Mapxtreme for Java中添加自定义图标

MapXtreme Java提供的图标很少，做出的地图看起来不美观。MapXtreme Java中自定义符号
我目前想用这种方法：
将自定义的符号*.bmp保存到C:/Documents and Settings/Administrator/Application Data/MapInfo/MapInfo/Professional/700/CustSymb即可在pro中使用，如果要在xtreme for java 中使用该符号，要首先将该bmp格式的图标转换为gif格式，然后放在程序目录中并写在属性文件里

取出图的文件名

cximgurl=file:///d://cqyc//Jmap//images//XYCYJ.GIF
