Public Member Functions | |
void | setDirect3DTexture (ID3D10Texture2D *tex) |
set the D3D10 texture that this Texture is based on to the specified texture. | |
ID3D10Texture2D * | getDirect3DTexture () const |
Return the internal D3D10 texture used by this Texture object. | |
ID3D10ShaderResourceView * | getDirect3DShaderResourceView () const |
Return the internal D3D10 shader resource view for the texture. | |
void | setOriginalDataSize (const Size &sz) |
Sets what the texture should consider as the original data size. | |
const Size & | getSize () const |
Returns the current pixel size of the texture. | |
const Size & | getOriginalDataSize () const |
Returns the original pixel size of the data loaded into the texture. | |
const Vector2 & | getTexelScaling () const |
Returns pixel to texel scale values that should be used for converting pixel values to texture co-ords. | |
void | loadFromFile (const String &filename, const String &resourceGroup) |
Loads the specified image file into the texture. The texture is resized as required to hold the image. | |
void | loadFromMemory (const void *buffer, const Size &buffer_size, PixelFormat pixel_format) |
Loads (copies) an image in memory into the texture. The texture is resized as required to hold the image. | |
void | saveToMemory (void *buffer) |
Save / dump the content of the texture to a memory buffer. The dumped pixel format is always RGBA (4 bytes per pixel). | |
Protected Member Functions | |

Texture implementation for the Direct3D10Renderer.
ID3D10ShaderResourceView* CEGUI::Direct3D10Texture::getDirect3DShaderResourceView | ( | ) | const |
Return the internal D3D10 shader resource view for the texture.
ID3D10Texture2D* CEGUI::Direct3D10Texture::getDirect3DTexture | ( | ) | const |
Return the internal D3D10 texture used by this Texture object.
const Size& CEGUI::Direct3D10Texture::getOriginalDataSize | ( | ) | const [virtual] |
Returns the original pixel size of the data loaded into the texture.
Implements CEGUI::Texture.
const Size& CEGUI::Direct3D10Texture::getSize | ( | ) | const [virtual] |
Returns the current pixel size of the texture.
Implements CEGUI::Texture.
const Vector2& CEGUI::Direct3D10Texture::getTexelScaling | ( | ) | const [virtual] |
Returns pixel to texel scale values that should be used for converting pixel values to texture co-ords.
Implements CEGUI::Texture.
void CEGUI::Direct3D10Texture::loadFromFile | ( | const String & | filename, |
const String & | resourceGroup | ||
) | [virtual] |
Loads the specified image file into the texture. The texture is resized as required to hold the image.
filename | The filename of the image file that is to be loaded into the texture |
resourceGroup | Resource group identifier to be passed to the resource provider when loading the image file. |
Implements CEGUI::Texture.
void CEGUI::Direct3D10Texture::loadFromMemory | ( | const void * | buffer, |
const Size & | buffer_size, | ||
PixelFormat | pixel_format | ||
) | [virtual] |
Loads (copies) an image in memory into the texture. The texture is resized as required to hold the image.
buffer | Pointer to the buffer containing the image data. |
buffer_size | Size of the buffer (in pixels as specified by pixelFormat) |
pixel_format | PixelFormat value describing the format contained in buffPtr. |
Implements CEGUI::Texture.
void CEGUI::Direct3D10Texture::saveToMemory | ( | void * | buffer | ) | [virtual] |
Save / dump the content of the texture to a memory buffer. The dumped pixel format is always RGBA (4 bytes per pixel).
