The `GDK_INTERP_NEAREST` mode is the fastest scaling method, but has
horrible quality when scaling down; `GDK_INTERP_BILINEAR` is the best
choice if you aren&#039;t sure what to choose, it has a good speed/quality
balance.

**Note**: Cubic filtering is missing from the list; hyperbolic
interpolation is just as fast and results in higher quality.&lt;/doc&gt;

 it has a lower quality than the @GDK_INTERP_BILINEAR filter

           line=&quot;24&quot;&gt;A pixel buffer.

`GdkPixbuf` contains information about an image&#039;s pixel data,
its color space, bits per sample, width and height, and the
rowstride (the number of bytes between the start of one row
and the start of the next).

## Creating new `GdkPixbuf`

The most basic way to create a pixbuf is to wrap an existing pixel
buffer with a [class@GdkPixbuf.Pixbuf] instance. You can use the
[`ctor@GdkPixbuf.Pixbuf.new_from_data`] function to do this.

Every time you create a new `GdkPixbuf` instance for some data, you
will need to specify the destroy notification function that will be
called when the data buffer needs to be freed; this will happen when
a `GdkPixbuf` is finalized by the reference counting functions. If
you have a chunk of static data compiled into your application, you
can pass in `NULL` as the destroy notification function so that the
data will not be freed.

The [`ctor@GdkPixbuf.Pixbuf.new`] constructor function can be used
as a convenience to create a pixbuf with an empty buffer; this is
equivalent to allocating a data buffer using `malloc()` and then
wrapping it with `gdk_pixbuf_new_from_data()`. The `gdk_pixbuf_new()`
function will compute an optimal rowstride so that rendering can be
performed with an efficient algorithm.

As a special case, you can use the [`ctor@GdkPixbuf.Pixbuf.new_from_xpm_data`]
function to create a pixbuf from inline XPM image data.

You can also copy an existing pixbuf with the [method@Pixbuf.copy]
function. This is not the same as just acquiring a reference to
the old pixbuf instance: the copy function will actually duplicate
the pixel data in memory and create a new [class@Pixbuf] instance
for it.

## Reference counting

`GdkPixbuf` structures are reference counted. This means that an
application can share a single pixbuf among many parts of the
code. When a piece of the program needs to use a pixbuf, it should
acquire a reference to it by calling `g_object_ref()`; when it no
longer needs the pixbuf, it should release the reference it acquired
by calling `g_object_unref()`. The resources associated with a
`GdkPixbuf` will be freed when its reference count drops to zero.
Newly-created `GdkPixbuf` instances start with a reference count
of one.

## Image Data

Image data in a pixbuf is stored in memory in an uncompressed,
packed format. Rows in the image are stored top to bottom, and
in each row pixels are stored from left to right.

There may be padding at the end of a row.

The &quot;rowstride&quot; value of a pixbuf, as returned by [`method@GdkPixbuf.Pixbuf.get_rowstride`],
indicates the number of bytes between rows.

**NOTE**: If you are copying raw pixbuf data with `memcpy()` note that the
last row in the pixbuf may not be as wide as the full rowstride, but rather
just as wide as the pixel data needs to be; that is: it is unsafe to do
`memcpy (dest, pixels, rowstride * height)` to copy a whole pixbuf. Use
[method@GdkPixbuf.Pixbuf.copy] instead, or compute the width in bytes of the
last row as:

```c
last_row = width * ((n_channels * bits_per_sample + 7) / 8);
```

The same rule applies when iterating over each row of a `GdkPixbuf` pixels
array.

