A musical document is usually made of several
pages. Each page is stored in an independent file. Names of these pages
are stored in an OMeR file, with "lsf" extension
(List of Scan Files).

it reverses it (black symbols on white background are necessary for your
page to be processed).
• Rotate : if your page hasn't be scanned in the right direction,
you can rotate it.
• Dust removal : erases little dots which can disturb recognition.
Dust removal strength can be adjusted.
• Threshold : if your page has been
scanned in color or gray levels, defines from which value gray is considered
as black. Threshold level can be adjusted.
• Erase margins : if black areas are surrounding your picture,
erases them. Erased area appears in light yellow.
These options are stored in the "lsf" document and applied to page before
being processed. Processing result is showed in the main window. Since
these options are applied each time page picture is loaded, they can noticeably
slow down OMeR.
