Function Documentation

bit2mask()

constexpr std::size_t fluent_tray::util::bit2mask ( std::size_t bits )

inlineconstexprnoexcept

Generates a mask with the specified number of lower bits set to 1.

Parameters

[in]

bits

Number of bits

Returns

A generated bit mask.

concatenate_bits()

template<typename InType , typename OutType >

void fluent_tray::util::concatenate_bits ( InType upper, InType lower, OutType & out )

inlinenoexcept

Generates a variable that combines the bits of two variables.

Parameters

[in]	upper	A input upper bits.
[in]	lower	A input lower bits.
[out]	out	A output value.

split_bits

exists()

bool fluent_tray::util::exists ( const std::wstring & path )

inline

Checks if the file exists.

Parameters

[in]

path

A input wide string of path.

Returns

Returns true if the file exists, false if it does not.

rgb2gray()

unsigned char fluent_tray::util::rgb2gray ( const COLORREF & rgb )

inline

Calculate grayscale value from RGB.

Parameters

[in]

rgb

A input rgb value.

Returns

The grayscale value.

split_bits()

template<typename InType , typename OutType >

void fluent_tray::util::split_bits ( InType input, OutType & upper, OutType & lower )

inlinenoexcept

Divides the input value into upper and lower bits.

Parameters

[in]	input	A input value.
[out]	upper	A output upper bits.
[out]	lower	A outputs lower bits.

The splits is performed by storing the lower bits of number of bits of OutType in lower and the remaining bits in upper.
