|
Display the radiance averaged over the area of interest. |
| 128 |
+ |
The maximum of the three (RGB) channels is reported. |

< |
Display the luminance value in the area of interest. |

> |
Display the photometrically-weighted luminance value in the area of interest. |
| 132 |
|
This assumes that the image was correctly computed in terms of |
| 133 |
|
luminance. |

< |
Display the color in the area of interest. |

|
Display the x and y location of the cursor. |
| 142 |
|
.BR i |
| 143 |
|
Identify identical pixels by assigning a random color at the cursor position. |
| 144 |
|
This is useful for displaying contours, especially when combined |
| 145 |
< |
with the -b option. |

This can be used as input to rtrace(1) to get additional information |
| 169 |
|
about the image (ie. pipe the output of ximage into rtrace). |
