For instance, p_array, p_runs. + +IDEA: unique<S> is a site-set morpher that first tests that the +reference set does not have any element with multiplicity and then +statically change the multiplicity property to "unique". For +instance, an object of type unique< p_array > is ensured to have no +element with multiplicity---as a consequence, such an object neither +features an imperative "op[i]" nor an "append(p)" method. + +Having site-sets with multiplicity can result in weird definitions of +images. Imagine a contour like an '8' encoded from a p_array; for +the same site, but two different psites, we can have two different +values: + + a + h b + c/g <- same point, say p, but both psites c and g + d f + e + +In that particular example, ima(c) can be different from ima(g); of +course, we cannot write ima(p) since its data are not point-wise +accessible. + +*** boxes + +Boxes are defined on grids. A n-d box is a pair (p_min, p_max). A +n-d point is (coord_0, .., coord_(n-1)). A DEFAULT ordering +relationship is defined to be used with containers of points; it +relies on the lexicographic ordering of the coordinates. This default +ordering is also the box2d.is_forward_before(p1, p2). + + +*** run-based point-sets + +**** run + +A run is a couple (p_start, len); it contains the set of points browse +by: for i from 0 to len-1, p = p_start + i * d, where d = (0,..,0, 1). +Remark: the last coordinate of points and dpoints, whatever the +dimension is, is the one that changes the most often when browsing a +box. + +A run_psite is the couple (p_start, i). + +**** runs + +A "runs" is a set of runs which are sorted with the default ordering +of points. For instance, this "runs" point-set: +.b**..... +c*...a*** +is: {(b,3), (c,2), (a,4)}. + +A runs_psite is a (i_of_run, i_in_run, ptr towards the "runs"). To +access the data of an image encoded by runs, the ptr can be null; in +that case, we cannot test if this psite matches the image domain. + +Please note that a runs_psite p can NOT be (p_start, i) because, in +that case, the .has(p) method has the O(N) complexity since browsing +the array of runs is required. + + + +* tour + + +** primary images + +name short description ima(p) + +--------------------------------------------------------------------------------------------------------- + +image2d<T> rectangle image on 2d integer grid; = .data[p.row][p.col] + data in RAM; outer border + +mmap_image2d<T> likewise but data are "memory mapped" + +file_image2d<T> likewise but data are stored in a file + and border is fixed + +tiled_image FIXME: ... + say that piter (for_all tile, for_all p of tile) is different from fwd_piter + +fun_image<S,F> defined by a domain and a function : p -> v -> .f(p) + +flat_image<S,T> defined by a domain with the same value for all p = .val + +pkey_image<P,T> defined by couples (p,v) where p is a key r: assert(.data.has_key(p)); -> .data[p] + to retrieve v w: .data[p] <- v + +pvkeys_image<P,T> defined by couples (p,v), p being the key, and at + the same time, coherently maintaining couples + (v,[p]) where v is the key. + +--------------------------------------------------------------------------------------------------------- + graph-based images + + FIXME: Cf.
