	Pixel layout of pixel texture. Represent the ordering of pixel components with respect to a color space. The characters RGB does not mean the pixel is in RGB color space. It simply represents pixel components, using R, G, B as placeholders. More...

Functions
float64	ph::pixel_texture::uv_to_st_scalar (const float64 inputUV, const EWrapMode wrapMode)
	Transform (u, v) coordinates to (s, t) in [0, 1] according to wrap mode. This overload operates on single channel only. The transformation will preserve texel density as it originally is (e.g, no scaling effect).
math::Vector2D	ph::pixel_texture::uv_to_st (const math::Vector2D &inputUV, const EWrapMode wrapModeS, const EWrapMode wrapModeT)
	Transform (u, v) coordinates to (s, t) in [0, 1] according to wrap mode. The transformation will preserve texel density as it originally is (e.g, no scaling effect).
std::size_t	ph::pixel_texture::num_pixel_elements (const EPixelLayout layout)
std::size_t	ph::pixel_texture::alpha_channel_index (const EPixelLayout layout)
