I created a Music Notes v2 EPUB (attached).

It includes a few more test cases:

• No Embedded Font
• Embedded Font
• Transparent GIFs
  
  • I generated all 4 Musical Notes at 300px height using Inkscape.
• Transparent PNGs
  
  • In the long ago past, KindleGen converted PNG alphas -> black background.
    
  • Also, depending on how the PNGs were optimized, I ran across KindleGen outputting a giant black box. Who knows what regressions could potentially be introduced in later versions, so I like to test stuff like this every so often.
• GIFs (White Background)
• PNGs (White Background)

Night Mode

So, I open up my book. White background black text, who could read any other way?



My book looks PERFECT!

It is getting a little late and the white is starting to blind me. Let me flick on Night Mode:



Oh crap, where did those musical notes go? Well let me go to the non-transparent version:



Woof, I can't even tell what those notes are. Now let me just swap over to the Embedded Font:



Beautiful!

Colors, Colors, and More Colors

Now, forgive me ahead of time for these abominations, but I wanted to show how it would look if a reader picked a Green background + Red text:



I love to read in Red text, but those stupid musical notes are ruining my perfect look! As you can see, the Transparent/Non-Transparent Images have some serious mismatches.

One of the things you have to keep in mind when you create these ebooks is that people will be reading on all different types of settings, and you should make sure your book does great in most/all of these situations. Night Mode and Color are two of the most used settings (on non-e-ink devices).

One symbol? One symbol? The entire fate of the world is in the balance here!

The same issues still apply (Text-to-Speech problems, Search problems, Font Color problems, [...]), only different in scale.
