C # automatically generate beautiful crystal effect portraits

Similar to other Weibo systems,

However, the avatar of "more intranets and microblogs" can be more beautiful, because the system achieves the crystal effect.
C # The program implements the crystal effect Avatar process:

(1) scale down an image to a portrait with a width or height of 90;

(2) The user selects a suitable position to crop the final portrait of 90x90;

(3) Add the crystal effect;
