Sorry, yes... it removes anything that isn't a letter, number, underscore or
hyphen
You could add dots to it as well if you want to run it against the whole
name including the extenstion...
[^a-zA-Z0-9-_\.]
So this:
Rereplace('joe_smiling (small).jpg', '[^a-zA-Z0-9-_\.]', '_', 'all')
Would result in:
joe_smiling__small_.jpg

>A safe bet would be rereplace [^a-zA-Z0-9-_]
Thank you very much.
I want to just implement it without getting it, but I can't. What would
that clear out? My guess is that it only allows a-z (and caps) and 0 to 9
(and maybe dash).
I do appreciate the help.

Thank you everyone - it's working now.
I have a related question, though it's not about referencing. It seems that
now that I'm going through java, the images often can't be read because
their title contains odd characters - characters that are fine in CF, for
example "joe_smiling (small).jpg". In this case the parens mess it up, but
I'm not sure what else might.
Clearly I should cleanse the image name on the way in. I don't work in java
much, so I'm not sure which chars to replace. I have something that
cleanses chars but it's not useful for this.
I've been googling for illegal path characters but haven't found a list
yet.

If set_size needs a reference to the image object, return the image object
from init_image and then pass it to the set_size function.

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>

Wow... that looks eerily familiar to this...
/*

function bhimginfo(imgfile){
var jFileIn = createObject("java","java.io.File").init(imgfile);
var ImageObject =
createObject("java","javax.imageio.ImageIO").read(jFileIn);
var ImageInfo = StructNew();
var imageFile = CreateObject("java", "java.io.File").init(imgfile);
var sizeb = imageFile.length();
var sizekb = numberformat(sizeb / 1024, "999999999.99");
var sizemb = numberformat(sizekb / 1024, "99999999.99");
var bhImageInfo = StructNew();
bhImageInfo.ImgWidth = ImageObject.getWidth();
bhImageInfo.ImgHeight = ImageObject.getHeight();
bhImageInfo.SizeB = sizeb;
bhImageInfo.SizeKB = sizekb;
bhImageInfo.SizeMB = sizemb;
return bhImageInfo;
}
:-)
Anyway... If you don't need to change it or lose it... just use a persistent
scope for it. Then you can pass it around to whatever you want.
function init_image()
{
application.imgObj = CreateObject("java","java.awt.image.BufferedImage");
application.imgRdr = CreateObject("java","javax.imageio.ImageIO");
}
function set_size(image_name){
f =
CreateObject("java","java.net.URL").init('http://www.sph.umd.edu/images/care
erexpo.jpg');
imgObj = application.imgRdr.read(f);
imgObj.imageWidth = imgObj.getWidth();
imgObj.imageHeight = imgObj.getHeight();
return imgObj;
}
