Detailed Description

Class for accessing images in ALLEGRO_BITMAP format and low level drawing.

The store ensures that only one copy of identical images are created. This is done through a map, that caches the images that have already been requested. If an uncached image is requested, it is added to the cache before being returned. The store provides an enumerated type, Image, for other classes to reference which image should represent the object on the screen.

All images are square, to allow easy rotation and placement on the screen.

Constructor & Destructor Documentation

BitmapStore::BitmapStore ( unsigned int blockWidth )

Constructor for creating a BitmapStore with a set image size.

Parameters:

[in] blockWidth The width (and height) of an image returned by the store in pixels.

Definition at line 3 of file BitmapStore.cpp.

BitmapStore::~BitmapStore ( )

Destructor for clearing cache.

Definition at line 14 of file BitmapStore.cpp.

BitmapStore::BitmapStore ( const BitmapStore & ref ) [private]

Unimplemented copy constructor, prevents copying of BitmapStore objects.

Copying a BitmapStore is unneccesary as there should only be a single BitmapStore object.
