RESAMPLE(1)                                           RESAMPLE(1)

     NAME
          resample, resize - resample a picture

     SYNOPSIS
          resample [ -x size ] [ -y size ] [ file ]
          resize [ -x size ] [ -y size ] [ file ]

     DESCRIPTION
          Resample and Resize resamples its input image (default stan-
          dard input) to a new size.  Resample uses a Kaiser window
          which produces high quality results and resize uses bilinear
          interpolation which is faster but produces more fuzzy
          images.

          The size of the resampled image can be specified with the -x
          and -y options.  An unadorned value sets the number of pix-
          els of that dimension; a suffixed percent sign specifies a
          percentage.  If only one of -x or -y is given, the other
          dimension is scaled to preserve the aspect ratio of the
          original image.  Thus, -x50% will reduce the image to half
          its original dimension in both x and y.

          The input should be a Plan 9 image as described in image(6),
          and the output will be a compressed 24-bit r8g8b8 image.  To
          uncompress the image or change the pixel format, use iconv
          (see crop(1)).
