Drawstring up to down textdirection right (like chinese old style)

Question

I want to print using Graphics.DrawString() method but I want to print that up to down.

For example I have string "Hello" and I want to be printed

H
e
l
l
o

With only one Graphics.DrawString()

Is it possible or not? because I have dynamic length of text.

Answer 1

Here is code to show Text vertically, not rotated. In the 1st panel the text is left aligned, in the 2nd & 3rd Panel it is centered. The Text to be shown is simply the Panel.Text and the Font is the Panel's font.

The 1st solution uses only one DrawString; it simply inserts linefeeds between all characters.

The 2nd Panel looks much nicer and you can specify a positive or negative leading but the code is a bit more involved - you get what you pay for.

(Except here on SO ;-)

private void panel1_Paint(object sender, PaintEventArgs e)
{
    string s = "";
    foreach(char c in panel1.Text) s += c.ToString() + "\r\n";
    e.Graphics.DrawString(s, panel1.Font, Brushes.Black, Point.Empty);
    SizeF sf = e.Graphics.MeasureString(s, panel1.Font);    //**
    panel1.Size = new Size((int)sf.Width, (int)sf.Height);  //**
}

private void panel2_Paint(object sender, PaintEventArgs e)
{
    float leading = -1.75f;  // <-- depends on font and taste
    float maxWidth = 0f;  //**
    Dictionary<char, Size> charSizes = new Dictionary<char, Size>();
    foreach (char c in panel2.Text)
        if (!charSizes.ContainsKey(c))
        {
            SizeF sf = e.Graphics.MeasureString(c.ToString(), panel2.Font);
            charSizes.Add(c, new Size((int)sf.Width, (int)sf.Height) );
            if (maxWidth < (int)sf.Width) maxWidth = (int)sf.Width;   //**
        }
    panel2.Width = (int)(maxWidth * 2);   // for panel size  //**
    float y = 0f;
    foreach (char c in panel2.Text)
    {
        e.Graphics.DrawString(c.ToString(), panel2.Font, Brushes.Black, 
                   new Point( ( panel2.Width - charSizes[c].Width) / 2, (int)y) );
        y += charSizes[c].Height + leading;
    }
    panel2.Height = (int)y;  //**
}

Edit: //** added code to resize the panels

Here is a screenshot; the middle panel has a leading of +2.75f the right one of +5f:
