handle can be used to load an image.

The preferred way of loading SVG data into the returned #RsvgHandle is with
rsvg_handle_read_stream_sync().

The deprecated way of loading SVG data is with rsvg_handle_write() and
rsvg_handle_close(); note that these require buffering the entire file
internally, and for this reason it is better to use the stream functions:
rsvg_handle_new_from_stream_sync(), rsvg_handle_read_stream_sync(), or
rsvg_handle_new_from_gfile_sync().

After loading the #RsvgHandle with data, you can render it using Cairo or get
a GdkPixbuf from it. When finished, free the handle with g_object_unref(). No
more than one image can be loaded with one handle.

Note that this function creates an #RsvgHandle with no flags set.  If you
require any of #RsvgHandleFlags to be set, use any of
rsvg_handle_new_with_flags(), rsvg_handle_new_from_stream_sync(), or
rsvg_handle_new_from_gfile_sync().</doc>

rsvg_handle_read_stream_sync(), then you do not need to call this function.

This will return %TRUE if the loader closed successfully and the
SVG data was parsed correctly.  Note that @handle isn't freed until
@g_object_unref is called.</doc>

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 &lt;literal&gt;foo&lt;/literal&gt;) to get the geometry of the element that
has an &lt;literal&gt;id="foo"&lt;/literal&gt; 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.

If you are calling this function to compute a scaling factor to render the SVG,
consider simply using rsvg_handle_render_document() instead; it will do the
scaling computations automatically.

As an example, the following SVG element has a &lt;literal&gt;width&lt;/literal&gt; of 100 pixels and a &lt;literal&gt;height&lt;/literal&gt; of 400 pixels, but no &lt;literal&gt;viewBox&lt;/literal&gt;:

|[
&lt;svg xmlns="http://www.w3.org/2000/svg" width="100" height="400"&gt;
]|

Conversely, the following element has a &lt;literal&gt;viewBox&lt;/literal&gt;, but no &lt;literal&gt;width&lt;/literal&gt; or &lt;literal&gt;height&lt;/literal&gt;:

|[
&lt;svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 100 400"&gt;
]|

Note that the #RsvgLength return values have #RsvgUnits in them; you should
not assume that they are always in pixels.  For example, the following SVG element
will return a width value whose &lt;literal&gt;units&lt;/literal&gt; field is RSVG_UNIT_MM.

This function is able to extract the size in pixels from an SVG document if the
document has both &lt;literal&gt;width&lt;/literal&gt; and &lt;literal&gt;height&lt;/literal&gt; attributes
with physical units (px, in, cm, mm, pt, pc) or font-based units (em, ex).  For
physical units, the dimensions are normalized to pixels using the dots-per-inch (DPI)
value set previously with rsvg_handle_set_dpi().  For font-based units, this function
uses the computed value of the `font-size` property for the toplevel
&lt;literal&gt;&amp;lt;svg&amp;gt;&lt;/literal&gt; element.  In those cases, this function returns %TRUE.

This function is not able to extract the size in pixels directly from the intrinsic
dimensions of the SVG document if the &lt;literal&gt;width&lt;/literal&gt; or
&lt;literal&gt;height&lt;/literal&gt; are in percentage units (or if they do not exist, in which
case the SVG spec mandates that they default to 100%), as these require a
&lt;firstterm&gt;viewport&lt;/firstterm&gt; to be resolved to a final size.  In this case, the
function returns %FALSE.

For example, the following document fragment has intrinsic dimensions that will resolve
to 20x30 pixels.

|[
&lt;svg xmlns="http://www.w3.org/2000/svg" width="20" height="30"/&gt;
]|

Similarly, if the DPI is set to 96, this document will resolve to 192x288 pixels (i.e. 96*2 x 96*3).

|[
&lt;svg xmlns="http://www.w3.org/2000/svg" width="2in" height="3in"/&gt;
]|

The dimensions of the following documents cannot be resolved to pixels directly, and
this function would return %FALSE for them:

|[
&lt;!-- Needs a viewport against which to compute the percentages. --&gt;
&lt;svg xmlns="http://www.w3.org/2000/svg" width="100%" height="100%"/&gt;

&lt;!-- Does not have intrinsic width/height, just a 1:2 aspect ratio which
     needs to be fitted within a viewport. --&gt;
&lt;svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 100 200"/&gt;
]|

Instead of querying an SVG document's size, applications are encouraged to render SVG
documents to a size chosen by the application, by passing a suitably-sized viewport to
rsvg_handle_render_document().</doc>

    ex), the function computes the size directly based on the dots-per-inch (DPI) you
    have configured with rsvg_handle_set_dpi().  This is the same approach as
    rsvg_handle_get_intrinsic_size_in_pixels().
  &lt;/listitem&gt;

    &lt;literal&gt;100%&lt;/literal&gt; (or if they don't exist at all and thus default to 100%),
    the function uses the width and height of the viewBox as a pixel size.  This
    produces a rendered document with the correct aspect ratio.
  &lt;/listitem&gt;
  &lt;listitem&gt;
     Otherwise, this function computes the extents of every graphical object in the SVG
     document to find the total extents.  This is moderately expensive, but no more expensive
     than rendering the whole document, for example.

