Me And Ray Camden On ColdFusion 8 Image Goodness
Posted February 8, 2008 at 9:08 AM
ColdFusion master Ray Camden and I have started a project on RIAForge.org - ImageUtils.cfc - which is a collection of image related functions meant to extend the built-in ColdFusion 8 image manipulation functionality. We have kicked it off with four user defined functions:
DrawTextArea()
Draws text on the target image but will confine the text to width of the given text area. If there is more text than will fit on one line, the function automatically wraps the text to multiple lines. In addition to font, style, and size, the function also accepts the text property attributes LineHeight and TextAlign.
GetUrl()
Writes the image to ColdFusion 8's temporary image server applet and returns the absolute ("/path") URL to that image. Caution: the image is temporary and will only be available for a few minutes (aprox. 5 minutes).
MakeShadow()
Creates a drop shadow for the given image using the passed-in offset, blur factor, and drawing color. Caution: the drop shadow will increase the size of the canvas.
WriteToBrowser()
This function is meant to extend the functionality of the WriteToBrowser CFImage tag action. In addition to passing in the image, you can also optionally pass in the Alt, Class, and Style attributes to be used in the rendered IMG tag.
That's a good start, more to come soon. If there are any functions that you would like to see added (either existing functions of functions that you want us to generate), please let me know.

Never mind the details, who's the chick :-)
Oh sure... I tell you, then you tell some friends, then suddenly her phone's ringing off the hook and I look like the bad guy. I don't think so :)
I'm not sure if this is built in or not yet in CF8, but is there a good CAPCHA method? One that will create the image and then auto-delete itself after a minute or so.
Hi Ben,
sample image!!! she is HOT like your blog-posts LOL :)
Champ - CAPTCHA is indeed built in. Please read the docs on the CFIMAGE tag.
I liked the ad you created just above the comments - My husband is happier.... from housewife confessions. Now THAT was creative.
@Chris,
Thanks :)
