I am seeking help using a XML file that shows a signature and uses point refrences. I want to convert that XML file to a bmp file. I want to allow the user to enter a file name and location for new file and then create the bmp from the xml. I am very new to C# and need some help badly. Here is a sample of the signature file. Any help would be greatly appreciated. You can contact me at xxxxxxxxx@hotmail.com. Thx.

Removed email. Please don't post your email address here. People will reply here if they can help.

So exactly what problem are you having? However I question the approach of trying to draw the signature with line segments embedded in a string.
mtechniques 17-Jul-11 2:01am
   
this is the way the data is being stored in the xml by a vendor. I want to create a bmp file of that signature and be able to add it to crystal reports, etc.

Are the points connected, like are those lines or just points?
mtechniques 17-Jul-11 14:08pm
   
they are lines that form a signature from a signature pad. The segments are started every time the user picks up the stylus up off the pad

You can use System.Drawing to do the following:

First, create an empty bitmap System.Drawing.Bitmap of appropriate size.

Using obtained bitmap instance, create and instance of the class System.Drawing.Graphics. Use its static factory method System.Drawing.Graphics.FromImage, pass your bitmap instance as a parameter. You got an instance of the Graphics object to draw on the bitmap.

Interpret your XML as a sequence of line segments and use segment data to draw on the bitmap canvas obtained on the previous step. Use methods System.Drawing.Graphics.DrawLine and/or System.Drawing.Graphics.DrawLines, etc.

See:

Sensible approach, my 5

Thank you, Espen.

I think using GraphicsPath[^], but otherwise proceed as outlined by SAKryukov, could be an efficient way to implement your solution.

Best regards

That is yet another method I tried to cover by "etc.", via Graphics.DrawPath. My 5.
