this is all gravy (good) except that, It does not need to be a part of any toolset IMHO. What about command-line batch processing, then noggit etc could integrate it via a simple gui and the apps development would remin seperate.One of the things I have noticed that worries me a little is that everyone wants Noggit, Yias, Taliis etc to be an all in one toolset like blizzard probably uses but it does not have to be so nd would probably benefit from a more compartmentalised approach. Using win32 API it is entirely possible to capture a form by name and put it inside a picturebox instead of using the start-menu. I know it's just a lot of I want... but I think I may even be able to amble together this myself with an empty adt and just have the app edit the height data.Also wow 272pixels is miniscule, the data set I'm looking at is like 5000x4000 pixels lol, so probably a bit more than wow can handle, anyway, I'll see if I can code up a little demo app (although it may be for 2.x.x initially)
