Returns an immutable proxy the to the pixel at index . | |
pixel_proxy | at (size_t index) |
Returns a mutable proxy the to the pixel at index . | |
const_pixel_proxy | operator[] (size_t index) const |
Returns an immutable proxy the to the pixel at index . The non-checking version. | |
pixel_proxy | operator[] (size_t index) |
