Pixbuf.this

gdkpixbuf Pixbuf Pixbuf

Creates a new pixbuf by loading an image from an input stream.

The file format is detected automatically. If NULL is returned, then error will be set. The cancellable can be used to abort the operation from another thread. If the operation was cancelled, the error G_IO_ERROR_CANCELLED will be returned. Other possible errors are in the GDK_PIXBUF_ERROR and G_IO_ERROR domains.

The stream is not closed.

Parameters

stream InputStream

a gio.InputStream to load the pixbuf from

cancellable Cancellable

optional gio.Cancellable object, NULL to ignore

Return Value

A newly-created pixbuf, or NULL if any of several error conditions occurred: the file could not be opened, the image format is not supported, there was not enough memory to allocate the image buffer, the stream contained invalid data, or the operation was cancelled.

Throws

GException on failure. ConstructionException GTK+ fails to create the object.
