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.

::: seealso vips_area_unref().

Parameters

`free_fn`	`VipsCallbackFn`
	`data` will be freed with this function.
`data`	`void*`
	Data will be freed with this function.
	The argument can be `NULL`.
	The called function takes ownership of the data, and is responsible for freeing it.

Return value

Returns:	`VipsArea`
	The new `VipsArea`.
	The caller of the function takes ownership of the data, and is responsible for freeing it.
