MakeRGB15Pair

Creates a double 3DO RGB value out of separate red, green, and blue values.

Synopsis

uint32 MakeRGB15Pair (r, g, b)

Description

This macro creates a double 15-bit 3DO RGB value out of separate red, green, and blue values. The double part of the value comes from creating a 16-bit value and then merging it with a copy of itself shifted over 16 bits. The composite double RGB value this macro creates can be used as an argument to SetVRAMPages(), or anywhere else that the double RGB data type is required.

Arguments

r: The red value to be included in the RGB composite. This can be any integer value; the value is coerced by the macro to a uint32 value.

g: The green value to be included in the RGB composite. This can be any integer value; the value is coerced by the macro to a uint32 value.

b: The blue value to be included in the RGB composite. This can be any integer value; the value is coerced by the macro to a uint32 value.

The r, g, and b values must all be in the range 0-31.

Return Value

The macro returns a composite-double RGB15 value.

Implementation

Macro implemented in graphics.h V20.
