| Post subject: | Extra lines in PDF when printed |
Hello, I'm not convinced this is a bug, as it may be a problem with some printer drivers or it may be the case that I am unwittingly violating some precondition. (This issue is also under discussion on Stack Overflow at: http://stackoverflow.com/questions/8995 ... en-printed) I created a PDF using PDFSharp. I can't attach a zipped copy because the zip is still 756 KiB which exceeds the forum limit. Anyone who wants to see it can email me at douglas.mcclean@gmail.com. When I print it (to my Brother HL 5140 laser printer, or to the XPS printer, but not to PDFCreator) it ends up with some extra lines. I've also taken a pair of screenshots, which are at http://i.imgur.com/E7452.png. The printed copy contains an extra line segment (actually two, a skinny white one atop a wider black one in a style commonly used to depict roads) that runs from top center to bottom left. Does anyone know why this happens, whether it is a bug in PDFSharp or a problem with my geometry, or have any idea how to go about debugging something like this? |

Adobe Reader X and Acrobat 8 display the file correctly, printing on an HP LaserJet also draws the line. Looks as if the line is drawn while it should be a move (with "pen up"). I forwared the file to Stefan, maybe he can say more. |

It's independent of the exact geometry. The same thing happens even though I run the geometry through a simplifier first to reduce the file size. |
