This should solve your problem. It's a function from one of my CF Components it
will return various image properties including the width and height (unless
it's CYMK, but then it will let you know that too).
Put the function below in a CFC.
<cffunction name="get_image_properties" returntype="any"
access="public" output="false">
<cfargument name="image_file" type="string" required="true" />
<cftry>
<cfscript>
jFileIn =
createObject("java","java.io.File").init(arguments.image_file);
ImageInfo = StructNew();
ImageObject =
createObject("java","javax.imageio.ImageIO").read(jFileIn);
imageFile = CreateObject("java", "java.io.File");
imageFile.init(arguments.image_file);
sizeb = imageFile.length();
sizekb = numberformat(sizeb / 1024, "999999999.99");
sizemb = numberformat(sizekb / 1024, "99999999.99");
get_imginfo = StructNew();
get_imginfo.ImgWidth = ImageObject.getWidth();
get_imginfo.ImgHeight = ImageObject.getHeight();
get_imginfo.ImageType =
ImageObject.getColorModel().getColorSpace().getType();
if (get_imginfo.ImageType eq 9) {
get_imginfo.ImageType="CYMK";}
else if (get_imginfo.ImageType eq 5) {
get_imginfo.ImageType="RGB";}
else {get_imginfo.ImageType="UNKNOWN";};
get_imginfo.SizeKB = sizekb;
get_imginfo.SizeMB = sizemb;
return get_imginfo;
</cfscript>
<cfcatch type = "any">
<cfscript>
get_imginfo = StructNew();
get_imginfo.ImgWidth = 0;
get_imginfo.ImgHeight = 0;
get_imginfo.SizeKB = 0;
get_imginfo.SizeMB = 0;
get_imginfo.ImageType = "UNKNOWN";
return get_imginfo;
</cfscript>
</cfcatch>
</cftry>
</cffunction>
Call the function with this:
<cfinvoke component="PATHTOCOMPONENT.CFCFILENAME" method="get_image_properties"
returnVariable="image_properties">
<cfinvokeargument name="image_file" valueTHE-FULL-PATH-TO-THE-IMAGE-FILE">
</cfinvoke>
To see what values are returned so you can determine what you have to use do:
<cfdump var="# image_properties #">

cfimage is really quite buggy... it has file locking issues.
you have to fiddle with the tag and function version until something works
reliably in a high demand environment. It is truthfully only marginally better
than the native java stuff.
