Is this.pdf.type = "classic" supposed to work and compatible with ColdFusion?

glasnhost · January 30, 2020, 1:50pm

I use Lucee 5.3.3.62 and I need to generate pdf exactly as in ColdFusion 11, which I believe use iText.

The new Lucee engine seems to be different (fonts different, images not rendered, sizes), so I tried to set this.pdf.type = “classic”.

But still there are many differences and some pdf generation is simply failing (produce a file with wrong format, or gives errors on some image manipulation)

Anyone tried this? any guidelines?
I’ll try to come up with more specific errors.

Here a first problem:
I tried this simple file

<cfdocument localUrl="yes" format="pdf" orientation="landscape" unit="cm" pagetype="a4">
<img src="pdfimage.png" width="200">
</cfdocument>

With Coldfusion, the image is rendered.
With Lucee, either with this.pdf.type=“classic” or not, no image is shown

tried also with localurl=“no” and full http url, same result

Zackster · January 30, 2020, 4:16pm

it’s always a good idea to check jira for known issues

https://luceeserver.atlassian.net/browse/LDEV-1716
https://luceeserver.atlassian.net/browse/LDEV-2556

alas, PDF support in Lucee is still rather rough around the edges

glasnhost · January 30, 2020, 4:47pm

I see…but I managed to make a virtual host work on the same machine.
Now this other virtualhost produces empty pdf…only thing I can see is this stackTrace.
And I checked the WEB-INF/lucee/fonts, should be ok

the question is also, it is possible to use iText like in CF (and maybe even paying the licence if necessary?).
I though that “classic” would do the trick.
This is really blocking

glasnhost · January 30, 2020, 5:18pm

Lucee is running on a EC2 Linux AMI

glasnhost · January 30, 2020, 5:24pm

and java version

/opt/lucee/jre/bin/java -version
openjdk version "11.0.3" 2019-04-16

Zackster · January 30, 2020, 5:42pm

I’m guessing your VM doesn’t have a desktop gui installed right? it’s headless right?

follow the links in this bug [LDEV-2619] - Lucee

could you add a note that you’re getting this with PDF as well to the task?

glasnhost · January 31, 2020, 11:29am

ok, I probably got rid of the
class sun.font.CompositeFont cannot be cast to class sun.font.PhysicalFont error, and I added the comment.
Images are still a problem though

The funny thing is that I have 2 virtual hosts on the same Lucee installation mapped to 2 Lucee Applications and one is working “more or less” fine, the other doesn’t and I can’t tell the difference

Zackster · January 31, 2020, 1:04pm

glad to hear your making progress! thanks for commenting in jira

out of interest, does it make a difference which virtual host, aka context gets hit first after a restart?

glasnhost · January 31, 2020, 4:06pm

hmmm no, I don’t think it matters.

I managed to render the image with localUrl=“no” and the image url.
Previously I didn’t realize that the url was not resolved on the server.

So it doesn’t seem to be really a PDF problem, rather the file is not found with localURL=“yes” on some hosts. With harcoded path, no path, or getTempPath()… no success.

The files are on the same EFS as the cfm page. Lucee is running on an EC2.
I don’t see however any weird in the logs. Maybe I don’t have logging enabled for pdf…

Zackster · January 31, 2020, 4:44pm

just had a quick squiz, don’t think there’s any logging in the pdf extension…

do you see any requests for the missing images from lucee in the webserver logs?

what file extensions do the images have? seems there’s some hard wired logic
to inline .jpg files as base64

We haven’t been able to make our applications produce PDF documents reliably with the new PDF engine. eg. <div style="position:absolute;top:100;left:200">some text</div> places text in the top left corner of the page. We’re still using PDF extension version 1.0.0.68 and Java 8 in our applications to keep PDFs working.
