GraphicsDepth ( )

Parameters

None.

Description

Returns the colour depth of the current graphics display, in bits.

This reports the depth the display was opened with. On the modern runtime the engine renders 32-bit colour, and asking Graphics for depth 0 (the default) reports 32 here.

Classic code used this to branch between 16 and 32-bit drawing paths; today it is mostly informational.
