A Base Canvas
Let's first build an empty canvas, then you can add the below objects into it. Paste the code below in your shot config -
{
"duration": 1000,
"objects": [
{
"type": "shape",
"kind": "rectangle",
"color": "#F2E880",
"comment": "base canvas",
"opacity": 1,
"position": {
"x": 0,
"y": 0
},
"size": {
"h": "700",
"w": "700"
}
}
A Line
Let's begin with the simplest of curves - A simple line object
{
"comment": "singular line ",
"type": "shape",
"kind": "line",
"opacity": 1,
"scale": 1,
"color": "gray",
"cap": "round",
"stroke": {
"color": "#051560",
"width": 10
},
"fill": "transparent",
"shadow": ["blue", 20, 2, 0],
"start": {
"x": 100,
"y": 300
},
"points": [
{
"x": 150,
"y": 350
}
]
}
you can add more points in the line to curve it like this -
{
"comment": "joined lines ",
"type": "shape",
"kind": "line",
"opacity": 1,
"scale": 1,
"color": "gray",
"cap": "round",
"stroke": {
"color": "#051560",
"width": 10
},
"fill": "transparent",
"shadow": ["blue", 20, 2, 0],
"start": {
"x": 100,
"y": 300
},
"points": [
{
"x": 150,
"y": 350
},
{
"x": 100,
"y": 400
},
{
"x": 150,
"y": 450
}
]
}
Field | Description |
|---|---|
type | shape |
kind | line (can be used to render a single line or multiple connected lines) |
stroke | line that follows the path of the curve |
stroke - color, width | to set the color and width in pixels. |
start (x, y) | Denotes the start of the line |
points (array of x, y) | Denotes the start of the line |
cap | Decides how the ends of the line should be drawn. Possible values for cap are butt, round and square. The default value is square. Diff types of caps can be seen here |
A Bezier Curve
Read more about the Bezier curve
To render a cubic Bézier curve - 4 points (start,end,control1,control2) are required.
{
"comment": "watermelon-bcurve",
"type": "shape",
"kind": "bcurve",
"color":"#F35588",
"stroke": {
"color": "#71A95A",
"width": 15
},
"start": {
"y": 40,
"x": 40
},
"end": {
"y": 40,
"x": 220
},
"control1": {
"y": 170,
"x": 40
},
"control2": {
"y": 170,
"x": 220
}
}
To get 'only' the curve try -
"color" : "transparent"
Field | Description |
|---|---|
type | shape |
kind | bcurve |
stroke | The line that follows the path of the curve |
stroke - color, width | To set the color in hex code and width in pixels. |
start | The start point of the curve denoted by x and y of start property |
end | The ending point for the curve denoted by the x and y of the end property. |
control1 | First control point used in the quadratic Bézier calculation denoted by x and y of the control1 property. |
control2 | Second control point used in the quadratic Bézier calculation denoted by x and y of the control2 property. |
