Images generated are low quality

Thanks for this app. It's great.

The .png image generated by selecting "Download" are low quality. They're all less than 40 KB and grainy. Can you improve the quality?

@IvanMwiruki Agree. But I can't commit any date to fix it due to the issues in other opensource projects I'm maintaining. Please feel free to raise a PR. Otherwise, I'll look into sometime in future.

Ok. No worries. Take your time. I found that if I select "Print" and save as a pdf I can get good quality images.
