Usage
Use the ImageSetDrawingStroke and ImageSetDrawingColor functions to control the appearance of the drawing point. For example, set the width attribute of the ImageSetDrawingStroke function to 10 pixels to draw a 20-pixel-square centered at (x,y). Use the ImageSetAntialiasing function to improve the quality of the rendered image.
Example
<!--- This example shows how to draw a large square in the middle of an image. --->
<!--- Use the ImageNew function to create a 200x200-pixel image. --->
<cfset myImage=ImageNew("",200,200)>
<!---Set the drawing color to orange. --->
<cfset ImageSetDrawingColor(myImage,"orange")>
<!--- Turn on antialiasing to improve image quality. --->
<cfset ImageSetAntialiasing(myImage,"on")>
<!--- Set the drawing area to 10 pixels. --->
<cfset attr = StructNew()>
<cfset attr.width = 10>
<cfset ImageSetDrawingStroke(myImage,attr)>
<!--- Draw the point at (100,100). --->
<cfset ImageDrawPoint(myImage,100,100)>
<!--- Display the image in a browser. --->
<cfimage source="#myImage#" action="writeToBrowser">