  &lt;listitem&gt;
    This function cannot deal with percentage-based units for &lt;literal&gt;width&lt;/literal&gt;
    and &lt;literal&gt;height&lt;/literal&gt; because there is no viewport against which they could
    be resolved; that is why it will compute the extents of objects in that case.  This
    is why we recommend that you use rsvg_handle_render_document() instead, which takes
    in a viewport and follows the sizing policy from the web platform.
  &lt;/listitem&gt;
&lt;/itemizedlist&gt;

Drawing will occur with respect to the @cr's current transformation: for example, if
the @cr has a rotated current transformation matrix, the whole SVG will be rotated in
the rendered version.

This function depends on the #RsvgHandle's DPI to compute dimensions in
pixels, so you should call rsvg_handle_set_dpi() beforehand.

Note that @cr must be a Cairo context that is not in an error state, that is,
cairo_status() must return #CAIRO_STATUS_SUCCESS for it.  Cairo can set a
context to be in an error state in various situations, for example, if it was
passed an invalid matrix or if it was created for an invalid surface.</doc>

reusable objects in an SVG and want to render them individually; for example, an
SVG full of icons that are meant to be be rendered independently of each other.

You can pass #NULL for the @id if you want to render all
the elements in the SVG, i.e. to render everything from the

be rendered.  FIXME: mention proportional scaling.

           line="81">This is the main entry point into the librsvg library.  An RsvgHandle is an
object that represents SVG data in memory.  Your program creates an
RsvgHandle from an SVG file, or from a memory buffer that contains SVG data,
or in the most general form, from a #GInputStream that will provide SVG data.

Librsvg can load SVG images and render them to Cairo surfaces,
using a mixture of SVG's [static mode] and [secure static mode].
Librsvg does not do animation nor scripting, and can load
references to external data only in some situations; see below.

Librsvg supports reading &lt;ulink
url="https://www.w3.org/TR/SVG11/"&gt;SVG 1.1&lt;/ulink&gt; data, and is
gradually adding support for features in &lt;ulink
url="https://www.w3.org/TR/SVG2/"&gt;SVG 2&lt;/ulink&gt;.  Librsvg also supports
SVGZ files, which are just an SVG stream compressed with the GZIP algorithm.

# The "base file" and resolving references to external files

When you load an SVG, librsvg needs to know the location of the "base file"
for it.  This is so that librsvg can determine the location of referenced
entities.  For example, say you have an SVG in &lt;filename&gt;/foo/bar/foo.svg&lt;/filename&gt;
and that it has an image element like this:

|[
&lt;image href="resources/foo.png" .../&gt;
]|

In this case, librsvg needs to know the location of the toplevel
&lt;filename&gt;/foo/bar/foo.svg&lt;/filename&gt; so that it can generate the appropriate
reference to &lt;filename&gt;/foo/bar/resources/foo.png&lt;/filename&gt;.

## Security and locations of referenced files

When processing an SVG, librsvg will only load referenced files if they are
in the same directory as the base file, or in a subdirectory of it.  That is,
if the base file is &lt;filename&gt;/foo/bar/baz.svg&lt;/filename&gt;, then librsvg will
only try to load referenced files (from SVG's
&lt;literal&gt;&amp;lt;image&amp;gt;&lt;/literal&gt; element, for example, or from content
included through XML entities) if those files are in &lt;filename&gt;/foo/bar/&lt;!--
--&gt;*&lt;/filename&gt; or in &lt;filename&gt;/foo/bar/&lt;!-- --&gt;*&lt;!-- --&gt;/.../&lt;!--
--&gt;*&lt;/filename&gt;.  This is so that malicious SVG files cannot include files
that are in a directory above.

The full set of rules for deciding which URLs may be loaded is as follows;
they are applied in order.  A referenced URL will not be loaded as soon as
one of these rules fails:

&lt;orderedlist&gt;
  &lt;listitem&gt;
    All &lt;literal&gt;data:&lt;/literal&gt; URLs may be loaded.  These are sometimes used
    to include raster image data, encoded as base-64, directly in an SVG file.
  &lt;/listitem&gt;

  &lt;listitem&gt;
    URLs with queries ("?") or fragment identifiers ("#") are not allowed.
  &lt;/listitem&gt;

  &lt;listitem&gt;
    All other URL schemes other than data: in references require a base URL.  For
    example, this means that if you load an SVG with
    rsvg_handle_new_from_data() without calling rsvg_handle_set_base_uri(),
    then any referenced files will not be allowed (e.g. raster images to be
    loaded from other files will not work).
  &lt;/listitem&gt;