The following code illustrates a simple `put_pixel()`
function for RGB pixbufs with 8 bits per channel with an alpha
channel.

```c
static void
put_pixel (GdkPixbuf *pixbuf,
           int x,
	   int y,
	   guchar red,
	   guchar green,
	   guchar blue,
	   guchar alpha)
{
  int n_channels = gdk_pixbuf_get_n_channels (pixbuf);

  // Ensure that the pixbuf is valid
  g_assert (gdk_pixbuf_get_colorspace (pixbuf) == GDK_COLORSPACE_RGB);
  g_assert (gdk_pixbuf_get_bits_per_sample (pixbuf) == 8);
  g_assert (gdk_pixbuf_get_has_alpha (pixbuf));
  g_assert (n_channels == 4);

  int width = gdk_pixbuf_get_width (pixbuf);
  int height = gdk_pixbuf_get_height (pixbuf);

  // Ensure that the coordinates are in a valid range
  g_assert (x &amp;gt;= 0 &amp;amp;&amp;amp; x &amp;lt; width);
  g_assert (y &amp;gt;= 0 &amp;amp;&amp;amp; y &amp;lt; height);

  int rowstride = gdk_pixbuf_get_rowstride (pixbuf);

  // The pixel buffer in the GdkPixbuf instance
  guchar *pixels = gdk_pixbuf_get_pixels (pixbuf);

  // The pixel we wish to modify
  guchar *p = pixels + y * rowstride + x * n_channels;
  p[0] = red;
  p[1] = green;
  p[2] = blue;
  p[3] = alpha;
}
```

## Loading images

The `GdkPixBuf` class provides a simple mechanism for loading
an image from a file in synchronous and asynchronous fashion.

For GUI applications, it is recommended to use the asynchronous
stream API to avoid blocking the control flow of the application.

Additionally, `GdkPixbuf` provides the [class@GdkPixbuf.PixbufLoader`]
API for progressive image loading.

## Saving images

The `GdkPixbuf` class provides methods for saving image data in
a number of file formats. The formatted data can be written to a
file or to a memory buffer. `GdkPixbuf` can also call a user-defined
callback on the data, which allows to e.g. write the image
to a socket or store it in a database.&lt;/doc&gt;
      &lt;implements name=&quot;Gio.Icon&quot;/&gt;
      &lt;implements name=&quot;Gio.LoadableIcon&quot;/&gt;

             line=&quot;599&quot;&gt;Creates a new `GdkPixbuf` structure and allocates a buffer for it.

If the allocation of the buffer failed, this function will return `NULL`.

The buffer has an optimal rowstride. Note that the buffer is not cleared;
you will have to fill it completely yourself.&lt;/doc&gt;

Since you are providing a pre-allocated pixel buffer, you must also
specify a way to free that data.  This is done with a function of
type `GdkPixbufDestroyNotify`.  When a pixbuf created with is
finalized, your destroy notification function will be called, and
it is its responsibility to free the pixel array.

The image will be scaled to fit in the requested size, optionally preserving
the image&#039;s aspect ratio.

When preserving the aspect ratio, a `width` of -1 will cause the image
to be scaled to the exact given height, and a `height` of -1 will cause
the image to be scaled to the exact given width. When not preserving
aspect ratio, a `width` or `height` of -1 means to not scale the image
at all in that dimension. Negative values for `width` and `height` are
allowed since 2.8.&lt;/doc&gt;

             line=&quot;951&quot;&gt;Creates a `GdkPixbuf` from a flat representation that is suitable for
storing as inline data in a program.

This is useful if you want to ship a program with images, but don&#039;t want
to depend on any external files.

GdkPixbuf ships with a program called `gdk-pixbuf-csource`, which allows
for conversion of `GdkPixbuf`s into such a inline representation.

In almost all cases, you should pass the `--raw` option to
`gdk-pixbuf-csource`. A sample invocation would be:

```
gdk-pixbuf-csource --raw --name=myimage_inline myimage.png
```

For the typical case where the inline pixbuf is read-only static data,
you don&#039;t need to copy the pixel data unless you intend to write to
it, so you can pass `FALSE` for `copy_pixels`. If you pass `--rle` to
`gdk-pixbuf-csource`, a copy will be made even if `copy_pixels` is `FALSE`,
so using this option is generally a bad idea.

