Mach Banding images in Android
<p>I used a linear gradient image for a background and in Photoshop (and everything else) it looks nice and smooth but when I displayed it in the emulator is was banded!   What's worse, it's banded on my actual phone - a Droid Incredible.    I'm running 2.2 both in emulation and on the phone.</p>

<p>Here's a sample -  original on the left, Android'ed version on the right:  <a href="http://pnart.com/temp/AndroidMach.jpg" rel="nofollow">http://pnart.com/temp/AndroidMach.jpg</a></p>

<p>This has the appearance of Android imposing some bit-depth limitation.   What's going on and how do I fix it?</p>

<p>Thanks in advance!</p>
