Function

VipsAreanew

Declaration [src] 

VipsArea*
vips_area_new (
  VipsCallbackFn free_fn,
  void* data
)

Description [src]

A VipsArea wraps a chunk of memory. It adds reference counting and a free function. It also keeps a count and a GType, so the area can be an array.

This type is used for things like passing an array of double or an array of VipsObject pointers to operations, and for reference-counted immutable strings.

Initial count == 1, so vips_area_unref() after attaching somewhere.

The caller of the function takes ownership of the data, and is responsible for freeing it.
