Method

VipsObjectlocal_array

Declaration [src] 

VipsObject**
vips_object_local_array (
  VipsObject* parent,
  int n
)

Description [src]

Make an array of NULL VipsObject pointers. When parent closes, every non-NULL pointer in the array will be unreffed and the array will be freed. Handy for creating a set of temporary images for a function.

The array is NULL-terminated, ie. contains an extra NULL element at the end.

Example:

VipsObject **t;

t = vips_object_local_array( parent, 5 );
if(
  vips_add( a, b, &t[0], NULL ) ||
  vips_invert( t[0], &t[1], NULL ) ||
  vips_add( t[1], t[0], &t[2], NULL ) ||
  vips_costra( t[2], out, NULL ) )
  return( -1 );
