Post subject: | Is it possible to highlight the text of a PdfTextField? |
Hello everyone, I have been struggling to figure out how to highlight a textfield. My current code looks like this: public static void highlightPDF(PdfAcroForm form, string fieldName) { PdfAcroField field = form.Fields[fieldName]; PdfTextField txtField; if ((txtField = field as PdfTextField) != null) { txtField.BackColor = PdfSharp.Drawing.XColors.Yellow; } } Nothing happens with this solution however, the variable is showing that it is the color yellow but it doesn't appear that way on my pdf file. I have tried finding the position of a textfield then drawing a rectangle over it but that solution fell short since it only works for the first element on my pdf for some reason. Any advice would be greatly appreciated. |

If anyone runs into this problem, here is what I did: PdfTextField txtField = (PdfTextField)field; PdfArray fieldRect = (PdfArray)txtField.Elements.GetValue(PdfAnnotation.Keys.Rect); PdfRectangle rect = txtField.Elements.GetRectangle(PdfAnnotation.Keys.Rect); XRect rectangle = new XRect(rect.X1, rect.Y1, rect.Width, rect.Height); XRect pdfPosition = gfx.Transformer.WorldToDefaultPage(rectangle); XBrush backgroundBrush = new XSolidBrush(XColor.FromArgb(64, XColors.Yellow)); XBrush borderBrush = new XSolidBrush(XColor.FromArgb(128, XColors.Yellow)); gfx.DrawRectangle(backgroundBrush, pdfPosition); gfx.DrawRectangle(borderBrush, pdfPosition); |
