Detailed Description
template<class T>
class CVD::BasicImage< T >
A generic image class to manage a block of data as an image.
Provides basic image access such as accessing a particular pixel co-ordinate.
- Parameters:
-
T The pixel type for this image. Typically either CVD::byteorCVD::Rgb<CVD::byte> >are used, but images could be constructed of any available type.
A BasicImage does not manage its own data, but provides access to an arbitrary externally-managed block of data as though it were an image. Use the derived Image class if you want an image which also has its own data.
Loading and saving, format conversion and some copying functionality is provided by external functions rather than as part of this class. See the Image loading and saving, and format conversion module for documentation of these functions.
Member Typedef Documentation
| typedef T* CVD::BasicImage< T >::iterator |
A random-access iterator to read or write pixel values from the image.
This can be incremented, decremented and dereferenced. Incrementing this iterator steps through pixels in the usual scanline order.
Reimplemented from CVD::SubImage< T >.
| typedef const T* CVD::BasicImage< T >::const_iterator |
A random-access iterator to read pixel values from the image.
This can be incremented, decremented and dereferenced. Incrementing this iterator steps through pixels in the usual scanline order.
Reimplemented from CVD::SubImage< T >.

Member Function Documentation
| const_iterator CVD::BasicImage< T >::begin | ( | ) | const [inline] |
Returns a const iterator referencing the first (top-left) pixel in the image.
Reimplemented from CVD::SubImage< T >.

Referenced by CVD::Image< GRADIENT >::copy_from(), CVD::dense_tensor_vote_gradients(), and CVD::threshold().
| iterator CVD::BasicImage< T >::begin | ( | ) | [inline] |
Returns an iterator referencing the first (top-left) pixel in the image.
Reimplemented from CVD::SubImage< T >.
| const_iterator CVD::BasicImage< T >::end | ( | ) | const [inline] |
Returns a const iterator referencing the pixel immediately after the last (bottom-right) pixel in the image.
