Classes

struct  default_color_converter_impl
 Color Convertion function object. To be specialized for every src/dst color space. More...
struct  default_color_converter_impl< C, C >
 When the color space is the same, color convertion performs channel depth conversion. More...
struct  rgb_to_luminance_fn
 red * .3 + green * .59 + blue * .11 + .5 More...
struct  default_color_converter_impl< gray_t, rgb_t >
 Gray to RGB. More...
struct  default_color_converter_impl< gray_t, cmyk_t >
 Gray to CMYK. More...
struct  default_color_converter_impl< rgb_t, gray_t >
 RGB to Gray. More...
struct  default_color_converter_impl< rgb_t, cmyk_t >
 RGB to CMYK (not the fastest code in the world). More...
struct  default_color_converter_impl< cmyk_t, rgb_t >
 CMYK to RGB (not the fastest code in the world). More...
struct  default_color_converter_impl< cmyk_t, gray_t >
 CMYK to Gray. More...
struct  default_color_converter_impl< C1, rgba_t >
 Converting any pixel type to RGBA. Note: Supports homogeneous pixels only. More...
struct  default_color_converter_impl< rgba_t, C2 >
 Converting RGBA to any pixel type. Note: Supports homogeneous pixels only. More...
struct  default_color_converter_impl< rgba_t, rgba_t >
 Unfortunately RGBA to RGBA must be explicitly provided - otherwise we get ambiguous specialization error. More...
struct  default_color_converter
 class for color-converting one pixel to another More...
