jokeyrhyme: The issue isn't that it's off-center, but rather than the sun textures aren't perfectly round. I drove myself crazy trying to eliminate the wobble, only to figure out that it couldn't be eliminated.
The minimap shape is defined by a mask texture. It's unique to the minimap, unfortunately.
That said, any image can be used as a minimap mask. White areas are full color, transparent are transparent. Create a PNG of your favorite shape, convert it to a BLP, and it can be a minimap mask.
Edit: Also in this update are button dragging shapes. You can get the buttons to follow any shape you want. There's circle/square/diamond in so far, and other shapes would be trivial to add. Maybe I should add triangle/hexagon masks?
1) Create a directory in Interface\Addons called "SexyMap_Custom" or something like that. (A separate directory makes sure it'll never get deleted by an updater)
2) Put your textures into that directory. They should be in TGA or BLP format. I find it's easiest to use BLPConverter - just create PNGs, then drag them onto BLPConverter's exe, and it spits out a BLP file for you. Note that files have to have sides that are a power of 2 (64x64, 128x128, etc), and can't be bigger than 512x512.
3) Put in the path to your texture. For example, if you had Interface\Addons\SexyMap_Custom\mytexture.blp, then in SexyMap, you'd enter:
SexyMap has lots of tricks. She's very flexible, and can go where you need her to. She's also very classy - by default, she won't wear any gaudy buttons if you don't want her to. But don't worry, they're still there. Just touch her gently with your mouse and all her buttons are yours to peruse.
She comes with a very robust wardrobe, and of course, is always open to trying on new things. Here are some examples of her outfits:
You can move her friends around, too. Is Mr. DurabilityFrame getting in your way too much? Just stick him off in the corner and he'll stay put.
She can do quite a bit more, but in short, it's a minimap mod with class. It's sleek. It's sexy. And it has a great personality to boot.
