D3 SaveScreenShot

Nov 2, 2016 at 9:17 AM
Can someone help me to know if we can do these 2 things in some way.

1) Suppose i have a Dark colored D3 chart which has the data and i want to take its screen shot in white printable version without changing the actual color scheme.

2) Can i have a screenshot with a fixed resolution and quality of the chart without depending upon how small or big the chart is rendered on the screen?
