With this release of GrapeCity Documents for Imaging (GcImaging), Icon images (those images used on Windows OS for small-sized images) can now be loaded, modified, and saved with GcImaging through the new GcIco class. The image can be generated with multiple frames by setting values for IcoFrame class with different encodings specified through the IcoFrameEncoding enum.
