flex+php在线拍照一[51空间]_PHP教程

flex+php在线拍照

昨天用flex+php做了一个在线拍照的小东东，可以实现会员头像的实时在线拍照更新。
首先来讲一讲原理：
1、将camera的内容显示在video中，这个不懂的参考actionscript的手册，里面有详细的讲解以及代码，
2、定义一下BitmapData对象，
m_pictureBitmapData = new BitmapData(DEFAULT_CAMERA_WIDTH,DEFAULT_CAMERA_HEIGHT);
然后将video的内容写进BitmapData对象里， m_pictureBitmapData.draw(video,new Matrix());
3、从左到右，从上到下，一个像素一个像素的读取BitmapData的rgb值，所有的rgb值用","分开，写进一个字符串里，
for(var i:int = 0; i < DEFAULT_CAMERA_WIDTH; i++)
{
for(var j:int = 0; j < DEFAULT_CAMERA_HEIGHT; j++)
{
if(m_pictureData.length > 0)
{
m_pictureData += "," + m_pictureBitmapData.getPixel(i,j).toString();
}
else
{
m_pictureData = m_pictureBitmapData.getPixel(i,j).toString();
}
}
}
service.getOperation("createjpeg").send(pic_width,pic_height,m_pictureData);//用amfphp进行保存
4、在服务端就把那些rgb值提取出来，一个像素一个像素的画点：
$img=imagecreatetruecolor($width,$height);
$m_tempPics=explode(',',$bitmap_data);
for ($i = 0; $i < $width; $i++)
{
for ($j = 0; $j < $height; $j++)
{
$pic_argb =(int) $m_tempPics[$i * $height + $j];
imagesetpixel($img,$i,$j,$pic_argb);
}
}
imagejpeg($img,"../../image/header/0.jpg");
imagedestroy($img);
return true;
5、详细的源码在附件里面，前面只是些重要提示代码。嗯，要懂得amfphp,还有flex。
还有什么不清楚的，

下面来看看 test.html文件

if ( hasProductInstall && !hasRequestedVersion ) {
// MMdoctitle is the stored document.title value used by the installation process to close the window that started the process
// This is necessary in order to close browser windows that are still utilizing the older version of the player after installation has completed
// DO NOT MODIFY THE FOLLOWING FOUR LINES
// Location visited after installation is complete if installation is required
var MMPlayerType = (isIE == true) ? "ActiveX" : "PlugIn";
var MMredirectURL = window.location;
document.title = document.title.slice(0, 47) + " - Flash Player Installation";
var MMdoctitle = document.title;

AC_FL_RunContent(
"src", "playerProductInstall",
"FlashVars", "MMredirectURL="+MMredirectURL+'&MMplayerType='+MMPlayerType+'&MMdoctitle="+MMdoctitle+"",
"width", "100%",
"height", "100%",
"align", "middle",
"id", "hphoto",
"quality", "high",
"bgcolor", "#869ca7",
"name", "hphoto",
"allowScriptAccess","sameDomain",
"type", "application/x-shockwave-flash",
"pluginspage", "http://www.adobe.com/go/getflashplayer"
);
} else if (hasRequestedVersion) {
// if we've detected an acceptable version
// embed the Flash Content SWF when all tests are passed
AC_FL_RunContent(
"src", "hphoto",
"width", "100%",
"height", "100%",
"align", "middle",
"id", "hphoto",
"quality", "high",
"bgcolor", "#869ca7",
"name", "hphoto",
"flashvars",'historyUrl=history.htm%3F&lconid=' + lc_id + '',
"allowScriptAccess","sameDomain",
"type", "application/x-shockwave-flash",
"pluginspage", "http://www.adobe.com/go/getflashplayer"
);
} else { // flash is too old or we can't detect the plugin
var alternateContent = 'Alternate HTML content should be placed here. '
+ 'This content requires the Adobe Flash Player. '
+ 'Get Flash';
document.write(alternateContent); // insert non-flash content
}
// -->
