Treat binary data as a file object?
Question:
In this code snippet (authored by another person), self.archive is a path to a large file and raw_file is the contents of the file read as binary data.
with open(self.archive, "rb") as f:
f.seek(offset)
raw_file = start + f.read(dlen - len(start))
...
f.write(raw_file)
This archive file contains stored image files, and I’d like to access them pygame.image.load which requires a File object. But I need to do something like pygame.image.load(toVirtualFileObject(raw_file)) (i.e. access this archive file’s contents as File objects without writing to disk first).
Can this be done?
Answers:
This is what StringIO (in Python 2) and io.BytesIO in (in Python 3) are for.
