@lukasholzer please, what rollup version are you using? (npm ls | grep rollup)

[lukasholzer]

rollup version 0.67.3

[ondras]

Looks like some breaking rollup API change. This seems to be the recommended way now: https://rollupjs.org/guide/en#generatebundle

I will fix this soon.

Turns out rollup is no longer providing the necessary data to the plugin. Filed an issue: https://github.com/rollup/rollup/issues/2578

Hi @lukasholzer,

I just published a new version (2.0.0) that should work with the very recent 1.0.0 rollup. Please try and confirm :)

@ondras could you also provide a dummy png as demoed output ?

[ondras]

Great idea, @y-nk ! I added a sample image and a description to the README.
