DESCRIPTION

17       im_version(3)  returns the major version number if flag == 0, the minor
18       version number if flag == 1, and the micro version number if flag == 2.
19
20       Major versions are supposed to represent  very  large  changes  to  the
21       library,  minor  versions  indicate steady improvements (with odd minor
22       versions indicating unstable and  undocumented  development  releases),
23       and micro versions indicating bug-fixes.
24
25       im_version_string(3) returns a static string representing the vips ver‐
26       sion number, and the date when the library was built.
27
28       The version number always has three parts, separated by '.' characters.
29       The  first part is the major release, the second the minor release (odd
30       minor values denote development releases), and the third the micro ver‐
31       sion number.
32
33       The version number and the date are separated by a '-' character.
34
35       The value of this string is constructed in 'configure.in'.
36
37       A typical value for tthe string might be "7.7.0-Thu Dec 16 18:10:01 GMT
38       1999".
