bin        Bin down image  

 

image format: SPIDER

SEE ALSO:  bin density (Bin down image and convert to optical desities)


USAGE:    bin

          .INPUT FILE: image4086
          [Enter the name of the image containing transparencies]

          .OUTPUT FILE: red4086
          [Enter name of output file]

          .Size reduction factor for binning (def. 1): 3
          [Enter a binning factor if you want to reduce the image size and 
           increase the pixel size. Note: in some cases binning can cause 
           aliasing. Normally though the true resolution of the image is 
           lower that the Nyquist limit of the scan.]
 
          .Scale factor of density (def 1.): 1.0
          [Enter an optional scaling factor for the density values.]

Notes:    The program bins down an image by an integer factor. The new 
          dimension is calculated byinteger division. If there is a remainder, 
          the corresponding pixels at the end of the rows and columns in the 
          original image are ignored.
