Chocolatey: imagemagick

ImageMagick is a software suite to create, edit, compose, or convert bitmap images.

It's pretty fucking magickal.

TODO - I didn't note the actual commands I use

2016-04-27 - 7.0.0-0-portable-Q16-x64 ∞

After some googling with the previous version, I grabbed a portable version from ftp://ftp.imagemagick.org/pub/ImageMagick/binaries/

Well.. it works.

misadventure - But good fucking luck trying to make an image slideshow which is imported into Open Broadcaster Software with transparency / chroma key. It's impossible. Antialiasing, fuzzing, feathering, colours, blah blah.. fuck it .. fuck it all!

2016-04-27 - 6.9.3-8-Q16-x64 ∞

Installed with Chocolatey with:

chocolatey.exe install imagemagick

I had to say yes to a bunch of prompts.

Comes with FFmpeg.

convert.exe -delay 1 *.png -loop 0 foo.mpg

output

I uninstalled it, but it uninstalled one package... where its installation was three. Sigh.

imagemagick-6.8.6_10-i486-1

This came with Slackware.

2016-03-26 - 8:6.7.7.10-6ubuntu3 ∞

Although the version I have installed is 8:6.7.7.10-6ubuntu3, I haven't used this in a long time. My originally-installed version may well be different than this currently-installed version.

(no notes were recorded)

This probably came with Lubuntu.
