ppmmix

Mix two images

$ ppmmix [factor] [image1.ppm] [image2.ppm] > [output.ppm]

$ ppmmix 0.5 [a.ppm] [b.ppm] > [blend.ppm]

$ ppmmix 0.25 [a.ppm] [b.ppm] > [output.ppm]

ppmmix factor file1 file2

ppmmix blends two PPM images together using linear interpolation. The mixing factor controls the contribution of each image: a factor of 0.0 produces entirely the first image, 1.0 produces entirely the second, and values between create a proportional blend.
Both input images must have the same dimensions. This tool is useful for creating crossfade effects, image compositing, and generating intermediate frames for transitions. Part of the Netpbm toolkit.

FACTOR

Mixing factor (0.0-1.0).

First input image.

Second input image.

Images must be same size. Part of Netpbm suite.

ppmmix was created as part of Netpbm for image blending.
