| Texture2D () | |
| The constructors. | |
| Texture2D (int arows, int acols, Format aformat, unsigned int atexId, bool autoRelease=false) | |
| Texture2D (Size asize, Format aformat, unsigned int atexId, bool autoRelease=false) | |
| Texture2D (int arows, int acols, Format aformat, bool autoRelease=false) | |
| This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts. | |
| Texture2D (Size asize, Format aformat, bool autoRelease=false) | |
| This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts. | |
| Texture2D (InputArray arr, bool autoRelease=false) | |
| This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts. | |
| void | create (int arows, int acols, Format aformat, bool autoRelease=false) |
| Allocates memory for ogl::Texture2D object. | |
| void | create (Size asize, Format aformat, bool autoRelease=false) |
| This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts. | |
| void | release () |
| Decrements the reference counter and destroys the texture object if needed. | |
| void | setAutoRelease (bool flag) |
| Sets auto release mode. | |
| void | copyFrom (InputArray arr, bool autoRelease=false) |
| Copies from host/device memory to OpenGL texture. | |
| void | copyTo (OutputArray arr, int ddepth=CV_32F, bool autoRelease=false) const |
| Copies from OpenGL texture to host/device memory or another OpenGL texture object. | |
| void | bind () const |
| Binds texture to current active texture unit for GL_TEXTURE_2D target. | |
| unsigned int | texId () const |
| get OpenGL opject id | |
