<!--- function to get the properties of the image file --->
<cfscript>
function get_imageinfo(imgfile){
jFileIn = createObject("java","java.io.File").init(imgfile);
ImageInfo = StructNew();
ImageObject =
createObject("java","javax.imageio.ImageIO").read(jFileIn);
imageFile = CreateObject("java", "java.io.File");
imageFile.init(imgfile);
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.SizeKB = sizekb;
get_imginfo.SizeMB = sizemb;
get_imginfo.ImageFormat = ListLast(ListLast(imgfile, "\"), ".");
}
</cfscript>
<cfset tmp = get_imageinfo("MYPATH\MYFILENAME") /> <!--- this is
the image file to get --->
<cfset width=#get_imginfo.ImgWidth#> <!--- this is
the resulting image width --->
<cfset height=#get_imginfo.ImgHeight#> <!--- this is
the resulting image height --->
<!--- now define what to test width and height against and what to
do --->
<cfif width gt MYMAXWIDTH or height gt MYMAXHEIGHT>
File To Large
<cfelse>
File OK
</cfif>
