Poor image quality after saving

[Agucha1986]

Hi, I am using Leaflet to plot raster data, and everything looks good until I save the maps as PNG or any other format.

I use ESRI as the provider.

This is the code I used to save my maps as images.

saveWidget(m, file = "path.html")
webshot(url = "path.html", file = "path.jpeg", vwidth = 700, vheight = 500)

Is that an issue with the package, or is there a way to maintain/increase the resolution/quality of the image while saving the map?

Thank,
A
