常用示例
Spread pixels randomly
ppmspread [amount] [input.ppm] > [output.ppm]
Light spread effect
ppmspread 5 [input.ppm] > [output.ppm]
Heavy spread effect
ppmspread 20 [input.ppm] > [output.ppm]
说明
ppmspread randomly displaces each pixel in a PPM image to a new position within the specified radius, creating a scattered, noise-like blur effect. Larger spread amounts produce more diffuse results while small amounts add subtle texture. Unlike Gaussian blur which averages pixels, spread preserves individual pixel colors but randomizes their positions, producing a distinctive frosted glass or pointillist appearance. Part of the Netpbm toolkit.
