Mark (vz.Vz.Mark)

Mark alignement

type halign = [

]

The type for horizontal alignements.

type valign = [

]

The type for vertical alignements.

Mark constructors share the following optional parameters.

contour, if true ensures that the path defines a bounded area of the plane (defaults to false).
normalize, if true adjusts the size of the mark so that it's area is equivalent to size of a square of the given width.
path, the path to add the mark to (defaults to P.empty.). Marks always start a new subpath.
pos, the location of the mark (defaults to P2.o).
halign, mark horizontal alignement with respect to pos (defaults to `Center).
valign, mark vertical alignement with respect to pos (defaults to `Center).

val htick : 
  ?path:Vg.path ->
  ?halign:halign ->
  ?valign:valign ->
  ?pos:Gg.v2 ->
  float ->
  Vg.path

htick l is a horizontal tick of length l.

val vtick : 
  ?path:Vg.path ->
  ?halign:halign ->
  ?valign:valign ->
  ?pos:Gg.v2 ->
  float ->
  Vg.path

vtick l is a vertical tick of length l.

val dot : 
  ?path:Vg.path ->
  ?halign:halign ->
  ?valign:valign ->
  ?pos:Gg.v2 ->
  float ->
  Vg.path

dot w is a dot of diameter w.

val square : 
  ?path:Vg.path ->
  ?halign:halign ->
  ?valign:valign ->
  ?pos:Gg.v2 ->
  float ->
  Vg.path

square w is a square of side w.
