MeteoInfo Java版二次开发教程十一

ycjtj1dx202ly

此次教程实现MICAPS第13类数据卫星云图文件的读取和显示，MICAPS云图数据通常是Lambert投影，在添加云图RasterLayer之前要把MapView投影为云图的投影。代码里面用到了调色板文件来设置云图显示图例。具体代码如下：

考了程序之后显示：
File "<iostream>", line 1
    private void TSMI_MICAPS13_Click(object sender, EventArgs e)
    ^
SyntaxError: mismatched input '           ' expecting EOF

有没有代码，我现在按照这个教程来处理，显示等值线不出来啊。
