Feature Wishes for Oyranos
The assignment of items to a person does not mean there happens currently work. So offering help is better than waiting with a item of interest.
A closely related source for project ideas is the Google Summer of Code wiki page of OpenICC.
- (done as pddt) implement Device_Settings in ICC profiles
- changed to ICC meta tag of type dict in v0.1.13
Progress: 100% [done] | Target: 0.1.10 | Start: 2008.00.00 | Assigned to: Kai-Uwe Behrmann |
- generalise to Sane, CUPS ... see as well here
Progress: 100% [done] | Target: 0.1.10 | Start: 2009.03.00 | Assigned to: Kai-Uwe Behrmann, Yiannis Belias |
- (done) publicise the device module communication protocol on a separate ColourWiki page
- (done) integrate into the KDE Kolor-manager mentored by OpenICC developers
Progress: 100% [done] | Target: 0.1.10 | Start: 2008.03.00 | Assigned to: Joe Simon, Hal V. Engel, Cyrille Berger, Kai-Uwe Behrmann |
- check for validity of a display setup (calibrated: yes/no, expired, ...)
- done (add non EDID monitor support - by a mix of X description and by Xinerama geometry (prepared for 0.1.8))
Progress: 100% [done] | Target: 0.1.8 | Start: 2007.08.00 | Assigned to: Kai-Uwe Behrmann |
- done (common screen naming scheme for X11, osX and Windows)
- Named Colours in X11, osX ,Windows representation
- (done) clear about VCGT handling, use Xcalib (licensing?) or ArgyllCMS, give at least a hint at configure time "found Xcalib/Argyll - can load VCGT" - Oyranos shells out for xcalib
- (done) support the upcoming X11 CM protocols developed by Tomas Carnecky. implemented in graph but need drafting/specification
- done (XRandR support)
- (done) support Apples X11
- check for well behaving of Editing colour spaces (Matrix, RGB: gamma equally over all channels, Gray axis, ...)
- (done) check ICC profiles It is something better suited for SampleICC - packaged on OBS.
- (obsolete) extraction of colorimetric informations from a profile like primaries, gamma or profile type
- use of standard folders for: display profiles, RGB editing profiles, CMYK editing profiles.
- color management policies
Progress 90% | Version: 0.1.x | Start: 2004 | Assigned to: Kai-Uwe Behrmann |
- done (only allow flat color documents or allow mixed mode documents ?)
- done (how to deal with profile mismatches during opening files ?)
- done (how to deal with profile mismatches during placing content ?)
- to add:
- done (add CMYK editing profile (OY_DEFAULT_EDITING_CMYK_PROFILE))
- done (add non-editable web colour space sRGB for displaying - should be used during download from web (OY_DEFAULT_WEB_PROFILE=sRGB))
- done (profile assigning for untagged data during opening (auto / leave / ask) (OY_UNTAGGED_ASSIGN_ACTION))
- done (add RGB/CMYK opening mismatch policy (convert / leave attached profile/pop-up) , in an pure sRGB environment it could be used to make all unknown RGB content equal (OY_MISMATCH_RGB_OPEN_ACTION ...))
- done (profile assigning for mismatched data during editing policy, harmonise during editing for homogeneous colour space documents (OY_MISMATCH_CMYK_CHANGE_ACTION ...))
- note: placing and editing files could equal react regarding mismatch (handles the mismatch question from above)
- (done) mixed colour space documents for internet warning/quiet (OY_MIXED_COLOUR_INTERNET_DOCUMENT_WARNING)
- rendering intent (Craig Ringer's suggestion)
- Perceptual
- Relative Colorimetric with BPC
- -- Rarely Needed --
- Relative Colorimetric without BPC
- Absolute Colorimetric
- Saturation
- BPC affect all RIs; a Relative Colorimetric with BPC can only be used for convenience
- implement like a skin?
- Where to translate the general CMS options into the above suggested combined options? In the 'oicc' module?
