linescan2rasterindex

  LINESCAN2RASTERINDEX - Determine index values within a raster that correspond to points visited by a linescan

    INDS = LINESCAN2RASTERINDEX(IMSIZE, LINESCANPOINTS)

    Calculates the index values within a raster image of size IMSIZE that
    correspond to points on the linescan LINESCANPOINTS.  LINESCANPOINTS
    should be an N x 2 vector of points in units of pixels; column 1 corresponds
    to Y pixels and column 2 corresponds to X pixels.

    INDS is a list of index values such that RASTERIMAGE(INDS(n)) corresponds
    to the nth pixel in the linescan.  If the linescan is "out of bounds" at
    point i, then then INDS(i) is NaN.
