Today I finally understood this blog post (the one I mentioned in the last post) or at least found a way to use it in my own game.
Let's resume how I managed the heightmap graphix so far.
For each of the edges and corners, I added 2^n to a byte value to find out which tile there has to be. Then I put that value in a switch statement to apply the appropriate graphic. In the end, that looked something like this:
case 11:
case 15:
case 43:
case 47:
Now that's not very efficient... But now I got how it can be down easier. Yay :D So I changed some function here, some other thingy there and it worked w/o any bug. Hooray for me! Now I first check the edges: if there's a different height, I'll have to apply some graphics, so I don't need to check the corners. If the height is the same, I check the corners. The calculation for the cases is pretty much the same, but now I only need 32 cases, not up to 256. All that's left to do is to clean up the code and get rid of all those unnecessary cases now.
The next thing to do after that will be the transition between the tile types.
Oh, and I need better graphics. Definitely...
Cheerio,

PS: here are some screenshots of the finished height map:
