<h1>Maps</h1>
|

<p>Maps represent a geographical image in a PIXI.Application. Preferably in a MapApp to have more convenient methods

|
to

handle the maps.</p>
|
|

|
<h2>Cover Test</h2>
|
|
<p>Usually maps should cover the whole app, or a window inside the app. Therefore they support a cover option.

This option allows the

<h1>Movement</h1>
|
|
<p>
|
|
Its crucial to focus certain points in a map application. The following tests the behavioud of maps inside a
|
|
mapapp and maps
|
|
inside of windows.
|
|
</p>
|
|
|
|
</ul>
|
|
<h2>Map Frame</h2>
|
|
<p>
|
|
The map's frame specifies the stage of the map. When moving to the focus point normally, the map focuses in the
|
|
center, the
|
|
frame defines the new area, the map will be centered in. This is important when trying to mask a map.
