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. \fBppmfade\fP names the resulting image files +\fIbase\fP\fB.\fP\fInnnn\fP\fB.ppm\fP, where \fInnnn\fP is a +number varying between 0001 and 0030 and \fIbase\fP is what you +specify with via the \fB-base\fP option (default \fBfade\fP). +.PP +Another way to convert by steps from one image to another is +morphing. You can use \fBxmorph\fP to do that. + +.UN options +.SH OPTIONS +.PP +In addition to the options common to all programs based on libnetpbm +(most notably \fB-quiet\fP, see +.UR index.html#commonoptions + Common Options +.UE +\&), \fBppmfade\fP recognizes the following +command line options: + + +.TP +\fB-f\fP \fIfirst.ppm\fP +This is the image file (PPM format) to be used at the beginning of the +transition. If you don't specify this, the fade will start from black. + +.TP +\fB-l\fP \fIlast.ppm\fP +This is the image file (PPM format) to be used at the ending of the +transition. If you don't specify this, the fade will end with black. + +.TP +\fB-mix\fP +The two images are superimposed with the brightness of the first image +decreasing from full to none and the brightness of the final image +increasing from none to full. The transition is quadratic in brightness +with faster transition in the beginning and slower at the end. + +.TP +\fB-spread\fP +The pixels in the first image will be moved (spread) further and further +from their original location and then moved into the proper location in +the final image. This is the default transition. + +.TP +\fB-shift\fP +The pixels in the first image will be shifted further and further horizontally +from their original location and then moved into the proper location in +the final image. + +.TP +\fB-relief\fP +The first image is faded to a Laplacian relief filtered version of the +first image. This is then faded to a Laplacian relief filtered version +of the second image and finally faded to the final image. + +.TP +\fB-oil\fP +The first image is faded to an "oil transfer" version +of the first image. This is then faded to an "oil transfer" +version of the second image and finally faded to the final image. + +.TP +\fB-edge\fP +The first image is faded to an edge detected version of the first image. +This is then faded to an edge detected version of the second image and +finally faded to the final image. + +.TP +\fB-bentley\fP + The first image is faded to a "Bentley Effect" version +of the first image. This is then faded to a "Bentley +Effect" version of the second image and finally faded to the +final image. + +.TP +\fB-block\fP +The first image is defocused to small blocks. The small blocks are converted +to match a defocused version of the last image. The block version of the last +image is then focused to the final image. + +.TP +\fB-base\fP \fIname\fP +This forms part of the output filenames, as described above. + + + +.UN examples +.SH EXAMPLES + +\fBppmfade -f teapot.ppm -l pyr.ppm\fP +.PP +Fade from teapot.ppm to pyr.ppm generating fade.0001.ppm to fade.0030.ppm using +the "spread" transition. +.PP +\fBppmfade -l teapot.ppm\fP +.PP +Fade from black to teapot.ppm generating fade.0001.ppm to fade.0030.ppm. +.PP +\fBppmfade -f teapot.ppm -base end\fP +.PP +Fade from teapot.ppm to black generating end.0001.ppm to end.0030.ppm. + +.UN seealso +.SH SEE ALSO + +\fBtontsc\fP manual, +\fBsgifade\fP manual, +\fBsmart_vfr\fP manual, +\fBxmorph\fP manual, +.BR "ppm" (1)\c +\& + +.UN author +.SH AUTHOR +Bryan Henderson, Olympia WA; April 2000 +.PP +Inspired by and intended as a replacement for \fBpbmfade\fP (not a +Netpbm program) by Wesley C.
