Helper class for building and displaying image animations for GIF files or a set of still bitmaps (png, gif,

led - LEDMatrix instance
plist - The dictionary loaded from the playlist.json file.
offset - X,Y tuple coordinates at which to place the top-left corner of the image
bgcolor - RGB tuple color to replace any transparent pixels with. Avoids transparent showing as black
brightness - Brightness value (0-255) to scale the image by. Otherwise uses master brightness at the time of
instantiation.
Key features of the playlist:
1) It's JSON. Example:
{
"1": {
"file": "./anim/matrix.gif",
"duration_s": 30,
"frame_time_ms": 150
},
"2": {
"file": "./anim/spinning balls.gif",
"duration_s": 30,
"frame_time_ms": 50
},
"3": {
"file": "water.gif",
"duration_s": 30
}
}
2) Each item is indexed with something sortable.
3) Each item contains the following attributes:
file: path to the file. absolute path is tried first. If not found, searches in ./anim and ./stills
duration_s: The duration in seconds that you wish to display the image or animation
frame_time_ms: The FPS, but in milliseconds
Soon:
fade_in:
