Initializes a new instance of XMUBYTE2 from a two-element float array argument.

This constructor initializes a new instance of XMUBYTE2 from a two-element float array argument.

Note This constructor is only available with C++.

Syntax

void XMUBYTE2(
  const float *pArray
) noexcept;

Parameters

pArray

Two-element float array containing the values used to initialize the two components of a new instance of XMUBYTE2.

Return value

None

Remarks

The magnitude of each member of the pArray argument to the constructor will be clamped to the range supported by an 8-bit signed integer [0.0, 255.0].

The following pseudocode demonstrates the operation of this constructor:

XMUBYTE2 instance;

instance.x = (uint8_t)min( max( pArray[0] 0.0 ), 255.0 );
instance.y = (uint8_t)min( max( pArray[1] 0.0 ), 255.0 );
