Posted in actionscript 3, flex 3 on March 15th, 2010 by admin – Comments Off

Hey I was searching in internet how to do a drag that create a exact copy of the image without loading it. All the examples were with Embed images so i needed some example that Image load bitmap and then do drag without having to load bitmap twice. So take a look:

// fire from MouseEvent.MOUSE_DOWN event
private function doDrag(e:MouseEvent):void {
    var dragInitiator:Image = e.currentTarget as Image;
    var dragSource:DragSource = new DragSource();
    dragSource.addData(_core, "core");
   
    var dragProxy:Image = new Image ();
    dragProxy.source = new Bitmap((dragInitiator.content as Bitmap).bitmapData);
   
    DragManager.doDrag(dragInitiator, dragSource, e, dragProxy);
}

equal function String.fromCharCode in PHP

Hey it was problem before I see this solution, to pass charactes to PHP like numbers, basicly because Flash use fromCharCode in UTF-8 format and PHP do chr function work in ASCII.

        return false; // bad first byte || out of range

    $arr = array(1 => 192, // byte position => range from

    foreach ($arr as $key => $val) {
        if ($n >= $val) { // add byte to the 'char' array
            $char[] = ord($ch{$key}) - 128;
            $range  = $val;
        } else {
            break; // save some e-trees
        }
    }

    $retval = ($n - $range) * pow(64, sizeof($char));

    foreach ($char as $key => $val) {
        $pow = sizeof($char) - ($key + 1); // invert key
        $retval += $val * pow(64, $pow);   // dark magic
    }

    return $retval;

Camera.getCamera problem => solution

Posted in actionscript 3, example on January 23rd, 2010 by admin – Comments Off

When you try to add a camera by name like this:

1
2
var cameraName:String = "WebCam";
var cam:Camera = Camera.getCamera(cameraName);

or like this

1
var cam:Camera = Camera.getCamera(cameranames[0]);

both return cam = null

Solution:

You need to add camera index like String in order to work

1
2
3
4
5
6
7
8
9
10
11
var cameraName:String = "WebCam";
var camera:Camera;
const imax:int = Camera.names.length;
var i:int = 0;
while (i < imax) {
    if (Camera.names[i] == cameraName) {
        camera = Camera.getCamera(String(i));
        break;
    }
    i++;
}

or use this function

1

12
13
const camera:Camera = getCamera("webCam");
       
private static function getCamera($cameraName_:String):Camera {
    const imax:int = Camera.names.length;
    var i:int = 0;
    while (i < imax) {
        if (Camera.names[i] == $camName_) {
            return Camera.getCamera(String(i));
        }
        i++;
    }
    return null;
}

so now you will have your camera that you wanted:

Flash video Player Snapshot

Posted in PHP, actionscript 3, projects & snippets on September 14th, 2009 by admin – Comments Off

Hi I have recently working on saving different format images from flash. My previous work on this script was: Image Encode with Flash and PHP. Here you can create snapshots from video source.

Example

In this example you can save exported images also in your computer. I like this example more, because you can get different images, not boring same image again.

Screenshots:
snapshot file 1
snapshot file 2
snapshot file 3
