◆ ApplyColorMatrix()

Color impeller::Color::ApplyColorMatrix ( const ColorMatrix &  color_matrix) const

A color filter that transforms colors through a 4x5 color matrix. 

   This filter can be used to change the saturation of pixels, convert
   from YUV to RGB, etc.

   Each channel of the output color is clamped to the 0 to 1 range.
