Here is my script, movieB.sh: for f in *.ps Now, the subroutine outputs them as PostScript files, so first I do some conversions. Let’s say all my files have names of the form pXXXXX.ps, where XXXXX goes from 00001 to 99999. Systematic naming of the input files is very important. But what if I want to make a movie? Well, there are two tools that I use for this, gifsicle and ppmtompeg. So I can draw simple diagrams easily enough. These routines are just old Fortran 77 subroutines, and I have bunged them up on the web for reference and because they are still kind of useful. This is a problem for me because I am not really into computer graphics and the like - my scientific programming is all done in a text-based interface, with text files as inputs and outputs, and I do not have the time to spend learning GUI programming.īut, I do have some old PostScript routines that I use for printing stuff out when I have a simulation that is highly geometric in nature, for example something that involves atomic coordinates. As datasets get bigger and more and more imaging and modelling is done in three dimensions, being able to represent data graphically is more and more important. I’m not talking science fiction, but actual science. © 2022 parker higgins dot net by Parker Higgins is licensed under CC BY 4.Science and movies. Twitter should allow users to “hide” old tweets: my correct opinion If you make a lot of gifs and like to mess with a lot of values, it might make sense for you to do it graphically. Different source material calls for different settings, and I try to keep the final output as small as possible. Gifsicle -colors=256 -delay=4 -loopcount=0 -dither -O3 *.gif > animation.gifĪnd then tweak the parameters from there. Sometimes I cheat on the command line here, and just look at all the pictures with Preview or Image Viewer and delete the ones I don’t need.įinally, use gifsicle to wrap it all up into an animated gif. Then go through and remove the images at the start and the end that you don’t want in the final gif.In case you used any other format to output them, I use one line of imagemagick’s mogrify to convert them:

You now should have a directory full of stills.

GIFSICLE COMMAND LOOPCOUNT DOS DRIVER

You can put them into whatever directory you want of course.įor some reason the I don’t have the gif89a video output driver installed on my OS X computer, so I instead use png or jpeg in the place of gif89a up there. The next bit says to output gifs (that’s gif89a into the directory called “gif”.

GIFSICLE COMMAND LOOPCOUNT DOS MAC OS

On Mac OS X, first install the Homebrew package manager, and then install these programs withīrew install mplayer imagemagick gifsicle Sudo apt-get install mplayer imagemagick gifsicle On Ubuntu (or most anything Debian-based with large enough repositories - these are common programs) it should just be a matter of Make sure you have the programs installed. So I’ve worked out a process that uses the command line and requires only the programs mplayer, imagemagick, and gifsicle.

GIFSICLE COMMAND LOOPCOUNT DOS SOFTWARE

But because I don’t always have access to a bunch of graphics software, and because I might be using my Ubuntu or OS X box, it’s nice to have a process that works with widely- and freely-available free software command line tools. Sometimes I see a few seconds of a video I’m watching and I think that it’d make a great animated gif. Parker higgins dot net HOWTO: Create an animated gif from a video with command line tools
