create decent gif infographics from impress presentations

Postby figlfdev » Wed Jun 01, 2016 6:06 am

no one likes powerpoint and its ilk, but ive been working on a short coding "textbook" and my friend who hates to read says he doesnt want to read longform.

since he has enough familiarity with code (but not really enough to do more than find his way around the command line) i thought id make index cards. but i didnt have index cards, so i used paper plates (i have tons.)

then i started looking for the best way to do "paper plate" index cards digitally, which is when i pulled out impress-- a tool i almost never use.

it can export to pdf or do a page to an image, but the export to images plugin was buggy, so i did this instead using inkscape and pdf2svg:

Code: Select all
for x in $(seq 1 12) ; do pdf2svg slides.pdf slide$x.svg $x ; inkscape -z -e slide$x.png -w 502 -h 376 slide$x.svg ; convert slide$x.png slide$x.gif ; done


so this is exporting each page to svg, png and gif. and theyre all fairly nice looking.

convert can stitch them all together into an "infographic" like this:

Code: Select all
convert slide1.gif slide2.gif slide3.gif slide4.gif slide5.gif slide6.gif slide7.gif slide8.gif slide9.gif slide10.gif slide11.gif slide12.gif -append out.gif


if you use -append it is vertical, +append is horizontal.
