GDSII Format Cutout
When specifying --gds-out option at startup, figures will be cut out in GDSII format after launch.
You can also specify the area or Area File to be output to the cutout file using --cutout-area option.
By specifying as follows, the specified range of figure_file will be cut out to cutout.gds:
$ nebv --cutout-area="0,0,100,100" --gds-out=/path/to/cutout.gds /path/to/figure_file
$ nebv --cutout-area=/path/to/areafile.txt --gds-out=/path/to/cutout.gds /path/to/figure_file
For Area File syntax, Refer to Area File page.
See --gds-out, --cutout-area in Boot Options page.
Other Format Cutouts
Like GDSII, cutting out in other formats is also possible.
See --ebv-text-out, --oasis-out, --oasiscl-out, --cutout-area in Boot Options page.
