The Be Book - Classes And Methods - The Translation Kit
| Class Overview |
BBitmapStream(BBitmap* map = NULL);Creates a new instance of BBitmapStream.
If map is NULL, the stream is
initialized to be empty. Otherwise, the
BBitmap
is converted to a translator bitmap and placed in the stream. The application shares the
BBitmap
with the BBitmapStream object. It therefore shouldn't delete the
BBitmap
without first calling
DetachBitmap().
status_t DetachBitmap(BBitmap** outMap);Returns, in outMap, a
BBitmap
representing the image contained in the
BBitmapStream. Once DetachBitmap()
has been called, no further operations
should be performed on the BBitmapStream.

int32 whence);status_t SetSize(off_t size) const;ssize_t WriteAt(off_t pos,
const void* data,
size_t size);These methods provide the implementation for the
BPositionIO.
The class functions identically to
BPositionIO
with the exception of
ReadAt() and
WriteAt(),
which read and write only translator bitmaps as described in
the class introduction.
