Converted image all black #20
Comments

Same issue here. Convert Image button turns the graph black. Tried installing your fix using pip command from a different post and still have the problem. Also tried using different data part types like area or stacked and it didn't change. Would be great to see a fix! |

@gcaha I used the pip command fixes from issue #21 and managed to get it to work, i.e. the converted image isn't all black. It initially did not work, but I think an important step is to uninstall previous matplotlib, as zhouborui97 commented, and install version 3.4.3. I still had issues with the automatic detection of sample points last time I used it, but uncertain whether that is due to image quality or something else. I made sure that I could still convert the image with the fix before commenting this though. |

Hi, I now rolled back matplotlib back to 3.4.3 and double checked version with pip list. Then reapplied the fix but still finding the problem. Did you also have to do the comment out line #59 in setup.py? I didn't do this step b/c the program launches, but just still turned the image black. I also tried reinstalling then reapplying the fix and made sure matplotlib stayed at 3.4.3 but no luck. I think there must be some other conflict or newer package that is conflicting now. Thank you for the help.

That is too bad! It was some time back now, but I seem to remember that I did a fresh install, used the fix Chilipp added in the response to issue #22 and rolled back the matplotlib. I am unsure whether I used the first fix:
Or second approach: I at least know that I didn't need to comment out that one line in setup.py. |
Screenshot
Converted image turns fully black
Actual diagram for comparison
Problem description
After selecting the data the converted image turns all black as in screenshot above.
Expected Output
The converted image should be a binary (black/white) image of the actual diagram but instead fills the selected data area with black. I have attempted to reinstall straditize as well as update dependencies with no change. On a previous installation on my laptop straditize worked fine (spring/summer 2020), but upon installing recently on another computer this issue appears. Fresh install on my laptop created the same issue, this was needed as straditize would not launch on the laptop.
