1.1.2 Bitmap output streams

A bitmap output stream is a stream that sends output to a specified bitmap. To perform stream character output operations on a bitmap, you must attach a bitmap output stream to the bitmap and send the character output to the stream. Stream graphics operations can also be used with bitmap output streams.

When associated with a bitmap, a bitmap output stream maintains an output position that specifies the next available position for writing character output to the bitmap. The bitmap output stream also maintains a current font and a current linefeed distance. The linefeed distance of a stream is initially the character height of the initial font. All of these stream attributes can be modified.
