Public Member Functions | |
const String & | getName () const |
Returns the name given to the texture when it was created. | |
const Sizef & | getSize () const |
Returns the current pixel size of the texture. | |
const Sizef & | getOriginalDataSize () const |
Returns the original pixel size of the data loaded into the texture. | |
const Vector2f & | 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 Sizef &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 | blitFromMemory (const void *sourceData, const Rectf &area) |
Performs an area memory blit to the texture. | |
void | blitToMemory (void *targetData) |
Performs a complete blit from the texture surface to memory. | |
bool | isPixelFormatSupported (const PixelFormat fmt) const |
Return whether the specified pixel format is supported by the system for the CEGUI::Texture implementation. | |

Implements CEGUI::Texture.
bool CEGUI::NullTexture::isPixelFormatSupported | ( | const PixelFormat | fmt | ) | const [virtual] |
Return whether the specified pixel format is supported by the system for the CEGUI::Texture implementation.
The result of this call will vary according to the implementaion API and the capabilities of the hardware.
fmt | One of the PixelFormat enumerated values specifying the pixel format that is to be tested. |
