about painting where I don't specify a rectangle

[Tony Johansson]

Hi!

If I set sf.Alignment = StringAlignment.Near; it will draw at the far left
which is correct
But when I set the sf.Alignment = StringAlignment.Far; in the code below no
text is displayed.
so I wonder if I don't specify a rectangle what is the area that .NET will
use to draw ?

Graphics g = this.CreateGraphics();
FontFamily fm = new FontFamily("Arial");
Font f = new Font(fm, 10);
StringFormat sf = new StringFormat();
sf.Alignment = StringAlignment.Near;
g.DrawString("GDI+ in Microsoft .NET", f, Brushes.Red, 0, 0, sf);

The rectangle that contains the text you asked it to draw.

"Near" and "Far" are just "text-direction-agnostic" descriptions of
alignment. But if you know the text direction being used, you can tell
what alignment corresponds to each. For left-to-right text, "Far" is
just "right-aligned". So when you tell Graphics to draw your text
right-aligned at point (0, 0), it draws the text so that the right edge
of the text winds up at that point.

You'll see the text being drawn if you specify a location to draw it
that is not at the very left edge of the visible area of the Graphics
instance.
