Using this Python version of text2pdf

[Pedroski55]

I'm trying to convert text files to pdf. I want to set the page to A5, landscape.

To my surprise, I found this Python file in /home/pedro/.local/bin/ I ran this Python in a bash shell with absolute paths. I thought maybe there is another version of text2pdf somewhere, because some of my changes don't seem to work.

pedro@pedro-newssd:~/getEmailDataSummer2019/18BE/text2pdf$ for i in /home/pedro/getEmailDataSummer2019/18BE/text2pdf/*.txt; do /home/pedro/.local/bin/text2pdf -o "$i".pdf "$i"; done
pedro@pedro-newssd:~/getEmailDataSummer2019/18BE/text2pdf$

It works fine after I set the linesize in line 49 manually to 130.

I changed line 10 to size = 8
I changed line 24 (it was orientation='portrait') to

def make_pdf(afile, orientation='landscape', encoding='utf-8', point=(30, 20)):

so I would have landscape orientation, but I still get letter or A4, portrait.

I changed line 42. (It was A4) to:

printer.setPageSize(Qp.QPrinter.A5)

I still get A4 or letter, (not sure exactly) portrait.

Does anyone know why the page format does not change??

To get good control over pdfs, use pandoc.
