Name

       setpix - Set FITS or IRAF image values

Synopsis

       setpix [-vn] file.fts [x_range y_range value] [@valuefile]

Description

       Set  a  specified  pixel  or  range of pixels in a FITS or IRAF image to a specified value. More than one
       range of pixels and values may be specified on one command line. A file of xrange yrange  value  triplets
       may be used to set multiple regions at once. The image may be overwritten or a new image created.

Options

       filename
              Name of IRAF image header file or FITS file. This must be present.

       @coordfile
              Name of file containing lines of the format
                       xrange yrange value where xrange and yrange are of the format n or n-n or n,n,n or n-n,n-
              n and value my be integer or floating point.  value will be converted to the type of the image. If
              a  range  is  0, the entire row or column specified by the other non-zero range will be set to the
              indicated value. If both ranges are zero, the entire image will be set  to  the  specified  value.
              New in version 2.6.4.

       xrange yrange value
              Image  coordinate  x  and  y  ranges and the value to which that region will be set. Either one of
              these triplets or a file of triplets, specified by @filename, must be present. xrange  and  yrange
              are  of  the  format n or n-n or n,n,n or n-n,n-n and value my be integer or floating point. value
              will be converted to the type of the image. If a range is 0, the entire row or column specified by
              the  other  non-zero range will be set to the indicated value. If both ranges are zero, the entire
              image will be set to the specified value. Ranges new in version 2.6.4.

       -a <number>
              Add constant to pixels

       -d <number>
              Divide pixels by constant

       -i     List each line which is dropped

       -m <number>
              Multiply pixels by constant

       -n     Write the output to a new file which is named by inserting an e before the file extension. The new
              file is always written to the current working directory.

       -s <number>
              Subtract constant from pixels

       -v     Print more information about the process
