virtual ushort | getWidth (void) const |
Returns the current pixel width of the texture. | |
virtual ushort | getHeight (void) const |
Returns the current pixel height of the texture. | |
virtual ushort | getOriginalWidth (void) const |
Returns the original pixel width of the data loaded into the texture. | |
virtual ushort | getOriginalHeight (void) const |
Returns the original pixel height of the data loaded into the texture. | |
virtual float | getXScale (void) const |
Returns the current scale used for the width of the texture. | |
virtual float | getYScale (void) const |
Returns the current scale used for the height of the texture. | |
virtual 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. | |
virtual void | loadFromMemory (const void *buffPtr, uint buffWidth, uint buffHeight, PixelFormat pixelFormat) |
Loads (copies) an image in memory into the texture. The texture is resized as required to hold the image. | |
GLuint | getOGLTexid (void) const |
Return a pointer to the internal texture id. | |
void | setOGLTextureSize (uint size) |
set the size of the internal texture. | |
void | grabTexture (void) |
Grab the texture to a local buffer. This will destroy the OpenGL texture, and restoreTexture must be called before using it again. | |
void | restoreTexture (void) |
Restore the texture from the locally buffered copy previously create by a call to grabTexture. | |
