One 、 stay XX Find a picture or yourself on PS And define it as skin

1.1 copy Picture to uires\image My name here is flag.png

1.2 uires Add below

<IMG>
    <file name="flag" path="image\flag.png"/>
</IMG>

1.3 skin.xml Define a skin   

<imglist name="skin_flag" src="img:flag" states="2"/>

1.4 Give... In the defined template img Specify this skin

<?xml version="1.0" encoding="utf-8"?>
<template>  
  <mine>
    <window skin="mine_bkskin" size="26,26" columnWeight="1" rowWeight="1">
      <img name="flag" pos="|,|" skin="skin_flag" show="0" offset="-0.5,-0.5" size="-1,-1"/>
      <text name="minecount" pos="|,|" show="0" offset="-0.5,-0.5" size="-1,-1" text="1"/>
    </window>
  </mine>
</template>

Two 、 Add processing functions
