StringFormatFlags Enum

Definition

Namespace:

System.Drawing

Assembly:

System.Drawing.Common.dll

Source:

StringFormatFlags.cs

Specifies the display and layout information for text strings.

This enumeration supports a bitwise combination of its member values.

Fields

Name	Value	Description
DirectionRightToLeft	1	Text is displayed from right to left.
DirectionVertical	2	Text is vertically aligned.
FitBlackBox	4	Parts of characters are allowed to overhang the string's layout rectangle. By default, characters are repositioned to avoid any overhang.
DisplayFormatControl	32	Control characters such as the left-to-right mark are shown in the output with a representative glyph.
NoFontFallback	1024	Fallback to alternate fonts for characters not supported in the requested font is disabled. Any missing characters are displayed with the fonts missing glyph, usually an open square.
MeasureTrailingSpaces	2048	Includes the trailing space at the end of each line. By default the boundary rectangle returned by the MeasureString method excludes the space at the end of each line. Set this flag to include that space in measurement.
NoWrap	4096	Text wrapping between lines when formatting within a rectangle is disabled. This flag is implied when a point is passed instead of a rectangle, or when the specified rectangle has a zero line length.
LineLimit	8192	Only entire lines are laid out in the formatting rectangle. By default layout continues until the end of the text, or until no more lines are visible as a result of clipping, whichever comes first. Note that the default settings allow the last line to be partially obscured by a formatting rectangle that is not a whole multiple of the line height. To ensure that only whole lines are seen, specify this value and be careful to provide a formatting rectangle at least as tall as the height of one line.
NoClip	16384	Overhanging parts of glyphs, and unwrapped text reaching outside the formatting rectangle are allowed to show. By default all text and glyph parts reaching outside the formatting rectangle are clipped.

Examples

The following code example demonstrates the following members:

• Rectangle

• StringFormat

• StringFormat

• Alignment

• LineAlignment

• StringAlignment

• StringFormatFlags

This example is designed to be used with Windows Forms. Paste the code into a form and call the ShowLineAndAlignment method when handling the form's Paint event, passing e as PaintEventArgs.

private:
   void ShowLineAndAlignment( PaintEventArgs^ e )
   {
      // Construct a new Rectangle .
      Rectangle displayRectangle = Rectangle(Point(40,40),System::Drawing::Size( 80, 80 ));
      
      // Construct 2 new StringFormat objects
      StringFormat^ format1 = gcnew StringFormat( StringFormatFlags::NoClip );
      StringFormat^ format2 = gcnew 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, displayRectangle, format1 );
      e->Graphics->DrawString( "Showing Format2", this->Font, Brushes::Red, displayRectangle, format2 );
   }

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);
}

Private Sub ShowLineAndAlignment(ByVal e As PaintEventArgs)

    ' Construct a new Rectangle.
    Dim displayRectangle _
        As New Rectangle(New Point(40, 40), New Size(80, 80))

    ' Construct two new StringFormat objects
    Dim format1 As New StringFormat(StringFormatFlags.NoClip)
    Dim format2 As 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", Me.Font, Brushes.Red, _
        RectangleF.op_Implicit(displayRectangle), format1)
    e.Graphics.DrawString("Showing Format2", Me.Font, Brushes.Red, _
        RectangleF.op_Implicit(displayRectangle), format2)
End Sub

Remarks

StringFormatFlags is used by the StringFormat class.

Note

The FitBlackBox field was misnamed and its behavior is similar to the NoFitBlackBox field in the original GDI+ implementation.
