常用示例
Generate CIE chromaticity diagram
ppmcie > [output.ppm]
Specify size
ppmcie -size [512] > [output.ppm]
Generate with specific illuminant
ppmcie -illuminant [D65] > [output.ppm]
说明
ppmcie generates a CIE chromaticity diagram as a PPM image, showing the full gamut of visible colors plotted on the standard CIE 1931 xy color space. The diagram is a standard reference in color science for visualizing color gamuts and comparing display or printing capabilities. Options control the output size, illuminant white point, and whether spectral wavelength labels are included. The generated image can be used for color science education, display calibration documentation, or as a reference overlay for gamut comparisons. Part of the Netpbm toolkit.
参数
- -size _N_
- Output size in pixels.
- -illuminant _NAME_
- White point illuminant.
- -spectral _N_
- Spectral type.
