Version: (using KDE KDE 3.5.1) Installed from: Gentoo Packages OS: Linux Killer feature :-) Simple CA (chromatic aberrations) correction plugin for digikam. Technically it can be simple as http://www.profibing.de/lisp/ca-correction.scm -- split image into RGB, resize layers separatelly and mix them again. Just with simple preview and rulers to adjust level of resize and select optical center (in case image was cropped and center of image is not center of lens). It would be nice to have because most cheap cams and lenses have serious chromatic aberrations, especially cheap ultra-zoom cameras like my S2 IS. Thanks!
No need to create a new tool for that. This color corrections must be added to current Lens Distortion corrector Gilles Caulier
Yeah this is a real good idea to do, my russian fisheye also suffers of a bit CA at the corners.
See https://bugs.kde.org/show_bug.cgi?id=98651, it should be (as mentioned by Gilles in #1 above) all be doable with one tool using the planned Lens correction database http://lists.freedesktop.org/archives/create/2007-May/000743.html
SVN commit 797980 by cgilles: digiKam from trunk : LensCorrection image editor plugin : - Use right dialog to have fine editing Lens correction settings preview. - Fix slots and signals names to be speedly read source code. * Update preview with Lens type is changed. Adrian: - Now plugin is suitable as well and work properlly, but of course uncomplete. - Bugs 143864 and 125233 will be closed when chromatic aberrations corrections will be corrected by this plugin. - Still few camera model not supported properlly by LensFun. There is no message to gui to ping user about. - Sometime, LensFun device is null when a camera model is selected. Why? - We need to improve gui to have a manual correction: for ex, lens focal must be selectable somewhere, and certainly more settings as Apeture. We need to discut about. - I think than a visual preview of distorsion using a grid is a excelent guide to users (like LensDistorsion plugin do) CCMAIL: adrian@suse.de BUG: 98651 CCBUGS: 143864 CCBUGS: 125233 M +58 -61 imageeffect_lenscorrection.cpp M +2 -2 imageeffect_lenscorrection.h M +43 -41 klensfun.cpp M +12 -10 klensfun.h WebSVN link: http://websvn.kde.org/?view=rev&revision=797980
