Note: LibMapData-1.0 is unmaintained, a suggested replacement library is HereBeDragons-1.0

Small library that provides mapfile data. it include width,height, upper left x,y and lower right x,y. This data includes multi-floor maps such as the new instances.

API Documentation

To get the mapfile names use GetMapInfo() on the current map. Filenames are constant across localizations.

Sample usage:

     mapfiles = LibStub("LibMapData-1.0"); 
     -- get the size of Coth defaulting to the first floor size
     local width,height = mapfiles:MapArea('CoTStratholme')
     -- get the size of the 8th floor of icc 
     width,height = mapfiles:MapArea('IcecrownCitadel',8) 
     -- get the size of the Arati mapfile.
     width,height = mapfiles:MapArea('Arathi')

The floors are optional and if a given floor is not found 0,0 will be returned. This lib came about as a result of several addons needing the data, and simply copying and pasting them in each copy occupies around 44k of memory.

LibMapData now supports Mapchanged callback event. Sample usage:

mapfiles = LibStub("LibMapData-1.0"); 
mapfiles:RegisterCallback("MapChanged",function(event,map,floor,w,h) print("Map is now " end

    I'll update to reflect mysticalos, the dbc data is way wrong I'm nit sure why. The dbc files only shows 2 floors period not 3 but the map drop down shows 3 floors. I wasn't able to get into the zone myself either last night I was using data provided by others as to size

    firelands sizes are still wrong, the blizz api also reported wrong sizes sigh i used /dumb GetMapInfo() and those are sizes it reportegd and i plugged into dbm but they are way way WAY off in areas 2 and 3 still.

    here are real ones for area 1 and 2 at least verified in game using actual calculations and mage blink (20 yards)
    oldschool methods!

        1, 1587.0, 1058.0,     -- The Firelands (this one is as cose to accurate as i could get it
        2, 1440.0, 960)        -- Sulfuron Keep (looks like this one actually was right)

    I could not find area 3 yet cause i cannot access it in game until. maybe that's the one that's 375.0, 250.0? that's what i'm gonna assume for now. WTF is up with blizzards invalid sizes in data files AND GetMapInfo() api anyways?

    i updated the code to now cache, need to test before i drop it in, in either case there are no errors in game any more

    It should be fine, i just forgot to tag it so plugins got the data.

    Perhaps you could cache the fact that a message has been displayed and avoid displaying it more than once. I think that would be an improvement.

    	setmetatable(mapData, { __index = function(t, k) if k then DEFAULT_CHAT_FRAME:AddMessage("LibMapData-1.0 is missing data for "..k) end; return emptyMaps end })
    	setmetatable(idToMap, { __index = function(t, k) if k then DEFAULT_CHAT_FRAME:AddMessage("LibMapData-1.0 is missing data for area id "..k) end; return k end})
    	setmetatable(mapToLocal, { __index = function(t,k) if k then DEFAULT_CHAT_FRAME:AddMessage("LibMapData-1.0 is missing localized data for "..k) end; return k end})

    There has got to be a better way to handle missing data than spamming chat with thousands of messages. Please find it.

    Missing data for Sethekk Halls. Getting spammed with "LibMapData-1.0 is missing data for 723" as soon as I zone in.
