A shape definition describes the components needed to render a shape. At the most basic level, a shape definition provides the geometry of the shape, which allows Lucidchart to produce path data. More complex shapes can contain sub-shapes that each have their own unique geometry, as well as sub-shapes of their own.

Manifest file

The manifest file defines the name and defaults for your shape:

{
    "name": "Test Library",
    "shapes": [
        {
            "shape": "first",
            "name": "Test Shape",
            "defaults": {
                "aspectRatio": .5,
                "fillColor": "#ff0000",
                "link": "your.url.com",
                "opacity": .5,
                "rotation": 1.5,
                "strokeColor": "#00ffff",
                "strokeWidth": 3,
                "height": 300,
                "width": 600
            }
        }
    ]
}

Shape file

Shape files are defined with JSON (or HJSON):

{
    "locked": ["aspectRatio"],
    "images": {
        "imageReference": {
            "path": "file",
            "type": "file",
        },
    },
    "geometry": [
        {
            "type": "rect",
        },
    ],
    "style": {
        "fill": {
            "type": "image",
            "ref": "imageReference",
            "mode": "stretch",
        },
    },
}
