Build

Note: This is tailored for 768x1280 screens.

Drop android.png into MOSH.
Use the controls on the site and set:

• Slices: slices = 45, offset = 0.008
• BadTV: thick = 2.9, fine = 2.3
• RGB Shift: amount = 0.008

Resize your browser so the <canvas> element is 384 x 640.

Paste into console:

var captures = [];

// create 40 screenshots with a delay of 100ms
new Array(40).join(",").split(",").forEach(function(a, i) {
  setTimeout(function() {
    captures.push(canvas.toDataURL());
  }, i * 100);
});

// wait for captures to finish
setTimeout(function(){

  // strip out URL parts
  for (var i = 0; i < captures.length; i++) {
    captures[i] = captures[i].split(",")[1];
  }

  // trailing new line
  captures.push("");

  // create new file
  var blob = new Blob([captures.join("\n")], {type : 'application/data'});

  // download
  window.open(URL.createObjectURL(blob));
}, 50*100);

Download and save the file as base64-images.txt.

Now run build.sh and check for extra images that can be removed to make the animation loop seamlessly.

Create the animation archive without compression:

zip -r0 bootanimation.zip desc.txt part0

Replace the existing boot animation:

adb root
adb remount
adb shell 'mv -iv /system/media/bootanimation.zip{,.bak}'
adb push -p bootanimation.zip /system/media/bootanimation.zip

That's it. Reboot to see the animation!
