使用asp.net转换为图像 [英] Convert to image using asp.net

问题描述

你好，

我需要代码来解决如何将富文本框/自由文本框内容（包含文本和图像）转换为图像文件并使用asp.net将其保存在本地系统中。请帮我把这个转发。

提前感谢...



示例代码：

 受保护  void  Button1_Click（ object  sender，EventArgs e）
 {
  string  Text = FreeTextBox1.Text; 
 Color FontColor = Color.Black; 
 Color BackColor = Color.SkyBlue; 
  string  FontName =   Times New Roman ; 
  int  FontSize =  14 ; 
  int 高度=  500 ; 
  int 宽度=  500 ; 
  string  FileName = txtFilename2save.Text; 
位图objBitmap = 新位图（宽度，高度）; 
 Graphics objGraphics = Graphics.FromImage（objBitmap）; 
 Color objColor; 
 Font objFont =  new 字体（FontName，FontSize）; 
 PointF objPoint =  new  PointF（5f，5f）; 
 SolidBrush objBrushForeColor =  new  SolidBrush（FontColor）; 
 SolidBrush objBrushBackColor =  new  SolidBrush（BackColor）; 
 objGraphics.FillRectangle（objBrushBackColor， 0 ， 0 ，宽度，高度）; 
 objGraphics.DrawString（Text，objFont，objBrushForeColor，objPoint）; 
  //   string From = ConfigurationManager.AppSettings [FromPath]。ToString（）;  
  //   string To = ConfigurationManager.AppSettings [ToPath]。ToString（）;  
  string  FromPath =  @  E：\\ \\ + FileName +  。GIF; 
  ///   string ToPath = @To + FileName +.JPG; 
  objBitmap.Save（FromPath，ImageFormat.Gif）; 
  //   Image1.ImageUrl =〜/ Questions / Original /+ FileName +.JPG;  
  string  mainImage =  @  E：\ + FileName +  。GIF; 
  //   ImageSetting（txtwatermark.Text，，mainImage）;  
 Image1.ImageUrl =  〜/ Image / + FileName +   _ new +  。GIF ; 
  //   convert2image（）;  
} 
 
  public   void  convert2image（）
 {
位图bit1 =  new 位图（ 200 ， 300 ，System.Drawing.Imaging .PixelFormat.Format64bppArgb）; 
图形gph1 = Graphics.FromImage（bit1）; 
  string  text; 
 gph1.Clear（Color.Orange）; 
 text = FreeTextBox1.Text; 
 gph1.DrawString（text， new 字体（  Arial， 12 ，FontStyle.Bold），
  new  SolidBrush （Color.SkyBlue）， new  PointF（ 0  .4F， 2  .4F））; 
 Response.ContentType =   image / Jpeg; 
 bit1.Save（Response.OutputStream，ImageFormat.Jpeg）; 
 bit1.Dispose（）; 
}
