ImageDrawQuadraticCurve

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

Syntax

ImageDrawQuadraticCurve(name, ctrlx1, ctrly1, x1, y1, x2, y2)

Arguments

Name	Type	Required	Description
name	any	Yes	The image or the name of a variable referencing an image to operate on.
ctrlx1	numeric	Yes	The x coordinate of the control point.
ctrly1	numeric	Yes	The y coordinate of the control point.
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.
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 quadratic curve drawn.

Description

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

Example

// Draw a quadratic Bézier curve
img = ImageDrawQuadraticCurve(myImage, 30, 40, 10, 20, 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 control point (ctrlx1, ctrly1), start point (x1, y1), and end point (x2, y2).
