推荐答案

下面的分步代码将文本转换为图像并将其显示在网页上. br/>
第0步-包括命名空间
使用System.Drawing;
使用System.Drawing.Imaging;

第1步-声明属性
声明一些变量，这些变量将控制图像的行为和颜色.

字符串Text = Request.QueryString ["Text"];
颜色FontColor = Color.Blue;
彩色BackColor = Color.White;
字符串FontName ="Times New Roman";
int FontSize = 10;
int高度= 150;
int宽度= 150;

第2步-创建位图对象以保存图像
位图位图=新位图(宽度，高度);

第3步-使用此Bitmap对象创建一个Graphics对象
图形graphics = Graphics.FromImage(bitmap);

第4步-创建Color，Font和PointF对象.
颜色color = Color.Gray; ;
字体font = new Font(FontName，FontSize);
//定义文本将在图像的指定区域中显示的位置
PointF point =新的PointF(5.0F，5.0F);

第5步-创建画笔和笔
SolidBrush BrushForeColor =新的SolidBrush(FontColor);
SolidBrush BrushBackColor =新的SolidBrush(BackColor);
笔边框笔=新笔(彩色);

第6步-使用图形"对象绘制矩形
矩形displayRectangle =新Rectangle(新Point(0，0)，新Size(宽度-1，高度-1));
graphics.FillRectangle(BrushBackColor，displayRectangle);
graphics.DrawRectangle(BorderPen，displayRectangle);

第7步-使用Graphics对象在指定的矩形上绘制文本字符串
//定义字符串格式
StringFormat format1 =新的StringFormat(StringFormatFlags.NoClip);
StringFormat format2 =新的StringFormat(format1);
//使用文本格式绘制文本字符串
graphics.DrawString(文本，字体，Brushes.Red，(RectangleF)displayRectangle，format2);

第8步-将位图以JPEG格式发送到页面输出流
Response.ContentType ="image/jpeg";
bitmap.Save(Response.OutputStream，ImageFormat.Jpeg);

The below step by step code converts the text into image and displays it onto the web page.

Step 0 - Include Namespaces
using System.Drawing;
using System.Drawing.Imaging;

Step 1 - Declare Properties
Declare some variables that will control the behavior and color of the image.

string Text = Request.QueryString["Text"];
Color FontColor = Color.Blue;
Color BackColor = Color.White;
String FontName = "Times New Roman";
int FontSize = 10;
int Height = 150;
int Width = 150;

Step 2 - Create a Bitmap Object to Hold The Image
Bitmap bitmap = new Bitmap(Width, Height);

Step 3 - Create a Graphics object using this Bitmap object
Graphics graphics = Graphics.FromImage(bitmap);

Step 4 - Create Color, Font, and PointF objects.
Color color = Color.Gray; ;
Font font = new Font(FontName, FontSize);
//define where the text will be displayed in the specified area of the image
PointF point = new PointF(5.0F, 5.0F);

Step 5 - Create Brushes and Pen
SolidBrush BrushForeColor = new SolidBrush(FontColor);
SolidBrush BrushBackColor = new SolidBrush(BackColor);
Pen BorderPen = new Pen(color);

Step 6 - Draw Rectangle using Graphics object
Rectangle displayRectangle = new Rectangle(new Point(0, 0), new Size(Width - 1, Height - 1));
graphics.FillRectangle(BrushBackColor, displayRectangle);
graphics.DrawRectangle(BorderPen, displayRectangle);

Step 7 - Draw Text string on the specified rectangle using Graphics object
//Define string format
StringFormat format1 = new StringFormat(StringFormatFlags.NoClip);
StringFormat format2 = new StringFormat(format1);
//Draw text string using the text format
graphics.DrawString(Text, font, Brushes.Red, (RectangleF)displayRectangle, format2);

Step 8 - Send the bitmap to page output stream in JPEG format
Response.ContentType = "image/jpeg";
bitmap.Save(Response.OutputStream, ImageFormat.Jpeg);
