"code" : "hfuiew89", 
"type" : "location", 
"coordinates" : [ { "lat" : 40.9861, "lon" : 29.1046, "index" : 1 },

          { "lat" : 40.9809, "lon" : 29.2194, "index" : 3 }]

我正在使用jpeg编码器脚本.在脚本示例中,影片剪辑将转换为jpeg.不同,我想转换舞台,但只有一部分,如x:320-500,y:0-600.可能吗？

    jpgSource.draw(m);

    var jpgEncoder:JPGEncoder = new JPGEncoder(quality);
    var jpgStream:ByteArray = jpgEncoder.encode(jpgSource);     
    ...
}

create(partOfStage,90,"name");
