Kutulutsidwa kwa pulogalamu yokonzekera ndi kukonza zithunzi za digito Darktable 4.2 kwaperekedwa, komwe kumayenderana ndi chaka chakhumi cha kukhazikitsidwa koyamba kwa polojekitiyi. Darktable imagwira ntchito ngati njira yaulere ya Adobe Lightroom ndipo imagwira ntchito yosawononga yokhala ndi zithunzi zosaphika. Darktable imapereka ma module ambiri opangira mitundu yonse ya ntchito zosinthira zithunzi, imakupatsani mwayi wokhala ndi database yazithunzi zomwe zimachokera, kuyang'ana zithunzi zomwe zilipo kale ndipo, ngati kuli kofunikira, gwiritsani ntchito kukonza zolakwika ndikuwongolera mawonekedwe, ndikusunga chithunzi choyambirira. ndi mbiri yonse ya ntchito ndi izo. Khodi ya polojekitiyi imalembedwa mu C ndipo imagawidwa pansi pa layisensi ya GPLv3. Mawonekedwewa amapangidwa pogwiritsa ntchito laibulale ya GTK. Misonkhano yama Binary imakonzekera Linux (OBS, flatpak), Windows ndi macOS.
Zosintha zazikulu:
- Pulogalamu yatsopano yosinthira ya Sigmoid ikufunsidwa, yomwe imaphatikiza magwiridwe antchito a filimu ndi ma curve modules, ndipo angagwiritsidwe ntchito m'malo mwake kuti asinthe kusiyana kapena kukulitsa mawonekedwe osinthika a zochitika kuti agwirizane ndi mawonekedwe azithunzi.
- Ma algorithms awiri atsopano obwezeretsa mitundu ya ma pixel omwe alibe chidziwitso chokhudza mayendedwe a RGB (ma pixel omwe ali m'malo owunikiridwa a chithunzi, magawo amtundu omwe sensor ya kamera siingathe kudziwa) awonjezedwa pagawo lokulitsanso: "mitundu yosiyana" ndi " pa segmentation."
- Pixelpipe yomwe imagwiritsidwa ntchito powonetsera mumayendedwe (darkroom) yakonzedwanso. Mapaipi omwe atchulidwa tsopano atha kugwiritsidwanso ntchito pazenera lachiwiri lazenera, mu manejala wobwereza, pawindo lowoneratu kalembedwe, ndi ntchito zogwirira ntchito ndi zithunzi.
- Zenera lachiwiri lopangira zithunzi (chipinda chamdima) tsopano limathandizira kuyang'ana koyang'ana ndi mitundu ya ISO-12646 yamitundu.
- Gawo lachidule lakonzedwanso kwathunthu ndipo m'malo mogwira madera okhazikika pazenera, limagwiritsa ntchito mawonekedwe osinthika azithunzi pogwiritsa ntchito payipi ya pixel, kulola kusuntha ndi kusuntha pogwiritsa ntchito kiyibodi kapena mbewa.
- Woyang'anira wobwereza adawongoleredwa, zomwe zasamutsidwa kumapaipi ang'onoang'ono powerengera madera kuti awonedwe, zomwe zidapangitsa kuti zitheke kupeza tizithunzi zofanana ndi chithunzicho pokonza.
- Ndizotheka kuwoneratu zotsatira za kugwiritsa ntchito kalembedwe kachifaniziro, pa siteji isanachitike kugwiritsa ntchito kwenikweni (pamene mukweza mbewa pamwamba pa zomwe zili mu menyu kapena mndandanda, chida chokhala ndi chithunzithunzi cha zotsatira za kugwiritsa ntchito kumawonetsedwa).
- Ma module owongolera ma lens amasinthidwa kuti aganizire zowongolera ma lens zolembedwa mu block ya EXIF .
- Thandizo lowonjezera powerenga ndi kulemba zithunzi za JPEG XL
- Thandizo lowonjezera la mafayilo okhala ndi JFIF (JPEG File Interchange Format) yowonjezera.
- Thandizo lambiri lamitundu ya AVIF ndi EXR.
- Thandizo lowonjezera pakuwerenga zithunzi mumtundu wa WebP. Mukatumiza ku WebP, kuthekera koyika mbiri ya ICC kwakhazikitsidwa.
- Ma module othandizira ndi kukonza asinthidwa kuti mawonekedwe awo awonekere nthawi yomweyo akakulitsidwa (popanda kufunikira kopukutira).
- Anawonjezera mawonekedwe atsopano omwe amagwiritsidwa ntchito pokulitsa ndi kugwa ma module.
- Kusungirako pakugwira ntchito kwa mapaipi a pixel (pixelpipe) adakonzedwanso, kugwira ntchito kwa cache kwawonjezeka.
- Mawonekedwe a masilayidi akonzedwanso, momwemo chithunzithunzi chosavuta chimawonetsedwa chithunzi chonse chisanasinthidwe.
- Mndandanda watsopano wotsikira pansi wawonjezedwa kugawo lakumanzere, momwe mungathe kuwonjezera ndi kuchotsa zosefera.
- Mawonekedwe a fyuluta yoyezera siyana akonzedwanso.
- Anawonjezera kuthekera kosintha mawonekedwe osagwiritsa ntchito gudumu la mbewa, mwachitsanzo pama PC a piritsi.
- Njira yolumikizira matayilo pakati pa OpenCL ndi CPU ikukonzedwa, yomwe imakulolani kuti muphatikizepo ma CPU m'magawo pamene khadi yojambula ilibe kukumbukira kokwanira kuti mugwiritse ntchito OpenCL.
