RESAMPLE(1)                 General Commands Manual                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 standard input)
       to a new size.  Resample uses a Kaiser window which produces high qual‐
       ity  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 op‐
       tions.  An unadorned value sets the number of pixels 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 im‐
       age or change the pixel format, use iconv (see crop(1)).
