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.
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:
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. Note however that PNG text chunks are stored in ISO-8859-1 encoding, so you can only set texts that can be represented in this encoding.
