line="931">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 [gdk-pixbuf-csource][gdk-pixbuf-csource],
which allows for conversion of #GdkPixbufs 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'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's probably safe to ignore errors and disable length checks,
since things will always succeed:
|[
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.</doc>

]|
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:
|[
gdk_pixbuf_save (pixbuf, handle, "jpeg", &error, "quality", "100", NULL);
]|
Currently only few parameters exist. JPEG images can be saved with a
"quality" parameter; its value should be in the range [0,100]. JPEG
and PNG density can be set by setting the "x-dpi" and "y-dpi" parameters
to the appropriate values in dots per inch.
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, JPEG and TIFF images.
The "icc-profile" value should be the complete ICC profile encoded
into base64.
|[
gchar *contents;
gchar *contents_encode;
gsize length;
g_file_get_contents ("/home/hughsie/.color/icc/L225W.icm", &contents, &length, NULL);
contents_encode = g_base64_encode ((const guchar *) contents, length);
gdk_pixbuf_save (pixbuf, handle, "png", &error, "icc-profile", contents_encode, NULL);
]|
TIFF images recognize: (1) a "bits-per-sample" option (integer) which
can be either 1 for saving bi-level CCITTFAX4 images, or 8 for saving
8-bits per sample; (2) a "compression" 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 "icc-profile" 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 "depth"
parameter. When the ICO saver is given "x_hot" and "y_hot" parameters,
it produces a CUR instead of an ICO.</doc>

scaling down #GDK_INTERP_NEAREST is usually unusably ugly). The

reasonable quality and speed.
You can scale a sub-portion of @src by creating a sub-pixbuf
pointing into @src; see gdk_pixbuf_new_subpixbuf().
If @dest_width and @dest_height are equal to the @src width and height, a
copy of @src is returned, avoiding any scaling.

the frames that should be displayed at a given time. It should be
freed after use with g_object_unref().
@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'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'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 "infinite."</doc>
