Hi,
I just tried to save coffeewheel (https://github.com/armish/coffeewheel) as gif file.
animation needs ImageMagick?
Thanks
sh: convert: command not found
Error in cmd.fun(sprintf("%s --version", convert), intern = TRUE) :
error in running command
I cannot find ImageMagick with convert = 'convert'
Warning in run(timeoutMs) :
Please install ImageMagick first or put its bin path into the system PATH variable
Warning in run(timeoutMs) :
path[1]="animation.gif": No such file or directory
