"""Media accessors
|
||||
|
||||
Most media accessor __init__s take an ORM object from the pokedex package.
|
||||
Their various methods take a number of arguments specifying exactly which
|
||||
file you want (such as the female sprite, backsprite, etc.).
|
||||
ValueError is raised when the specified file cannot be found.
|
||||
|
||||
The accessors use fallbacks: for example Bulbasaur's males and females look the
|
||||
same, so if you request Bulbasaur's female sprite, it will give you the common
|
||||
image. Or for a Pokemon without individual form sprites, you will get the
|
||||
common base sprite. Or for versions witout shiny Pokemon, you will always
|
||||
get the non-shiny version (that's how shiny Pokemon looked there!).
|
||||
However arguments such as `animated` don't use fallbacks.
|
||||
You can set `strict` to True to disable these fallbacks and cause ValueError
|
||||
to be raised when the exact specific file you asked for is not found. This is
|
||||
useful for listing non-duplicate sprites, for example.
|
||||
|
||||
Use keyword arguments when calling the media-getting methods, unless noted
|
||||
otherwise.
|
||||
|
||||
The returned "file" objects have useful attributes like relative_path,
|
||||
path, and open().
|
||||
|
||||
All images are in the PNG format, except animations (GIF). All sounds are OGGs.
