How can drawString method be used for writing diagonal way.

Question

Hi,

I am using c# 2005 i want to write string diagonally on image. But by default c# provides the option to write horizontally or vertically.

how we write diagonally?

Thanks

Answer 1

Do a Graphics.rotateTransform before the drawString call. Don't forget to reverse the change afterwards, as Phil Wright points out.

Answer 2

You can use the RotateTransform and TranslateTransform that are available on the Graphics class. Because using DrawString is GDI+ the transforms affects the drawing. So use something like this...

g.RotateTransform(45f);
g.DrawString("My String"...);
g.RotateTransform(-45f);

Don't forget to reverse the change though!

Answer 3

There is another way to draw a text vertically which is built in the C#. There is no need of explicit graphics transformation. You can use the StringFormat class. Here is a sample code which draws a text vertically:

StringFormat sf = new StringFormat(); sf.FormatFlags = StringFormatFlags.DirectionVertical; e.Graphics.DrawString("My String", this.Font, Brushes.Black, PointF.Empty, sf);
