API Frame SetBackdrop

Frame: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.

Arguments

 * bgFile:String - Which texture file to use as frame background (.blp or .tga format)
 * edgeFile:String- Which texture file to use as frame edge blp or .tga format)
 * tile:Boolean - whether background texture is tiled or streched
 * tileSize:Number - Control how large each copy of the bgFile becomes on-screen
 * edgeSize:Number - Control how large each copy of the edgeFile becomes on-screen (i.e. border thickness and corner size)
 * insets:4 x Number - Controls how far into the frame the background will be drawn (use higher values the thicker the edges are)

Example
MinimapCluster:SetBackdrop({bgFile = "Interface/Tooltips/UI-Tooltip-Background",                                             edgeFile = "Interface/Tooltips/UI-Tooltip-Border",                                              tile = true, tileSize = 16, edgeSize = 16,                                              insets = { left = 4, right = 4, top = 4, bottom = 4 }}); MinimapCluster:SetBackdropColor(0,0,0,1);
