33 * <pre>
34 * This file has typedefs for the following array structs:
35 * struct Numa array of floats
36 * struct Numaa
37 * struct L_Dna array of doubles
38 * struct L_Dnaa
39 * struct L_Dnahash
40 * struct Sarray array of C-strings
41 * struct L_Bytea array of bytes
42 *
43 * It contains definitions for:
44 * Numa interpolation flags
45 * Numa border flags
46 * Numa data type conversion to string
47 *
48 * Here are the non-image-related arrays in leptonica:
49 * * Numa, L_Dna, L_Ptra, Sarray:
50 * These have most of the typical operations of vectors, such as add,
51 * insert, remove and replace.
52 * * Numaa, L_Dnaa, L_Ptraa:
53 * These are arrays of float, double and generic pointer arrays.
54 * * L_Bytea:
55 * This is an array of bytes, analogous to a C++ string.
56 * * L_Dnahash:
57 * This is a simple hashing for integers, used in the jbig2 classifier.
58 * </pre>
