<summary>Contains functions for inlined pixbuf handling. It allows for pixbuf data to be accessed in a raw form, serialized, and stored.</summary>
|
|
<remarks>At the time of this writing, gtk-sharp 0.98 has a bug where <see cref="M:Gdk.Pixdata.Serialize" /> and <see cref="M:Gdk.Pixdata.Deserialize" /> use <see cref="T:System.Byte" /> where Byte [] should be used making them function improperly. This problem should be fixed in a future release.</remarks>
