pdftowrite's Issues

'type' is not scriptable

Using python3.7, when I run this I get

Traceback (most recent call last):
  File "/usr/local/bin/pdftowrite", line 5, in <module>
    from pdftowrite.pdftowrite import main
  File "/usr/local/lib/python3.7/site-packages/pdftowrite/pdftowrite.py", line 5, in <module>
    import pdftowrite.utils as utils
  File "/usr/local/lib/python3.7/site-packages/pdftowrite/utils.py", line 16, in <module>
    def apply_vars(text: str, vars: dict[str,Any]) -> str:
TypeError: 'type' object is not subscriptable

Output svgz file makes Write crash (segmentation fault)

Here is the PDF file that I wanted to convert. Open the output file with Write and scroll to page 8 will make Write crash. Writing some strokes on page 7 and saving the file will also make Write crash. The message output by Write in the console is

[1]    2758388 segmentation fault (core dumped)  Write

Not sure whether this is a bug of Write.
Environment:

  • OS: Ubuntu 20.04
  • Python 3.10.6
  • pdftowrite 2021.05.03
  • Inkscape 1.2.2 (1:1.2.2+202212051550+b0a8486541)

modul typing throws error

Hello,
I use debian10 with python 3.7. After installation with pip the programm throws an error

def apply_vars(text: str, vars: dict[str,Any] -> str
TypeError: 'type' object is not subscriptable

I think this comes from the modul typing . In the documentation of typing it is Dict[] with capital letter.

I tried then on ubuntu21.04 . There is the other syntax accepted.

What is the reason for failure on debian10?

Sincerely, Helge
