Parameter |
Description |
|---|---|
| name |
Required. The ColdFusion image on which this operation is performed. |
| x |
Required. The x coordinate of the rectangle. |
| y |
Required. The y coordinate of the rectangle. |
| width |
Required. The width of the rectangle. |
| height |
Required. The height of the rectangle. |
| arcWidth |
Required. The horizontal diameter of the arc at the four corners. |
| arcHeight |
Required. The vertical diameter of the arc at the four corners. |
| filled |
Optional. Specify whether the rectangle is filled:
|
The left and right edges of the rectangle are at x and x plus width, respectively. The upper and lower edges are at y and y plus height, respectively.
Set the filled parameter to yes to fill the rectangle with the current drawing color.
Use the ImageSetDrawingColor and ImageSetDrawingStroke functions to control the color and line attributes of the rectangle. Use the ImageSetAntialiasing function to improve the quality of the rendered image.
Example 1
<!--- This example shows how to draw a square with rounded corners. --->
<!--- Create a 200x200-pixel image. --->
<cfset myImage=ImageNew("",200,200)>
<!--- Set the drawing color for the image to blue. --->
<cfset ImageSetDrawingColor(myImage,"blue")>
<!--- Turn on antialiasing to improve image quality. --->
<cfset ImageSetAntialiasing(myImage,"on")>
<!--- Draw a blue filled square with round corners of arcWidth=10 and arcHeight=2. --->
<cfset ImageDrawRoundRect(myImage,5,5,190,190,"yes",10,2)>
<!--- Display the image in a browser. --->
<cfimage source="#myImage#" action="writeToBrowser">
Example 2
<!--- Create an image. --->
<cfset myImage = imageNew("",100,100,"argb")>
<!--- Create a text attribute collection. --->
<cfset textStruct = structNew()>
<cfset textStruct.size=16>
<cfset textStruct.style="bold">
<cfset textStruct.font="Trebuchet MS">
<cfoutput>
<cfloop from="1" to="20" index="i">
<!--- Turn on antialiasing to improve the quality of the rendered image. --->
<cfset ImageSetAntialiasing(myImage,"on")>
<!--- Set the background color. --->
<cfset ImageSetBackgroundColor(myImage,"cyan") />
<cfset ImageClearRect(myImage,0,0,myImage.getwidth(),myImage.getheight())>
<!--- Set the drawing color. --->
<cfset ImageSetDrawingColor(myImage,"black") />
<!--- Draw a rectangle with rounded corners. --->
<cfset ImageDrawRoundRect(myImage,10,10,myImage.width-20, myImage.height-20,i,i,"yes")>
<!--- Set the text arc value. --->
<cfset ImageSetDrawingColor(myImage,"##cccccc")>
<cfset ImageDrawText(myImage, "#i#",30,30,textStruct)>
<!--- Write the image to a file. --->
<cfset imageWrite(myImage,"#expandPath("#i#.png")#")>
<!--- Display the image. --->
<img src="#i#.png">
