        <doc xml:whitespace="preserve">Create 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't want to depend on any
external files.
gdk-pixbuf ships with a program called &lt;command&gt;gdk-pixbuf-csource&lt;/command&gt; 
which allows for conversion of #GdkPixbufs into such a inline representation.
In almost all cases, you should pass the &lt;option&gt;--raw&lt;/option&gt; flag to
&lt;command&gt;gdk-pixbuf-csource&lt;/command&gt;. A sample invocation would be:
&lt;informalexample&gt;&lt;programlisting&gt;
gdk-pixbuf-csource --raw --name=myimage_inline myimage.png
&lt;/programlisting&gt;&lt;/informalexample&gt;
For the typical case where the inline pixbuf is read-only static data,
you don'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 
&lt;option&gt;--rle&lt;/option&gt; to &lt;command&gt;gdk-pixbuf-csource&lt;/command&gt;, 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's probably safe to ignore errors and disable length checks, 
since things will always succeed:
&lt;informalexample&gt;&lt;programlisting&gt;
pixbuf = gdk_pixbuf_new_from_inline (-1, myimage_inline, FALSE, NULL);
&lt;/programlisting&gt;&lt;/informalexample&gt;
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.

and "bmp" 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:
|[
void add_if_writable (GdkPixbufFormat *data, GSList **list)
{
if (gdk_pixbuf_format_is_writable (data))
*list = g_slist_prepend (*list, data);

GSList *writable_formats = NULL;
g_slist_foreach (formats, add_if_writable, &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:
&lt;informalexample&gt;&lt;programlisting&gt;
gdk_pixbuf_save (pixbuf, handle, "jpeg", &amp;amp;error,
"quality", "100", NULL);
&lt;/programlisting&gt;&lt;/informalexample&gt;
Currently only few parameters exist. JPEG images can be saved with a
"quality" parameter; its value should be in the range [0,100].
Text chunks can be attached to PNG images by specifying parameters of
the form "tEXt::key", 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 "compression" parameter; it's value is in an
integer in the range of [0,9].
ICC color profiles can also be embedded into PNG and TIFF images.
The "icc-profile" value should be the complete ICC profile encoded
into base64.
&lt;informalexample&gt;&lt;programlisting&gt;
gchar *contents;
gchar *contents_encode;
gsize length;
g_file_get_contents ("/home/hughsie/.color/icc/L225W.icm", &amp;contents, &amp;length, NULL);
contents_encode = g_base64_encode ((const guchar *) contents, length);
gdk_pixbuf_save (pixbuf, handle, "png", &amp;amp;error,
"icc-profile", contents_encode,
NULL);
&lt;/programlisting&gt;&lt;/informalexample&gt;
TIFF images recognize a "compression" option which acceps an integer value.
Among the codecs are 1 None, 2 Huffman, 5 LZW, 7 JPEG and 8 Deflate, see
the libtiff documentation and tiff.h for all supported codec values.
ICO images can be saved in depth 16, 24, or 32, by using the "depth"
parameter. When the ICO saver is given "x_hot" and "y_hot" parameters,
it produces a CUR instead of an ICO.</doc>

unchanged each time gdk_pixbuf_animation_iter_get_pixbuf() is

play forward.

at double speed.
If this function returns %FALSE, there's no need to update the animation
display, assuming the display had been rendered prior to advancing;
if %TRUE, you need to call gdk_animation_iter_get_pixbuf() and update the
display with the new pixbuf.</doc>
