== Panorama Tool - Hiding binaries details ==
* Brief explanation : The goal is to hide the external binaries table when all the binaries are found on the system. A "Binaries' Details" button should be added, which upon clicked will show the table. If all the binaries are not found on start-up, then, the table should be shown by default (can be done by simply generating a pseudo click on the above described button once its implemented). Once it is successfully implemented here, it can be extended to all kipi-plugins which use external binaries.

* Brief explanation: In some users case relevant of photo workflow, as Panorama assembly for example, digiKam need an algorithm to detect black hole borders of image and crop it automatically, respecting the most largest suitable image area. No adjustment must be require by end user. As JPEG is the most used image format used in photography and as JPEG library support a loss-less crop feature, a specific way must be implemented to process JPEG crop in batch without to lose image quality.

Students and mentors will use [https://mail.kde.org/mailman/listinfo/digikam-soc-devel digikam-soc-devel at kde dot org] mailing-list to coordinate projects.
 
= Repositories, Branching, and Dates =
 
== Developer Account ==
 
To be able to code and work on '''digiKam project''', each student must ask for a developer account to KDE Git repository administrator. See [http://techbase.kde.org/Contribute/Get_a_Contributor_Account this page for details] about KDE developers rules.
 
For '''Exiv2 project''', please contact your mentor to get write access on Subversion repository.
 
== Coverity Analyzer Account ==
 
digiKam and Exiv2 have registred in [http://scan2.coverity.com/ Coverty Scan Program] to report all source code dysfunctions. Code is parsed automatically through a cronned script each week end. Reports are forwarded to digikam-soc-devel_at_kde_dot_org mailing-list.
 
To be able to review and fix errors reported by Scan analyzer, all students must be registered in the relevant Coverity project :
 
* [http://scan2.coverity.com/projects/285 digiKam]
* [http://scan2.coverity.com/projects/297 Exiv2]
 
== KDE Repository ==


* Bugzilla entry : https://bugs.kde.org/show_bug.cgi?id=164442
All students working on digiKam will play with KDE Git repository from Git master branch.
* Assigned to : ???
* Note : an initial patch for Advanced Search tool GUI have been posted and must be adapted to last code from git/master. But DB queries builder is not patched and need to be done.


== Add OLYMPUS M.14-42mm F3.5-5.6 II R lens support ==
We have a [https://projects.kde.org/projects/extragear/graphics/digikam/digikam-software-compilation digiKam Software Compilation Repository] where you will be able to checkout all sub-repositories including all shared libraries managed by team. This not included [http://www.exiv2.org/download.html Exiv2] which is hosted outside KDE.


* Bugzilla entry : https://bugs.kde.org/show_bug.cgi?id=311295
Students must have configured KDE developer account and checkout all code from KDE repository using SSH method.
* Patch to review : http://git.reviewboard.kde.org/r/109017/
* Assigned to : ???


== Auto-Detected Camera are Unsuitable ==
Instructions to checkout and compile code is given in [https://projects.kde.org/projects/extragear/graphics/digikam/digikam-software-compilation/repository/revisions/master/raw/README this README file].


* Bugzilla entry : https://bugs.kde.org/show_bug.cgi?id=311393
== Branches Creation and Maintenance ==
* Assigned to : ???


= digiKam Google Summer of Code 2013 Proposals =
During GSoC 2013 coding time, git/master will still the stable implementation receiving important fixes. Each students must create a dedicated development branch for each project (your branch name is defined in project list by "Working on" property). In charge for each students to sync it with git/master periodically. To do it, see below as example how to sync digiKam "MY_DEVEL_BRANCH" branch tracking "remotes/origin/development/MY_DEVEL_BRANCH" from KDE git repository:


== Auto Crop Tool ==
<source lang="bash">
$>git checkout master
$>git pull --rebase
$>git checkout -b MY_DEVEL_BRANCH remotes/origin/development/MY_DEVEL_BRANCH
  Branch MY_DEVEL_BRANCH set up to track remote branch development/MY_DEVEL_BRANCH from origin.
  Switched to a new branch 'MY_DEVEL_BRANCH'
$>git merge master
  Merge made by the 'recursive' strategy.
  ...
$>git push
</source>


* '''Brief explanation:''' In some users case relevant of photo workflow, as Panorama assembly for example, digiKam need an algorithm to detect black hole borders of image and crop it automatically, respecting the most largest suitable image area. No adjustment must be require by end user. As JPEG is the most used image format used in photography and as JPEG library support a loss-less crop feature, a specific way must be implemented to process JPEG crop in batch without to lose image quality.
* '''Dependencies:''' Batch Queue Manager, Image Editor.
* '''Bugzilla entries:''' [https://bugs.kde.org/show_bug.cgi?id=267436 267436], [https://bugs.kde.org/show_bug.cgi?id=204135 204135]
* '''Knowledge Prerequisite:''' C/C++, Qt, Imagery
* '''Expected results:''' new editor and batch queue manager tools to crop automatically images
* '''Difficulty:''' medium
* '''Lead Mentor:''' ???
* '''Alternative Mentor:''' Gilles Caulier <caulier dot gilles at gmail dot com>


