Muchikamu chinotevera tichaenda kutarisa DCRaw. Ichi ndicho chimwe open source application yakashandiswa kuverenga akawanda mafomati emifananidzo (RAW, CR2, nezvimwe ...). Iyo inoverenga izvo zvinowanzo gadzirwa neepamusoro-magumo edhijitari kamera. DCRaw chishandiso chakareruka chekuisa nacho zvatinogona chinja iyi mifanikiso yakasvibirira kuita yakajairwa PPM uye TIFF mafomati emifananidzo. Chirongwa ichi chakanyorwa naDave Coffin mune ANSI C mutauro, saka iri muchinjiko-chikuva mune zvakasikwa.
Ichi chirongwa i raira mutsara chishandiso. Izvi zvinotora rondedzero yemafaira kuti iitwe, kuwedzera pane izvo zvinodiwa zvemifananidzo. Izvi zvinoita kuti DCRaw ive nyore kushandisa kubva kunyowani, asi zvakanyanya kunetsa kushandisa kubva kunze zvirongwa Iyi purogiramu ndiyo hwaro hweakasiyana-siyana epamusoro-chikamu graphic ekugadzirisa kunyorera, sevataridzi uye vashanduri, vese vakasununguka uye vane kodzero.
Sezvandinotaura, DCRaw chirairo mutsara chishandiso chekushandura mifananidzo mbishi kune TIFF kana PPM fomati. Izvo zvakare inowirirana nemazana emakamera uye inopa vashandisi akawanda ma parameter kuti vawane mhedzisiro yaunoda.
Kana tangowana mhedzisiro inogutsa, zvinokurudzirwa kushandisa DCRaw kuburikidza nebatch faira kufambisa kuwanda kutendeuka kwemafaira akawanda.
Isa DCRaw pane Ubuntu 17.04
Kuisa DCRaw muUbuntu tiri kuenda ku inoenderana PPA. Kuti tiite izvi, isu tinovhura terminal (Ctrl + Alt + T) uye tinyore zvinotevera mairi:

Nemuenzaniso uyu, uye zvinyorwa izvo munyori anotisiira isu muchirongwa, vashandisi vanogona kutamba nesarudzo idzi uye kugadzira zvinyorwa zvedu. Uku kungori kutanga, mikana yechirongwa ichi inenge isingagumi.
Kuti uzive zvakawanda nezve sarudzo dziripo muchirongwa ichi, tinogona kuteedzera unotevera kuraira mune terminal uye runyorwa rwe Zviripo zviripo ichaonekwa pazasi:

Sarudzo dzakashandiswa
- -v: nechisarudzo ichi, DCRAW ichatiratidza iro danda riri kugadzirwa pachiratidziri panguva yese yekusimudzira.
- -w: kamera chena chiyero. Kana isu tikashandisa -a pachinzvimbo, taigona kumanikidza DCRAW kuti ifungidzire chena chiyero. Izvi zvichave zvinoenderana nesampling inoitwa yemufananidzo wese. Chingave chinhu senge otomatiki kamera WB.
- -H 1: Unhu hunobatsira hunoshandiswa tsanangura mabatirwo achaitwa neDCRAW kumatanda akakwirira. Tichakwanisa kushandura nzvimbo dzakatsva kuita neutral grey (2), kana kushandisa mutsetse kuturikidzana kudzora iwo akapiswa mwenje (0). Sarudzo 1 ndiyo yandinowanzoisa pandinenge ndichida kugadzirisa chiyero chepachena chichena uye zvakare mufananidzo wacho wakanyatsoburitswa. Izvo zvinoona kuti kana tichigadzirisa chena chiyero, isu hatifambise iyo histogram yechero chiteshi kune iyo nzvimbo yekutsva mapikisheni.
- -o: iyi sarudzo yakanyanya kukosha kumisikidza iyo color chimiro yeinobuditsa faira. Mune ino kesi, ine kukosha 0 tinoiudza kuti irege kuita chero chengetedzo yemavara uye kuchengetedza nzvimbo yemufananidzo wekutanga. Asi isu taigona kushandura kuita sRGB, AdobeRGB, ProPhoto ...
- -q [0-3]: nesarudzo iyi tichaenda kuratidza iyo matrix yekushandura algorithm. Kazhinji, kukosha 3 (AHD) inoshanda zvakanyanya sezvo iri algorithm inochinja, kunyangwe zvichikwanisika kuti mune mamwe mamamera kamera unofanirwa kuyedza vamwe nekuachengeta ako mafoto.
- -4: kana isu tikasaisa iyi sarudzo, iyo inoguma mufananidzo unove uine masere masere eruvara pane chiteshi. A) Hongu isu tinoona 16-bit mifananidzo.
- -T: gadzira iyo TIFF faira. Iyo yakanakisa kana gare gare tichizoshanda mufananidzo mune retouching chirongwa.
Uninstall DCRAW
Kuti tibvise chirongwa ichi kubva kune yedu yekushandisa system, isu tinongofanirwa kutevedzera akajairwa matanho. Kutanga bvisa iro repo nekutaipa mune iyo terminal (Ctrl + Alt + T) unotevera kuraira:
