Unexpected output #8

Closed sorenoneill closed 4 years ago

The following R code does not produce the png output I was expecting:

bitmap <- rsvg(charToRaw(data[1,16]), width=450, height=500)

writePNG(bitmap, "svg2png.png")

The original svg file contains 7 paths but the result png file displays only two. Something is lost along the way ...

This example seems broken. Try again with rsvg 2.0, the results should be much better.

Indeed, I must have left something out of the example. Sorry! Its almost 2 years now, so I forget what the issue was. Closed.
