Mapxtreme for Java中添加自定義圖示

MapXtreme Java提供的圖示很少，做出的地圖看起來不美觀。MapXtreme Java中自定義符号

我目前想用這種方法：

将自定義的符号*.bmp儲存到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 中使用該符号，要首先将該bmp格式的圖示轉換為gif格式，然後放在程式目錄中并寫在屬性檔案裡

取出圖的檔案名

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