First things first: This addon is a plug-in skin pack for Minimap Button Frame. If you don't have MBF installed, this addon will just waste 192 KB's of space on your hard drive.
Now updated for 6.2.0 Fury of Hellfire!!
A while ago I made a Button Facade (now Masque) skin called "ClassButtons" using square, class colored buttons for the action bars. I made it to (kind of) compliment the class colored MBF skins I had already released, and which Bachlott (the author of MBF) has since graciously included within MBF itself. It always kind of bugged me, though, that I couldn't make a round Button Facade skin that was "crisp" enough to suit me. I still can't. So I made a square class colored skin pack for MBF instead. It's not perfect, but it looks pretty good to my aging eyes.
Please do not post in the comments section that the skins are not "pixel perfect". They're probably not. I changed all of the graphics to Blizzards native .blp format (which shrank the physical file size ) and added: A) The gloss layer graphics that I put up for Beta test here, and B) The Monk class.
If you choose to install this plug-in, you can access the skins via the Minimap Button Frame options and they will show up in the skin drop down as "s<Class>". One for each of the eleven current classes.
Anyway, I hope you enjoy this little plug-in for MBF.
Change Log for MinimapButtonFrame_sClassButtons
v3.1.0 TOC bump for 6.2.0 Fury of Hellfire.
v3.0.0 TOC bump for 6.1.0 The Adventure Continues.
v2.0.5 TOC bump for 6.0.2 The Iron Tide.
v2.0.4 TOC bump for 5.4 Siege of Orgrimmar.
v2.0.3 TOC bump for 5.3 Escalation.
v2.0.2 TOC bump for 5.2 The Thunder King.
v2.0.1 TOC (.toc file) bump for 5.1 Landfall.
v2.0 Added "Monk" class for MoP. Changed all of the graphics to the BLP graphics format. This does two things: It's the native graphics format for WoW, and the physical file size is smaller so the addon will take up less space on your hard drive.
v1.3a Changed graphics to Blizzard native .blp format and added a "gloss" layer to them
v1.3 Uploaded 12/3/2011 around 6:00 PM-ish PA time.
TOC bump for 4.3. Nothing else is changed.
v1.2 Uploaded around 8:30PM-ish PA time
TOC bump for 4.2. That's it, folks.
v1.1 Uploaded: 4/26/2011 Around 11:00 PM-ish PA time.
TOC bump for the 4.1 patch and added better, slightly larger, graphics. I could see a very tiny bit of the Blizzard Calendar button outside of the MBF button surround, and it just bugged the bejesus out of me. So, I made these graphics.
v1.0 - Initial release 4 / 16 / 2011 10:30-ish, South Eastern PA time.
