ShapeDiver Image Sampler
The ShapeDiver Image Sampler component works similarly to the standard grasshopper Image Sampler, except the local input file is replaced by a Grasshopper Bitmap.
The component takes as inputs a Grasshopper Bitmap objects, a 2D coordinate point and a 2D domain. If the domain is left unspecified, it defaults to
[1, pixel width] x [1, pixel height]. It can be changed to any other 2D domain, typically
[0,1]x[0,1] for unitized pixel coordinates. The Coordinates (C) input needs to be given according the specified Domain (D) input.
