template<class T>
class ufo::Image< T >
Image class for storing and manipulating 2D pixel data.
- Template Parameters
-
Image owns its pixel data and provides both flat (single-index) and two-dimensional (row, col) element access. The storage layout is contiguous and row-major, meaning that pixels in the same row are adjacent in memory.
The class satisfies std::ranges::contiguous_range, so it can be used directly with range algorithms and range-based for loops.
