Text Alignment

Question

Hi,

  How to align string to Left, Right, Center and Middle?  I have done other alignment like middle center,middle left,middle right, top left etc using StringAligment. 

Help me to alignment string in Left, Right, Center and Middle.

StringFormat objStringFormat = new StringFormat();

 objStringFormat.Alignment = StringAlignment.Center;

 objStringFormat.LineAlignment = StringAlignment.Center;

Thank You

Hi,

I'm not sure what do you mean . 
Could you please be more clear?
what's the difference between
 Left, Right, Center and Middle
and middle center,middle left,middle right, top left?

Hi,
 
   Please look at the link below,

http://www.kodakgallery.com/gallery/creativeapps/slideShow/Main.jsp?token=994539887113%3A1776755655&cm_mmc=site_email-_-new_site_share-_-core-_-View_photos_button

  
In the figure,
I have drawn text content as Alignment name. filled circle in Cyan color represent my insertion point specified for drawing string

BottomLeft Alignment is different from Left,
BottomRight Alignment is different from Right ,
BottomCenter Alignment is different from Center
MiddleCenter Alignment  is different from middle.

You can watch the different when observed closely. In Left,Right,Center and Middle Alignment Insertion point will touch the text,but in BottomLeft,BottomRight,BottomCenter and MiddleCenter,Inssertion point will not touch the text.


I have attached code for refer:

StringFormat  objStringFormat = new StringFormat();

           if (Justification == "Top Left")

           {

               objStringFormat.Alignment = StringAlignment.Near;

               objStringFormat.LineAlignment = StringAlignment.Near;

 

           }

           else if (Justification == "Top Center")

           {

               objStringFormat.Alignment = StringAlignment.Center;

               objStringFormat.LineAlignment = StringAlignment.Near;

 

           }

           else if (Justification == "Top Right")

           {

               objStringFormat.Alignment = StringAlignment.Far;

               objStringFormat.LineAlignment = StringAlignment.Near;

 

           }

           else if (Justification == "Middle Left")

           {

               objStringFormat.Alignment = StringAlignment.Near;

               objStringFormat.LineAlignment = StringAlignment.Center;

 

           }

           else if (Justification == "Middle Center")

           {

               objStringFormat.Alignment = StringAlignment.Center;

               objStringFormat.LineAlignment = StringAlignment.Center;

 

           }

           else if (Justification == "Middle Right")

           {

               objStringFormat.Alignment = StringAlignment.Far;

               objStringFormat.LineAlignment = StringAlignment.Center;

 

           }

           else if (Justification == "Bottom Left")

           {

               objStringFormat.Alignment = StringAlignment.Near;

               objStringFormat.LineAlignment = StringAlignment.Far;

 

           }

           else if (Justification == "Bottom Center")

           {

               objStringFormat.Alignment = StringAlignment.Center;

               objStringFormat.LineAlignment = StringAlignment.Far;

 

           }

           else if (Justification == "Bottom Right")

           {

               objStringFormat.Alignment = StringAlignment.Far;

               objStringFormat.LineAlignment = StringAlignment.Far;

           }

 

Graphics g=this.CreateGraphics();

GraphicsPath m_Path=new GraphicsPath();

m_Path.AddString(m_Content, m_FontFamily, m_Font.Style, m_Font.Size, m_InsertionPointF,objStringFormat);

g.DrawPath(m_Pen, m_Path);

In the link below given 18 different Text Alignment possible.And we can align to a point, or to a bounding rect

Hello,

You have to set two things,

1) StringAlignment   (Specifies the alignment of a text string relative to its layout rectangle. It can be any from these three Near,Far and Center)

2)  LineAlignment  (Gets or sets the line alignment on the horizontal plane.)

See the bellow example,

NOTE :
When used with the LineAlignment property, this enumeration sets the vertical alignment for a drawn string. When used with the Alignment property, this enumeration sets the horizontal alignment.

private void ShowLineAndAlignment(PaintEventArgs e)
{

    // Construct a new Rectangle .
    Rectangle  displayRectangle = 
        new Rectangle (new Point(40, 40), new Size (80, 80));

    // Construct 2 new StringFormat objects
    StringFormat format1 = new StringFormat(StringFormatFlags.NoClip);
    StringFormat format2 = new StringFormat(format1);

    // Set the LineAlignment and Alignment properties for
    // both StringFormat objects to different values.
    format1.LineAlignment = StringAlignment.Near;
    format1.Alignment = StringAlignment.Center;
    format2.LineAlignment = StringAlignment.Center;
    format2.Alignment = StringAlignment.Far;

    // Draw the bounding rectangle and a string for each
    // StringFormat object.
    e.Graphics.DrawRectangle(Pens.Black, displayRectangle);
    e.Graphics.DrawString("Showing Format1", this.Font, 
        Brushes.Red, (RectangleF)displayRectangle, format1);
    e.Graphics.DrawString("Showing Format2", this.Font, 
        Brushes.Red, (RectangleF)displayRectangle, format2);
}

What Benita Blas is suggesting will work, but is a lot of code to achieve something so simple. An alternative to this would be to do something like this.

Create an enumeration of all the possible text alignments. the enumeration makes it much easier to specify how you want the text positioned, with names that have a clean and understandable meaning.

        public enum TextAlignment
        {
            TopLeft = System.Drawing.StringAlignment.Near << 2 | System.Drawing.StringAlignment.Near,
            TopCenter = System.Drawing.StringAlignment.Near << 2 | System.Drawing.StringAlignment.Center,
            TopRight = System.Drawing.StringAlignment.Near << 2 | System.Drawing.StringAlignment.Far,
            MiddleLeft = System.Drawing.StringAlignment.Center << 2 | System.Drawing.StringAlignment.Near,
            MiddleCenter = System.Drawing.StringAlignment.Center << 2 | System.Drawing.StringAlignment.Center,
            MiddleRight = System.Drawing.StringAlignment.Center << 2 | System.Drawing.StringAlignment.Far,
            BottomLeft = System.Drawing.StringAlignment.Far << 2 | System.Drawing.StringAlignment.Near,
            BottomCenter = System.Drawing.StringAlignment.Far << 2 | System.Drawing.StringAlignment.Center,
            BottomRight = System.Drawing.StringAlignment.Far << 2 | System.Drawing.StringAlignment.Far
        }

next create a helper method that will take a StringFormat object and the desired text alignment. (this is not a requirement but will help make the code more re-useable)

        public static void SetTextAlignment(System.Drawing.StringFormat format, TextAlignment alignment)
        {
            var shift = ((int)alignment) >> 2;
            var mod = ((int)alignment) % 4;

            format.Alignment = (System.Drawing.StringAlignment)mod;
            format.LineAlignment = (System.Drawing.StringAlignment)shift;
        }

With these two things you can now modify Benita Blas code to look something like this.

            System.Drawing.StringFormat objStringFormat = new System.Drawing.StringFormat();
            SetTextAlignment(objStringFormat, TextAlignment.TopLeft);
            System.Drawing.Graphics g = this.CreateGraphics();
            System.Drawing.Drawing2D.GraphicsPath m_Path = new System.Drawing.Drawing2D.GraphicsPath();
            m_Path.AddString(m_Content, m_FontFamily, m_Font.Style, m_Font.Size, m_InsertionPointF, objStringFormat);
            g.DrawPath(m_Pen, m_Path);

In addition to reducing the amount of code that is needed, this should also help make the code more readable and maintainable.

Nice though this is I suspect that two years after the question it's kind of irrelevant to the OP. :)
