c# - How to get the exact Font out of Fontfamily? -

i want create picturebox adapts shape string of font. need can later create texts , lay on axwindowsmediaplayer control.

therefore created following class:

using system; using system.collections.generic; using system.linq; using system.text; using system.threading.tasks;  using system.windows.forms; using system.drawing;  namespace myproject {     class shapedpictureboxes : picturebox     {         public shapedpictureboxes()         {             this.paint += this.shapedpaint;         }      void shapedpaint(object sender, painteventargs e)     {         system.drawing.drawing2d.graphicspath graphicspath = new system.drawing.drawing2d.graphicspath();   font font = new font("arial", 14f); float emsize = e.graphics.dpiy*font.size/72;         graphicspath.addstring(text, new fontfamily("arial"), (int)system.drawing.fontstyle.regular, emsize, new point(0,0), new stringformat());          e.graphics.drawstring(text, font, brushes.red, new point(0, 0));          this.region = new region(graphicspath);     }      public string text = "here comes sun, doo da doo do"; }  } 

the problem is, "graphics.drawstring" not match graphicspath.addstring, because fontfamily isn't same font. how can match them?

so: how can convert fontfamily font or viceversa?

this how looks like:

you need account fact font size specified in units of points, addstring() size specified in device units.

you can convert units follows:

font font = new font("arial", 14f, fontstyle.bold); float emsize = e.graphics.dpiy * font.size / 72; // here's conversion. graphicspath.addstring(text, new fontfamily("arial"), (int)system.drawing.fontstyle.bold, emsize, new point(0, 0), new stringformat()); 

note i'm passing calculated emsize addstring() instead of passing 14f.
