cam faces

[Ev. rodrigo dos santos]

Personal who can help to extract something good, I changed the example code to simplify the mapping of the face,

 which I intend to perform is a type of facial recognition.....

//Init global variables.

var width = 320;

var height = 240;

var tLast = new Date();

//Called when application is started.

function OnStart()

{   

//Fix orientation to landscape since

//most phones cameras work this way.   

app.SetOrientation( "Landscape" );

 

//Stop screen turning off.

    app.PreventScreenLock( true );

    

//Create frame layout that fills the screen.

lay = app.CreateLayout( "Frame", "Horizontal,FillXY" );

   

//Create camera view control.

//(Reduce to QVGA-widthxheight resolution for performance reasons)

cam = app.CreateCameraView( 1, 1, "QVGA,UseBitmap,NoRotate,Front" );

cam.SetOnReady( cam_OnReady );

lay.AddChild( cam );  

    //Create an image control over the top of the 

//camera view with transparency (alpha).

img = app.CreateImage( null, 1, 1 );  

img.SetAlpha( 0.5 );  

lay.AddChild( img );     

img.SetPaintColor( "#ff0000"  );

img.SetPaintStyle( "Line" );

img.SetLineWidth( 2 );

img.SetTextSize( 16 );

img.SetAutoUpdate( false );

//Add main layout to app.

app.AddLayout( lay );

}

//Called when camera is ready.

function cam_OnReady()

{

//Start preview.

cam.StartPreview();

//Start image processing.

ProcessImage();

}

//Extract and process image data.

function ProcessImage()

{

    //Get faces list.

    var faces = cam.FindFaces( 10 ); 

    

    //Mark found faces over camera preview.

    DrawFaces( faces );

    

    //Call this function again ASAP.

    setTimeout( ProcessImage, 0 );

}

        

//Draw area where face detected.

function DrawFaces( faces )

{

    var corners, i, j, len;

    

    //Clear image.

    img.Clear();

    

    //Loop through faces list.

    for( i=0; i < faces.length; i++ )

    {

        //Get face info.

        var face = faces[i];

        

        //Mark face boundaries.      

           // img.DrawRectangle( face.midPoint.x/width - face.eyeDistance/width, 

           // face.midPoint.y/height - face.eyeDistance/height, 

            //face.midPoint.x/width + face.eyeDistance/width, 

            //face.midPoint.y/height + face.eyeDistance/height );

    

            //img.SetPaintStyle("Fill"); //Set style of objects drawn to 'Fill'.

 

    img.SetPaintColor("#ff4ee444"); //Set colour of objects drawn to 'Gray'.

    //img.DrawCircle(face.midPoint.x/width ,face.midPoint.y/width ,0.05);

    //img.DrawCircle(face.midPoint.x/width ,face.midPoint.x/width ,0.05);

    img.DrawArc(face.midPoint.x/width ,0.20,face.midPoint.y/height,0.35,0,360);

    img.DrawArc(face.midPoint.x/width ,0.20,face.midPoint.x/height,0.35,0,360);

       

    img.DrawImage("Img/arosto.png",face.midPoint.x/width ,face.midPoint.y/height,1,1);

    

    

    img.DrawLine(face.midPoint.x/width + face.eyeDistance/width, face.midPoint.y/height - face.eyeDistance/height, //cima ^

                 face.midPoint.x/width - face.eyeDistance/width, face.midPoint.y/height - face.eyeDistance/height);

                 face.midPoint.x/width + face.eyeDistance/width, face.midPoint.y/height - face.eyeDistance/height);//esquerda <

    img.DrawLine(face.midPoint.x/width - face.eyeDistance/width, face.midPoint.y/height + face.eyeDistance/height, 

                 face.midPoint.x/width + face.eyeDistance/width, face.midPoint.y/height + face.eyeDistance/height);//baixo v

    

    img.DrawLine(face.midPoint.x/width - face.eyeDistance/width, face.midPoint.y/height - face.eyeDistance/height,

//Pattern : (x1,y1,x2,y2,StartAngle,EndAngle).

            //face.midPoint.x/width + face.eyeDistance/width,

        var a =face.midPoint.x/width;  

        var b =face.midPoint.y/width;  

    img.SetPaintColor("#ff444444"); //Set colour of objects drawn to 'Red'.

    

    //Draw an arc.

    //Pattern : (x1,y1,x2,y2,StartAngle,EndAngle).

    //Draw frame rate.

I wanted to know why the drawe image ("Img / pic.png"); Does not work in this example I wanted to replace the circle with an image
