[C#] How to readout wow Minimap

[Holico]

Hey guys,
im working on a wow Radar and its working now, but i want it better than it is atm.
It would be great if i could put the minimap in the background, so it looks like i have a satalite picture.

Can anyone explain to me how to get Map data? or link me a good tutorial?

1. Open all MPQs (or extract them)
2. Goto /maps/minimaps/[continent]/
3. Open the blp Files you need.

The format of the BLP-files is mapY_X.blp where X and Y is the adt position on a 64 by 64 grid. To get your current ADT position you can do this (copied from ADT/v18 - WoWDev)

<BlockY> - obtained with the following formula: floor((32 - (y / 533.33333)))
<BlockX> - obtained with the following formula: floor((32 - (x / 533.33333)))

BLP files are textures. I have written a BLP Lib. You can use it to open, display and convert BLP in C#.

For instances and interior (wmo - buildings, caves and such stuff) its a bit harder to get a minimap. I can't help you on this, since currently I don't know how to build the i.e. ragefire minimap in code
Eastern Kingdoms, Kalimdor, Northrend and Outlands on the other hand is realy easy.

For other maps, just keep a list of which map ids match up with which blp files, and read the map id from memory. I don't understand why anyone would bother with interior (being indoors, etc.).

because instances like ragefire don't have a adt based minimap
And for the other maps: You don't need to keep a list. You can read it out of the second field in Map.dbc (internal_name)

Whoa.
First of all thanks for the great help.
ill try it and rep you afterwards, hopefully i get it to work.
I will use my radar mainly for pvp, so there is no realy need for inbuilding maps i think.
ill start now with the work, report back if i finished it, or dont get it to work
