System Features
• Background
A DWORD value specifying the background color to use around graphics that are
smaller than the screen size. If not specified, the default background is 0x700000
(a middle range blue).
These value can be set using the Config Utility.
The program does not accept any command line parameters.
Once the program has read the registry entries, it tries to read a file named SlideShow.txt
from the graphics directory. If this file exists, it should contain one file name per line. These
file names should not include a path and they must exist within the graphics directory. The
files will be displayed in the order specified.
If the SlideShow.txt file is not present, the program will scan the graphics directory for all
files with the appropriate file name extensions. These files will be displayed in a sequence
that is determined by the file system.
If a slide is smaller than the screen size, it will be centered on the screen and the
background color will be drawn in the area around the slide. If a slide is larger than the
screen size, it will be scaled to fit on the screen. This scaling can result in a strange effect
if the slide is not proportional to the screen size. For best results, use slides that are the
same size as the screen. Source code is provided in the SDK (part number
MK2000CESDK-x.xx).
Other Inactivity Applications
Internet Explorer can be used as both the User Application and the Inactivity Application.
Media Player, as shipped with the operating system, provides a good example of how to
create a multi-media Inactivity Application (see the SDK for location of the source) but may
not be practical as an Inactivity Application because it does not cover the entire screen
space.
