Platform

Win32, x64

Purpose

To test if the screen is a high colour device.

Syntax

LOGICAL FUNCTION HIGH_COLOUR_MODE@( )

Description

A high colour device is one that has more than 8 bits per pixel (i.e. more than 256 colours). A high colour device does not make use of colour palettes. If you want to use a wide range of colours whilst avoiding the complexities of managing a palette, one solution is to restrict the usage to desktops operating in high colour mode. Thus you can use this function to test if the desktop is set to operate with more than 256 colours per pixel and to send a error message and close down on failure. All modern screens are high colour.

Return value

Returns .TRUE. for success.
