Post subject: | PDFsharp-Questions about font settings and image coordinate |
I encountered two problems: The first question is why the font is not changed after embedding the value into the pdf Code: XFont font2 = new XFont("DFKai-SB", 12, XFontStyle.Regular); XmlDocument xml = new XmlDocument(); xml.LoadXml(nodeList.Item(i).OuterXml); MemoryStream modifiedStream = new MemoryStream(); PdfDocument inputDocument = PdfReader.Open(new MemoryStream(pdfTemplate), PdfDocumentOpenMode.Modify); PdfPage page = inputDocument.Pages[0]; XGraphics gfx = XGraphics.FromPdfPage(page); // inputDocument.AddCharacters(font2); foreach (XmlNode node in xml.DocumentElement.ChildNodes) { if (node is XmlElement) { string fieldName = string.Format("topmostSubform[0].Page1[0].{0}[0]", node.Name); PdfTextField field = inputDocument.AcroForm.Fields[fieldName] as PdfTextField; if (field != null) { field.Font = font2; field.Value = new PdfString(node.InnerText); } } } The second question is how to set up this coordinate system? What are the units of the x-axis and y-axis? Is it (pixel)? Code: gfx.DrawImage(image, posx, newPosY, image.PixelWidth * 0.3, image.PixelHeight * 0.3); After I converted the itextsharp program to pdfsharp, I found that the image position was not in the correct position. ------------ Thanks to everyone who offered to answer questions |
