NAME

SYNOPSIS

9       #include <vips/vips.h>
10
11       void im_histlin( variable_list )

DESCRIPTION

14       im_histlin(3)  appends  one  line  of history consisting of a buffer of
15       data, time, history and CR in history section of the image descriptor.
16
17       The format of ( variable_list ) is:
18
19        (image_descriptor, format, arg1, arg2, ...)
20
21       where format, arg1, arg2, ... are the same as in  printf.  If  Hist  is
22       NULL,  then im_histlin(3) makes up a one-line history, of just the file
23       name.
24
25       The user should set up format, arg1, arg2, ... in such a way  that  the
26       added  history  line  corresponds to the command line which creates the
27       same effect with the same arguments.  It can be used after  calling  an
28       im_function.   It  is  simpler  to  use  the  function im_updatehist(3)
29       instead.
30

RETURN VALUE

32       The function returns 0 on success and -1 on error.
