Working with strings
The ASCII art version of the graphic is shown on the right.
To get the application files for this sample, see www.adobe.com/go/learn_programmingAS3samples_flash. The
ASCIIArt application files can be found in the folder Samples/AsciiArt. The application consists of the following files:
File Description
AsciiArtApp.mxml
or
AsciiArtApp.fla
Extracting tab-delimited values
Flash Player 9 and later, Adobe AIR 1.0 and later
This example uses the common practice of storing application data separate from the application itself; that way, if the
data changes (for example, if another image is added or an image’s title changes), there is no need to recreate the SWF

are used to manipulate the image, are stored in a text file (the txt/ImageData.txt file in the project). The contents of the
text file are as follows:
