I to draw a string at an arbitrary angle

When I am using Graphics.DrawString, I can only draw a string either
horizontally or vertically. Is the a way to draw under arbitrary angle -
parallel to some line?

I would appreciate a code sample.

Thanks,

Val

Yes, but I note in the sample output provided that the rotation of the
text appears to be around the upper left corner of the text 'frame'; is
there a convenient manner in which the rotation can occur based on the
centre left of the text 'frame', so that the text drawn at zero (0) and
180 degrees are aaligned?

As with all matrix operations things are best done around the origin.

You can rotate around any point drawing the text at a position that orients
it correctly.

For example...

Matrix mx=new Matrix(1,0,0,1,0,0);

mx.Rotate(45,MatrixOrder.Append);

mx.Translate(this.ClientRectangle.Width/2,
this.ClientRectangle.Height/2,MatrixOrder.Append);

e.Graphics.Transform=mx;

SizeF sz=e.Graphics.MeasureString("Hello
World!!",this.Font,1024,StringFormat.GenericTypographic);

e.Graphics.DrawString("Hello
World!!",this.Font,Brushes.Black,-sz.Width/2,-sz.Height/2,StringFormat.GenericTypographic);

return;
