ppmfade - generate a transition between two image files using special effects
ppmfade [-f first.ppm] [-l last.ppm] [-mix|-spread|-shift| -relief|-oil|-edge|-bentley|-block] [-base name]
This program is part of Netpbm(1).
ppmfadegenerates a transition between either two input images or between one input image and black. You can use the 30 intermediate images generated to show a smooth transition between segments of a movie. The input and output images are in the PPM format. If you specify both input images, they should both be the same size. If you want to fade from black to an image, specify only the last image. If you want to fade from an image to black, specify only the first image. ppmfade names the resulting image files base.nnnn.ppm, where nnnn is a number varying between 0001 and 0030 and base is what you specify with via the -base option (default fade).
Another way to convert by steps from one image to another is morphing. You can use xmorph to do that.
In addition to the options common to all programs based on
libnetpbm (most notably -quiet, see
Common Options ), ppmfade recognizes the following command line
options:
ppmfade -f teapot.ppm -l pyr.ppm
Fade from teapot.ppm to pyr.ppm generating fade.0001.ppm to fade.0030.ppm using the "spread" transition.
ppmfade -l teapot.ppm
Fade from black to teapot.ppm generating fade.0001.ppm to fade.0030.ppm.
ppmfade -f teapot.ppm -base end
Fade from teapot.ppm to black generating end.0001.ppm to end.0030.ppm.
