Member Function Documentation

operator*() [1/3]

template<int D>

constexpr auto tt::geo::matrix< D >::operator* ( color const & rhs ) const

inlineconstexprnoexcept

Transform a color by a color matrix.

The alpha value is not included in the transformation and copied from the input. The color will be correctly transformed if the color matrix includes translation.

operator*() [2/3]

template<int D>

constexpr auto tt::geo::matrix< D >::operator* ( matrix< 2 > const & rhs ) const

inlineconstexprnoexcept

Matrix/Matrix multiplication.

operator*() [3/3]

template<int D>

constexpr auto tt::geo::matrix< D >::operator* ( matrix< 3 > const & rhs ) const

inlineconstexprnoexcept

Matrix/Matrix multiplication.

operator~()

template<int D>

constexpr matrix tt::geo::matrix< D >::operator~ ( ) const

inlineconstexpr

Invert matrix.

uniform()

template<int D>

constexpr matrix< D > tt::geo::matrix< D >::uniform ( aarect src_rectangle, aarect dst_rectangle, alignment alignment )

staticconstexprnoexcept

Create a transformation matrix to translate and uniformly-scale a src_rectangle to a dst_rectangle.

The implementation is located in scale.hpp since the definition requires both scale and translate.

Parameters

src_rectangle	The rectangle to be transformed.
dst_rectangle	The rectangle after transformation.
alignment	How the src_rectangle should be aligned inside the dst_rectangle after scaling and moving.

Returns

A transformation matrix to move and scale the src_rectangle to the dst_rectangle.
