Python error - plugin doesn't work #3

Closed draken76 closed 5 years ago

draken76 commented 5 years ago

In QGIS 3.4.4 When executing plugin

_WARNING Traceback (most recent call last): File "C:/Users/xxx/AppData/Roaming/QGIS/QGIS3\profiles\xxx/python/plugins\polystrip\poly_strip.py", line 191, in run self.dlg.polystrip(layer) File "C:/Users/xxx/AppData/Roaming/QGIS/QGIS3\profiles\xxx/python/plugins\polystrip\poly_strip_dialog.py", line 51, in polystrip getAllPages(layer, width, height, srid, coverage) File "C:/Users/xxx/AppData/Roaming/QGIS/QGIS3\profiles\xxx/python/plugins\polystrip\poly_stripalg.py", line 69, in getAllPages azimuth = startpoint.asPoint().azimuth(endpoint.asPoint()) ValueError: Null geometry cannot be converted to a point.

Im not a programist, I don't know what to do with that.

thank you for your comment. As the plugin is still marked as experimental and my time is currently limited I would welcome contribution. I will try to fix the bug. To me it looks that there is no line layer loaded or selected. The plugin in its current version is not catching user-errors and does not have good documentation (see above - lack of time). You first have to load and select a line before using the plugin . - hope that helps

Hi! Thanks for your answer.

Line was added and selected. Whats more, I had your plugin working, and I was using it many times before. I still have it working in my office on QGIS 3.2. I have this python problem in my home computer with QGIS 3.4.4.

Because I was using your plugin many times, friends asked me to make a tutorial. And I created some data to show how to use polystrip along with atlas feature. [image: 01.png] What you can see above proves that I was succesfull with polystrip. Ok, let's remove this layer created some time ago in QGIS 3.2 Now it looks like that: Let's try it with the same line... [image: 02.png]

Select line... [image: 03.png]

Start plugin... [image: 04.png]

And... Kaboom... [image: 05.png]

But, as I mentioned, I'm not a programmer, and don't know what to do. [image: 06.png]

Of course, I will make this tutorial on 3.2, but I'm affraid thet ma colegues will ask: I'ts not working! Why??? So, please, try to find time to check what happened.

Best regards
