Ukukhishwa kohlelo lokucutshungulwa kwezithombe okuphrofeshinali I-Darktable 4.2

Ukukhishwa kohlelo lokuhlela nokucubungula izithombe zedijithali i-Darktable 4.2 yethulwe, ebekwe isikhathi ukuze ihambisane nokugubha iminyaka eyishumi kwasungulwa ukukhishwa kokuqala kwephrojekthi. I-Darktable isebenza njengenye yamahhala ye-Adobe Lightroom futhi igxile emsebenzini ongacekeli phansi onezithombe ezingavuthiwe. I-Darktable inikeza ukukhethwa okukhulu kwamamojula okwenza zonke izinhlobo zemisebenzi yokucubungula izithombe, ikuvumela ukuthi ugcine isizindalwazi sezithombe zomthombo, uhlole ngokubuka izithombe ezikhona futhi, uma kunesidingo, wenze imisebenzi yokulungisa ukuhlanekezela nokuthuthukisa ikhwalithi, kuyilapho ulondoloza isithombe sokuqala. kanye nawo wonke umlando wokusebenza nayo. Ikhodi yephrojekthi ibhalwe ngo-C futhi isatshalaliswa ngaphansi kwelayisensi ye-GPLv3. Isixhumi esibonakalayo sakhiwe kusetshenziswa umtapo wezincwadi we-GTK. Imihlangano kanambambili ilungiselelwa i-Linux (OBS, flatpak), iWindows kanye ne-macOS.

Izinguquko eziyinhloko:

• Kuhlongozwa imojuli entsha yokuguqulwa kwe-Sigmoid, ehlanganisa ukusebenza kwamamojula wefilimu nejika lesisekelo, futhi ingasetshenziswa esikhundleni sokushintsha ukugqama noma ukwandisa ububanzi obuguquguqukayo besigcawu ukuze ifane nobubanzi obuguquguqukayo besikrini.
• Ama-algorithms amabili amasha okubuyisela imibala yamaphikseli antula ulwazi mayelana namashaneli e-RGB (amaphikiseli asezindaweni ezikhanyisiwe zesithombe, amapharamitha wombala lapho inzwa yekhamera engakwazi ukunquma) angeziwe kumojula yokwakhiwa kabusha okugqanyisiwe: “umbala ophikisanayo” kanye “ nesisekelo ekuhlukaniseni."
• I-pixelpipe esetshenziselwa ukubonisa kumodi yokucubungula (i-darkroom) isisetshenzwe kabusha. Ipayipi elishiwo manje lingasetshenziswa ewindini lesikrini sesibili, kusiphathi esiyimpinda, ewindini lokubuka kuqala lesitayela, kanye nemisebenzi yokusebenza ngezifinyezo.
• Iwindi lesibili lokucubungula isithombe (igumbi elimnyama) manje lisekela ukutholwa kokugxila kanye nezindlela zokulinganisa imibala ze-ISO-12646.
• Imojula yesifinyezo iklanywe kabusha ngokuphelele futhi esikhundleni sokuthwebula izindawo ezigxilile zesikrini, isebenzisa ukukhiqizwa kwesithombe esiguqukayo kusetshenziswa ipayipi lamaphikseli, okuvumela ukusondeza nokunwebeka kusetshenziswa ikhibhodi noma igundane.
• Umphathi oyimpinda uthuthukisiwe, oye wadluliselwa kumapayipi amancane angaphansi lapho kubalwa izindawo ukuze zihlolwe kuqala, okwenze kwaba nokwenzeka ukuthola izithonjana ezifana nesithombe kumodi yokucubungula.
• Kungenzeka ukuhlola kuqala umthelela wokusebenzisa isitayela sangokwezifiso esithombeni, esigabeni ngaphambi kokusetshenziswa kwangempela komphumela (uma uhambisa igundane phezu komphumela okwimenyu noma ohlwini, ithiphu yamathuluzi enesithonjana somphumela ukusebenzisa umphumela kuyaboniswa).
• Imojula yokulungiswa kokuhlanekezelwa kwamalensi ishintshwa ukuze icabangele idatha yokulungiswa kwelensi eqoshwe kubhulokhi ye-EXIF ​​.
• Ukwesekwa okwengeziwe kokufunda nokubhala izithombe ze-JPEG XL
• Ukwesekwa okwengeziwe kwamafayela anesandiso se-JFIF (JPEG File Interchange Format).
• Ukusekelwa kwephrofayela okuthuthukisiwe kwamafomethi e-AVIF ne-EXR.
• Ukwesekwa okwengeziwe kokufunda izithombe ngefomethi ye-WebP. Lapho uthekelisa ku-WebP, amandla okushumeka amaphrofayela e-ICC asetshenzisiwe.
• Amamojula omsizi nawokucubungula ashintshiwe ukuze isixhumi esibonakalayo sibonakale ngokugcwele lapho sandiswa (ngaphandle kwesidingo sokuskrola).
• Kwengezwe umphumela omusha wokugqwayiza osetshenziswa lapho kunwetshwa futhi kugoqwa amamojula.
• Ukugcinwa kunqolobane ngesikhathi sokusebenza kwamapayipi amaphikseli (pixelpipe) kuklanywe kabusha ngokuphelele, ukusebenza kahle kwenqolobane kwenyukile.
• Imodi yombukiso wamaslayidi isiklanywe kabusha, lapho isithonjana esenziwe lula siboniswa ngaphambi kokuba isithombe esigcwele sicutshungulwe.
• Imenyu yokudonsela phansi entsha yengezwe kuphaneli yesihlungi esingakwesokunxele, ongakwazi ukwengeza nokukhipha izihlungi ngazo.
• Isixhumi esibonakalayo sesihlungi sesilinganiso sobubanzi siklanywe kabusha.
• Kwengezwe ikhono lokukhohlisa umumo ngaphandle kokusebenzisa isondo legundane, isibonelo kuma-tablet PC.
• Kuhlongoziwe ukulinganisa kwemodi yokuthayela phakathi kwe-OpenCL ne-CPU, okukuvumela ukuthi ubandakanye i-CPU ekuhlukaniseni lapho ikhadi lezithombe lingenayo inkumbulo eyanele yokwenza lo msebenzi usebenzisa i-OpenCL.
