In which case, here's something I just did for a thumbnail upload. Basically, these
have a maximum size below which they are unaltered. I used imageMagick for the
transformation, but it was a bit overkill for the basic size check, so I used
imageInfo which is much quicker
(http://www.geocities.com/marcoschmidt.geo/image-info.html)
<!--- User wants to specify a thumbnail file --->
<cffile action = "upload"
fileField = "thumbfile"
destination = "#request.uploadPath#thumbs#request.filesep#"
nameConflict = "MakeUnique"
accept = "#request.thumbFileMimes#">
<cfset request.uploadedThumbFilename = cffile.serverFile>
<!--- Now we use an imported Java class (ImageInfo) to ascertain the size of the
uploaded thumb. The class needs a FileInputStream object to read --->
<cfset inputstream = CreateObject("Java", "java.io.FileInputStream")>
<!--- Load the thumbnail file into the input stream --->
<cfset
inputstream.init("#request.uploadPath#thumbs#request.filesep##request.uploadedThumbFilename#")>
<!--- Load the ImageInfo class --->
<cfset imageinfo = CreateObject("Java", "ImageInfo")>
<!--- Set the ImageInfo's input, which causes it to examine the image file --->
<cfset imageinfo.setInput(inputStream)>
<!--- Check that the image is OK --->
<cfif imageinfo.check()>
<cfif imageinfo.getwidth() gt request.maxImageWidth>
<!--- Image is outside the acceptable width, so we use imageMagick to resize it.
Note that the width is the limiting factor, and that the height is scaled
accordingly.--->
<cf_magicktag inputtype="file"
inputfile="#request.uploadPath#thumbs#request.filesep##request.uploadedThumbFilename#"
timeout="100"
action="convert"
outputType="file"
outputFile="#request.uploadPath#thumbs#request.filesep##request.uploadedThumbFilename#">
<cf_magickaction action="geometry"
width="#request.maxImageWidth#"
height="#int(imageinfo.getHeight()*(request.maxImageWidth/imageinfo.getWidth()))#">
</cf_magicktag>
</cfif>
<cfelse>
<!--- Image failed imageinfo check - that's bad, so abort. --->
<cflocation url="#request.self#?fuseaction=#fusebox.circuit#.error&errorindex=2"
addtoken="No">
</cfif>
</cfif>

ImageMagick is looking interesting.
