ImageDrawCubicCurve

Draws a cubic Bézier curve on an image. This BIF allows you to specify the start point, two control points, and the end point for the curve in BoxLang.

Syntax

ImageDrawCubicCurve(name, x1, y1, ctrlx1, ctrly1, ctrlx2, ctrly2, x2, y2)

Arguments

Name	Type	Required	Description
name	any	Yes	The image or the name of a variable referencing an image to operate on.
x1	numeric	Yes	The x coordinate of the start point of the curve.
y1	numeric	Yes	The y coordinate of the start point of the curve.
ctrlx1	numeric	Yes	The x coordinate of the first control point.
ctrly1	numeric	Yes	The y coordinate of the first control point.
ctrlx2	numeric	Yes	The x coordinate of the second control point.
ctrly2	numeric	Yes	The y coordinate of the second control point.
x2	numeric	Yes	The x coordinate of the end point of the curve.
y2	numeric	Yes	The y coordinate of the end point of the curve.

Returns

• BoxImage: The modified BoxImage instance with the cubic curve drawn.

Description

ImageDrawCubicCurve draws a cubic Bézier curve on the specified image, using the provided start point, two control points, and end point. The image can be passed directly or referenced by variable name.

Example

// Draw a cubic Bézier curve
img = ImageDrawCubicCurve(myImage, 10, 20, 30, 40, 50, 60, 70, 80);

Notes

• All arguments are required.

• The image can be passed as a BoxImage object or as a variable name referencing an image.

• The curve is defined by the start point (x1, y1), control points (ctrlx1, ctrly1) and (ctrlx2, ctrly2), and end point (x2, y2).
