Updated PDF conversion help
I have a reworked version of reflow.py for the new PDF engine.
It seems to work better than the standard method, so I would like to publish it so that others can add improvements.

Before doing that, I need to update the Preferences settings to add new fields to assist the conversion. I have not been able to find the correct method for doing this.

I know the UI fields to set up, but I have not found out where/how to save these and pass them to the input.

I have not tested it with ebook-convert. I assume that also needs new command-line options.

Any help would be much appreciated.

Alan

I have now got the Calibre menu set up and working.

I have tried to build the command-line utilities, but I get errors when compiling PoDoFo.
I have Ubuntu 22.04 which loads PoDoFo 0.9.7.
I am guessing that Calibre uses a later -dev package, but I don't know which.

Does anyone know which package(s) I should be installing for the build.

The manual says:
git clone https://github.com/kovidgoyal/bypy.git
git clone https://github.com/kovidgoyal/calibre.git
cd calibre

but that creates a bypy directory, and a calibre directory which also contains bypy.
The build seems to run in the calible/bypy tree and the bypy tree doesn't contain the build scripts.

I am happy to commit the current changes, but it seems wrong to do half the job.

All help appreciated.

Alan

You will probably have better luck in the calibre development subforum.

https://www.mobileread.com/forums/fo...play.php?f=240

I think that you can have a moderator move your thread by reporting your post with the "!" button to the right of the "Karma" button at the bottom of your post.

You should not need to build calibre for this. Set up the calibre development environment as described in:

https://manual.calibre-ebook.com/develop.html

If you want to add options to the PDF input plugin, you just need to modify the plugins/pdf_input.py file to add the option. It will show up in ebook-convert automatically. To add it to the gui you need to edit convert/pdf_input.ui with qt designer to add the gui widgets for the options.

@kovidgoyal
I have the commit ready. Do I just append the changes file to this thread, or is there a better way? I don't want to publish the changes without others checking/testing them.

That requires a bug to attach it to.
Do you want me to create a new one, as there does not seem to be an existing one?
