Create a new GdkPixbuf.PixbufLoader

Parameters:

Object properties

Create a new GdkPixbuf.PixbufLoader

Parameters:

String mime_type Required (not null)

the mime type to be loaded

Returns:

GdkPixbuf.PixbufLoader A newly-created pixbuf loader.

Create a new GdkPixbuf.PixbufLoader

Parameters:

String image_type Required (not null)

name of the image format to be loaded with the image

Returns:

GdkPixbuf.PixbufLoader A newly-created pixbuf loader.

Informs a pixbuf loader that no further writes with
gdk_pixbuf_loader_write() will occur, so that it can free its
internal loading structures. Also, tries to parse any data that
hasn'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're just cancelling a load rather than expecting it
to be finished, passing NULL for error to ignore it is
reasonable.
Remember that this does not unref the loader, so if you plan not to
use it anymore, please g_object_unref() it.

Returns:

gboolean TRUE if all image data written so far was successfully

Queries the GdkPixbufAnimation that a pixbuf loader is currently creating.
In general it only makes sense to call this function after the "area-prepared"
signal has been emitted by the loader. If the loader doesn't have enough
bytes yet (hasn't emitted the "area-prepared" signal) this function will
return NULL.

Returns:

GdkPixbuf.PixbufAnimation The GdkPixbufAnimation that the loader is loading, or NULL if

Obtains the available information about the format of the
currently loading image file.
by GdkPixbuf and should not be freed.

Returns:

GdkPixbuf.PixbufFormat A GdkPixbufFormat or NULL. The return value is owned

Queries the GdkPixbuf that a pixbuf loader is currently creating.
In general it only makes sense to call this function after the
"area-prepared" signal has been emitted by the loader; this means
that enough data has been read 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 simply calling g_object_ref() should be sufficient to continue
using it. Additionally, if the loader is an animation, it will
return the "static image" of the animation
(see gdk_pixbuf_animation_get_static_image()).
enough data has been read to determine how to create the image buffer.

Returns:

GdkPixbuf.Pixbuf The GdkPixbuf that the loader is creating, or NULL if not

Causes the image to be scaled while it is loaded. The desired
image size can be determined relative to the original size of
the image by calling gdk_pixbuf_loader_set_size() from a
signal handler for the ::size-prepared signal.
Attempts to set the desired image size are ignored after the
emission of the ::size-prepared signal.

Parameters:

gint32 width Required (not null)

The desired width of the image being loaded.

gint32 height Required (not null)

The desired height of the image being loaded.

Returns:

none

This will cause a pixbuf loader to parse the next count bytes of
an image. It will return TRUE if the data was loaded successfully,
and FALSE if an error occurred. In the latter case, the loader
will be closed, and will not accept further writes. If FALSE is
returned, error will be set to an error from the GDK_PIXBUF_ERROR
or G_FILE_ERROR domains.
cannot parse the buffer.

Parameters:

String buf Required (not null)

Pointer to image data.

guint32 count Required (not null)

Length of the buf buffer in bytes.

Returns:

gboolean TRUE if the write was successful, or FALSE if the loader

This signal is emitted when the pixbuf loader has allocated the
pixbuf in the desired size. After this signal is emitted,
applications can call gdk_pixbuf_loader_get_pixbuf() to fetch
the partially-loaded pixbuf.

Parameters:

GdkPixbuf.PixbufLoader self

Returns:

{none}

This signal is emitted when a significant area of the image being
loaded has been updated. Normally it means that a complete
scanline has been read in, but it could be a different area as
well. Applications can use this signal to know when to repaint
areas of an image that is being loaded.

Parameters:

GdkPixbuf.PixbufLoader self

gint32 x

gint32 y

gint32 width

gint32 height

Returns:

{none}

This signal is emitted when gdk_pixbuf_loader_close() is called.
It can be used by different parts of an application to receive
notification when an image loader is closed by the code that
drives it.

Parameters:

GdkPixbuf.PixbufLoader self

Returns:

{none}

This signal is emitted when the pixbuf loader has been fed the
initial amount of data that is required to figure out the size
of the image that it will create. Applications can call
gdk_pixbuf_loader_set_size() in response to this signal to set
the desired size to which the image should be scaled.

Parameters:

GdkPixbuf.PixbufLoader self

gint32 width

gint32 height

Returns:

{none}
