TPCB_PolygonSourceArray type

Single polygon source array

Signature

type TPCB_PolygonSourceArray = Array<'L' | 'ARC' | 'CARC' | 'C' | 'R' | 'CIRCLE' | number>;

Remarks

A single polygon is a region described by an unbroken line whose start and end coincide. If the start and end do not coincide, they will be automatically closed.

Example of the data format of a single polygon:

[300, 200, 'L', 400, 200, 'ARC', 400, 220, 15, 'C', 200, 500, 400, 300, 100, 100]

['R', 100, 200, 300, 300, 0, 0]

['CIRCLE', 100, 200, 5]

The data of a single polygon is composed of the following modes:

1. L line mode

x1 y1 L x2 y3 x3 y3 ...

• {number} x - X coordinate of the line point

• {number} y - Y coordinate of the line point

② ARC/CARC arc mode

ARC is two-point arc interaction, and CARC is center arc interaction

startX startY ARC arcAngle endX endY

startX startY CARC arcAngle endX endY

• {number} startX - Start X

• {number} startY - Start Y

• {number} arcAngle - Arc angle (negative values rotate clockwise; in degrees)

• {number} endX - End X

• {number} endY - End Y

3. C cubic Bezier mode

x1 y1 C x2 y2 x3 y3 x4 y4 ...

• {number} x - Control point X

• {number} y - Control point Y

④ R rectangle mode

R x y width height rot round

• {number} x - top-left point X

• {number} y - top-left point Y

• {number} width - width

• {number} height - height

• {number} rotation - rotation angle

• {number} round - corner radius

5. CIRCLE mode

CIRCLE cx cy radius

• {number} cx - center point X

• {number} xy - center point Y

• {number} radius - radius
