After Dark modules
After Dark is a screen saving shell.
It provides all of the support and
tools a programmer needs to quickly create unique screen saving
graphics. To create a new screen saver, you simply write a new graphics
module. A screen saver graphics module is a small, separately compiled
code resource. It is loaded into memory by After Dark when the user
places the pointer in a chosen corner of the screen, or after a
specified delay. You can develop a graphics module in any development
system that allows generation of code resources. This Programmer's
Manual is a description of the structure of a graphics module.
This manual is split into two parts. The first is a "Getting Started"
section that discusses the basic design of a graphics module and
provides the minimum material necessary to write a graphics module. The
second part covers advanced topics. These topics include After Dark
resources, full descriptions of data structures, and special features
provided by After Dark.
Included on the After Dark disk is source code in C and Pascal for the
MPW and Think programming environments. The source code demonstrates
how to write an After Dark graphics module.
