The color inversion algorithm produces an output that is very similar to an old fashioned color film negative. The algorithm is economical to implement andtotally reversible. Therefore, it is used by several major software products to highlight an image and show that the image has been selected for processing.

Discussion and sample code

As mentioned earlier, I will explain two different programs in this lesson. One is named Bitmap05 and the other is named Bitmap06 .

The program named Bitmap05

Will explain in fragments

I will explain the code for both programs in fragments. Both programs use the same MXML code but use different ActionScript code. Complete listings of theMXML file and the ActionScript files are provided in Listing 19 through Listing 21 near the end of the lesson.

MXML code for the program named Bitmap05

The MXML code for this program (and the program named Bitmap06 as well) is shown in Listing 1 and also in Listing 19 for your convenience.

Mxml code for the program named bitmap05.

<?xml version="1.0" encoding="utf-8"?><!-- This program illustrates loading an image andmodifying the pixels in the image. --><mx:Application xmlns:mx="http://www.adobe.com/2006/mxml"xmlns:cc="CustomClasses.*"><cc:Driver/></mx:Application>

Both programs are written almost entirely in ActionScript. As you can see, the MXML code instantiates a single object of the Driver class. Beyond that point, the behavior of both programs is controlled entirely by ActionScript code in the Driver class.

ActionScript code for the program named Birtmap05

A security issue

Let me begin by saying that I make no claims of expertise regarding security issues and the Flash Player.

No embedded image

I did not embed the image file shown in Figure 1 in the SWF file for the program named Bitmap05 . Instead, I included it as a separate file in the Release Build of the program. As a result, it was necessary for me to change one of the XML elements in the following configuration file to makeit possible for you to download and run the online version of the program.

C:\Program Files\Adobe\Flex Builder 3\sdks\3.2.0\frameworks\flex-config.xml

(Note that the configuration file may be in a different location on your computer.)

The required change

The required change was to set the value in the following element to false instead of true:

<use-network>false</use-network>

Why am I telling you this?

The ActionScript documentation seems to take for granted that you must modify the configuration file to handle the security issue. However, it took a verylong time and a lot of searching for me to discover that in order to select certain compiler options, it is necessary to physically modify the configurationfile shown above.

I knew generally the kind of change that was required, but I was expecting to find an option in the Flex Builder 3 IDE to allow me to change the compileroptions on a project by project basis. If that capability exists in the IDE, I was unable to find it. (Of course, once you know about the requirement, you can Google "flex-config.xml" and find hundreds of references to the topic.)
