### Method

# Rsvg Handleget_geometry_for_element

#### Declaration [src]

    gboolean
    rsvg_handle_get_geometry_for_element (
      RsvgHandle* handle,
      const char* id,
      RsvgRectangle* out_ink_rect,
      RsvgRectangle* out_logical_rect,
      GError** error
    )

#### Description [src]

Computes the ink rectangle and logical rectangle of a single SVG element.

While `rsvg_handle_get_geometry_for_layer` computes the geometry of an SVG element subtree with its transformation matrix, this other function will compute the element’s geometry as if it were being rendered under an identity transformation by itself. That is, the resulting geometry is as if the element got extracted by itself from the SVG.

This function is the counterpart to `rsvg_handle_render_element`.

Element IDs should look like an URL fragment identifier; for example, pass `#foo` (hash `foo`) to get the geometry of the element that has an `id="foo"` attribute.

The “ink rectangle” is the bounding box that would be painted for fully- stroked and filled elements.

The “logical rectangle” just takes into account the unstroked paths and text outlines.

Note that these bounds are not minimum bounds; for example, clipping paths are not taken into account.

You can pass `NULL` for the `id` if you want to measure all the elements in the SVG, i.e. to measure everything from the root element.

This operation is not constant-time, as it involves going through all the child elements.

Available since: | 2.46

#### Parameters

`id` | `const char*`
| An element’s id within the SVG, starting with “#” (a single hash character), for example, `#layer1`. This notation corresponds to a URL’s fragment ID. Alternatively, pass `NULL` to compute the geometry for the whole SVG.
| The argument can be `NULL`.
| The data is owned by the caller of the function.
| The value is a NUL terminated UTF-8 string.
`out_ink_rect` | `RsvgRectangle`
| Place to store the ink rectangle of the element.
| The argument will be set by the function.
| The argument can be `NULL`.
| The data is owned by the caller of the function.
`out_logical_rect` | `RsvgRectangle`
| Place to store the logical rectangle of the element.
| The argument will be set by the function.
| The argument can be `NULL`.
| The data is owned by the caller of the function.
`error` | `GError **`
| The return location for a `GError*`, or `NULL`.

#### Return value

Returns: | `gboolean`
| `TRUE` if the geometry could be obtained, or `FALSE` on error. Errors are returned in the `error` argument. API ordering: This function must be called on a fully-loaded `handle`. See the section “API ordering” for details. Panics: this function will panic if the `handle` is not fully-loaded.
