Generate high resolution molecular image in Black & White format

[RohitPModani]

Hi,
I am currently using MolDraw2DCairo to create a /png molecular image. I am facing 2 issues which I have mentioned below. Please let me know how to fix these.

1. The image generated is of a very low resolution, and because of this it is blurr when i print it to pdf.
2. I am unable to generate the image in Black & White format. On Google it suggests to use 'useBWColourPalette' but this option is not available under MolDraw2DCairo.DrawOptions().

Please let me know how to fix these issues. I have pasted the code snippet below. Thank you.

var view = new MolDraw2DCairo(width, height);
view.drawMolecule(mol);
view.finishDrawing();
view.writeDrawingText(imageName);
