  save image error in gdi

  Jan 28, 2011 01:29 PM|LINK

  Hi i am using this example http://efreedom.com/Question/1-1758762/Create-Image-Rounded-Corners-CSharp to round the corners of images, the problem i have is when i save the image because i need to overwite the exsiting image i am getting a GDI error.
  
  any ideas how i can fix this?
  
  string directory = Server.MapPath("/uploaded_assets/images/");
  string path = string.Format("{0}{1}", directory, selectedImageFile);
  
  System.Drawing.Image objImage = System.Drawing.Image.FromFile(path);//From File
  
              int CornerRadius = 10;
              Color BackgroundColor = Color.White;
  
              CornerRadius *= 2;
              Bitmap RoundedImage = new Bitmap(objImage.Width, objImage.Height);
              Graphics g = Graphics.FromImage(RoundedImage);
              g.Clear(BackgroundColor);
              g.SmoothingMode = SmoothingMode.AntiAlias;
              Brush brush = new TextureBrush(objImage);
              GraphicsPath gp = new GraphicsPath();
              gp.AddArc(0, 0, CornerRadius, CornerRadius, 180, 90);
              gp.AddArc(0 + RoundedImage.Width - CornerRadius, 0, CornerRadius, CornerRadius, 270, 90);
              gp.AddArc(0 + RoundedImage.Width - CornerRadius, 0 + RoundedImage.Height - CornerRadius, CornerRadius, CornerRadius, 0, 90);
              gp.AddArc(0, 0 + RoundedImage.Height - CornerRadius, CornerRadius, CornerRadius, 90, 90);
              g.FillPath(brush, gp);
              objImage.Dispose();
  
              RoundedImage.Save(path); //THIS IS WHERE THE ERROR OCCURS
  
  
  
  The stack trace is below the error occurs on  RoundedImage.Save(path)
  
  is this because i am editing the image then overwriting the same image?
  
  the path currently = "C:\development\cms\uploaded_assets\images\fd172f4a-86e8-44df-a8d1-c10e7c42acf8_orig.jpg"

  Seems u are trying to Update Your Image Without Releasing it from Edit Mode.
  
  means When u try to Save Image You U Still Using it.

  System.Drawing.Image objImage = System.Drawing.Image.FromFile(path);//From File
  
              int CornerRadius = int.Parse(ddlRoundCornersRadius.SelectedValue);
              Color BackgroundColor = Color.White;
  
              CornerRadius *= 2;
              Bitmap RoundedImage = new Bitmap(objImage.Width, objImage.Height);
              Graphics g = Graphics.FromImage(RoundedImage);
              g.Clear(BackgroundColor);
              g.SmoothingMode = SmoothingMode.AntiAlias;
              Brush brush = new TextureBrush(objImage);
              GraphicsPath gp = new GraphicsPath();
              gp.AddArc(0, 0, CornerRadius, CornerRadius, 180, 90);
              gp.AddArc(0 + RoundedImage.Width - CornerRadius, 0, CornerRadius, CornerRadius, 270, 90);
              gp.AddArc(0 + RoundedImage.Width - CornerRadius, 0 + RoundedImage.Height - CornerRadius, CornerRadius, CornerRadius, 0, 90);
              gp.AddArc(0, 0 + RoundedImage.Height - CornerRadius, CornerRadius, CornerRadius, 90, 90);
              g.FillPath(brush, gp);
              objImage.Dispose();
  
              RoundedImage.Save(path);
