To the west of the 5 skeleton warrior room, a chamber full of bats appeared, and the doorway slammed shut behind me. I had a key, I could have ignored them, but I wanted to know what would reveal itself if they were all slain. It cost me dear health, but the chamber door opened.
I was using gifBrewery because I knew how to resize a gif with it quickly. When I’m not cropping a to an artistic subset of the image, doing the whole process with the handful of lines of ImageMagick needs goes much more quickly.
| mogrify *.png -gravity South -crop 1200×860+0+0 +repage *.png | |
| convert -delay 50 *.png -colors 256 -loop 0 toT5_50.gif | |
| convert toT5_50.gif -resize 310×215 tot5_50_tumb.gif | |
| #Also could have used percentage resize: | |
| #convert toT5_50.gif -resize 25% -colors 256 toT5_50_tumb.gif |
Notice the use of mogrify to do the batch process at the beginning… That was the tricky part.
