Example
<!--- Use ImageNew to create a 300x300-pixel image. --->
<cfset myImage=ImageNew("",300,300)>
<!--- Turn on antialiasing to improve image quality. --->
<cfset ImageSetAntialiasing(myImage,"on")>
<!--- Set the drawing axis to 30 degrees and the point of rotation at (10,10). --->
<cfset ImageRotateDrawingAxis(myImage,30,10,10)>
<!--- Set the drawing color to blue. --->
<cfset ImageSetDrawingColor(myImage,"blue")>
<!--- Draw three shapes with the same color and drawing axis. --->
<cfset ImageDrawRect(myImage,150,10,10,150,"yes")>
