Public Member Functions | |
NullTextureTarget (NullRenderer &owner) | |
Constructor. | |
virtual | ~NullTextureTarget () |
Destructor. | |
bool | isImageryCache () const |
Return whether the RenderTarget is an implementation that caches actual rendered imagery. | |
void | clear () |
Clear the surface of the underlying texture. | |
Texture & | getTexture () const |
Return a pointer to the CEGUI::Texture that the TextureTarget is using. | |
void | declareRenderSize (const Sizef &sz) |
Used to declare to the TextureTarget the largest size, in pixels, of the next set of incoming rendering operations. | |
bool | isRenderingInverted () const |
Return whether rendering done on the target texture is inverted in relation to regular textures. | |
Static Protected Member Functions | |
static String | generateTextureName () |
helper to generate unique texture names | |
Protected Attributes | |
NullTexture * | d_CEGUITexture |
This wraps d_texture so it can be used by the core CEGUI lib. | |
Static Protected Attributes | |
static uint | s_textureNumber |
static data used for creating texture names | |
static const float | DEFAULT_SIZE |
default / initial size for the underlying texture. |
CEGUI::TextureTarget implementation for the Null engine.
void CEGUI::NullTextureTarget::declareRenderSize | ( | const Sizef & | sz | ) | [virtual] |
Used to declare to the TextureTarget the largest size, in pixels, of the next set of incoming rendering operations.
sz | Size object describing the largest area that will be rendererd in the next batch of rendering operations. |
InvalidRequestException | May be thrown if the TextureTarget would not be able to handle the operations rendering content of the given size. |
Implements CEGUI::TextureTarget.
Texture& CEGUI::NullTextureTarget::getTexture | ( | ) | const [virtual] |
Return a pointer to the CEGUI::Texture that the TextureTarget is using.
Implements CEGUI::TextureTarget.
bool CEGUI::NullTextureTarget::isImageryCache | ( | ) | const [virtual] |
Return whether the RenderTarget is an implementation that caches actual rendered imagery.
Typically it is expected that texture based RenderTargets would return true in response to this call. Other types of RenderTarget, like view port based targets, will more likely return false.
Reimplemented from CEGUI::NullRenderTarget< TextureTarget >.
bool CEGUI::NullTextureTarget::isRenderingInverted | ( | ) | const [virtual] |
Return whether rendering done on the target texture is inverted in relation to regular textures.
This is intended to be used when generating geometry for rendering the TextureTarget onto another surface.
