CFpdf Tag Locking up my server 1

[LyndonOHRC]

I need to generate thumbnails of very small (100-130kb) PDF files. Every time I try to use the tag I have to restart the main ColdFusion 9.0 service; the "thumbnail" folder gets created, I never get any jpeg(s), and the server locks up completely.

Even this most basic form of the tag usage locks me up:

<cfpdf action="thumbnail" source="C:\myPDFs\Test1.pdf" overwrite="yes" imageprefix="thumb">

I also tried messing with pdf.js javascript library, supposed to generate thumbs too, but all the examples I found were very incomplete and way over my head I suppose.

Any help much appreciated.

I would say your path is wrong for the source.

source = "absolute or relative pathname to a PDF file|PDF document variable|

A little clarification on my response. If this is on a server on your computer even though the path is on your computer it would not be reachable by coldfusion. The file must reside within reach of the server. With most setups it would be 'C:\ColdFusion10\cfusion\

http://wwwroot\'

The source path I'm using is relative to the server. I used an example path in my post.

The path in your post would not be reachable by the coldfusion server. It can not go above the

http://wwwroot

folder. Try putting the pdf in the same directory with the file calling it and use this code.

<cfpdf action="thumbnail" source="Test1.pdf" overwrite="yes" imageprefix="thumb">

Same result. , I also tried a different pdf, not created with cfdocument...

What version coldfusion are you using? I would recommend a try catch to see any errors.

I'm using 9.0

Any idea what event I should "catch?

<cfcatch type="any">

<cftry>
<cfpdf action="thumbnail" source="Test1.pdf" overwrite="yes" imageprefix="thumb">
 <cfcatch type="any">
         <cfoutput>
          Error Message: #cfcatch.message#<br>

I tried this:

<cftry>
	<cfpdf action="thumbnail" overwrite="yes" source="C:/Workgroups/WebPages/binkley/BadgeCard/PDFs/2016-OC-276693.pdf" format="png" />
	<cfcatch type="any" name="myTry">
		<cfdump var="#cfcatch#" >
	</cfcatch>
</cftry>

I guess it can't get past the cfpdf tag. It never gets to the cfcatch or cfdump tags. Just hourglass, had to restart service.

But this works fine:

<cfpdf action="getinfo" name="myPDFinfo" source="C:/Workgroups/WebPages/binkley/BadgeCard/PDFs/2016-OC-276693.pdf" format="png" />
<cfdump var="#myPDFinfo#">

So, my guess is that the source attribute value is not the problem???

Thanks!!!

You should have gotten an error since it should be...

<cftry>
	<cfpdf action="thumbnail" overwrite="yes" source="C:/Workgroups/WebPages/binkley/BadgeCard/PDFs/2016-OC-276693.pdf" format="png" />
	<cfcatch type="any" name="myTry">
		<cfdump var="#myTry#" >
	</cfcatch>
</cftry>

I actually tried both. I'm really taking wild guesses now...

Is there a thumbnails folder in the directory? Perhaps it has to do with file permissions as it will need to create that directory if it doesn't exist.

Yes, it is creating the thumbnails folder, but it has no files in it. Maybe I should use cffile and copy a file into the new dir and see if I get a permission error?

Lyndon

 

[jdhilljr]

Sounds like a plan. Otherwise I think it's an Adobe question or a new install. I can find nothing with anyone having this problem and I think only changes in the IDE would cause it. I have tried having all files open and editing but can not produce an error.

CFFile copied a file into the thumbnails folder just fine...

Thanks for all of your assistance.

I hate things like this as they stick in my head lol Good luck. If I run across anything I will let you know.

I'm the same way, can't/won't give up, plus my customers need it.

I'm also looking at pdf.js as it's supposed to do this also. But all the examples I've found are really high level, and assume much more javascript skill than I have. I've got a few messages out there asking for a really simple PDF->JPG example, maybe I'll get some help there. I don't really care how this cat gets skinned. LOL

BTW, I graduated from MCRD, San Diego, in April of 1976. Did two years at 29-stumps then enlisted in the Air Force. Retired in 2005.
