(1) The Numa is a struct holding an array of floats. It can also be used to store l_int32 values, with some loss of precision for floats larger than about 10 million. Use the L_Dna instead if integers larger than a few million need to be stored.
(2) Always use the accessors in this file, never the fields directly.
(3) Storing and retrieving numbers:
* to append a new number to the array, use numaAddNumber(). If the number is an int, it will will automatically be converted to l_float32 and stored.
* to reset a value stored in the array, use numaSetValue().
* to increment or decrement a value stored in the array, use numaShiftValue().
* to obtain a value from the array, use either numaGetIValue() or numaGetFValue(), depending on whether you are retrieving an integer or a float. This avoids doing an explicit cast, such as (a) return a l_float32 and cast it to an l_int32 (b) cast the return directly to (l_float32 *) to satisfy the function prototype, as in numaGetFValue(na, index, (l_float32 *)&ival); [ugly!]
(4) int <--> float conversions:
Tradition dictates that type conversions go automatically from l_int32 --> l_float32, even though it is possible to lose precision for large integers, whereas you must cast (l_int32) to go from l_float32 --> l_int32 because you're truncating to the integer value.
(5) As with other arrays in leptonica, the numa has both an allocated size and a count of the stored numbers. When you add a number, it goes on the end of the array, and causes a realloc if the array is already filled. However, in situations where you want to add numbers randomly into an array, such as when you build a histogram, you must set the count of stored numbers in advance. This is done with numaSetCount(). If you set a count larger than the allocated array, it does a realloc to the size requested.
(6) In situations where the data in a numa correspond to a function y(x), the values can be either at equal spacings in x or at arbitrary spacings. For the former, we can represent all x values by two parameters: startx (corresponding to y[0]) and delx for the change in x for adjacent values y[i] and y[i+1]. startx and delx are initialized to 0.0 and 1.0, rsp. For arbitrary spacings, we use a second numa, and the two numas are typically denoted nay and nax.
(7) The numa is also the basic struct used for histograms. Every numa has startx and delx fields, initialized to 0.0 and 1.0, that can be used to represent the "x" value for the location of the first bin and the bin width, respectively. Accessors are the numa*Parameters() functions. All functions that make numa histograms must set these fields properly, and many functions that use numa histograms rely on the correctness of these values.

Notes: (1) This function is convenient for doing direct manipulation on a fixed size array of Numas. To do this, it sets the count to the full size of the allocated array of Numa ptrs. The originating Numaa owns this array: DO NOT free it! (2) Intended usage: Numaa *naa = numaaCreate(n); Numa **array = numaaGetPtrArray(naa); ... [manipulate Numas directly on the array] numaaDestroy(&naa); (3) Cautions: ~ Do not free this array; it is owned by tne Numaa. ~ Do not call any functions on the Numaa, other than numaaDestroy() when you're finished with the array. Adding a Numa will force a resize, destroying the ptr array. ~ Do not address the array outside its allocated size. With the bare array, there are no protections. If the allocated size is n, array[n] is an error.

[in] | na | |
[in] | copyflag | L_NOCOPY or L_COPY |
Notes: (1) If copyflag == L_COPY, it makes a copy which the caller is responsible for freeing. Otherwise, it operates directly on the bare array of the numa. (2) Very important: for L_NOCOPY, any writes to the array will be in the numa. Do not write beyond the size of the count field, because it will not be accessible from the numa! If necessary, be sure to set the count field to a larger number (such as the alloc size) BEFORE calling this function. Creating with numaMakeConstant() is another way to insure full initialization.

l_int32* numaGetIArray | ( | NUMA * | na | ) |
[in] | na |
Notes: (1) A copy of the array is always made, because we need to generate an integer array from the bare float array. The caller is responsible for freeing the array. (2) The array size is determined by the number of stored numbers, not by the size of the allocated array in the Numa. (3) This function is provided to simplify calculations using the bare internal array, rather than continually calling accessors on the numa. It is typically used on an array of size 256.
