Drawing a dotted line

[Rene]

I tried searching the newsgroups to see how do you draw a dotted line but I
was unable to find an answer, drawing a straight line is very easy but not a
dotted one.

So the question is, how do I draw a dotted line?

Thank you.

The way this tends to work in page description languages is the most obvious
trickery - draw a bunch of small short lines in a row.

You can select a line style for a pen that includes standard dot, dot-dash
and so-on or create a custom line style. Lines drawn by pens may also have
end-caps shaped like arrows, diamonds or dots.

Look at System.Drawing.Pen and the DashStyle property which contains a
DashStyle enumeration value.

Not bad, if fact not bad at all... but now I need to scale the line so that
the space between the different patterns is bigger, for example I am
currently using the dash-dot style but the dash and dot are so close
together that in a high resolution screen you can barely tell the line is
not a solid line! Is there a way to scale the line spaces or am I going to
have to create a custom style??

Thank you.

Hi Rene,

I think you should do some custom drawing.
For example, you can take Richard's suggestion, do some trickery, draw a
bunch of small short lines combine with some dot.

Custom line styles are easy to create and much simpler that trying to
hand-draw a bunch of individual dots and dashes...

For example...

Pen dp=new Pen(Brushes.Black,1);

dp.DashPattern=new float[]{10f,3f,3f,3f};

e.Graphics.DrawLine(dp,0,0,100,100);
