常用示例
Interpolate image (scale up)
pnminterp [factor] [input.pnm] > [output.pnm]
Double image size
pnminterp 2 [input.pnm] > [output.pnm]
Triple image size
pnminterp 3 [input.pnm] > [output.pnm]
说明
pnminterp enlarges PNM images by an integer factor using bilinear interpolation. Unlike simple pixel replication (as done by pnmenlarge), interpolation produces smoother results by computing weighted averages of neighboring pixels. The scaling factor must be a positive integer, producing an output image that is N times larger in each dimension. This tool is a simplified interface to pamscale's interpolation mode. Part of the Netpbm toolkit; superseded by pamscale.
