Supplemental material

I recommend that you also study the other lessons in my extensive collection of online programmingtutorials. You will find a consolidated index at www.DickBaldwin.com .

General background information

The ActionScript documentation provides sample programs on the following web pages that cannot be run without modification in a Flex application, even whenthe entire application is programmed in ActionScript .

The problem is that these two sample programs were written to be compiled and run as pure ActionScriptprograms. There are some additional requirements that you must adhere to when writing bitmap programs to run as Flex applications.

Preview

I will explain two sample programs in this lesson. Both programs are scaled down versions of the sample program provided in the first link listed above .

The first program that I will explain can be compiled and run as a pure ActionScript program. The second program can be compiled and run as a Flexapplication with the majority of the code being written in ActionScript.

Run the online version of the programs

I encourage you to run the online versions of the two programs before continuing with this discussion.

Screen output from the program named Bitmap03

Both programs are designed to display a red square, 100 pixels on a side, with a yellow cross in the square.The screen output for the pure ActionScript program named Bitmap03 is shown in Figure 1. (Note that the yellow cross is much more visible in the original than in this screen shot.)

The size and position of the square varies

If you run the online version of this program, you will note that the size and position of the square varies depending on the width and height of thebrowser window.

Screen output from the program named Bitmap04

The program named Bitmap04 places the red square in a VBox container with a cyan background. The screen output is shown in Figure 2.

Although the VBox moves horizontally to remain centered in the browser window, neither the VBox nor the red square change size as the width and height of the browser window is changed.

Discussion and sample code

I will explain two programs in the remainder of this lesson.

The program named Bitmap03

Will discuss in fragments

I will explain the code for these two programs in fragments. Complete listings of all the code for both of the programs are provided beginning withListing 8 near the end of the lesson.

Beginning of the class named Bitmap03

This program consists of a single class definition file named Bitmap03 , which begins in Listing 1.

Beginning of the class named bitmap03.

package { import flash.display.Spriteimport flash.display.Bitmap; import flash.display.BitmapData;public class Bitmap03 extends Sprite {public function Bitmap03(){ var bitmapData:BitmapData =new BitmapData(100, 100, false, 0xFF0000);

what about nanotechnology for water purification
RAW Reply
please someone correct me if I'm wrong but I think one can use nanoparticles, specially silver nanoparticles for water treatment.

yes that's correct

industrial application...? mmm I think on the medical side as drug carrier, but you should go deeper on your research, I may be wrong
