Specs
triangle( source :: Scenic.Graph.t() | Scenic.Primitive.t(), triangle :: Scenic.Math.triangle(), options :: list() ) :: Scenic.Graph.t() | Scenic.Primitive.t()
Add a Triangle to a graph.
Triangles are defined by three points on the screen.
Data:
{ {x0,y0}, {x1,y1}, {x2,y2} }
The following example will draw a triangle.
graph
|> triangle( {{10,20}, {100,20}, {50, 120}} )
Styles
Triangles honor the following styles
:hidden
- Iftrue
, the outline is rendered. Iffalse
, it is skipped. Default:false
.:fill
- Fills in the interior with the specified paint. If not set, the default is to not draw anything in the interior. This is similar to specifyingfill: :clear
, but optimized.:stroke
- The width and paint to draw the outline with. If the stroke is not specified, the default stroke is{1, :white}
.:join
- Specifies how the lines are joined together where they meet. Can be one of:miter
,:round
, or:bevel
. If join is not specified, then the default is:miter
.:miter_limit
- Apply an optional miter limit to the joints. If the angle is very shallow, the pointy bit might extend out far beyond the joint. Specifying:miter_limit
puts a limit on the joint and bevels it if it goes out too far.
Example:
graph
|> triangle( {{10,20}, {100,20}, {50, 120}}, fill: :red,
stroke: {3, :blue}, join: :round )
