("test", 26) { Size = new XSize(XUnit.FromMillimeter(15), XUnit.FromMillimeter(15)) }; gfx.DrawMatrixCode(dm, XBrushes.DarkBlue, new XPoint(100, 100)); // // ----> System.ArgumentNullException // HResult=0x80004003 // Message=The value can't be // Nparameter name : image // Source=PdfSharp // call stack : // à PdfSharp.Drawing.XGraphics.DrawImage(XImage image, Double x, Double y, Double width, Double height) // à PdfSharp.Drawing.BarCodes.CodeDataMatrix.Render(XGraphics gfx, XBrush brush, XPoint position) // à PdfSharp.Drawing.XGraphics.DrawMatrixCode(MatrixCode matrixcode, XBrush brush, XPoint position) |
