What is simplest process to get ImageMagick 7 with PNG support on Ubuntu?
Solution 1:
I highly recommend ImageMagick Easy Install (IMEI):
https://github.com/SoftCreatR/imei/
It tracks down all the source/development libraries needed for the additional ImageMagick "delegates" (image formats in IM-speak). Plus, it can also incrementally update your local install from newer source after the initial installation.
Installation steps as of now:
git clone https://github.com/SoftCreatR/imei
cd imei
sudo ./imei.sh
