File saving

gdk_pixbuf_savev ()

gboolean    gdk_pixbuf_savev                (GdkPixbuf *pixbuf,
                                             const char *filename,
                                             const char *type,
                                             char **option_keys,
                                             char **option_values,
                                             GError **error);

Saves pixbuf to a file in type, which is currently "jpeg" or "png". If error is set, FALSE will be returned. See gdk_pixbuf_save() for more details.

gdk_pixbuf_save ()

gboolean    gdk_pixbuf_save                 (GdkPixbuf *pixbuf,
                                             const char *filename,
                                             const char *type,
                                             GError **error,
                                             ...);

Saves pixbuf to a file in type, which is currently "jpeg" or "png". 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]. 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.
