RE: CFIMAGE- stacking images
I see, what I was missing was definitely the functions. I am use to CF_Magicktag. I can't say I expected Ben Forta to respond to my message! That function works great for the appending, thank you. - Dan -Original Message- From: Ian Skinner [mailto:[EMAIL PROTECTED] Sent: Tuesday, January 29, 2008 1:24 PM To: CF-Talk Subject: Re: CFIMAGE- stacking images Ben Forta wrote: ImageNew() to create a new blank image.

Re: CFIMAGE- stacking images
Good point Ian. That's exactly what I tell folks as well. About the only thing I think the tag can do that the functions can't is the writeToBrowser action. Of course, CAPTCHA Is a _heck_ of a lot easier with the tag. On Jan 29, 2008 2:23 PM, Ian Skinner [EMAIL PROTECTED] wrote: Ben Forta wrote: ImageNew() to create a new blank image.

RE: CFIMAGE- stacking images
Here's an ImageAppend() function for you. Pass it two image paths, and the 3rd Boolean flag is TRUE (default) to stack images on top of each other, or FALSE to have them side by side. It returns an image object which you can save, or write to the browser with cfimage action=writetobrowser. --- Ben cffunction name=ImageAppend returntype=any output=yes cfargument name=image1 type=string required=yes cfargument name=image2 type=string required=yes cfargument name=vertical type=boolean required=no default=TRUE !--- Local vars --- cfset var resultImage= cfset var img1=ImageRead(ARGUMENTS.image1) cfset var img2=ImageRead(ARGUMENTS.image2) cfset var imgHeight=0 cfset var imgWidth=0 cfset var img2x=0 cfset var img2y=0 !--- Calculate size of new image --- cfif ARGUMENTS.vertical !--- Height is sum of both heights --- cfset imgHeight=ImageGetHeight(img1)+ImageGetHeight(img2) !--- Width is greater of the two widths --- cfset imgWidth=ImageGetWidth(img1) cfif ImageGetWidth(img2) GT imgWidth cfset imgWidth=ImageGetWidth(img2) /cfif !--- Location of second image --- cfset img2x=0 cfset img2y=ImageGetHeight(img1) cfelse !--- Width is sum of both widths --- cfset imgWidth=ImageGetWidth(img1)+ImageGetWidth(img2) !--- Height is greater of the two heights --- cfset imgHeight=ImageGetHeight(img1) cfif ImageGetHeight(img2) GT imgHeight cfset imgHeight=ImageGetHeight(img2) /cfif !--- Location of second image --- cfset img2x=ImageGetWidth(img1) cfset img2y=0 /cfif !--- Next create new image --- cfset resultImage=ImageNew(, imgWidth, imgHeight) !--- Paste first image --- cfset ImagePaste(resultImage, img1, 0, 0) !--- Paste second image --- cfset ImagePaste(resultImage, img2, img2x, img2y) cfreturn resultImage /cffunction -Original Message- From: Ben Forta [mailto:[EMAIL PROTECTED] Sent: Tuesday, January 29, 2008 2:18 PM To: CF-Talk Subject: RE: CFIMAGE- stacking images ImageNew() to create a new blank image.
