Declaration [src]

gboolean
gdk_pixbuf_save_to_buffer (
  GdkPixbuf* pixbuf,
  gchar** buffer,
  gsize* buffer_size,
  const char* type,
  GError** error,
  ...
)

Description [src]

Saves pixbuf to a new buffer in format type, which is currently “jpeg”, “png”, “tiff”, “ico” or “bmp”.

This is a convenience function that uses gdk_pixbuf_save_to_callback() to do the real work.

Note that the buffer is not NUL-terminated and may contain embedded NUL characters.

If error is set, FALSE will be returned and buffer will be set to NULL. Possible errors include those in the GDK_PIXBUF_ERROR domain.

See gdk_pixbuf_save() for more details.

Available since: 2.4
