Severity: important

Dear Maintainer,
* What led up to the situation?
The GUI does not start with command 'python3 -m pyimagetool'. An initial error
is produced:
>> OSError: Packaged data files are not writeable
$ python3 -m pyimagetool
Traceback (most recent call last):

It is possible to allow the package to write in the area area, but an other
error then comes in:

an image
28 def __init__(self, data: RegularDataArray, parent=None, layout=0):
AttributeError: type object 'Qt' has no attribute 'DashLine'
* What outcome did you expect instead?
The GUI, or a python Notebook should be usable, but this is not the case.
Considering that the code has not changed for 3 years, and that the
corresponding issue was sent https://github.com/kgord831/PyImageTool/issues/5
but had no answer, we recommend to drop this package.