If you create a pixbuf from const inline data compiled into your
program, it&#039;s probably safe to ignore errors and disable length checks,
since things will always succeed:

```c
pixbuf = gdk_pixbuf_new_from_inline (-1, myimage_inline, FALSE, NULL);
```

For non-const inline data, you could get out of memory. For untrusted
inline data located at runtime, you could have corrupt inline data in
addition.&lt;/doc&gt;

This is to be used by applications that want to ship certain loaders

This is needed when the OS or runtime ships a minimal number of loaders
so as to reduce the potential attack surface of carefully crafted image
files, especially for uncommon file types. Applications that require
broader image file types coverage, such as image viewers, would be
expected to ship the gdk-pixbuf modules in a separate location, bundled
with the application in a separate directory from the OS or runtime-
provided modules.&lt;/doc&gt;

If the existing pixbuf already had an alpha channel, the channel
values are copied from the original; otherwise, the alpha channel
is initialized to 255 (full opacity).

If `substitute_color` is `TRUE`, then the color specified by the
(`r`, `g`, `b`) arguments will be assigned zero opacity. That is,
if you pass `(255, 255, 255)` for the substitute color, all white
pixels will become fully transparent.

If `substitute_color` is `FALSE`, then the (`r`, `g`, `b`) arguments
will be ignored.&lt;/doc&gt;

the TIFF orientation tag, and compensates it for the partial

This gives an image in the coordinates of the destination pixbuf.
The rectangle (@dest_x, @dest_y, @dest_width, @dest_height)
is then alpha blended onto the corresponding rectangle of the
original destination image.

When the destination rectangle contains parts not in the source
image, the data at the edges of the source image is replicated
to infinity.

The ICO, XBM, and XPM loaders provide &quot;x_hot&quot; and &quot;y_hot&quot; hot-spot
options for cursor definitions. The PNG loader provides the tEXt ancillary
chunk key/value pairs as options. Since 2.12, the TIFF and JPEG loaders
return an &quot;orientation&quot; option string that corresponds to the embedded
TIFF/Exif orientation tag (if present). Since 2.32, the TIFF loader sets
the &quot;multipage&quot; option string to &quot;yes&quot; when a multi-page TIFF is loaded.
Since 2.32 the JPEG and PNG loaders set &quot;x-dpi&quot; and &quot;y-dpi&quot; if the file
contains image density information in dots per inch.
Since 2.36.6, the JPEG loader sets the &quot;comment&quot; option with the comment
EXIF tag.&lt;/doc&gt;

`dest`.

The `src` and `dest` pixbufs must have the same image format, size, and
rowstride.

The `src` and `dest` arguments may be the same pixbuf with no ill effects.

If `saturation` is 1.0 then saturation is not changed. If it&#039;s less than 1.0,
saturation is reduced (the image turns toward grayscale); if greater than
1.0, saturation is increased (the image gets more vivid colors).

If `pixelate` is `TRUE`, then pixels are faded in a checkerboard pattern to
create a pixelated image.&lt;/doc&gt;

             line=&quot;2416&quot;&gt;Saves pixbuf to a file in format @type. By default, &quot;jpeg&quot;, &quot;png&quot;, &quot;ico&quot;
and &quot;bmp&quot; are possible file formats to save in, but more formats may be
installed. The list of all writable formats can be determined in the
following way:

```c
void add_if_writable (GdkPixbufFormat *data, GSList **list)
{
  if (gdk_pixbuf_format_is_writable (data))
    *list = g_slist_prepend (*list, data);
}

GSList *formats = gdk_pixbuf_get_formats ();
GSList *writable_formats = NULL;
g_slist_foreach (formats, add_if_writable, &amp;amp;writable_formats);
g_slist_free (formats);
```

If `error` is set, `FALSE` will be returned. Possible errors include
those in the `GDK_PIXBUF_ERROR` domain and those in the `G_FILE_ERROR`
domain.

