[Sidefx-houdini-list] How to scatter points based on a probability map

I want to scatter some points on a plane, depending on a density map or
probability map. The map will be black and white, white is probability
1 and black probability 0. Now I want to know the method or algorithm
to do this. I know that, we can use attribute in scatter sop, but the detail depends on the number of points in the source geometry. I want to do it using map. 
Another method to do that is using fur sop, and keeping only the root points. But I want to use the method in my own HDK, so if you can provide the algorithm, I can code it.
