Recently, someone has posted how to check image sizes using java in
CF. I have hundreds of images to check on one page where the images
are entered by users. On the code that was posted, a java object is
created and then a pict is assigned to it. It would seem that since
I am doing lots of images, I shouldn't create an image object each
time, just the picture object (f). So I broke them into two batches
of script, but I'm getting the error stating that imgRdr is undefined
(cause it's in another function). I'm not sure how to reference this
var or if the rest of this is gonna work or if it's a good idea at
all. Any thoughts?
Here's the code:
<cfscript>
function init_image (){
imgObj = CreateObject
("java","java.awt.image.BufferedImage");
imgRdr = CreateObject
("java","javax.imageio.ImageIO");
}
function set_size(image_name){
f = CreateObject("java","java.net.URL").init
('http://www.sph.umd.edu/images/careerexpo.jpg');
imgObj = imgRdr.read(f);
imgObj.imageWidth = imgObj.getWidth();
imgObj.imageHeight = imgObj.getHeight();
return imgObj;
}
</cfscript>