== Tags Manager ==
The 2 first lines take a sure that your local master repository is up to date.
The 3rd line create in local the "MY_DEVEL_BRANCH" development branch.
Merge between master and MY_DEVEL_BRANCH branch is done with 4th line. Git can ask you to resolve conflicts here. When it's done, it will ask you a commit comment.
Finally push your merge into remote KDE repository.


* '''Brief explanation:''' Moving tags around in the small tags views from right or left digiKam sidebar can be fastidious, especially with a huge collection of items. A new dedicated windows must be created to manage all tags and relevant properties hosted by digiKam database. This tool must support drag and drop, multiple selections, copy/move operations, properties edition and duplication.
Note: If you have already created MY_DEVEL_BRANCH branch, just run "git checkout MY_DEVEL_BRANCH" as well instead git checkout -b MY_DEVEL_BRANCH remotes/origin/development/MY_DEVEL_BRANCH. This give this concatenated command line:
* '''Dependencies:''' : digiKam core implementation
* '''Bugzilla entries:''' [https://bugs.kde.org/show_bug.cgi?id=263299 263299]
* '''Knowledge Prerequisite:''' C/C++, Qt/KDE, GUI

* '''Difficulty:''' medium
* '''Lead Mentor:''' Smit Metha  <smit dot meh at gmail dot com>
* '''Alternative Mentor:''' Gilles Caulier  <caulier dot gilles at gmail dot com>


== HDR Composer ==
<source lang="bash">
$>git checkout master; git pull --rebase; git checkout MY_DEVEL_BRANCH; git pull; git merge master
  ...
$>git push
</source>


* '''Brief explanation:'''  digiKam already include a tool to make pseudo HDR image through ExpoBlending tool, based on align_image_stack and enfuse programs from Hugin project. This tool is limited to improve a litlle bit exposure latitude of images. It has creativity limitations and cannot reproduce nice HDR images, as Luminance HDR do. The goal of this project is to extend current ExpoBlending tool to add new advanced HDR worklflow. Also, some GUI improvment need to be done to be able to process more that on set of bracketing shots at the same time.
* '''Bugzilla entries:''' [https://bugs.kde.org/show_bug.cgi?id=275364 275364], [https://bugs.kde.org/show_bug.cgi?id=273254 273254]
* '''Dependencies:''' ExpoBlending tool
* '''Knowledge Prerequisite:''' C/C++, Qt, Imagery, math
* '''Expected results:''' new tool to perform high quality HDR composing
* '''Difficulty:''' high
* '''Lead Mentor:''' ???
* '''Alternative Mentor:''' Gilles Caulier  <caulier dot gilles at gmail dot com>


== Cloud Integration Export Plugin ==
For advanced rules, especially to create remote working branches in KDE git repository, please look on [http://techbase.kde.org/Development/Git/Recipes#Creating_.2F_Deleting_Remote_Branches this tutorial] from KDE TechBase.


* '''Brief explanation:'''  Creating a kipi export plugin for putting the pictures on cloud storage devices like Google Drive, DropBox, Skydrive, etc. Depends on the availability of an open source API. For any cloud storage facility, there are two possibilities, either they give an API in a common programming language, which is freely distributed and is easily implementable in our codebase. Or someone else than the service provider has created an open source API. You should be able to see some examples on github or sourceforge. Some service providers want only their API to be used, some dont mind other tool accessing the cloud using OAuth, etc. The student is expected to go through both the options for a particular cloud storage, identify the solution which is best suitable for already existing kipi-plugins framework, i.e. C++ / Qt, and implement it over the summer for atleast two major cloud services Google Drive and Dropbox.
== Roadmap and Releases Plan including all GSoC-2013 works ==
* '''Bugzilla entries:''' [https://bugs.kde.org/show_bug.cgi?id=300445 300445]
* '''Dependencies:''' APIs from G+, Dropbox, Skydrive tool
* '''Knowledge Prerequisite:''' C/C++, Qt
* '''Expected results:''' new tool to import/export items to Cloud web service
* '''Difficulty:''' easy / medium
* '''Lead Mentor:''' Smit Mehta  <smit dot meh at gmail dot com>

== Port Showfoto thumb-bar to Qt model/view ==


* '''Brief explanation:'''  ThumbBarView is a Qt3Support class based on Q3ScrollView class which will disappear with next Qt5. This class still only used by Showfoto editor. It must be ported to Qt model/view implementation using already existing common classes used in digiKam core.

