Theoretical production of Windows boot animation

First contact with Windows boot animation is 2012, then the version number of the Rubik's Cube is still 3.12, the Rubik's cube inside a cool crazy bully is to replace the Windows 7 boot animation. At first I was in the IT home forum to download the start-up animation, over time, the initiation of their own production of the idea of the boot animation. After many inquiries, finally understand the Rubik's cube of the boot animation. bmp file Mystery. The original user made the. bmp file is composed of 105 independent 200*200 pixels of the picture, each picture is a frame, 105 pictures such as the order of the Mosaic support. bmp file. (So we can also figure out a qualified boot animation file size is 200*21000) Windows boot animation has a certain playing law, that is, the first 60 frames play sequentially, after 60 frames, that is, 61-105 frames will be performed loop playback.

Windows 7 Boot Animation

After knowing how the Windows boot animation works, we know how to make a boot animation--a picture of 105 images 200*200 pixels together into a 200*21000 pixel image.　　You can get a GIF animated image from the Internet (or you can intercept the video), save every frame of it and change the size, and use Photoshop or other software to make the boot animation. It is worth mentioning that when you create your own animation through the Rubik's Cube, the power on the display of the pattern is another landscape-the image is stretched, especially when your boot pattern is a circle. Here I need to popularize the display of the size of the problem, the general widescreen LCD screen (notebook or some desktop) size is 16:9, and then Pu size 4:3, the following is a picture of two 200*200: (one frame in the animation)

Figure A figure II
　　

If I were to tell you that these two pictures were in the same way they were in the boot animation, would you believe that? The fact is that, figure one is 16:9 of the size, and figure two is 4:3 of the size, where two pictures of the boot animation in the corresponding size of the display is exactly the same, the display is the image of the two look. So you might ask, how do you achieve mutual conversions between two sizes? The answer is simple, and we can do it easily with Photoshop. Here is the 4:3 conversion to 16:9 method, 16:9 conversion 4:3 do the opposite.

STEP 1 opens the. bmp image with PS
STEP 2 Modify image size (alt+ctrl+i) and canvas size (alt+ctrl+c)


STEP 3 fill blank for black
STEP 4 Save
