Apparently the ImageMagick -depth option is per channel (color / alpha), not per pixel. It’s not very well explained in the documentation. We had some code written by a former developer sometime before I started (over six years ago) using -depth 24. We were finding that PNG’s that the code operated on were very large, yet nobody noticed until this week that a simple two character change (24 to 8) could fix it.
