"""Draws MiniABS's PNG icons for ldpi (Galaxy Mini), mdpi and hdpi.
|
|
|
|
The launcher icon (res/drawable-*/ic_launcher.png) comes from the supplied
|
|
Audiobookshelf icon pack and is not generated here. The notification icon is
|
|
cut out of that same artwork (art/icon_master_512.png): the white headphones
|
|
and equalizer become a white silhouette, as Android 2.3's status bar expects.
|
|
|
|
Android 2.x has no vector drawables, so the player icons are rendered at 4x and
|
|
downsampled for smooth edges.
