.NET Forum / Windows Forms / Drawing / March 2008draw a line from 0 to 52 does the last pixel of the line show?
If I have a panel with a client sizes of 52x52 and I draw a line from 0 to 52 does the last pixel of the line show? Thanks in advance No because the window pixel range is zero based so the reange will be from 0-51 = 52 pixels wide.

Not like a ruler where 0-1 is 1 inch; not 2. Seems I remember years ago that Petzold said that with the win32 0-1 was one pixel, but I'm not sure about that.

By changing the page units to, say inch, point or millimeter the world units will correspond to the chosen standard.
