Hi all,

I'm trying to get the actual size of a string using a specific font. To
acomplish this task I use the Graphics.MeasureString that returns a Size
object. The problem is that the Size object returned is bigger that the
string, rather than the exact string size.

And this difference isn't the same if I change the font facename. Does
anybody is having the same kind of problem?

Cheers,

when you say "bigger" do you mean vertically, horizontally, or both?

I am using MeasureString and it is working just fine:

I use it like:

SizeF c =3D (SizeF) g.MeasureString(iCount.ToString(), base.Font);

where g is the graphics object, iCount.ToString() represents the string
I am measuring and base.Font is the font to use to measure it.

Hi Chris,

I don't know why you use it, but I need it to align vertically a text with a
line previous drawn.
I doesn't align properly, so I have to subtract 3 from the returned size
height.

Could you post code so that we can see how you are using it?

Rick,

If I remove the -3 in line 11 the string is draw above the line draw in line
23.

1 ...
2
3 Font font = new Font(FontName, mark.FontSize);
4
5 SizeF size = Graphics.MeasureString(mark.Description, font);
6 float fPosY = GetPosY(mark.Value);
7 float fPosX = DrawArea.Left - (2 + size.Width);
8
9 Brush brush = new SolidBrush(mark.Color);
10
11 Graphics.DrawString(mark.Description, font, brush, fPosX, fPosY -
(size.Height - 3));
12
13 font.Dispose();
14 brush.Dispose();
15
16 if (mark.ShowLine)
17 {
18 int nLineX = DrawArea.Left;
19
20 Pen pen = new Pen(mark.Color, 1);
21 pen.DashStyle = mark.LineStyle;
22
23 Graphics.DrawLine(pen, nLineX, fPosY, DrawArea.Right, fPosY);
24
25 pen.Dispose();
26 }
27 ...

Well by subtracing the size from fPosY of course it would be above the
line drawn at fPosY.

this should draw

Description
----------------

I think. Are you saying you want:

----------------
Description

If so it should be fPosY + the height of the line you drew + any margin.

The height returned from MeasureString will allow for characters with
different positioning on the text line. For example a P character will have
space below it, whereas a y will have space above it.

Is this the cause of the problem you have?