The variable argument list should be `NULL`-terminated; if not empty,
it should contain pairs of strings that modify the save
parameters. For example:

```c
gdk_pixbuf_save (pixbuf, handle, &quot;jpeg&quot;, &amp;amp;error, &quot;quality&quot;, &quot;100&quot;, NULL);
```

Currently only few parameters exist.

JPEG images can be saved with a &quot;quality&quot; parameter; its value should be
in the range `[0, 100]`. JPEG and PNG density can be set by setting the
&quot;x-dpi&quot; and &quot;y-dpi&quot; parameters to the appropriate values in dots per inch.

Text chunks can be attached to PNG images by specifying parameters of
the form &quot;tEXt::key&quot;, where key is an ASCII string of length 1-79.
The values are UTF-8 encoded strings. The PNG compression level can
be specified using the &quot;compression&quot; parameter; it&#039;s value is in an
integer in the range of `[0, 9]`.

ICC color profiles can also be embedded into PNG, JPEG and TIFF images.
The &quot;icc-profile&quot; value should be the complete ICC profile encoded
into base64.

```c
char *contents;
gsize length;

// icm_path is set elsewhere
g_file_get_contents (icm_path, &amp;amp;contents, &amp;amp;length, NULL);

char *contents_encode = g_base64_encode ((const guchar *) contents, length);

gdk_pixbuf_save (pixbuf, handle, &quot;png&quot;, &amp;amp;error, &quot;icc-profile&quot;, contents_encode, NULL);
```

TIFF images recognize:

 1. a &quot;bits-per-sample&quot; option (integer) which can be either 1 for saving
    bi-level CCITTFAX4 images, or 8 for saving 8-bits per sample
 2. a &quot;compression&quot; option (integer) which can be 1 for no compression,
    2 for Huffman, 5 for LZW, 7 for JPEG and 8 for DEFLATE (see the libtiff
    documentation and tiff.h for all supported codec values)
 3. an &quot;icc-profile&quot; option (zero-terminated string) containing a base64
    encoded ICC color profile.

ICO images can be saved in depth 16, 24, or 32, by using the &quot;depth&quot;
parameter. When the ICO saver is given &quot;x_hot&quot; and &quot;y_hot&quot; parameters,
it produces a CUR instead of an ICO.&lt;/doc&gt;

This is a convenience function that uses `gdk_pixbuf_save_to_callback()`
to do the real work.

Note that the buffer is not `NUL`-terminated and may contain embedded `NUL`
characters.

If @error is set, `FALSE` will be returned and @buffer will be set to
`NULL`. Possible errors include those in the `GDK_PIXBUF_ERROR`
domain.

@scale_x and @scale_y then translating by @offset_x and @offset_y,
then renders the rectangle (@dest_x, @dest_y, @dest_width,
@dest_height) of the resulting image onto the destination image
replacing the previous contents.

Try to use gdk_pixbuf_scale_simple() first; this function is
the industrial-strength power tool you can fall back to, if
gdk_pixbuf_scale_simple() isn&#039;t powerful enough.

If the source rectangle overlaps the destination rectangle on the
same pixbuf, it will be overwritten during the scaling which
results in rendering artifacts.&lt;/doc&gt;

             line=&quot;236&quot;&gt;Create a new pixbuf containing a copy of `src` scaled to
`dest_width` x `dest_height`.

This function leaves `src` unaffected.

The `interp_type` should be `GDK_INTERP_NEAREST` if you want maximum
speed (but when scaling down `GDK_INTERP_NEAREST` is usually unusably
ugly). The default `interp_type` should be `GDK_INTERP_BILINEAR` which
offers reasonable quality and speed.

You can scale a sub-portion of `src` by creating a sub-pixbuf
pointing into `src`; see [method@GdkPixbuf.Pixbuf.new_subpixbuf].

If `dest_width` and `dest_height` are equal to the width and height of
`src`, this function will return an unscaled copy of `src`.

