I just posted this to the "cool things about cf" thread as an easy, useful
example of java instantiation.
<cfscript>
function bhimginfo(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");
bhImageInfo = StructNew();
bhImageInfo.ImgWidth = ImageObject.getWidth();
bhImageInfo.ImgHeight = ImageObject.getHeight();
bhImageInfo.SizeB = sizeb;
bhImageInfo.SizeKB = sizekb;
bhImageInfo.SizeMB = sizemb;
}
</cfscript>
It builds a structure called bhImageInfo that holds width, height and file
size (b, kb, and mb) about the image passed to it.
Just call it like so...
#bhimginfo('d:\path\to\image.jpg')#
Then dump bhimginfo to see everything returned
Also... dump imageFile to see a TON of other methods/properties that could
be used.

Subject: CFFILE action="upload"
All,
Does anyone know a way to check a image file's height and width before or
after an image has been uploaded? I'm restrictinig the file type for *.jpg
only.
I want to take the height and width values of the image being uploaded and
see if the values fall within an acceptable height and width range.
Thanks.
