TIcon reads and writes .ICO file format.
A .ico file typically contains several versions of the same image.
When loading, the largest/most colourful image is loaded as the TBitmap and so can be handled as any other bitmap. Any other versions of the images are available via the Bitmaps property
Writing is not (yet) implemented.
