NAME
resample - resample a pictureSYNOPSIS
resample [ -x size ] [ -y size ] [ file ]DESCRIPTION
Resample resamples its input image (default standard input) to a new size. The image is decimated or interpolated using a Kaiser window.The size of the resampled image can be specified with the -x and -y options. 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 and the output will be a compressed 24-bit r8g8b8 image. To uncompress the image or change the pixel format, use iconv (see
