How to draw text at Line? How to calc direction for text placed on the line?

Anonymous — Thu, 26 Jul 2012 20:36:12 GMT

I did DrawableOverrule instance and override WorldDraw method.
In this method I have checked:

public override bool WorldDraw(Drawable d, WorldDrawwd)
{
if (d isLine)
{
Line line = (Line)d;

Next I want to draw text placed on the line and I did:

wd.Geometry.Text(line.StartPoint, normal, direction

Question is - how to calculate required direction for text that text should be placed on the line? Is it easy way to do it?

Thanks!

The Line.Delta property returns a vector along the direction of the line.
