Hi Partha Mandayam,
Thank you for quick reply.

Step 1. Get ready to convert text into image using C#.Net.....!

Step 2. Add following two namespaces in your C#.Net project.

 

Step 3. Declare some variables to set the properties for your required image.

 

 

Step 4. Create a Bitmap object using Height and Width properties defined earlier.

 

 

Step 5. Create a Graphics object using this Bitmap object.

 

 

Step 6. Create Color, Font, and  PointF objects.

 

 

Step 7. Create two SolidBrush type objects.

 

 

 

 

 

 

Step 8. Draw rectangle using Graphics object and fill it with BackColor.

 

 

 

Step 9. Draw Text string on the specified rectangle using Graphics object.

 

 

 

Step 10. Save the image on your hard drive in the specified format.

 

 

Convert Text to Image in C# ::

using System.Drawing;
using System.Drawing.Imaging;

string FontName = "Courier New";
Color FontColor = Color.Black;
Color BackColor = Color.White;
int FontSize = 14;
int Width = 25;

//fontsize times 1.5 is just high enough
//to encase the text without spacer above or below.
float h = (FontSize * 1.5f);
int Height = int.Parse(h.ToString());

//file to save as
string FileName = "MyImage";

//fore color
SolidBrush objBrushForeColor = new SolidBrush(FontColor);

//back color
SolidBrush objBrushBackColor = new SolidBrush(BackColor);

//the point to start the text. I chose horizontal value of zero
//vertical starts at 2 pixels down.
Point objPoint = new Point(0,2);

//font object
Font objFont = new Font(FontName, FontSize);

//bitmap object
Bitmap objBitmap = new Bitmap(Width, Height);

//graphics object
Graphics objGraphics =
System.Drawing.Graphics.FromImage(objBitmap);

//the following line is not needed, but is shown
//in the vb example.. dont know why.
//Color objColor;

//draw a white rectangle
objGraphics.FillRectangle(objBrushBackColor, 0, 0, Width,
(FontSize*1.5f));

//draw the text
objGraphics.DrawString(character.ToString(), objFont, objBrushForeColor,
objPoint);

//save the bitmap.
objBitmap.Save(FileName + ".bmp", ImageFormat.Bmp);

The following code example is designed for use with Windows Forms, and it requires http://msdn.microsoft.com/en-us/library/system.windows.forms.painteventargs.aspxe, which is a parameter of the http://msdn.microsoft.com/en-us/library/system.windows.forms.control.paint.aspx event handler. The code performs the following actions:

·         Creates a text string to draw.

·         Defines the font as Arial (16pt).

·         Creates a solid, black brush to draw with.

·         Creates the coordinates of a point for the upper-left corner at which to draw the text.

·         Sets the format of the string to draw vertically

·         Draws the string to the screen using the font, brush, destination point, and format.

VB.NET Example:-

Public Sub DrawStringFloatFormat(ByVal e As PaintEventArgs)

 

    ' Create string to draw.

    Dim drawString As [String] = "Sample Text"

 

    ' Create font and brush.

    Dim drawFont As New Font("Arial", 16)

    Dim drawBrush As New SolidBrush(Color.Black)

 

    ' Create point for upper-left corner of drawing.

    Dim x As Single = 150.0F

    Dim y As Single = 50.0F

 

    ' Set format of string.

    Dim drawFormat As New StringFormat

    drawFormat.FormatFlags = StringFormatFlags.DirectionVertical

 

    ' Draw string to screen.

    e.Graphics.DrawString(drawString, drawFont, drawBrush, _

    x, y, drawFormat)

End Sub

 

C#.NET Example:-

public void DrawStringFloatFormat(PaintEventArgs e)

{

 

    // Create string to draw.

    String drawString = "Sample Text";

 

    // Create font and brush.

    Font drawFont = new Font("Arial", 16);

    SolidBrush drawBrush = new SolidBrush(Color.Black);

 

    // Create point for upper-left corner of drawing.

    float x = 150.0F;

    float y =  50.0F;

 

    // Set format of string.

    StringFormat drawFormat = new StringFormat();

    drawFormat.FormatFlags = StringFormatFlags.DirectionVertical;

 

    // Draw string to screen.

    e.Graphics.DrawString(drawString, drawFont, drawBrush, x, y, drawFormat);

}
