Introduction to Drawing Performance Guidelines

Unless you’re writing a command-line tool, your drawing code is an important area to tune for performance. Your application’s main drawing routines are called frequently to update the content of your windows. The faster these routines do their job, the more time there is for your application to do actual work.

This programming topic describes some basic ways to improve drawing performance in your code.