For more complicated scaling/alpha blending see [method@GdkPixbuf.Pixbuf.scale]
and [method@GdkPixbuf.Pixbuf.composite].&lt;/doc&gt;

These values can be passed to gdk_pixbuf_xlib_render_to_drawable_alpha()

This function can create a bilevel clipping mask (black and white) and use
it while painting the image.

In the future, when the X Window System gets an alpha channel extension,
it will be possible to do full alpha compositing onto arbitrary drawables.

The GdkPixBuf library provides a simple mechanism to load and
represent animations. An animation is conceptually a series of
frames to be displayed over time.

The animation may not be represented as a series of frames
internally; for example, it may be stored as a sprite and
instructions for moving the sprite around a background.

To display an animation you don&#039;t need to understand its
representation, however; you just ask `GdkPixbuf` what should
be displayed at a given point in time.&lt;/doc&gt;

             line=&quot;664&quot;&gt;Get an iterator for displaying an animation.

The iterator provides the frames that should be displayed at a
given time.

@start_time would normally come from g_get_current_time(), and marks
the beginning of animation playback. After creating an iterator, you
should immediately display the pixbuf returned by
gdk_pixbuf_animation_iter_get_pixbuf(). Then, you should install
a timeout (with g_timeout_add()) or by some other mechanism ensure
that you&#039;ll update the image after
gdk_pixbuf_animation_iter_get_delay_time() milliseconds. Each time
the image is updated, you should reinstall the timeout with the new,
possibly-changed delay time.

As a shortcut, if @start_time is `NULL`, the result of
g_get_current_time() will be used automatically.

To update the image (i.e. possibly change the result of
gdk_pixbuf_animation_iter_get_pixbuf() to a new frame of the animation),
call gdk_pixbuf_animation_iter_advance().

If you&#039;re using #GdkPixbufLoader, in addition to updating the image
after the delay time, you should also update it whenever you
receive the area_updated signal and
gdk_pixbuf_animation_iter_on_currently_loading_frame() returns
`TRUE`. In this case, the frame currently being fed into the loader
has received new data, so needs to be refreshed. The delay time for
a frame may also be modified after an area_updated signal, for
example if the delay time for a frame is encoded in the data after
the frame itself. So your timeout should be reinstalled after any
area_updated signal.

             line=&quot;664&quot;&gt;Get an iterator for displaying an animation.

The iterator provides the frames that should be displayed at a
given time.

@start_time would normally come from g_get_current_time(), and marks
the beginning of animation playback. After creating an iterator, you
should immediately display the pixbuf returned by
gdk_pixbuf_animation_iter_get_pixbuf(). Then, you should install
a timeout (with g_timeout_add()) or by some other mechanism ensure
that you&#039;ll update the image after
gdk_pixbuf_animation_iter_get_delay_time() milliseconds. Each time
the image is updated, you should reinstall the timeout with the new,
possibly-changed delay time.

As a shortcut, if @start_time is `NULL`, the result of
g_get_current_time() will be used automatically.

To update the image (i.e. possibly change the result of
gdk_pixbuf_animation_iter_get_pixbuf() to a new frame of the animation),
call gdk_pixbuf_animation_iter_advance().

If you&#039;re using #GdkPixbufLoader, in addition to updating the image
after the delay time, you should also update it whenever you
receive the area_updated signal and
gdk_pixbuf_animation_iter_on_currently_loading_frame() returns
`TRUE`. In this case, the frame currently being fed into the loader
has received new data, so needs to be refreshed. The delay time for
a frame may also be modified after an area_updated signal, for
example if the delay time for a frame is encoded in the data after
the frame itself. So your timeout should be reinstalled after any
area_updated signal.

A delay time of -1 is possible, indicating &quot;infinite&quot;.&lt;/doc&gt;

Chooses the frame based on the start time passed to
gdk_pixbuf_animation_get_iter().