- Reference: AdobeBPC spec
- allow non persistent settings, examples:
- (done) useful for temporarily adding profile paths in osX bundles - paths follow the OpenICC spec through XDG_DATA_DIRS
- switching default profiles to gamma 1.0 versions in one application, without touching other applications
Progress: 100% | Version: x.x.x | Start: defacto 2004 | Assigned to: open |
- (obsoleted by XDG variables) ICC_PROFILE_PATH ? how to interact with Oyranos
- (done) update Oyranos' internal path representation to the OpenICC Directory Proposal
- (done) OY_MODULE_PATHS for CMM's
- (done) update to v0.2
- (done) naming of ECI profiles to something FOGRA corresponding (Chris Murphy and others on OpenICC)
- (done) most ECI profiles are replaced with Argyll created ones
- (done) remains to relicense or replace the eciRGB ones
- country specific settings
Progress: 92% | Version: 0.1.8 | Start: | Assigned to: Kai-Uwe Behrmann |
- back end API a typical CMM should provide
- on disk caching
- (done) transform caching (file format - device link)
Progress: 75% | Version: x.x.x | Start: 2007 | Assigned to: Kai-Uwe Behrmann (Scribus?) |
- front end API, transforms, caching, image description - buffer layout / screen position
Progress: 80% | Version: 1.x.x | Start: 2007 | Assigned to: Kai-Uwe Behrmann |
- Oyranos/Null Transform Checking - implicite; beside explicite opt out support in options
Progress: 0% | Version: 1.x.x | Start: 2008 | Assigned to: ? |
- options handling (xml, GUI)
- (done) static options should be displayed to users according to preferences (for instance mismatch option)
- options handling (xml, GUI)
Progress: 100% | Version: x.x.x | Start: 2006 | Assigned to: Kai-Uwe Behrmann + ? |
Progress: 20% | Version: 1.x.x | Start: 2008 | Assigned to: Marijana Novakovic |
- file support (tiff,png,jpeg)
Progress: 35% | Version: first use in Colori | Start: 2007-09-10 | Assigned to: Kai-Uwe Behrmann |
- colour information structure
Progress: 60% | Version: first use in ICC Examin v0.45 | Start: 2007-09-03 | Assigned to: Kai-Uwe Behrmann |
Constitute a colour patch representation:
- done - CIELab representation
- done - arbitrary channels (32)
- done - channel characterisation (4 byte ICC signature)
- done - channel names list
- done - colour name
- done - colour description
- done - colour nick name
- done - colour reference (ICC profile)
- done - cgats representation, this can contain additional observer characteristics or spectral data
- state is shown here
- done - allow for grouping ( swatches )
- exchange as colour selection(s) in X11, Quartz ...
- Named Colours (oyNamedColour(s)_s) <-> data blob (Create's colour swatch XML, CGATS, ...) in a plugable fashion
- keep in sync with Create
- HDR range information
- creator signature?
- gamut warning with the device, which is exceeded - monitor, printer, colour space
- to sRGB float conversion from Lab(D50)/XYZ or from channels over ICC profile with lcms2
- gamma handling?
- extra channel handling (scheme for explicitly naming alpha, UV ...) enums? string tags? ...
- done (split Oyranos headers for users, configuration)
- done (show in headers only stable functions)
- done (remove unstable functions from descriptions)
- (done) later show only advanced options to those users who like it
- something like default settings / policy
- and modify policy, advanced or custom
- done(v0.1.5) Bob Friesenhahn suggested Oyranos should be completely relocatable
- (done) IPC (Xorg, ...?)
Oyranos Roadmap
- stable API
- graph API - work in progress
- add script host (OpenGTL/OpenCL/...)
- write new renderer for oForms (Qt/Gtk/...)
- stable API
- settings, profile query - seems a good candidate (oyranos.h + oyranos_icc.h)
- device and profile APIs - with the help of the GSoC2010 code refactoring
- (done) embed Elektra for easier distribution
- (done) patch SANE
- (done) add SANE module
- clarify image_display example (FLTK CM policy on osX/native X/...)
- (done) install compiz plug-in (split out like ICC Examin?)
- (done) install Xorg tools
- (done) work with 'meta' tag
- (done) embed meta tag - in device specific tools like oyranos-monitor
- use intermediate XML to allow for easy editing let specialised tools care about, like SampleICC, or...
- (done) couple close to the according driver, e.g. oyX1, oyRE ...
- (done) split out icc-profiles - http://sourceforge.net/projects/openicc/files/OpenICC-Profiles/
- (done) finish lcms2 CMM https://sourceforge.net/tracker/?func=detail&aid=3054285&group_id=177017&atid=879553
- (done)missed monitor API in doxygen documentation
- (done)_ICC_PROFILE_IN_X_VERSION lost?
- (done) device DB framework
- (done) error handling
- (done) information callback function:
int (*callback)(int code, const char* format, ...)
- internally all can stay with macros
- the context should remain distinguishable, as over a pointer or a ID, the anonymous callback design above is problematic for OO programming
- override default settings, dependent whether they are inbuild or explicitely set by a user http://www.behrmann.name/wind/cinepaint/cinepaint_2007.04.13_1.html: delayed until options are inside a oyOptions_s objetc
- (done) gray profile setting
- (done) license change as stated
- (done) new default profiles from ECI
- (done) investigate in ColorSync ignoring some CMM:SGI marked profiles
- (done) look into newer Elektra library API (Oyranos v0.1.7 can use Elektra v0.6.4) v0.1.8 uses Elektra v0.7.x(which waits for its release)
