Any of a number of predefined colors (red, green, blue, +cyan, +magenta, yellow, white) can be used, as well as allowing the color to +reflect +the natural color of that point in the colorspace.<br> +<br> +<b>-t</b> <i>trans</i> allows the transparency of the surface to +be +specified. A value of 0.2 might be a good place to start. Using +transparency +generally leads to a slower display than the default opaque surface +treatment, but can make it possible to see within a solid gamut surface.<br> +<br> +<b>-w</b> forces the gamut surface to be rendered as a wireframe.<br> +<br> +<b>-s</b> forces the gamut surface to be rendered as a solid surface.<br> +<br> +By default, the first gamut is treated as a solid with natural +coloring, +with the second and subsequent gamuts being wireframes with colors of +white, +red, cyan, yellow, green and blue, with decreasing visibility.<br> +<br> +The <b>-n</b> flag turns off display of the default L*a*b* axes in the +output.<br> +<br> +The <span style="font-weight: bold;">-i</span> flag computes the +intersecting volume of the first two gamuts (in cubic color units, +usually L*a*b*), as well as the volumes of the two gamuts and the +percentage the intersection is of the two gamuts. This is a useful +measure of the coverage one gamut has of another. If <span + style="font-weight: bold;">-I</span> is used, then as well as printing +the volume, the intersecting gamut will be saved to the <span + style="font-style: italic;">isect.gam</span> file.<br> +<br> +The final argument is the name of the VRML file to save the resulting +composite +3D visualization file to.<br> +<br> +</body> +</html> |
