说明
pamstretch-gen scales a Netpbm image by an arbitrary (possibly non-integer) factor. Internally it upscales to the next integer multiple with pamstretch (which only supports integer factors) and then uses pamscale to scale back down to the requested size, producing higher-quality results than pamscale alone for modest upscaling. There are no command-line options specific to pamstretch-gen; it recognizes the common libnetpbm options (for example `-quiet` and `-plain` on recent versions).
