Post subject: | Drawing Text, Transparent brush is not Transparent PDFSharp |
I am using the WPF build of PDFSharp, version 1.32.2608.0. I am trying to draw transparent text over the top of an image (over the top of an image of text, so that the user can select the text). I tried this: Code: gfx.DrawString(text, font, XBrushes.Transparent, x, y); but the drawn text was white and clearly visible over the text in the image. I tried creating my own brush with full transparency: Code: new XSolidBrush(XColor.FromArgb(0,255,255,255) same result, if I changed the custom brush to a color other than white, it just draws the color and ignores the transparency value. I also tried using 255 as the transparency value just in case, same result. How do I draw ACTUAL transparent text? Or some workaround that accomplishes what I said at the beginning? Any help is appreciated. |

Does the problem still exist with PDFsharp 1.50 RC2a? |

Did you set the PDF version to 1.4 or higher? Code: if (document.Version < 14) document.Version = 14; Source: http://pdfsharp.net/wiki/ColorsCMYK-sample.ashx |
