DjVu / Поворот страниц в Djvu
« : 23 ёоЭм 2013, 10:25:13 »
Цифруя книги в djvu, мне понадобилась функция поворота страницы в djvu файле на угол 90 градусов. С этой задачей справляется DEEditor, но мне нужна была именно консольная програмка. Решил написать Leon Bottou и получил оперативный ответ:

Done in the git repository.
Program 'djvused' has now a command
set-rotation [+-]rot
that changes the default page orientation. The orientation is expressed as
an integer in range 0..3 representing a number of 90 degree counter-clockwise
rotations. When the argument is preceded by a sign + or -, argument rot
counts how many additional 90 degree counter-clockwise rotations should be
applied to the page. Otherwise, argument rot represents the desired absolute
page orientation. Only DjVu pages can be rotated. Pages represented as a
raw IW44 image cannot be rotated.
For instance, to rotate all pages clockwise, you can write
% djvused foo.djvu -e 'set-rotation -1' -s
and to change only the orientation of the first page
% djvused foo.djvu -e 'select 1; set-rotation -1' -s
- L.
