3 resample \- resample a picture
17 resamples its input image (default standard input) to a new size.
18 The image is decimated or interpolated using
21 The size of the resampled image can be specified
27 An unadorned value sets the number of pixels of that dimension; a suffixed percent sign specifies a percentage.
32 is given, the other dimension is scaled to preserve
33 the aspect ratio of the original image.
36 will reduce the image to half its original dimension in both
41 The input should be a Plan 9 image
44 and the output will be a compressed 24-bit
47 To uncompress the image or change the pixel format, use
53 .B \*9/src/cmd/resample.c
58 Faster algorithms exist, but this implementation produces correct pictures.
