Synergist

Hi Michael,

I'm one of the guys that work on the Bookvar.net project that you blogged a while ago on your blog. Your sample idea is great and I'm willing to help you on the math side. Currently I'm working on a commercial project that does some thing quite similar to this and I got it zoom correctly so I'm pretty sure I can help. Later today I'll look at your sample and send you back some suggestions on how to solve the problem.

Greetings,

Deyan

Will a recording of this webinar be made available?  Are past webinars available for viewing?  (Perhaps an opportunity for a Silverlight application.. ;)  Thanks,

Any chance you can do your Webinar in SL 1.1(2.0) with C#?

Hi Michael,

today, when I was in the pete blog (http://community.irritatedvowel.com/blogs/pete_browns_blog/default.aspx), I've seen a picture of your application, really nice, good work ;)

as I see this application is published about 23 days, but I can't see any comment about your calling for math help (maybe you corrected that or someone sent an e-mail to you), but let me to post myself correction :

Synergist.Magnifier.prototype._UpdateTranslation = function()

{

   ///<summary>Update the translation of the VideoBrush to reflect the magnification and position of the magnifying glass</summary>

   if (this.MediaElement.NaturalVideoHeight == 0)

   {

       return;

   }

   // the position of the magnifier

   var left = this.Canvas["Canvas.Left"];// + this.Canvas.Width / 2;

   var top = this.Canvas["Canvas.Top"];// + this.Canvas.Height / 2;

   var mediaLeft = this.MediaElement["Canvas.Left"];

   var mediaTop = this.MediaElement["Canvas.Top"];

   var halfWidth = this.Canvas.Width * 0.5;

   var halfScaledWidth = halfWidth * this.BrushScale.ScaleX;

   var offsetX = left - mediaLeft;

   var offsetY = top - mediaTop;

   var naturalAspect = this.MediaElement.NaturalVideoWidth / this.MediaElement.NaturalVideoHeight;

var videoAspect = this.MediaElement.Width / this.MediaElement.Height;

var topMargin = 0;

var leftMargin = 0;

if (naturalAspect > videoAspect)

{

   var visibleHeight = this.MediaElement.Width / naturalAspect;

   topMargin = this.BrushScale.ScaleX *(this.MediaElement.Height - visibleHeight) / 2;

}

else

{

   var visibleWidth = this.MediaElement.Height / naturalAspect;

   leftMargin = this.BrushScale.ScaleX * (this.MediaElement.Width - visibleWidth) / 2;

}

   this.BrushTranslation.X = mediaLeft+leftMargin-(offsetX *this.BrushScale.ScaleX)- (this.Canvas.Width*this.BrushScale.ScaleX) / 2;

   this.BrushTranslation.Y = mediaTop+topMargin-(offsetY *this.BrushScale.ScaleX)- (this.Canvas.Height*this.BrushScale.ScaleX)/ 2;

   window.status = mediaLeft+'|'+scaleOffsetX+'|'+offsetY+'|'+this.BrushScale.ScaleX.toString();

}
