How to change image resolution?

[AllenDowney]

When fastdoc converts figures to png, the default resolution is too low for printing. Is there a way to either increase the resolution or generate pdf?

@AllenDowney it seems there is a hardcoded conversion value for the width of images in the code

I guess it would be great to have command line options for this or at least override this with an environment variable at runtime.

@maxpumperla Thanks for looking into this. I agree that it would be great if this were a command-line option.

For now I have worked around it by setting

plt.rcParams['figure.dpi'] = 300

At the top of the notebook and running it again.

good to know that works, thank you!
