Talking Trash – An overview of Player GC

Okay, so, I have been a little behind schedule actually posting content. Here is my first attempt at reconcilliation. These are the slides from my garbage collection talk at flash and the city this year. They go into moderate depth about the internals of garbage collection on the Flash Player and AIR along with some speculation about where things may be going. The speculation is based off of commits happening on the tamarin project from our friends at Adobe.

  Cheers, Labriola

At 360|Flex DC yesterday, I presented my “Whats under your skin” presentation, all about architecting components with skins and layouts. I had a great audience, who was very engaged and asked lots of pertinent questions.

For anyone interested, here are the slides. The code for the ShoppingList component can be found below from the download link. The code for the Clocks are proprietary, and can not be shared. Sorry. Download

Today, I presented my Flex 4 for Flex 3 developers presentation at FlashCamp Chicago. For those that wanted the slide deck, you can find it here. In this, I discuss a number of differences between flex 3 and flex 4, and what an existing Flex 3 developer will need to know to start being productive in Flex 4.

I woke up this morning…

and found the public beta of flash player 10 was out. How cool is that. I knew this would be coming before too long, but didnt realize that it would be out so quickly. This new version is filled with lots of new features aimed at allowing greater “expressiveness” in flash player content, such as 3d effects, custom filters, enhanced text rendering, and revs to the drawing API. Of course, like each version before it, FP10 also has lots of performance enhancements. What are you waiting for go get it on adobe labs I’m particularly looking forward to working with the Advanced Text Rendering features, which promise to allow lots of layout possibilities, including bi-directional text! more later

Hey, what am I doing on blogs.digitalprimates.net?

I've been a bit slow in getting this announcement out, as I see several other bloggers have already posted on this, but the rumors are true.  Tapper, Nimer and Associates. Inc. has teamed up with Digital Primates Inc.    Some of you may recall, it was just over a year ago that I teamed up with Mike Nimer to form Tapper, Nimer and Associates.  It's quite an odd experience for me to go from a solo propietorship to a team of 15 or so developers in about 16 months.   With all the great minds from both our companies working together, we will be able to help more customer on bigger and better projects.  

Many of you probably know Mike Labriola for his work on custom Flex Components, he has extended the Flex framework in ways that the developers at Adobe never even imagined.  He is also frequently speaking at conferences and User groups.  Both Nimer and I ran across him at dozens of speaking events across the country, and as we talked, we found there were far more similarities between us then differences. 

One of our first meetings at a conference ended up with him as a co-author on the Flex 2 book.  A year and a half of meeting at conferences later, and we were helping each other out on projects so frequently that it made sense to explore further integrating our companies.  When the opportunity for Nimer and I to join forces with him and his company, it was much too enticing to pass up.

We are looking forward to doing great work together, continuing to build cutting-edge applications for our clients, continuing to teach the world to build better RIAs, and continuing to serve the community.

Reflecting an image in Flex

Increasingly, clients have been asking for a "reflection" effect, showing a vertically flipped image of a component next to the actual component.  After reinventing the wheel on this several times, I came up with this simple reusable component:

package com.tappernimer.components{
import mx.containers.Canvas;
import mx.core.UIComponent;
import flash.display.BitmapData;
import flash.geom.Matrix;
import flash.display.IBitmapDrawable;
public class VerticalReflection extends Canvas{
private var _component:UIComponent;
public var trans:Number=.5;
public var filterArray:Array=new Array();
public var skewY:Number=0;
public var skewX:Number=0;
public function get component():UIComponent{
return _component;
}
public function set component(c:UIComponent):void{
this._component = c;
// hack to work around issue with component being 
// a dynamically loaded image its possible for the 
// image to be fully loaded, but its height or width 
// not yet set this call later, keeps retrying until 
// the values are set.
if(c.width ==0 || c.height==0){
callLater(resetComponent,);
return;
}
doReflection();
}
private function resetComponent(c:UIComponent):void{
this.component = c;
}
private function doReflection():void {
// create bitmap object
var bmpData:BitmapData = new BitmapData(
	component.width,component.height);
// create matrix
var invertMatrix:Matrix = new Matrix(1,skewY,skewX);
// set matrix to invert vertically, but normal horizontally
invertMatrix.scale(1, -1);
// move matrix, so top is at bottom, and vice versa
invertMatrix.translate(0, component.height);
// draw component flipped
bmpData.draw(component as IBitmapDrawable,invertMatrix);
// create a new holder for the image
var ref:UIComponent = new UIComponent();
// match new holders size to the original
ref.setActualSize(component.width,component.height);
// fill the new component with the image
ref.graphics.beginBitmapFill(bmpData);
ref.graphics.drawRect(0, 0, 
	component.width, component.height);
ref.graphics.endFill();
// set the transparency
ref.alpha = trans;
// apply any filters
ref.filters = filterArray;
// add image to stage
addChild(ref);
} 
}
}

This component can then be passed any other component to reflect, accepting filters (filterArray), alpha value (trans), and arguments to allow you to skew the reflection.  In fact, using it can be as simple as this:

<?xml version="1.0" encoding="utf-8"?>

<mx:Application xmlns:mx=http://www.adobe.com/2006/mxml 
xmlns:c="com.tappernimer.components.*" 
layout="absolute">
<mx:Image id="image" source="images/tn_logo_full.jpg"/>
<c:VerticalReflection id="ref" 
component="{image}" 
x="{image.x}" y="{image.height}" 
filterArray="{new Array(new BlurFilter())}"/>
</mx:Application>
Here is the code running:
