Text labels were not part of the original CIF syntax specification, so that various extensions are used to pass label information.
label_index | Historic Name | Format |
---|---|---|
0 | Xic | 94 «label» x y orient_code width height; |
1 | KIC | 94 label x y; |
2 | NCA | 92 label x y layer_index; |
3 | Mextra | 94 label x y layer_name; |
4 | none | no labels used |
Unlike other extensions, the first extension listed above is unique to Xic. If other formats are used, label size and orientation information will be lost. When reading CIF input, any of these forms will be accepted.
The default selections shown in the menus can be specified by setting the CIFoutStyle variable. When this variable is set, changing the selections in the menus will update the value of this variable. If this variable is not set, then reading in a CIF file will alter the menu selections so as to write a file in the same dialect. Otherwise, the defaults (the first choice in each menu) are used.
