pnmsmooth(1) General Commands Manual pnmsmooth(1)NAMEpnmsmooth - smooth out an imageSYNOPSISpnmsmooth [-size width height] [-dump dumpfile] [pnmfile]DESCRIPTIONSmooths out an image by replacing each pixel with the average of its width X height neighbors. It is implemented as a C progam that gener- ates a PGM convolution matrix and then invokes pnmconvol.OPTIONS-size width height Specifies the size of the convolution matrix. Default size is a 3x3 matrix. Width and height sizes must be odd. Maximum size of convolution matrix is limited by the maximum value for a pixel such that (width * height * 2) must not exceed the maximum pixel value. -dump dumpfile Generates and saves the convolution file only. Use of this option does not invoke pnmconvol.SEE ALSOpnmconvol(1), pnm(5)AUTHORSCopyright (C) 1989, 1991 by Jef Poskanzer.
