Question

CFimage erro

Hello,

I just update from CF7 to CF9 standard version and start using cfimage.

<cfset tempPath = "c:/images/#cffile.serverFile#" />
<cfset uploadedImage = "" />
<cfimage action="read" source="#tempPath#" name="uploadedImage"/>
<cfset headingWidth = uploadedImage.GetWidth() />
<cfset headingHeight = uploadedImage.GetHeight() />

I got this error pointing to cfimage line:

Detail

javax.imageio.IIOException:   Can't get input stream from URL!

Message

An   exception occurred while trying to read the image.

Any ideas?

Thanks!

Johnny

    <cfset tempPath = cffile.serverDirectory & "\" & cffile.serverFile>          
            <cfimage action="read" source="#tempPath#" name="uploadedImage"/>
            <cfset headingWidth = uploadedImage.GetWidth()>
            <cfset headingHeight = uploadedImage.GetHeight()>

    That works!

    Thanks for you help... looks like sometimes the session variable is blank.

    Regards

    Thanks for you help... looks like sometimes the session

    variable is blank.

    Hmm.. there are no session variables in the code you posted. But that is why it is important to post the actual code you are using and to verify all variables and assumptions in your code. I suspect you did not do that, or you probably would have identified the issue sooner But I am glad everything is working for you now.

    Strange, I would not expect that error from a local file.

    1) Is that the exact code you used or is there other code on the page?

    2) Does the error occur with all images, or just that one?

    3) Did you use FileExists() to verify the image path is valid? ie #tempPath#

    Hello,

    Thanks for you reply and help.

    1. In my path I'm using: <cfset tempPath = "#application.url#/sigs/#cffile.serverFile#" />

    But I check the result and it's fine.

    2. Just for some images, not for all.

    3.Yes, I'm checking for the file before if the file is not there, abort the process.

    Regards

    What is the value of #application.url# ? With the images that fail, does it happen consistently?  If so, can you upload one of them so we can test it.