== Port image editor Canvas classes to Qt model/view ==
== Coding Sprint ==


* '''Brief explanation:''' Image Editor canvas classes are Qt3Support classes based on Q3ScrollView which will disappear with next Qt5. This class is used by digiKam Image editor to render lead editor canvas and some tools canvas as ColorCorrection, CurvesAdjust, LevelAdjust, etc. It must be ported to Qt4 model/view implementation using already existing common classes used in digiKam core.
As lots of students come from India this year, it will be nice to plan a reunion between developers in this country to reduce travel and hotel costs.

Small Projects to Introduce Students

libjpeg-turbo detection

Auto-Lens correction tool don't work in BQM

Keyboard Tagging Improvements

  • Patch to review : http://git.reviewboard.kde.org/r/108382/
  • Assigned to : Saurabh Patel
  • Note : author keyboard workflow need to be understood and tested. It miss some menu entries to make shortcuts visible to end users.
  • Status : Pending

Panorama Tool - Hiding binaries details

  • Brief explanation : The goal is to hide the external binaries table when all the binaries are found on the system. A "Binaries' Details" button should be added, which upon clicked will show the table. If all the binaries are not found on start-up, then, the table should be shown by default (can be done by simply generating a pseudo click on the above described button once its implemented). Once it is successfully implemented here, it can be extended to all kipi-plugins which use external binaries.
  • Knowledge Prerequisite : C++, Qt

Fix KML export file generator

Remove internal Clapack library

Auto Crop Tool

  • Brief explanation: In some users case relevant of photo workflow, as Panorama assembly for example, digiKam need an algorithm to detect black hole borders of image and crop it automatically, respecting the most largest suitable image area. No adjustment must be require by end user. As JPEG is the most used image format used in photography and as JPEG library support a loss-less crop feature, a specific way must be implemented to process JPEG crop in batch without to lose image quality.
  • Dependencies: Batch Queue Manager, Image Editor.
  • Bugzilla entry: 267436, 204135

Students and mentors will use digikam-soc-devel at kde dot org mailing-list to coordinate projects.

Repositories, Branching, and Dates

Developer Account

To be able to code and work on digiKam project, each student must ask for a developer account to KDE Git repository administrator. See this page for details about KDE developers rules.

For Exiv2 project, please contact your mentor to get write access on Subversion repository.

Coverity Analyzer Account

digiKam and Exiv2 have registred in Coverty Scan Program to report all source code dysfunctions. Code is parsed automatically through a cronned script each week end. Reports are forwarded to digikam-soc-devel_at_kde_dot_org mailing-list.

To be able to review and fix errors reported by Scan analyzer, all students must be registered in the relevant Coverity project :

KDE Repository

All students working on digiKam will play with KDE Git repository from Git master branch.

We have a digiKam Software Compilation Repository where you will be able to checkout all sub-repositories including all shared libraries managed by team. This not included Exiv2 which is hosted outside KDE.

Students must have configured KDE developer account and checkout all code from KDE repository using SSH method.

Instructions to checkout and compile code is given in this README file.

Branches Creation and Maintenance

During GSoC 2013 coding time, git/master will still the stable implementation receiving important fixes. Each students must create a dedicated development branch for each project (your branch name is defined in project list by "Working on" property). In charge for each students to sync it with git/master periodically. To do it, see below as example how to sync digiKam "MY_DEVEL_BRANCH" branch tracking "remotes/origin/development/MY_DEVEL_BRANCH" from KDE git repository:

$>git checkout master
$>git pull --rebase
$>git checkout -b MY_DEVEL_BRANCH remotes/origin/development/MY_DEVEL_BRANCH
  Branch MY_DEVEL_BRANCH set up to track remote branch development/MY_DEVEL_BRANCH from origin.
  Switched to a new branch 'MY_DEVEL_BRANCH'
$>git merge master
  Merge made by the 'recursive' strategy.
  ...
$>git push


The 2 first lines take a sure that your local master repository is up to date. The 3rd line create in local the "MY_DEVEL_BRANCH" development branch. Merge between master and MY_DEVEL_BRANCH branch is done with 4th line. Git can ask you to resolve conflicts here. When it's done, it will ask you a commit comment. Finally push your merge into remote KDE repository.

Note: If you have already created MY_DEVEL_BRANCH branch, just run "git checkout MY_DEVEL_BRANCH" as well instead git checkout -b MY_DEVEL_BRANCH remotes/origin/development/MY_DEVEL_BRANCH. This give this concatenated command line:

$>git checkout master; git pull --rebase; git checkout MY_DEVEL_BRANCH; git pull; git merge master
  ...
$>git push


For advanced rules, especially to create remote working branches in KDE git repository, please look on this tutorial from KDE TechBase.
