TWAIN: Implement support for frame options
TWAIN: Implement support for frame options:
TWAIN provides and gets the coordinates of the scan to do as a single structure: TW_FRAME
(which 4 doubles inside (TW_FIX32
)). But when using Libinsane, we want them as 4 separate options (tl-x
, tl-y
, br-x
, br-y
), just as Sane provides them.
