gives rows row1 through row2.

ImageTake[image,{row1,row2},{col1,col2}]

Details

  • ImageTake takes the rows of an image to be numbered from top to bottom, starting at 1.
  • ImageTake uses the standard sequence specification:
  • Allall elements
    nelements 1 up to n
    UpTo[n]elements 1 up to n
    -nlast n elements
    {n}element n only
    {m,n}elements m through n inclusive
    {m,n,s}elements m through n in steps of s
  • If fewer elements exist than are requested, ImageTake will just return the elements that are present.