  &lt;listitem&gt;
    If referenced URLs are absolute, rather than relative, then they must
    have the same scheme as the base URL.  For example, if the base URL has a
    "&lt;literal&gt;file&lt;/literal&gt;" scheme, then all URL references inside the SVG must
    also have the "&lt;literal&gt;file&lt;/literal&gt;" scheme, or be relative references which
    will be resolved against the base URL.
  &lt;/listitem&gt;

  &lt;listitem&gt;
    If referenced URLs have a "&lt;literal&gt;resource&lt;/literal&gt;" scheme, that is,
    if they are included into your binary program with GLib's resource
    mechanism, they are allowed to be loaded (provided that the base URL is
    also a "&lt;literal&gt;resource&lt;/literal&gt;", per the previous rule).
  &lt;/listitem&gt;

  &lt;listitem&gt;
    Otherwise, non-&lt;literal&gt;file&lt;/literal&gt; schemes are not allowed.  For
    example, librsvg will not load &lt;literal&gt;http&lt;/literal&gt; resources, to keep
    malicious SVG data from "phoning home".
  &lt;/listitem&gt;

  &lt;listitem&gt;
    A relative URL must resolve to the same directory as the base URL, or to
    one of its subdirectories.  Librsvg will canonicalize filenames, by
    removing ".." path components and resolving symbolic links, to decide whether
    files meet these conditions.
  &lt;/listitem&gt;
&lt;/orderedlist&gt;

# Loading an SVG with GIO

This is the easiest and most resource-efficient way of loading SVG data into
an #RsvgHandle.

If you have a #GFile that stands for an SVG file, you can simply call
rsvg_handle_new_from_gfile_sync() to load an RsvgHandle from it.

Alternatively, if you have a #GInputStream, you can use
rsvg_handle_new_from_stream_sync().

Both of those methods allow specifying a #GCancellable, so the loading
process can be cancelled from another thread.

## Loading an SVG from memory

If you already have SVG data in a byte buffer in memory, you can create a
memory input stream with g_memory_input_stream_new_from_data() and feed that
to rsvg_handle_new_from_stream_sync().

Note that in this case, it is important that you specify the base_file for
the in-memory SVG data.  Librsvg uses the base_file to resolve links to
external content, like raster images.

# Loading an SVG without GIO

You can load an RsvgHandle from a simple filename or URI with
rsvg_handle_new_from_file().  Note that this is a blocking operation; there
is no way to cancel it if loading a remote URI takes a long time.  Also, note that
this method does not let you specify #RsvgHandleFlags.

Otherwise, loading an SVG without GIO is not recommended, since librsvg will
need to buffer your entire data internally before actually being able to
parse it.  The deprecated way of doing this is by creating a handle with
rsvg_handle_new() or rsvg_handle_new_with_flags(), and then using
rsvg_handle_write() and rsvg_handle_close() to feed the handle with SVG data.
Still, please try to use the GIO stream functions instead.

# Resolution of the rendered image (dots per inch, or DPI)

SVG images can contain dimensions like "&lt;literal&gt;5 cm&lt;/literal&gt;" or
"&lt;literal&gt;2 pt&lt;/literal&gt;" that must be converted from physical units into
device units.  To do this, librsvg needs to know the actual dots per inch
(DPI) of your target device.  You can call rsvg_handle_set_dpi() or
rsvg_handle_set_dpi_x_y() on an RsvgHandle to set the DPI before rendering
it.

# Rendering

The preferred way to render a whole SVG document is to use
rsvg_handle_render_document().  Please see its documentation for
details.

# API ordering

Due to the way the librsvg API evolved over time, an #RsvgHandle object is available
for use as soon as it is constructed.  However, not all of its methods can be
called at any time.  For example, an #RsvgHandle just constructed with rsvg_handle_new()
is not loaded yet, and it does not make sense to call rsvg_handle_render_document() on it
just at that point.

The documentation for the available methods in #RsvgHandle may mention that a particular
method is only callable on a "fully loaded handle".  This means either:

&lt;itemizedlist&gt;
  &lt;listitem&gt;
    The handle was loaded with rsvg_handle_write() and rsvg_handle_close(), and
    those functions returned no errors.
  &lt;/listitem&gt;
  &lt;listitem&gt;
    The handle was loaded with rsvg_handle_read_stream_sync() and that function
    returned no errors.
  &lt;/listitem&gt;
&lt;/itemizedlist&gt;

Before librsvg 2.46, the library did not fully verify that a handle was in a
fully loaded state for the methods that require it.  To preserve
compatibility with old code which inadvertently called the API without
checking for errors, or which called some methods outside of the expected
order, librsvg will just emit a g_critical() message in those cases.

New methods introduced in librsvg 2.46 and later will check for the correct
ordering, and panic if they are called out of order.  This will abort
the program as if it had a failed assertion.</doc>
