常用示例
Mix two images
ppmmix [factor] [image1.ppm] [image2.ppm] > [output.ppm]
50% blend
ppmmix 0.5 [a.ppm] [b.ppm] > [blend.ppm]
25% from first image
ppmmix 0.25 [a.ppm] [b.ppm] > [output.ppm]
说明
ppmmix blends two PPM images together using the specified fade factor. The factor controls the contribution of each image: 0.0 produces entirely the first image, 1.0 produces entirely the second, and values between create a proportional blend. The fade factor is applied to brightness, not light intensity. This means a linearly increasing fade factor between a black and white image produces linearly increasing perceived brightness, but the actual light intensity increases faster at the bright end. For light-intensity-based mixing, use pamcomp instead. Both input images must have the same dimensions and the same maxval. Part of the Netpbm toolkit.
