  15.      _o_p   one of the symbolic constants:
  16.           (parameters that affect lrectread, lrectwrite, rectcopy pixel
  17.           transfers)
  18.           HIST_ENABLE, default value:0. Enable hgram in lrectread, lrectwrite
  19.           and rectcopy pixel transfers. Value specifies the number of equally
  20.           spaced bins in the histogram. Valid values: 1 to 4096.
  21.           HIST_DISABLE, disable hgram.
  22.           HIST_CLEAR, clear every histogram bin to value
  23.  
  24.      _v_a_l_u_e
  25.           specifies the number of equally spaced bins in histogram if op is
  26.           HIST_ENABLE. Valid values: 1 to 4096. specifies the value to clear
  27.           the histogram to if op is HIST_CLEAR.

  30.      hgram allows enabling and disabling of the collection of histogram data
  31.      during pixel transfer operations (e.g., rectcopy, lrectread, and
  32.      lrectwrite). When hgram is enabled, the destination of the pixel transfer
  33.      operation is unaffected by the pixel transfer operation. The histogram
  34.      bins can be initialized by HIST_CLEAR.  Enabling and disabling of hgram
  35.      do not initialize the histogram, the initialization is done through
  36.      HIST_CLEAR.
