WoW:API Frame SetBackdrop

Syntax

SetBackdrop({bgFile = "bgFile", edgeFile = "edgeFile", tile = false, tileSize = 0, edgeSize = 32, insets = { left = 0, right = 0, top = 0, bottom = 0 }})

Using 'nil' as the only parameter will remove the backdrop on the indicated frame.

Example

MinimapCluster:SetBackdrop({bgFile = "Interface\Tooltips\UI-Tooltip-Background", edgeFile = "Interface\Tooltips\UI-Tooltip-Border", tile = true, tileSize = 32, edgeSize = 32, insets = { left = 0, right = 0, top = 0, bottom = 0 }}) --Nathanmx 03:23, 1 Oct 2005 (EDT)

Note that it looks pretty retarded without any insets. And if you do not escape the backslashes, it will not work at all. Just use slashes, geez.
