(原创)JSP+FLASH实现大头帖，可以存储图片

以前发过一个抓图的，没有实现存储，这次给完成，主要就下面些

Flash部分：因为以前发过，这次就主要发传数据的部分，看不懂得可以去搜Flash视频+抓图

//传值
var send_lv:LoadVars=new LoadVars();
var load_lv:LoadVars=new LoadVars();

load_lv.onLoad=function(success) {
trace("ok");
}
//////////////////////抓图///////////////////
import flash.display.BitmapData;
var pixData:String="";

photo_btn.onRelease=function(){
var WIDTH:Number=my_video.width;
var HEIGHT:Number=my_video.height;
timer=getTimer();
var bd:BitmapData=new BitmapData(WIDTH/2.5,HEIGHT/2.5,false,0x00CCCCCC);
bd.draw(my_video);
var tempObj:MovieClip = _root.createEmptyMovieClip("tempObj", 100);
tempObj._x = 50;
tempObj._y = 25;

tempObj.attachBitmap(bd, 1, "always", true);
var space:Array=new Array("cao","00000","0000","000","00","0");
for(var i=0;i<160;i++) {
for(var j=0;j<120;j++) {
pixInfo=bd.getPixel(i,j).toString(16);
if(pixInfo.length<6){
pixInfo=space[pixInfo.length]+pixInfo;
}//endif

pixData+=pixInfo+",";//String.fromCharCode(pixInfo)+",";
}//endfor1
}//endfor2
trace(pixData.length);
}
save_btn.onRelease=function(){
send_lv.pixData=pixData;
send_lv.sendAndLoad("http://127.0.0.1:8080/test/ProcessPixServlet",load_lv,"POST");
}
