I personally use the command line tool gifsicle. png gifsicle -colors256 -delay4 -loopcount0 -dither -O3 gif/.gif. There are many ways to make animated gifs from frames. mkdir -p gif mplayer -ao null -vo gif89a:outdirgif INPUT mogrify -format gif. Resize animated gif to scaling to a given width. but there are some tools available to help you. How to make an animated gif from the frames gifsicle -scale 0.5 -i animation.gif > animation-smaller.gif. Animated GIF Utilities Animated GIFs have taken the Web by storm (again). Project description Python package wrapping the gifsicle library for editing and optimizing gifs. In this tutorial I used Processing but you can obviously do the same with your favourite programming tool that’s able to draw and save frames. gifsicle provides a -no-loopcount option when you process a GIF: gifsicle herrera-wtf.gif -no-loopcount > herrera-wtf-once. Latest version Released: Python package wrapping the gifsicle library for editing and optimizing gifs. SaveFrame(“fr#.gif”) saves frames with a number equal to frameCount and with leading zeros. Without optimization it would be roughly 3.5M. This will easily turn a 2.5M WebM file to a 600K GIF. Ive found that 600 pixels height is a nice compromise between size and readablility (when text is involved). I then use Gifsicle to resize and optimize the created GIF. In Processing frameCount is incremented each time Processing’s draw() function is called and it is equal to 1 on first call. To convert the WebM to GIF, I use FFmpeg. T can be defined as t = 1.0*(frameCount-1)/numFrames. So we want to save frames, for example numFrames = 100 frames from t=0 to t=1, but excluding t=1 because this frame is already saved at t=0 (or we take t=1 but not t=0). Note that if t goes from 0 to 1 (which will always be the case in those tutorials), the position at t=0 is the same as t=1. Hence if the radius of the circle is r, the position at time t can be defined with: The trajectory of the black dot can be described with maths: the angle depends on time and the radius is fixed. This tutorial is about making a basic perfectly looping gif with Processing: a dot doing a circular loop. Making a first gif with Processing - bleuje bleuje
