### Syntax

```
imageDrawCubicCurve(name, ctrlx1, ctrly1, ctrlx2, ctrly2, x1, y1, x2, y2) returns void
```



#### Member Function Syntax

## CFML Engine Support

The imageDrawCubicCurve function is supported on the following CFML engines:

| Engine | Minimum Version | Notes |

## Examples


### Tag Syntax

This example shows how to draw a curved line that looks like a stylized 7. 

```
<!--- Use the imageNew function to create a blank ColdFusion image that is 200 pixels wide and 380 pixels high. ---> 
 <cfset myImage=imageNew("",200,380)> 
 <!--- Set the drawing color to magenta. --->  
 <cfset imageSetDrawingColor(myImage,"magenta")> 
 <!--- Turn on antialiasing to improve image quality. ---> 
 <cfset imageSetAntialiasing(myImage,"on")> 
 <!--- Draw a curved line that starts at (380,28) and ends at (32,56) with its first control point at (120,380) and its second control point at (5,15). ---> 
 <cfset imageDrawCubicCurve(myImage,120,380,5,15,380,28,32,56)> 
 <!--- Display the image in a browser. ---> 
 <cfimage source="#myImage#" action="writeToBrowser">  
```



### Using drawCubicCurve member function

CF11+ Lucee4.5+ Create a new image. With the new image draw a cubic curve, starting at top left (0,0) ending at bottom right (152,152) with 2 control points, 1 half way down the left side(0,71) and other at bottom left (0,152)

```
imgObj = imageNew("",152,152,"rgb","149c82");
imgObj.drawCubicCurve(0,0,0,71,0,152,152,152);
cfimage (action="writeToBrowser", source=imgObj);
```
