Detecting Image Width

[weswhite7]

I want to detect the image width so if it is larger than a certain size, it will resize it down to a certain size, otherwise, it will leave it alone. I assume it is a simple cfif statement. The problem I believe I might have is that the file is already on the server.

I want to do this during the output stage on the page.

So if I have
<cfoutput query="thisquery">
<cfif (the width is greater than say 200 px show this image)>
<img src="#img1#" width="200">
<cfelse (for an image less than 200px or whatever the set width is)>
<img src="#img1#">
</cfif>
</cfoutput>

You'll need to use something like the Alagad Image Component to read the
image sizes:

or Massimos tmt_img

Well there is a problem, I can not have custom tags where we are right now. If we got a dedicated server which we may eventually, I might do that. What about doing this and creating a field in the database for the width. I know a guy in the past told me a way to do it on file upload using cffile.width I think. Is that what it is, or is it something different? I could just set that as a variable and place that to the database.

I guess my question now is, how to do it during cffile upload?

I don't think you can get the width during upload.

Well I am saying right after upload and cffile.serverfile returns you the name, I think you can get the width as well I just do not know the code for it. I know for a fact that you can get the file size because I used to check the size of the file and if it was over the limit I would turn around and delete it right there.

I am thinking I did check for the image dimensions as well to make sure it fit the box it was going in. I just do not remember the code for it.

Or are there even any cfscripts? I can use those tags and I do use that for a text format.
