|
This assumes that the image was correctly computed in terms of |
| 133 |
|
luminance. |

|
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 |

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). |
