Module Mlpost.Command
Basic drawing commands
type t
The abstract commands type
val draw : ?brush:Brush.t -> ?color:Color.t -> ?pen:Pen.t -> ?dashed:Dash.t -> Path.t -> t
Draw a path
- parameter color
the color of the path; default is black
- parameter pen
the pen used to draw the path; default is Brush.Pen.default
- parameter dashed
if given, the path is drawn using that dash_style.
val fill : ?color:Color.t -> Path.t -> t
Fill a contour given by a closed path
- parameter color
the color used to fill the area; default is black
val draw_pic : Picture.t -> t
draws a picture
val externalimage : string -> [ `None | `Width of Num.t | `Height of Num.t | `Inside of Num.t * Num.t | `Exact of Num.t * Num.t ] -> t
insert an image given its filename - *EXPERIMENTAL*
val nop : t
A command that has no effect
val append : t -> t -> t
Append two commands to form a compound command
val (++) : t -> t -> t
Abbreviation for append
val seq : t list -> t
Group a list of commands to a single command
val iter : int -> int -> (int -> t) -> t
iter m n f
builds a command that corresponds to the sequence of commands f m; f (m+1); ... ; f(n)
val iterl : ('a -> t) -> 'a list -> t
iterl f l
builds a command that corresponds to the sequence of commands f x1; f x2; ... ; f xn
for l = [x1;x2;...;xn]

Positions - they are used at many places in Mlpost to indicate a direction or position.
val label : ?pos:position -> Picture.t -> Point.t -> t
label ~pos:`West pic p
puts picture pic
at the left of the point p
val dotlabel : ?pos:position -> Picture.t -> Point.t -> t
Works like label
, but puts a dot at point p
as well
