C # automatic generation of beautiful crystal effect avatar implementation code

  This article mainly introduces the C # automatic generation of beautiful crystal effect avatar implementation code, a friend in need can refer to the

As with other micro-blogging systems, users in the "multi-Intranet microblogging system" can also upload their avatar and support avatar clipping.   But "multi-intranet micro-blogging system" can be more beautiful head, because the system to achieve the crystal effect of the head. C # program to achieve the crystal effect of the image of the process is:   (1) thumbnail to the width or height of =90 head,   (2) by the user to select the appropriate location to cut 90x90 final head;   (3) Add crystal Effect;   Code dedication:   The code is as follows:///<summary>///to draw the crystal effect of Avatar///</summary>///<param name= "Containspage" ></param>///< Param name= "W" ></param>///<param name= "h" ></param>///<param name= "memostring" ></ param> public static void Avatar (Page containspage, string filename, int r, int m, int s, int x, int y, bool save, Stri ng New_avatar) {System.Drawing.Image imagesrc = System.Drawing.Image.FromFile (HttpContext.Current.Server.MapPath ("/ ") + filename); int w = imagesrc.width; int h = imagesrc.height;   if (r = = 1 | | r = = 3) {h = imagesrc.width w = imagesrc.height}   if (save) {w = h = \ n]   if (w &G T ) W = 300; if (h >) h = 300;   Color BackColor = color.darkturquoise; Size size = new Size (w, h);   System.drawIng.
