XMUBYTE2::XMUBYTE2(constfloat*) function (directxpackedvector.h)
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 );
