Member Function Documentation

virtual void Ogre::Texture::blitImage (  const Image &    src, const Image::Rect    imgRect, const Image::Rect    texRect )  [inline, virtual, inherited]

Blits a rect from an image to the texture. Parameters: src  The image with the source data. imgRect  The data rect to be copied from the image. texRect  The rect in which to copy the data in the texture. Reimplemented in Ogre::D3DTexture.

void Ogre::SDLTexture::blitToTexture (  const Image &    src, unsigned    uStartX, unsigned    uStartY )  [virtual]

Blits the contents of src on the texture. Deprecated: This feature is superseded by the blitImage function. Parameters: src  the image with the source data Implements Ogre::Texture.

virtual void Ogre::Texture::copyToTexture (  Texture *    target )  [inline, virtual, inherited]

Copies (and maybe scales to fit) the contents of this texture to another texture. Reimplemented in Ogre::D3DTexture.

virtual void Ogre::Resource::destroy (  void    )  [inline, virtual, inherited]

A method to make the resource delete itself. Note: This exists because Resource objects could be created in other processes, and they need to be destroyed in the process that created them.

void Ogre::Texture::enable32Bit (  bool    setting = true )  [inline, inherited]

void Ogre::SDLTexture::generateMipMaps (  uchar *    data )  [protected]

std::pair< uint, uint > Ogre::Texture::getDimensions (    )  [inline, inherited]

Returns both the width and height of the texture.

virtual PixelFormat Ogre::Texture::getFormat (    )  const [inline, virtual, inherited]

Returns the pixel format for the texture surface.

float Ogre::Texture::getGamma (  void    )  [inline, inherited]

Returns the gamma adjustment factor applied to this texture.

GLuint Ogre::SDLTexture::getGLID (    )  const [inline]

unsigned int Ogre::Texture::getHeight (  void    )  [inline, inherited]

Returns the height of the texture.

time_t Ogre::Resource::getLastAccess (  void    )  const [inline, inherited]

Gets the last time the resource was 'touched'.

const String& Ogre::Resource::getName (  void    )  const [inline, inherited]

Gets resource name. Reimplemented in Ogre::Material.

unsigned short Ogre::Texture::getNumMipMaps (  void    )  [inline, inherited]

Gets the number of mipmaps to be used for this texture.

virtual size_t Ogre::Resource::getSize (  void    )  [inline, virtual, inherited]

Retrieves info about the size of the resource.

TextureUsage Ogre::Texture::getUsage (    )  const [inline, inherited]

unsigned int Ogre::Texture::getWidth (  void    )  [inline, inherited]

Returns the width of the texture.

virtual bool Ogre::Texture::hasAlpha (  void    )  [inline, virtual, inherited]

Returns true if the texture has an alpha layer.

bool Ogre::Resource::isLoaded (  void    )  const [inline, inherited]

Returns true if the Resource has been loaded, false otherwise.

void Ogre::SDLTexture::load (    )  [virtual]

Loads the resource, if it is not already. Implements Ogre::Resource.

void Ogre::SDLTexture::loadImage (  const Image &    img )  [virtual]

Loads the data from an image. Implements Ogre::Texture.

void Ogre::Texture::setGamma (  float    g )  [inline, inherited]

Sets the gamma adjustment factor applied to this texture. Note: Must be called before any 'load' method.

void Ogre::Texture::setNumMipMaps (  unsigned short    num )  [inline, inherited]

Sets the number of mipmaps to be used for this texture. Note: Must be set before calling any 'load' method.

void Ogre::Resource::touch (  void    )  [inline, inherited]

'Touches' the resource to indicate it has been used.

void Ogre::SDLTexture::unload (  void    )  [virtual]

Unloads the resource, but retains data to recreate. Reimplemented from Ogre::Resource.
