Detailed Description

A singleton class for managing allocated SDL_Surface* returned from SDL_LoadBMP(). Use this class in order to avoid loading the same image twice.

Notes for usage:

• Call ImageManager::destroy() to ensure proper reallocation of all memory
• Don't explicitly free images in the ImageManager with SDL_FreeSurface(), instead use the freeBMP() method, so the class knows not to refer to removed images

Read this article if you want information on singletons Singleton Texture Manager . The article covers using textures in OpenGL but the concept is the same.

Definition at line 110 of file ImageManager.cpp.

void ImageManager::destroy (    )  [static]

Destroys sole instance of ImageManager class, deallocating all memory and freeing all surfaces Definition at line 85 of file ImageManager.cpp.

void ImageManager::freeAll (    )

Frees all stored surfaces, but does not delete instance of class Definition at line 89 of file ImageManager.cpp.

void ImageManager::freeBMP (  SDL_Surface *    surf )

Frees single image pointed by surf Definition at line 61 of file ImageManager.cpp.

void ImageManager::freeBMP (  const string &    str )

Frees single image referred to by str Definition at line 72 of file ImageManager.cpp.

SDL_Surface * ImageManager::getImage (  const string &    str )

Returns image stored by ImageManager with given filename. If fast, repeated access is needed, instead save the surface after a single call Parameters: str  string specifying image to return Returns: image specified by given index Definition at line 39 of file ImageManager.cpp.
