background image - creating image masks

[konradmayer]

thanks for this great package!

I think it would could be very useful as an application for image analysis to create image masks (pixel selections). To do so it would be great to be able to display an image in the background (and define the grid based on image dimensions).
Unfortunately I cant write JS, but I suspect someone can implement it in the JS code which is called here:

pixels/R/show.R

Lines 58 to 64 in 32f7169

	htmlwidgets::createWidget(
	"pixels",
	x,
	width = size[[1]],
	height = size[[2]]
	)
	}