@current_time would normally come from g_get_current_time(), and
must be greater than or equal to the time passed to
gdk_pixbuf_animation_get_iter(), and must increase or remain
unchanged each time gdk_pixbuf_animation_iter_get_pixbuf() is
called. That is, you can&#039;t go backward in time; animations only
play forward.

As a shortcut, pass `NULL` for the current time and g_get_current_time()
will be invoked on your behalf. So you only need to explicitly pass
@current_time if you&#039;re doing something odd like playing the animation
at double speed.

If this function returns `FALSE`, there&#039;s no need to update the animation
display, assuming the display had been rendered prior to advancing;
if `TRUE`, you need to call gdk_pixbuf_animation_iter_get_pixbuf()
and update the display with the new pixbuf.&lt;/doc&gt;

Note that some formats, like GIF, might clamp the timeout values in the
image file to avoid updates that are just too quick. The minimum timeout
for GIF images is currently 20 milliseconds.&lt;/doc&gt;

milliseconds.

The caller of this function does not own a reference to the returned
pixbuf; the returned pixbuf will become invalid when the iterator
advances to the next frame, which may happen anytime you call
gdk_pixbuf_animation_iter_advance().

Copy the pixbuf to keep it (don&#039;t just add a reference), as it may get
recycled as you advance the iterator.&lt;/doc&gt;

             line=&quot;813&quot;&gt;Possibly advances an animation to a new frame.

Chooses the frame based on the start time passed to
gdk_pixbuf_animation_get_iter().

@current_time would normally come from g_get_current_time(), and
must be greater than or equal to the time passed to
gdk_pixbuf_animation_get_iter(), and must increase or remain
unchanged each time gdk_pixbuf_animation_iter_get_pixbuf() is
called. That is, you can&#039;t go backward in time; animations only
play forward.

As a shortcut, pass `NULL` for the current time and g_get_current_time()
will be invoked on your behalf. So you only need to explicitly pass
@current_time if you&#039;re doing something odd like playing the animation
at double speed.

If this function returns `FALSE`, there&#039;s no need to update the animation
display, assuming the display had been rendered prior to advancing;
if `TRUE`, you need to call gdk_pixbuf_animation_iter_get_pixbuf()
and update the display with the new pixbuf.&lt;/doc&gt;

The `g_timeout_add()` function conveniently takes a timeout in milliseconds,
so you can use a timeout to schedule the next update.

Note that some formats, like GIF, might clamp the timeout values in the
image file to avoid updates that are just too quick. The minimum timeout
for GIF images is currently 20 milliseconds.&lt;/doc&gt;

milliseconds.

The caller of this function does not own a reference to the returned
pixbuf; the returned pixbuf will become invalid when the iterator
advances to the next frame, which may happen anytime you call
gdk_pixbuf_animation_iter_advance().

Copy the pixbuf to keep it (don&#039;t just add a reference), as it may get
recycled as you advance the iterator.&lt;/doc&gt;

           line=&quot;34&quot;&gt;Incremental image loader.

`GdkPixbufLoader` provides a way for applications to drive the
process of loading an image, by letting them send the image data
directly to the loader instead of having the loader read the data
from a file. Applications can use this functionality instead of
`gdk_pixbuf_new_from_file()` or `gdk_pixbuf_animation_new_from_file()`
when they need to parse image data in small chunks. For example,
it should be used when reading an image from a (potentially) slow
network connection, or when loading an extremely large file.

To use `GdkPixbufLoader` to load an image, create a new instance,
and call [method@GdkPixbuf.PixbufLoader.write] to send the data
to it. When done, [method@GdkPixbuf.PixbufLoader.close] should be
called to end the stream and finalize everything.

