Example: ASCII Art 221
The ASCIIArt application files can be found in the folder Samples/AsciiArt. The application
consists of the following files:
Extracting tab-delimited values
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 file. In this case, the image
metadata, including the image title, the URL of the actual image file, and some values that 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:
FILENAMETITLEWHITE_THRESHHOLDBLACK_THRESHHOLD
