Graphics Primitives by Phillip Burgess
Each device-specific display library will have its own constructors and initialization functions. These are documented in the individual tutorials for each display type, or oftentimes are evident in the specific library header file. The remainder of this tutorial covers the common graphics functions that work the same regardless of the display type.

The function descriptions below are merely prototypes — there’s an assumption that a display object is declared and initialized as needed by the device-specific library. Look at the example code with each library to see it in actual use. For example, where we show print(1234.56), your actual code would place the object name before this, e.g. it might read screen.print(1234.56) (if you have declared your display object with the name screen).
