Hi,

 

I use it from the cmd line all the time to create tests, so I prefer we keep it.

 

Thanks

Hello, may I suggest to consider removing the feature from user availability if 
it's not supposed to be used?

Is a patch worth it?

 

Regards

Hi,

 

AT is maintained only for unit tests, its missing many features so shouldn’t be 
used by a end user.

 

Thanks

Thanks Dave, I'll keep this info in mind. In the meantime I have tried the FOP 
"intermediate format" (IF) instead of the area tree, and I find I can export 
that, change it, and then read it in and publish it with no problems.

Hi Mark,

 

It might help narrow down on the issue if you tried an alternative JDK - I'd 
suggest Temurin jdk-11

 

It might also be a good time to update to the latest FOP version.

 

I've tried what you're attempting to do on Temurin 11 / FOP main branch and I 
had no issues.

 

Regards,

Dave

Subject: Publishing area tree XML fails 

 

I'm using FOP 2.4 on ubuntu. I create an area tree XML file on the 
command line with this:

fop -s topic.fo <http://topic.fo>  -at area_tree.xml

This works fine. I plan to make some changes and read it in, then 
publish to PDF.

I am trying to read it in and I don't know what to expect, or how to 
publish out to PDF. The docs do not go into this, that I can find. I get 
failure when I run the command below intended to produce a PDF called 
aaa.pdf:

fop -atin area_tree.xml aaa.pdf

Any ideas?

Thanks,
