In ijlyttle/colorpath: Build Color Paths

Convert/coerce to CAM16-UCS matrix

Description

Convert/coerce to CAM16-UCS matrix

Usage

pth_to_cam16ucs(
  color,
  c = 0.69,
  Y_b = 20,
  L_A = 64/pi/5,
  whitepoint = whitepoints_cie1931("D65")
)

pth_new_cam16ucs(
  mat,
  c = 0.69,
  Y_b = 20,
  L_A = 64/pi/5,
  whitepoint = whitepoints_cie1931("D65")
)

Arguments

color	character or matrix with S3 class pth_mat, a representation of a color.
c	numeric surround parameter, between 0.535 (dark) and 0.69 (average).
Y_b	numeric background luminance.
L_A	numeric luminance of the adapting field (cd/m^2).
whitepoint	double array with one dimension, length three; describes the whitepoint reference for the color space.
mat	double matrix with three columns, one row for each color.

Value

double matrix with S3 classes pth_cam16ucs and pth_mat, with three columns, one row for each color.

Examples

  pth_to_cam16ucs("#663399")
  pth_new_cam16ucs(matrix(c(36.5, 18.4, -21.9), ncol = 3))
