Vips.Image.copy_memory

### Method

# Vips Imagecopy_memory

#### Declaration [src]

    VipsImage*
    vips_image_copy_memory (
      VipsImage* image
    )

#### Description [src]

This function allocates memory, renders `image` into it, builds a new image around the memory area, and returns that.

If the image is already a simple area of memory, it just refs `image` and returns it.

Call this before using the draw operations to make sure you have a memory image that can be modified.

`vips_copy()` adds a null “copy” node to a pipeline. Use that instead if you want to change metadata and not pixels.

This operation is thread-safe, unlike `vips_image_wio_input()`.

If you are sure that `image` is not shared with another thread (perhaps you have made it yourself), use `vips_image_wio_input()` instead.

See also

`vips_image_wio_input()`.

#### Return value

Type: `VipsImage`

The new `VipsImage`, or `NULL` on error.

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