pfsrotate(1)
NAME
pfsrotate - Rotate images 90 degrees.
SYNOPSIS
pfsrotate [--r] [--help]
DESCRIPTION
Use this command to rotate images from a stream of pfs. This command is
useful for output on hardcopy devices with aspect ratios opposite to
the input image. By default, the image is rotated clockwise. The --r
option may be used to rotate the image counter-clockwise instead.
OPTIONS
- --r, -r
- Rotate the image counter-clockwise instead of clockwise.
EXAMPLES
- pfsin memorial.hdr | pfsrotate -r | pfsout memorial_gc.hdr
- Rotate memorial image 90 degrees counter-clockwise and save to memorial_gc.hdr.
NOTES
To rotate an image 180 degrees, use pfsflip(1) with both the --h and
--v options specified.
