![]() Svgasm has been tested to work with the following cleaners: primitive: running the command go get -u /fogleman/primitive.autotrace: downloading a release binary from the release page of autotrace or install with a package manager.svgo: running the command npm install -g svgo or yarn global add svgo.Sudo pacman -S svgcleaner potrace graphicsmagick Installing optional runtime dependencies To install and run a pre-compiled binary of svgasm on macOS with Homebrew installed, run the following commands, which would also install dependencies svgcleaner, potrace and graphicsmagick: Generates output animation.svg from animation1.gif and animation2.gif that animates with the same time delay and iteration count as the first GIF file. svgasm animation1.gif animation2.gif > animation.svg. ![]() Generates output animation.svg from intro.jpg and wild card frame*.png that animates with 30 frames per second, iterates infinitely, and with loading text turned off. svgasm -d 1/30 -l '' intro.jpg frame*.png > animation.svg.Generates output animation.svg from input1.svg, input2.svg and input3.svg that animates with a delay of 2 seconds per frame, iterates 5 times, and stops at the first frame in the last iteration. svgasm -d 2 -i 5 -e 0 -o animation.svg input1.svg input2.svg input3.svg.m command for magick program for GIF animation with %s (default: 'gm %s') t command for tracer for non-SVG still image with "%s" (default: 'gm convert +matte "%s" ppm:- | potrace -svg -o -') c command for SVG cleaner with "%s" (default: 'svgcleaner -multipass -c "%s"') s extra CSS styles definition in output (default: '') l loading text in output or '' to turn off (default: 'Loading. e index of frame to stop at in last iteration if not infinite (default: -1) i animation iteration count (default: infinite) p prefix added to element IDs (default: _) o path to SVG animation output file or - for stdout (default: -) d animation time delay in seconds (default: 0.1) (An alternative approach would be to re-program plot generation with a JavaScript library like D3.js to have the browser generate the values of text, paths, gradients, etc.) Usage Notably, svgasm does not use JavaScript in SVG output. The following example is a 30-fps 41-frame animated contour plot of F β score from a sequence of 41 plots pre-generated using matplotlib animated with svgasm. While the above two examples can be created with CSS animation with some effort without the help of svgasm, the following example is not so easy. SVG animation from multiple still SVGs Show build status badge exampleĪn example of a 2-fps 2-frame animated build status badge for this project is generated using svgasm from 2 GitHub Workflows status badge SVG files.Ī worked example of a 1-fps 2-frame animated calendar plot in examples/calplot_animation.ipynb (Jupyter Notebook) is generated using calplot and svgasm. Svgasm -t 'gm convert "%s" png:- | primitive -i -o -n 250' examples/_lions.gif > examples/lions.svg Input GIF (2,180 KiB) While primitive is not a tracer, it can be used for raster-to-vector conversion with aesthetically pleasing results. Svgasm -t 'gm convert -negate "%s" pgm:- | mkbitmap -x -f 1 -s 1 -o - | potrace -t 0.4 -svg -o -' -s 'svg ' examples/_anime.gif > examples/anime.svg Input GIF (1,616 KiB) The SVG output is hence black-on-transparent but restyled to white-on-black to match the input GIF. Note that colors are inverted with gm convert -negate to obtain black-on-white images before tracing with potrace.

Executes image processor graphicsmagick (by default) or imagemagick to convert GIF animation to frames.Įxamples SVG animation from single GIF using tracer.Executes bitmap tracer potrace (by default) or autotrace, or primitive to convert raster image input to SVG.Executes SVG cleaner svgcleaner (by default) or svgo to minify each SVG file.Produces single animated SVG file that is viewable in Chrome, Safari, Firefox, Edge and IE 10+.Steps listed in reverse order of execution: Svgasm is a proof-of-concept SVG assembler to generate a self-contained animated SVG file from multiple still SVG files with CSS keyframes animation to play frames in sequence.
