Might I suggest Canvas.DrawPoints(float[], int, int, Paint)?

You'll need to rework your logic to create an appropriately formatted float[]
(which contains x/y pairs), and your existing algorithm isn't amenable to
determining which Paint color to use for the entire span, but (sanely done)
this should allow a number of Canvas.DrawPoints() calls which matches the
number of colors in your image, as opposed to the 512² (262144) JNI invocations
that your current approach would require.
