Qhov kev tso tawm ntawm qhov kev pab cuam rau kev teeb tsa thiab ua cov duab digital Darktable 4.2 tau nthuav tawm, uas tau mob siab rau hnub thib kaum ntawm kev tsim thawj qhov kev tso tawm ntawm qhov project. Darktable ua raws li lwm txoj hauv kev pub dawb rau Adobe Lightroom thiab tshwj xeeb hauv kev ua haujlwm tsis muaj kev puas tsuaj nrog cov duab nyoos. Darktable muab kev xaiv loj ntawm cov qauv rau kev ua txhua yam kev ua haujlwm ntawm kev yees duab, tso cai rau koj khaws cov ntaub ntawv ntawm cov duab los ntawm cov duab, pom cov duab los ntawm cov duab uas twb muaj lawm thiab, yog tias tsim nyog, ua haujlwm los kho qhov cuam tshuam thiab txhim kho kom zoo, thaum khaws cov duab qub. thiab tag nrho cov keeb kwm ntawm kev ua haujlwm nrog nws. Txoj haujlwm code yog sau rau hauv C thiab muab faib raws li GPLv3 daim ntawv tso cai. Lub interface yog tsim siv lub tsev qiv ntawv GTK. Binary sib dhos yog npaj rau Linux (OBS, flatpak), Windows thiab macOS.
Cov kev hloov loj:
- Ib qho tshiab Sigmoid transformation module yog npaj siab, uas sib txuas cov kev ua haujlwm ntawm cov yeeb yaj kiab thiab lub hauv paus nkhaus modules, thiab tuaj yeem siv hloov pauv qhov sib txawv lossis nthuav dav qhov sib txawv ntawm qhov xwm txheej kom phim qhov ntau yam ntawm lub vijtsam.
- Ob lub algorithms tshiab rau kev kho cov xim ntawm pixels uas tsis muaj cov ntaub ntawv hais txog RGB raws (pixels hauv thaj chaw pom ntawm daim duab, cov xim tsis pom kev uas lub koob yees duab sensor tsis tuaj yeem txiav txim siab) tau ntxiv rau qhov tseem ceeb ntawm kev tsim kho: "tawm xim" thiab "raws li ntawm segmentation."
- Lub pixelpipe siv los tso saib hauv hom kev ua haujlwm (darkroom) tau rov ua haujlwm dua. Cov raj xa dej tau teev tseg tam sim no kuj tseem tuaj yeem siv rau hauv lub qhov rai thib ob ntawm qhov screen, nyob rau hauv tus thawj tswj duplicate, hauv qhov style saib ua ntej qhov rais, thiab hauv kev ua haujlwm rau kev ua haujlwm nrog snapshots.
- Qhov thib ob duab ua qhov rais (darkroom) tam sim no txhawb kev tsom xam thiab ISO-12646 xim rating hom.
- Lub snapshot module tau raug kho dua tshiab thiab es tsis txhob ntes cov chaw ruaj khov ntawm lub vijtsam, nws siv cov duab dynamic tsim siv pixel pipeline, tso cai rau zooming thiab panning siv cov keyboard lossis nas.
- Tus thawj tswj duplicate tau raug txhim kho, uas tau hloov mus rau cov kav dej tshiab subroutines thaum xam cov cheeb tsam rau kev saib ua ntej, uas ua rau nws muaj peev xwm tau txais cov duab me me zoo ib yam rau cov duab hauv kev ua haujlwm.
- Nws tuaj yeem saib ua ntej cov txiaj ntsig ntawm kev siv tus qauv kev cai rau cov duab, ntawm theem ua ntej daim ntawv thov tiag tiag ntawm cov nyhuv (thaum koj txav tus nas hla cov nyhuv hauv cov ntawv qhia zaub mov lossis daim ntawv teev npe, cov lus qhia nrog tus ntiv tes xoo ntawm cov txiaj ntsig ntawm siv cov nyhuv tshwm sim).
- Lub lens distortion kho module yog yoog mus rau hauv tus account lens kho cov ntaub ntawv sau tseg hauv EXIF ββββ thaiv.
- Ntxiv kev txhawb nqa rau kev nyeem ntawv thiab sau cov duab JPEG XL
- Ntxiv kev txhawb nqa rau cov ntaub ntawv nrog JFIF (JPEG File Interchange Format) txuas ntxiv.
- Txhim kho profile txhawb rau AVIF thiab EXR hom.
- Ntxiv kev txhawb nqa rau kev nyeem cov duab hauv WebP hom. Thaum xa tawm mus rau WebP, lub peev xwm los teeb tsa ICC profiles tau ua tiav.
- Pab thiab ua modules tau hloov pauv kom lawv cov interface tam sim ntawd pom nyob rau hauv tag nrho thaum nthuav (tsis tas yuav scroll).
- Ntxiv cov nyhuv animated tshiab uas yog siv thaum nthuav thiab tawg modules.
- Caching thaum lub sijhawm ua haujlwm ntawm pixel pipelines (pixelpipe) tau raug kho dua tshiab, cache efficiency tau nce.
- Cov slideshow hom tau raug redesigned, nyob rau hauv uas ib tug yooj yim thumbnail yog qhia ua ntej tag nrho cov duab ua tiav.
- Cov ntawv qhia zaub mov nco-down tshiab tau ntxiv rau sab laug lim vaj huam sib luag, uas koj tuaj yeem ntxiv thiab tshem tawm cov lim.
- Lub interface ntawm qhov ntsuas qhov ntsuas ntau tau raug kho dua tshiab.
- Ntxiv lub peev xwm los tswj cov duab tsis siv lub log nas, piv txwv li ntawm cov ntsiav tshuaj PCs.
- Ib hom tiling sib npaug ntawm OpenCL thiab CPU tau thov, uas tso cai rau koj los koom nrog CPU hauv segmentation thaum daim npav daim npav tsis muaj lub cim xeeb txaus los ua qhov haujlwm no siv OpenCL.
