void Page_Load(object sender, EventArgs e)
{
int intWidth = 0;
int intHeight = 0;
string FileName = null;
intWidth = 400;
intHeight = 200;
FileName = "MyImages/Images.png";
Bitmap objBitmap = new Bitmap(intWidth, intHeight);
Graphics objGraphic = Graphics.FromImage(objBitmap);
//*** Create Images ***//
objGraphic.FillRectangle(Brushes.Maroon, 0, 0, intWidth, intHeight);
//*** Write Text ***//
string strText = "The Matrix";
//*** String ***//
//*** Font **//
PrivateFontCollection myFont = new PrivateFontCollection();
myFont.AddFontFile(Server.MapPath("MyImages/MLTWNII_.ttf"));
FontFamily thisFont = myFont.Families[0];
Font objFont = new Font(thisFont, 30, FontStyle.Bold);
//*** Font Style ***//
SolidBrush objBrushWrite = new SolidBrush(Color.YellowGreen);
//*** Font Color ***//
//*** Text Align ***//
StringFormat strFormat = new StringFormat();
strFormat.Alignment = StringAlignment.Center;
//*** .Near (Left) , .Far (Right) ***//
strFormat.LineAlignment = StringAlignment.Center;
//*** .Near (Top) , .Far (Down) ***//
//*** DrawString ***//
objGraphic.DrawString(strText, objFont, objBrushWrite, new Rectangle(0, 0, intWidth, intHeight), strFormat);
//*** Save As ***//
objBitmap.Save(Server.MapPath(FileName), ImageFormat.Png);
//*** Close ***//
objGraphic.Dispose();
//*** Nothing ***//
objBitmap = null;
objGraphic = null;
//*** View Images ***//
this.imgPicture.ImageUrl = FileName;
