Kwinqaku elilandelayo siza kujonga kwiDCRaw. Le yenye Isicelo esivulekileyo esisetyenziselwa ukufunda iifomati zemifanekiso eluhlaza (RAW, CR2, njl ...). Ifunda ngokusisiseko ezo ziveliswa ziikhamera zedijithali eziphezulu. I-DCRaw sisixhobo esilula ukufakela esinakho Guqula le mifanekiso iluhlaza ifomathi yePPM kunye neTIFF esemgangathweni. Le nkqubo ibhalwe nguDave Coffin ngolwimi lwe-ANSI C, ke ngoko liqonga leqonga kwindalo.
Le nkqubo yifayile ye- isixhobo somgca wokuyalela. Oku kuthatha uluhlu lweefayile ukuqhubekeka, ukongeza kwimifanekiso oyifunayo. Oku kwenza ukuba kube lula ukusebenzisa iDCRaw kwikhonsoli, kodwa kunzima ngakumbi ukuyisebenzisa kwiinkqubo zangaphandle. Le nkqubo sisiseko sezicelo ezikwinqanaba eliphezulu zokulungiswa kwemizobo, njengababukeli kunye nabaguquli, zombini zasimahla nezabanini.
Njengoko benditshilo, iDCRaw sisixhobo somgca wokuyalela ukuguqula imifanekiso eluhlaza kwifom ye-TIFF okanye ye-PPM. Kukwanjalo iyahambelana nenqwaba yeekhamera kwaye inika abasebenzisi iiparameter ezininzi ukufumana iziphumo ezinqwenelekayo.
Nje ukuba sifumane iziphumo ezonelisayo, Kuyacetyiswa ukuba kusetyenziswe iDCRaw ngefayile yebatch ukuququzelela ukuguqulwa kweefayile ezininzi.
Faka iDCRaw kwi-Ubuntu 17.04
Ukufaka iDCRaw ku-Ubuntu siza kubhenela kuyo iPPA yayo ehambelanayo. Ukwenza oku, sivula i-terminal (Ctrl + Alt + T) kwaye sibhale oku kulandelayo:
add-apt-repository ppa:dhor/myway
Nje ukuba indawo yokugcina yongezwe, sihlaziya uluhlu lwesoftware kwaye siqhubeke nofakelo sisebenzisa iskripthi esilandelayo:
sudo apt update && sudo apt install dcraw -y
Ukuba yonke into ihambe kakuhle ngexesha lofakelo, usetyenziso lweDCRaw luya kusebenza ngokuchanekileyo.
Qalisa ngeDCRAW
Ngalo mzekelo, kunye Amaxwebhu asishiywayo ngumbhali kule nkqubo, abasebenzisi banokudlala ngezi ndlela kwaye benze ezethu iincwadi zeempendulo. Esi sisiqalo nje, amathuba ale nkqubo aphantse angapheli.
Ukwazi ngakumbi malunga neenketho ezikhoyo kule nkqubo, sinokwenza lo myalelo ulandelayo kwisiphelo sendlela kunye noluhlu lwe Iinketho ezikhoyo izakuvela ngezantsi:
dcraw
Eyona ndlela yokuqonda ukuba isebenza njani le nkqubo kukujonga umzekelo osebenzayo kunye nokukhupha ukhetho olusetyenzisiweyo kuyo. Umzekelo uya kuba ngulo unokubonwa kwiscreen esidlulileyo.
dcraw -v -w -H 1 -o 0 -q 3 -4 -T 1334012583_-mg-9952.CR2
Izinketho ezisetyenzisiweyo
- -v: Ngale ndlela, DCRAW iyakusibonisa ilog eveliswayo kwiscreen kuyo yonke inkqubo yophuhliso.
- -w: ukulinganisela okumhlophe kwekhamera. Ukuba sisebenzise -a endaweni yoko, sinokunyanzela i-DCRAW ukuba iqikelele ibhalansi emhlophe. Oku kuya kusekelwa kwisampulu eyenziweyo kumfanekiso wonke. Ingayinto efana nekhamera ezenzekelayo yeWB.
- -H 1: Olu phawu luncedo lusetyenziselwa Chaza unyango oluza kunikwa yiDCRAW kwimiqadi ephezulu. Siza kuba nakho ukuguqula iindawo ezitshisiweyo zibe zingwevu ezingathathi hlangothi (2), okanye sisebenzise umgca wokudibanisa ukubuyisa ezo zibane zitshileyo (0). Ukhetho 1 yeyona ndihlala ndiyibeka xa ndifuna ukuguqula ibhalansi emhlophe yoqobo kwaye ifoto ibonakaliswe. Iqinisekisa ukuba xa silungisa ibhalansi emhlophe, asihambisi i-histogram yalo naliphi na ijelo kwindawo yeepixels ezitshisiweyo.
- -o: olu khetho lubaluleke kakhulu ukuseta umbala wefayile yemveliso. Kule meko, ngexabiso 0 sixelela ukuba lingenzi naluphi na ulawulo lwemibala kwaye ligcine indawo yefoto yoqobo. Kodwa singaguqulela kwi-sRGB, iAdobeRGB, iProPhoto ...
- -q [0-3]: ngolu khetho siza kubonisa i-algorithm yokuguqulelwa kwe-matrix. Ngokwesiqhelo, Ixabiso 3 (AHD) lisebenza kakuhle kuba yi-algorithm eguqukayo, nangona kunokwenzeka ukuba kwiimodeli ezithile zekhamera kufuneka uzame ezinye kwaye uzigcine kwiifoto zakho.
- -4: ukuba asilubeki olu khetho, umfanekiso onesiphumo uya kuba nemibala engama-8 ngombala kwisitishi ngasinye. A) Ewe Siqinisekisa imifanekiso eli-16.
- -T: ukuvelisa ifayile yeTIFF. Kungcono ukuba kamva siza kusebenza umfanekiso kwinkqubo yokubuyisela kwakhona.
Khipha iDCRAW
Ukuphelisa le nkqubo kwinkqubo yethu yokusebenza, kuya kufuneka silandele amanyathelo aqhelekileyo. Kuqala cima indawo yokugcina ngokuchwetheza kwi-terminal (Ctrl + Alt + T) lo myalelo ulandelayo:
add-apt-repository -r ppa:dhor/myway
Ngoku sinokucima inkqubo. Kwisiphelo esinye sibhala:
sudo apt remove dcraw
Ukuba uncedo lwenkqubo kunye nomzekelo okweli nqaku akonelanga, nabani na onokulufuna unokusebenzisa oku kulandelayo tutorial malunga neDCRAW (ngeSpanish).
