Scanimage를 이용한 스캐닝..

1.
조금 오래되었지만 삼성 복합기를 사용하고 있습니다. 거래를 위해 스캔작업이 필요한 경우가 의외로 많습니다. 이 때마다 오피스전문점에서 돈을 주고 스캔하는 비용이 작지 않았서 복합기로 바꾸었습니다. Elementary OS를 사용하고 있기때문에 스캔작업을 위한 프로그램을 찾았습니다.

Simple Scan와 gscan2pdf를 설치하여 사용했는데 몇 번 사용하다가 오류가 발생하였습니다. 설치한 드라이버는 삼성 SCX-4600 레이저 다기능 프린터 시리즈입니다. 증상은 디바이스인식입니다.

여러번 해보았지만 실패해서 결국 Virtual Machine에 설치한 윈도우에서 작업을 하였습니다. 어제 스캔해서 고객에서 문서를 보낼 일이 있어서 혹시나 하는 마음으로 검색을 해보니까 재미있는 글이 눈에 들어왔습니다.

Scanning with a samsung 4600 in ubuntu

특별히 기대를 하지 않고 scanimage를 터미날에서 실행하였습니다.

smallake@elementaryOS:~$ scanimage -L
device `xerox_mfp:libusb:003:003' is a Samsung Samsung SCX-4600 Series multi-function peripheral

1 2	smallake@elementaryOS:~$ scanimage -L device `xerox_mfp:libusb:003:003' is a Samsung Samsung SCX-4600 Series multi-function peripheral

오! 망설림없이 디바이스를 찾네요. 그래서 기대를 갖고 스캔을 실행하였습니다. 복합기에서 소리가 납니다.

scanimage --format=png > /tmp/document.png

1	scanimage --format=png > /tmp/document.png

해당 위치를 확인하니 원하던 문서가 있네요.

scanimage를 좀더 확인해습니다.

우선 명령어의 도움말을 확인했습니다. 명령어뿐 아니라 디바이스와 관련한 정보도 볼 수 있습니다.

smallake@elementaryOS:~$ scanimage -h
Usage: scanimage [OPTION]...

Start image acquisition on a scanner device and write image data to
standard output.

Parameters are separated by a blank from single-character options (e.g.
-d epson) and by a "=" from multi-character options (e.g. --device-name=epson).
-d, --device-name=DEVICE   use a given scanner device (e.g. hp:/dev/scanner)
    --format=pnm|tiff|png|jpeg|pdf  file format of output file
-i, --icc-profile=PROFILE  include this ICC profile into TIFF file
-L, --list-devices         show available scanner devices
-f, --formatted-device-list=FORMAT similar to -L, but the FORMAT of the output
                           can be specified: %d (device name), %v (vendor),
                           %m (model), %t (type), %i (index number), and
                           %n (newline)
-b, --batch[=FORMAT]       working in batch mode, FORMAT is `out%d.pnm' `out%d.tif'
                           `out%d.png' or `out%d.jpg' by default depending on --format
                           This option is incompatible with --output-file.    --batch-start=#        page number to start naming files with
    --batch-count=#        how many pages to scan in batch mode
    --batch-increment=#    increase page number in filename by #
    --batch-double         increment page number by two, same as
                           --batch-increment=2
    --batch-print          print image filenames to stdout
    --batch-prompt         ask for pressing a key before scanning a page
    --accept-md5-only      only accept authorization requests using md5
-p, --progress             print progress messages
-o, --output-file=PATH     save output to the given file instead of stdout.
                           This option is incompatible with --batch.
-n, --dont-scan            only set options, don't actually scan
-T, --test                 test backend thoroughly
-A, --all-options          list all available backend options
-h, --help                 display this help message and exit
-v, --verbose              give even more status messages
-B, --buffer-size=#        change input buffer size (in kB, default 32)
-V, --version              print version information
Output format is not set, using pnm as a default.

  Standard:
    --resolution 75|100|150|200|300|600dpi [150]
        Sets the resolution of the scanned image.
    --mode Lineart|Halftone|Gray|Color [Color]
        Selects the scan mode (e.g., lineart, monochrome, or color).
    --highlight 30..70% (in steps of 10) [inactive]
        Select minimum-brightness to get a white point
    --source Flatbed|ADF|Auto [Flatbed]
        Selects the scan source (such as a document-feeder).
  Geometry:
    -l 0..215.9mm (in steps of 1) [0]
        Top-left x position of scan area.
    -t 0..297.18mm (in steps of 1) [0]
        Top-left y position of scan area.
    -x 0..215.9mm (in steps of 1) [215.9]
