Texture & createTexture(const CEGUI::String &name)
Create a 'null' Texture object.
void destroyTexture(Texture &texture)
Destroy a Texture object that was previously created by calling the createTexture functions.
Implementation of CEGUI::Texture interface using DirectFB.

IDirectFB & d_directfb
DirectFB interface we were given when constructed.
Definition RendererModules/DirectFB/Texture.h:79
DirectFBTexture(IDirectFB &directfb, const String &name)
Basic constructor.
IDirectFBSurface * getDirectFBSurface() const
Return a pointer to the IDirectFBSurface this texture represents.
const Sizef & getSize() const

bool isPixelFormatSupported(const PixelFormat fmt) const
Return whether the specified pixel format is supported by the system for the CEGUI::Texture implement...
DirectFBTexture(IDirectFB &directfb, const String &name, const String &filename, const String &resourceGroup)
Construct texture from file.
const Sizef & getOriginalDataSize() const

~DirectFBTexture()
Destructor.
const String & getName() const
Returns the name given to the texture when it was created.
void loadFromMemory(const void *buffer, const Sizef &buffer_size, PixelFormat pixel_format)
Loads (copies) an image in memory into the texture. The texture is resized as required to hold the im...
