Hi, i am new to programming...and trying to write a code to draw a line and arrowheads to be given to that line on Adobe PDF document. Maybe there will be some text on the side of the page. I am successfully draw a line but then unable to draw a arrow line. So, is it possible to draw line with arrow head on a PDF document? Is there a nice way to draw such arrowhead? Thanks so much for your help on these!

To add highlights, freehand drawing, or sticky notes to PDF document in c# programming, you may need to integrate an editing library. Then you can add editing marks to indicate changes that you want in PDF document. Certainly, to add text comment on PDF file, annotation should be considered. Hope this suggest would be helpful. Just search a such solution on google.

If annotation is considered, you just need to draw the start and end points, and define one end of the line as an arrowhead. Moreover, drawing in C# is achieved using the Graphics Object that takes much of the pain out of graphics drawing by abstracting away all the problems of dealing with different display devices and screens resolutions. Programmer merely needs to create a Graphic Object and tell it what and where to draw.

Suggest you to use XsPDF basic library sdk. Its XGraphics class allows you to draw a line and put arrow heads in c# programming. Also, you are able to add text comment to anywhere you want on PDF document. Check it out.
