Draft :

Current Scanner implementation is .. hmm

Improve it is mandatory

Todo: analyse current implementation

Todo

document the existing extensions/source/scanner implementation

define tasks in the Team: (ericb, valeuf, Dyrcona )

document everything

play with Image Capture SDK : create a little application,

test all features

design: classes, naming conventions, API description

define OpenOffice.org source code changes for new scanmacosx.cxx file, and it's compilation

file an issue about the new feature

define new specs

create a cws : explain the steps

start with new implementation (code and debug )

define tests to validate new features

Agenda

**Imprpove Scanner Use on Mac OS X**

Write specs

Current design in OpenOffice.org

OpenOffice.org code location

extensions/source/scanner

[FIXME]: Twain interface should work on Mac OS X version of OpenOffice.org, and configure does accept

--with-system-sane
--with-sane-headers

command line options. Tests scheduled

Products built

All : scanner , scnserv

Windows( WNT) : scanwin

Other ( UNX or OS2 ) :

sane, sandlg scanunx and grid

Code documentation

See OpenOffice.org extensions/source/scanner source code documentation

Contains:

Class description
Methods description
some diagrams (inheritance)
source code

important: the documentation above has been generated using Doxygen, made with current code (from DEV300_m0)

Does not contain : libscn generation + build process, and Design about the Mac OS X lib

(FIXME )

scanner.cxx: uses libsane (3rd part library, must be installed separately). All system calls in libscn extension, are using SANE macros constants, while Apple does provide Twain blob for all scanners.

grid.* : defines the look of the dialog box + the implementation.

To be done: thre is an existing Image Capture device, using Twain on Mac OS X. The idea is to bind with Image Capture device instead of the heavy SANE thing.

The Apple Image Capture SDK does contain code sample ( Model View Controler paradigm in objective C ( to be modified in objc++ )
