CFimage erro

[jfb00]

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!

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.

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

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.

Hi,

1. The value is fine because it works on and off.

2. I'm attaching the image. ( The image is fine)

Thanks!

The image works fine for me with CF9. Also, did you say you had or had _not_ verified the image path with FileExists()? That is an important step in troubleshooting. Even if you think the file exists, verify it anyway to avoid overlooking possible causes 😉

[jfb00]

Yes, I'm checking the fileExist(), also using cftry to see if it an error but everything is fine.

The error point to the line of cfimage.

Any other ideas?

Thanks!

Line numbers in error messages are not always accurate. Can you post the full code?

[jfb00]

Here is the code.

Is this available to the public?

I would like no to share this for security reasons.

Thanks!

Yes. It is a public site. If you can access these forums, so can everyone else 😉   Just xxx out anything confidential.  (I am assuming the problem code is not huge ...)

Is this any better

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

[jfb00]

That works!

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

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.

Application.url is a session variable, is set on the application.cfc.

I put an email tag to sent me the value all the time we try and sometimes came blank.

Thanks for your help!

Application.url is a session variable

Ummm.. that is an application variable, not a session variable.
