Drawing portable graphics

Load the drawing conveniences and build a scene from regular .Graphics nodes:

Runnable RiXRun cell

.Plugin.Load("draw"); .Graphics.Graphic([420, 240], [ .draw.Box([20, 20], [380, 180], {= fill = "#f7fbff", stroke = "#9bb" }), .draw.Line([60, 160], [350, 55], {= stroke = "#2563eb", width = 3 }), .draw.Circle([200, 110], 24, {= fill = "#facc15" }), .draw.Label([190, 115], "P") ]);

The important boundary is invisible in the result: .draw.Circle simply returns .Graphics.Circle. This makes authored scenes portable to SVG, image, and future document renderers.

Use the lower-level .Graphics.Path, .Graphics.Text, and related core constructors directly when a plugin convenience is not the best fit.

Draft a labeled construction

Reusable styles, a viewport transform, dimensions, and anchors compose without creating a second scene format:

Runnable RiXRun cell

.Plugin.Load("draw"); ink := .draw.Style({= stroke="#1d4ed8", width=2 }, {= fill="none" }); paper := .draw.Style({= stroke="#cbd5e1", width=1 }, {= fill="none" }); view := .draw.Viewport([-2,-1,8,5], [600,360], {= margin=36 }); a := view.Point([0,0]); b := view.Point([6,0]); c := view.Point([2,4]); triangle := .draw.Polygon([a,b,c],ink); labelBox := .draw.Bounds(triangle); .Graphics.Graphic([600,360],[ .draw.Grid([36,36],[528,288],48,paper), triangle, .draw.Arrow(a,c,ink), .draw.Dimension(a,b,"6 units",ink,{= offset=20 }), .draw.Label(.draw.Anchor(labelBox,"north",[0,-10]),"Exact triangle",{= anchor="middle",size=15 }) ]);

Bounds uses renderer-independent drafting estimates for labels. A final renderer still owns exact font metrics.

Adapt geometry and annotate a path

Draw consumes geometry records by schema; it does not import the Geometry plugin or create a second scene representation.

Runnable RiXRun cell

.Plugin.Load("geometry"); .Plugin.Load("draw"); view := .draw.Viewport([-2,-2,2,2],[420,240],{= margin=24 }); a := .geometry.Point(-1,-1); b := .geometry.Point(1,1); segment := .draw.From(.geometry.Segment(a,b),{= viewport=view }); middle := .draw.Trim(segment,1/4,3/4); target := .draw.Symbol("target",[ .draw.Circle([0,0],4,{= fill="#f97316" }), .draw.Line([-7,0],[7,0],{= stroke="#7c2d12" }) ]); .Graphics.Graphic([420,240],[ segment, middle, .draw.Marker(middle,1/2,target), .draw.PlaceLabels([ {= id="a",position=view.Point([-1,-1]),text="A" }, {= id="near-a",position=view.Point([-1,-1]),text="exact point" } ]) ]);

An unresolved geometry result stays visible and retains its source evidence:

Runnable RiXRun cell

.Plugin.Load("geometry"); .Plugin.Load("draw"); parallel := .geometry.Intersect( .geometry.Line(.geometry.Point(0,0),.geometry.Point(1,0)), .geometry.Line(.geometry.Point(0,1),.geometry.Point(1,1)) ); .Graphics.Graphic([420,80],[.draw.From(parallel)]);
