Playing with CF8 Image Functions

On December 12, 2007, in ColdFusion, by Anuj Gakhar

Here is what I did with the new CF8 image functions. This is actually drawn to the canvas and not just some text.

CFimage magic

Here is the code :-

<cfset myImage=ImageNew("",550,100,"rgb","3366aa")>

<!--- Set the drawing color to white. --->

<cfset ImageSetDrawingColor(myImage,"white")>

<!--- Turn on antialiasing to improve image quality. --->

<cfset ImageSetAntialiasing(myImage,"on")>

<!--- drawing attributes --->

<cfset attr = StructNew()>

<cfset attr.width = 4>

<cfset attr.endcaps = "round">

<cfset attr.lineJoins = "round">

<cfset ImageSetDrawingStroke(myImage,attr)>

<!--- draw the C --->

<cfset ImageDrawArc(myImage,10,10,110,80,105,145,"no")>

<!--- draw the F --->

<cfset ImageDrawLine(myImage,70,10,70,88)>

<cfset ImageDrawLine(myImage,70,10,120,10)>

<cfset ImageDrawLine(myImage,70,40,120,40)>

<!--- == sign --->

<cfset ImageDrawLine(myImage,150,40,190,40)>

<cfset ImageDrawLine(myImage,150,60,190,60)>

<!--- C again--->

<cfset ImageDrawArc(myImage,210,10,110,80,105,145,"no")>

<!-- O's --->

<cfset ImageDrawOval(myImage,250,10,90,80,"no")>

<cfset ImageDrawOval(myImage,350,10,90,80,"no")>

<!--- L--->

<cfset ImageDrawLine(myImage,450,10,450,90)>

<cfset ImageDrawLine(myImage,450,90,480,90)>

<!--- exclamation sign--->

<cfset ImageDrawLine(myImage,510,10,510,80)>

<!--- change the width for the dot--->

<cfset attr = StructNew()>

<cfset attr.width = 6>

<cfset attr.endcaps = "round">

<cfset ImageSetDrawingStroke(myImage,attr)>

<cfset ImageDrawPoint(myImage,510,90)>

<!--- Display the image in a browser. --->

<cfimage source="#myImage#" action="writeToBrowser">
