|
||||
Here are some ideas under discussion for the next major revision of
|
||||
the SANE API:
|
||||
|
||||
o Additional image data types, such as JPEG, MPEG, FlashPix, raw.
|
||||
These would be useful for devices that directly generate such
|
||||
formats (still cameras, for example). The raw image format could
|
||||
be used when no other format is applicable. This would allow to
|
||||
at least read and save the data in a file. This would probably
|
||||
have to be coupled with adding a function that lets a frontend
|
||||
tell the backend what level it supports, something like
|
||||
sane_set_level (int max_supported_level).
|
||||
[Based on suggestion by Andreas Beck <becka@charon.rz.beck-sw.de>]
|
||||
|
||||
o Support for other multimedia types, such as audio. This probably
|
||||
would also require adding a write() interface to the SANE API.
|
||||
[Suggested by Erik Troan <ewt@redhat.com>.]
