bitmap-dc%

A bitmap-dc% object allows drawing direclty into a bitmap. A bitmap% object must be supplied at initialization or installed into a bitmap DC using set-bitmap before any other method of the DC is called. If a bitmap-dc% method is called before a bitmap is selected, the method call is ignored.

• (make-object bitmap-dc% bm) -> bitmap-dc% object
      bm : bitmap% object or #f

  Creates a new memory DC. If bm is not #f, it is installed into the DC so that drawing commands on the DC draw to bm. Otherwise, no bitmap is installed into the DC and set-bitmap must be called before any other method of the DC is called.
