MEL: How to check if an image has an alpha channel

[sparaig]

Hi people
Does anyone know of a command or a way to query if an image file has an alpha channel or not?

what i want to do is something like:
if (/*THE FILE HAS AN ALPHA CHANNEL*/) connectAttr -f ($fileNode + ".outTransparency") ($lambert + ".transparency");
else //dont do anything
Any ideas?

Check the fileHasAlpha attribute:

fileHasAlpha (fha) bool false
Is set to true if the file on disk has an alpha channel for which one or more pixels have alpha != 1, false otherwise.
