Arguments
line_width
- Draw border line with line width line_width where _linewith is [1, 2, 3 ..]. 1 is the thinnest line, one pixel in width.
nrg
- Apply no regridding (decimation) of the grid.
col red | blu | gre |pin | tur | yel | whi | bla | bro
- Display the border line in color red / blue / green / pink / turquoise / yellow / white / black / brown
sav
- Save the border line in workspace ^bol. Make it active by mlo ^bol.
tub [factor]
- Display border line as a tube. The factor is a number larger than 0, relative to 1 (default), giving the thickness of the tube.
edge
- Display internal and external edges of the dataset.
fang feature_angle
- Controls the edge finding property. feature_angle is ...? The old Geocap logo uses fang 60.
flat level
- The border line result is displayed at z-level level. E.g. bol flat 200 will display the border line at z=200.
nodraw
- No display of border result. Often used with argument sav, where the border line is saved in a workspace.
