The |
144 |
|
.I "\-o x0 y0" |
145 |
|
option specifies a nonzero anchor point for the bottom left image. |
146 |
+ |
If a negative value is given for ncols, then the rows are reversed, |
147 |
+ |
so they start from the top rather than the bottom. |
148 |
+ |
This gives a more natural ordering in most cases, but has the |
149 |
+ |
side-effect of moving any labels from the upper-left of each placed |
150 |
+ |
subimage to the lower-left. |
151 |
+ |
Also, the |
152 |
+ |
.I \-o |
153 |
+ |
option is interpreted differently, where the y0 value is number of |
154 |
+ |
pixels from the top (rather than the bottom). |

Since there is a limit to the number of open files and processes, |

large collections of images must be created in stages. |
