class HT_RGB32

class HT_RGB32

This class specifies a 4-byte RGB color value. Byte order is dependent on the platform and, in particular, on the "endian-ness" of the platform.

The order specified here is the case for Microsoft Windows platforms.

Operators

operator =             Assignment operator.

operator ==            Equality operator.

operator !=            Inequality operator.

Constructor

HT_RGB32               Create and initialize a HT_RGB32 object.

HT_RGB32::HT_RGB32

Purpose

Initializes a new HT_RGB32 object.

Synopsis

HT_RGB32()

HT_RGB32 (
    int r_in,
    int g_in,
    int b_in,
    int a_in = 0xFF
)

HT_RGB32 (HT_RGB32 const & in)

HT_RGB32 (HT_RGBA const & rgba)

Details

The first form initializes the HT_RGB32 object to an indeterminate value.

The second initializes it to (r_in, g_in, b_in, a_in),which should be between 0 and 255. If not supplied as argument, a_in takes the default value 255.

The third and fourth forms copy an existing HT_RGB32 or HT_RGBA to make a new HT_RGB32.

HT_RGB32::operator =

Purpose

Assignment operator.

Synopsis

HT_RGB32 const & operator= (HT_RGB32 const & in)

Details

Assigns the value of in to this object.

HT_RGB32::operator ==

Purpose

Equality operator.

Synopsis

HT_Boolean operator== (HT_RGB32 const & test) const

HT_Boolean operator!= (HT_RGB32 const & test) const

Details

The first operator returns true if test is equal to this object, false otherwise. The second operator reverses the truth values from the first form, but is otherwise the same.