The loader will emit three important signals throughout the process:

 - [signal@GdkPixbuf.PixbufLoader::size-prepared] will be emitted as
   soon as the image has enough information to determine the size of
   the image to be used. If you want to scale the image while loading
   it, you can call [method@GdkPixbuf.PixbufLoader.set_size] in
   response to this signal.
 - [signal@GdkPixbuf.PixbufLoader::area-prepared] will be emitted as
   soon as the pixbuf of the desired has been allocated. You can obtain
   the `GdkPixbuf` instance by calling [method@GdkPixbuf.PixbufLoader.get_pixbuf].
   If you want to use it, simply acquire a reference to it. You can
   also call `gdk_pixbuf_loader_get_pixbuf()` later to get the same
   pixbuf.
 - [signal@GdkPixbuf.PixbufLoader::area-updated] will be emitted every
   time a region is updated. This way you can update a partially
   completed image. Note that you do not know anything about the
   completeness of an image from the updated area. For example, in an
   interlaced image you will need to make several passes before the
   image is done loading.

## Loading an animation

Loading an animation is almost as easy as loading an image. Once the
first [signal@GdkPixbuf.PixbufLoader::area-prepared] signal has been
emitted, you can call [method@GdkPixbuf.PixbufLoader.get_animation] to
get the [class@GdkPixbuf.PixbufAnimation] instance, and then call
and [method@GdkPixbuf.PixbufAnimation.get_iter] to get a
[class@GdkPixbuf.PixbufAnimationIter] to retrieve the pixbuf for the
desired time stamp.&lt;/doc&gt;

             line=&quot;654&quot;&gt;Creates a new pixbuf loader object that always attempts to parse
image data as if it were an image of MIME type @mime_type, instead of
identifying the type automatically.

This function is useful if you want an error if the image isn&#039;t the
expected MIME type; for loading image formats that can&#039;t be reliably
identified by looking at the data; or if the user manually forces a
specific MIME type.

The list of supported mime types depends on what image loaders
are installed, but typically &quot;image/png&quot;, &quot;image/jpeg&quot;, &quot;image/gif&quot;,
&quot;image/tiff&quot; and &quot;image/x-xpixmap&quot; are among the supported mime types.
To obtain the full list of supported mime types, call
gdk_pixbuf_format_get_mime_types() on each of the #GdkPixbufFormat
structs returned by gdk_pixbuf_get_formats().&lt;/doc&gt;

image data as if it were an image of type @image_type, instead of
identifying the type automatically.

This function is useful if you want an error if the image isn&#039;t the
expected type; for loading image formats that can&#039;t be reliably
identified by looking at the data; or if the user manually forces
a specific type.

The list of supported image formats depends on what image loaders
are installed, but typically &quot;png&quot;, &quot;jpeg&quot;, &quot;gif&quot;, &quot;tiff&quot; and
&quot;xpm&quot; are among the supported formats. To obtain the full list of
supported image formats, call gdk_pixbuf_format_get_name() on each
of the #GdkPixbufFormat structs returned by gdk_pixbuf_get_formats().&lt;/doc&gt;

internal loading structures.

This function also tries to parse any data that hasn&#039;t yet been parsed;
if the remaining data is partial or corrupt, an error will be returned.

If `FALSE` is returned, `error` will be set to an error from the
`GDK_PIXBUF_ERROR` or `G_FILE_ERROR` domains.

If you&#039;re just cancelling a load rather than expecting it to be finished,
passing `NULL` for `error` to ignore it is reasonable.

Remember that this function does not release a reference on the loader, so
you will need to explicitly release any reference you hold.&lt;/doc&gt;

In general it only makes sense to call this function after the

to know the size of the image that will be allocated.

If the loader has not received enough data via gdk_pixbuf_loader_write(),
then this function returns `NULL`.

The returned pixbuf will be the same in all future calls to the loader,
so if you want to keep using it, you should acquire a reference to it.

Additionally, if the loader is an animation, it will return the &quot;static
image&quot; of the animation (see gdk_pixbuf_animation_get_static_image()).&lt;/doc&gt;

           line=&quot;50&quot;&gt;A `GdkPixbufModule` contains the necessary functions to load and save
images in a certain file format.

If `GdkPixbuf` has been compiled with `GModule` support, it can be extended
by modules which can load (and perhaps also save) new image and animation
formats.

