MO中利用图片生成点符号专题　 deskfee 发表于 2005-3-15 14:34:24 用truetype字体可以比较方便的实现点符号，但用图片可以实现更加漂亮的点符号（如果你认为你做的图标足够漂亮的话，^_^），只是实现起来麻烦一点。 文件是txt,下载完后请先更改-MO use photographs to generate symbols deskfee topic published in 2005-3-15 14:34:24 truetype fonts can be used to facilitate the realization of more symbolic point, but pictures can be used to achieve a more beautiful symbol of the point (if you think you have done enough beautiful icon, ^ _ ^), but is only one point up trouble.
