Vips.Object.local_array (original) (raw)

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; `

This method is not directly available to language bindings.

Parameters

Return value

Type: VipsObject

An array of NULL pointers of length n.

The returned data is owned by the instance.