## Implementing modules

The `GdkPixbuf` interfaces needed for implementing modules are contained in
`gdk-pixbuf-io.h` (and `gdk-pixbuf-animation.h` if the module supports
animations). They are not covered by the same stability guarantees as the
regular GdkPixbuf API. To underline this fact, they are protected by the
`GDK_PIXBUF_ENABLE_BACKEND` pre-processor symbol.

Each loadable module must contain a `GdkPixbufModuleFillVtableFunc` function
named `fill_vtable`, which will get called when the module
is loaded and must set the function pointers of the `GdkPixbufModule`.

In order to make format-checking work before actually loading the modules
(which may require calling `dlopen` to load image libraries), modules export
their signatures (and other information) via the `fill_info` function. An
external utility, `gdk-pixbuf-query-loaders`, uses this to create a text
file containing a list of all available loaders and  their signatures.
This file is then read at runtime by `GdkPixbuf` to obtain the list of
available loaders and their signatures.

Modules may only implement a subset of the functionality available via
`GdkPixbufModule`. If a particular functionality is not implemented, the
`fill_vtable` function will simply not set the corresponding
function pointers of the `GdkPixbufModule` structure. If a module supports
incremental loading (i.e. provides `begin_load`, `stop_load` and
`load_increment`), it doesn&#039;t have to implement `load`, since `GdkPixbuf`
can supply a generic `load` implementation wrapping the incremental loading.

## Installing modules

Installing a module is a two-step process:

 - copy the module file(s) to the loader directory (normally
   `$libdir/gdk-pixbuf-2.0/$version/loaders`, unless overridden by the
   environment variable `GDK_PIXBUF_MODULEDIR`)
 - call `gdk-pixbuf-query-loaders` to update the module file (normally
   `$libdir/gdk-pixbuf-2.0/$version/loaders.cache`, unless overridden
   by the environment variable `GDK_PIXBUF_MODULE_FILE`)&lt;/doc&gt;

           line=&quot;170&quot;&gt;The signature prefix for a module.

The signature of a module is a set of prefixes. Prefixes are encoded as
pairs of ordinary strings, where the second string, called the mask, if
not `NULL`, must be of the same length as the first one and may contain
&#039; &#039;, &#039;!&#039;, &#039;x&#039;, &#039;z&#039;, and &#039;n&#039; to indicate bytes that must be matched,
not matched, &quot;don&#039;t-care&quot;-bytes, zeros and non-zeros, respectively.

Each prefix has an associated integer that describes the relevance of
the prefix, with 0 meaning a mismatch and 100 a &quot;perfect match&quot;.

Starting with gdk-pixbuf 2.8, the first byte of the mask may be &#039;*&#039;,
indicating an unanchored pattern that matches not only at the beginning,
but also in the middle. Versions prior to 2.8 will interpret the &#039;*&#039;
like an &#039;x&#039;.

The signature of a module is stored as an array of
`GdkPixbufModulePatterns`. The array is terminated by a pattern
where the `prefix` is `NULL`.

```c
GdkPixbufModulePattern *signature[] = {
  { &quot;abcdx&quot;, &quot; !x z&quot;, 100 },
  { &quot;bla&quot;, NULL,  90 },
  { NULL, NULL, 0 }
};
```

In the example above, the signature matches e.g. &quot;auud\0&quot; with
relevance 100, and &quot;blau&quot; with relevance 90.&lt;/doc&gt;

The function is expected to set @width and @height to the desired
size to which the image should be scaled. If a module has no efficient
way to achieve the desired scaling during the loading of the image, it may
either ignore the size request, or only approximate it - gdk-pixbuf will
then perform the required scaling on the completely loaded image.

If the function sets @width or @height to zero, the module should interpret
this as a hint that it will be closed soon and shouldn&#039;t allocate further
resources. This convention is used to implement gdk_pixbuf_get_file_info()
efficiently.&lt;/doc&gt;
