SYNOPSIS

10       #include <vips/vips.h>

12       void im_debugim( image )

DESCRIPTION

19       im_debugim(3) prints to the standard error output raw data  pointed  by
20       image sequentially.  Data are printed as float numbers and the function
21       interprets the input format properly.  If input  is  complex  then  for
22       each  pixel the real part followed by the imaginary is printed.  It can
23       be used for debugging preferably on small images.  If  input  is  uchar
24       then the printed values are integers.
25
26       im_printlines  printes in the standard error output the no of line fol‐
27       lowed by CR, followed by the line pixel values.  For each pixel, the  x
28       location  followed  by the pixel value(s) is printed.  The location and
29       the pixels value(s) are separated by a tab.  Each pixel is printed on a
30       separate line.
