One of the new features in the 1.4 beta series of Minecraft releases is the raster-based logo. Today I will be explaining briefly the details of modifying this file yourself to create your own logo.
As you can see from my own site logo, I've already produced a slick new mclogo.png graphic for the game, which will be incorporated into the next release of PepBasic. Here is a zoomed version so you can see the painstaking pixel-by-pixel detail that went into creating this version:
There are just a few things to remember when editing the image. First off, the mclogo.png resource splits the logo into 2 chunks separated by a 1 pixel vertical space between them, which are joined in the game. Each chunk has a different width which means they do not join at a centered position. The first piece has a dimension of 155x44 while the second piece is 119x44, and together this creates a 274x44 sized logo. Half of 274 is 137, which is center, so if you're going to create a new logo you will want to keep this in mind. 274x44 is presumably the maximum space you have within which to work. I have not tested higher resolution mclogo.png files, so I appreciate any feedback you can report on that.
Also, the mclogo.png file uses black for the background/transparency, and a near-black color for the lettering. While it is a PNG file, it uses an indexed palette and assigns a single color to transparency, like a GIF would do. So keep this in mind! Of course you can change the background color to whatever you want and then make it transparent. It's possible that the logo image would also accept an alpha channel mask, but I have not tested this yet. I'm a bit of a nut when it comes to image compression, and would suggest using the transparent color solution rather than an alpha mask, since this makes the total file size smaller. The only time you would want an alpha mask in this situation is if you were designing a logo with semi-transparent elements, and I can only assume with reasonable certainty that the program would render this without problems.
And that's it! I hope I've answered any questions you have about this particular Minecraft image resource.
Lastly, here are a few more samples of my design set against the original for comparison:
