Lines on PNG mark up showing up jagged

Lines on PNG mark up showing up jagged in Rhino WIP but shows correct in Rhino 7. Please help

Hi Anton -
We know about the antialiasing issue and are going to try and improve it.
This is not limited to curves drawn over a bitmap, though.
You could try to create a new linetype with an extra pixel or two for the curve width and see if that helps for the time being.
