  Remove background color from Graphics.Clear()

  Apr 04, 2016 08:30 AM|imteyazahmad86|LINK

  HI all,

  I have a code to resize image. it works good just one thing that I dont want. 

   Bitmap bmPhoto = new Bitmap(Width, Height,
                                PixelFormat.Format24bppRgb);
              bmPhoto.SetResolution(fullSizeImg.HorizontalResolution,
                               fullSizeImg.VerticalResolution);
  
              Graphics grPhoto = Graphics.FromImage(bmPhoto);
              grPhoto.Clear(Color.Red);
              grPhoto.InterpolationMode = InterpolationMode.Default;
              grPhoto.CompositingQuality = CompositingQuality.HighQuality;
              grPhoto.SmoothingMode = SmoothingMode.HighQuality;
  
              grPhoto.DrawImage(fullSizeImg,
                  new Rectangle(destX, destY, destWidth, destHeight),
                  new Rectangle(sourceX, sourceY, sourceWidth, sourceHeight),
                  GraphicsUnit.Pixel);
  
              grPhoto.Dispose();

  In my bold section, it fills a Red color on outside of image. I dont want that red color. If I remove that line, it fills with black color. I dont want that color at all. I want it fits whatever empty spaces it is getting that filled with color.
