AZW3 to PDF: font size key doesn't work on all pages

[jee7no]

Hello, I'm converting a book from AZW3 to PDF. I went to Look & Feel, then I set these values:

Base font size: 12.0pt
Font size key: 12.0, 12.0, 12.0, 12.0, 12.0, 12.0, 12.0, 12.0, 12.0

Then I hit convert. I expected the output PDF to only use 12pt font.

Most pages are in 12pt font. However, random scattered pages are in a much smaller font, maybe 8pt.

Is this expected or is there a possible workaround to ensure the PDF only uses 1 font size?

Ah, whoops. Sorry, thanks for letting me know how to improve my question.

I've uploaded some files here: https://filebin.net/jj2hivx1lj7cxccc
It has:
1. A 3-page sample of the input azw3, input.azw3.
2. The resulting output pdf, output.pdf. For some reason this converts to more than 3 pages, but that's a separate issue.
3. The job details, job_details.log.

The only setting I tweaked was the font settings from above. There were no errors during conversion.

I also did a debug conversion and saw that the HTML files in the `processed` folder seemed to have the correct font size.

That's rather weird. I could workaround the issue by converting to epub first and converting that to PDF, but that should be unnecessary

It was caused by the large <pre> blocks that caused the browser tho shrink the font size to make it fit on the page. This should take care of it: https://github.com/kovidgoyal/calibr...6207afbed11933

Whoa, awesome! That fixed that page!

I cloned latest master and tested out the new changes on the whole book. Unfortunately, some pages later the small text returned. ^_^'

I uploaded new files: https://filebin.net/50a2d3t8nxtfsxot
* input_2.azw3 - starts at the same page as before, but added a few more pages
* job_details_2.log
* output_2.pdf - page 18, 20, 21 now have the small text

Also like before, the only settings I changed from the default are these:

Base font size: 12.0pt
Font size key: 12.0, 12.0, 12.0, 12.0, 12.0, 12.0, 12.0, 12.0, 12.0

Oh, interesting. I tried the work around you mentioned.

Going from AZW3 -> EPUB -> PDF seems to produce the best results.

AZW3 -> PDF seems to have more inconsistencies.

Oh, and just in case anyone else is watching. I did figure out how to get rid of the blank pages in the final PDF.

When converting from EPUB to PDF, I cleared the values of these text fields:
Structure detection > Detect chapters
Structure detection > Insert page breaks before path

Output PDF looks great now. Even the TOC is working great.

That will be because there is unwrappabe content in the <pre> block that does not fit, like a URL.
