Reading a recent server setup guide I saw the suggestion to use
apt-get install php5-ming to install Ming – as a (suggested) module that WordPress would like to have.
so what is MING ?
First of all: Ming is not an acronym. Ming is an open-source (LGPL) library which allows you to create SWF (“Flash”) format movies. Ming supports almost all of Flash 4’s features, including: shapes, gradients, bitmaps (pngs and jpegs), morphs (“shape tweens”), text, buttons, actions, sprites (“movie clips”), streaming mp3, and color transforms –the only thing that’s missing is sound events.
Note that all values specifying length, distance, size, etc. are in “twips”, twenty units per pixel. That’s pretty much arbitrary, though, since the player scales the movie to whatever pixel size is specified in the embed/object tag, or the entire frame if not embedded.
More information about ming is available in the PHP documentation
