Kanema: Chida Chofufutira Sichikugwira Ntchito mu GIMP? Nayi Momwe Mungakonzere

Zomwe Chida Chofufutira Chimachita

Poyambira, chida chofufutira chimakulolani kufufuta ma pixel mu chithunzi chanu kapena mawonekedwe anu kuti akhale mtundu wakumbuyo kapena kuwonekera. Kaya ifufutika kumtundu wakumbuyo kapena kuwonekera zimatengera gawo lomwe mwasankha, komanso ngati gawolo lili ndi njira ya alpha.

Kuwonjezera Alpha Channel ku Layer

Magawo mu GIMP ali ndi njira zitatu zamitundu ndi njira ya alpha. Matchanelo amitundu ndi Ofiira, Obiriwira, ndi Buluu, ndipo mitunduyi imaphatikizidwa kuti ipange chomwe chimatchedwa Chithunzi Chophatikiza - kapena chithunzi chamitundu yonse chomwe mumachiwona pazenera. Komabe, zithunzi kapena nyimbo zina zilinso ndi njira yachinayi, yotchedwa Alpha channel, yomwe imayimira kuwonekera pansi pa chithunzi chamagulu. Mwa kuyankhula kwina, ngati mutachotsa ma pixel amtundu pachithunzi chanu, chithunzithunzi chowonekera kapena chowonekera chidzawonekera pomwe ma pixelwo adachotsedwa.

Chida Chofufutira Sichikugwira Ntchito GIMP 2 10

Kumbali ina, ngati mulibe njira ya alpha pazosanjikiza, GIMP imangogwiritsa ntchito chida chofufutira kupenta mtundu wakumbuyo womwe mwasankha pomwe mukuyesera "kufufuta" ma pixel (monga momwe zasonyezedwera pachithunzi pamwambapa - I. adalozera chida chofufutira chomwe chili mubokosi lazida ndi muvi wofiyira. Malo obiriwira omwe adapentidwa pachithunzipa ndi pomwe ndidayesa kugwiritsa ntchito chofufutira popanda njira ya alpha).

Onjezani Alpha Channel Kuti Chida Chofufutira chigwire ntchito

Chifukwa chake, kuti muwonjezere njira ya alpha kukusanjikiza, dinani kumanja pagawo lomwe lili mkati mwa gululo ndikupita ku "Add Alpha Channel" (yomwe ikuwonetsedwa ndi muvi wofiyira pachithunzi pamwambapa).

Onani Makanema Anu a Alpha Channel mu GIMP

Mutha kuwonanso kuti chithunzi chanu chili ndi njira ya alpha popita ku tabu ya "Channel" (muvi wofiyira) ndikuyang'ana njira yotchedwa "Alpha" pansi pamitundu itatu (muvi wobiriwira).

Chida chofufutira chokhala ndi Transparent Background GIMP

Ngati ndibwerera ku gulu langa la Layers ndipo tsopano ndijambule chofufutira pa chithunzi changa, ma pixel omwe ndidafafaniza tsopano akuwoneka ngati bolodi yotuwa m'malo mwa mtundu wanga wakumbuyo. Bokosi la imvi limayimira kuwonekera mu GIMP. Chifukwa chake, ngati ndidatumiza izi ngati fayilo yomwe imathandizira kuwonekera (monga fayilo ya .PNG), malo omwe gulu loyang'anira imvi lili pano likhoza kuwonedwa kwathunthu mu fayilo yomaliza.

Kufufuta Mukakhala Ndi Zigawo Zambiri

Chilichonse chomwe tawonetsa mpaka pano chikuphatikiza chopangidwa chomwe chinali ndi gawo limodzi lokha - chithunzithunzi - koma bwanji ngati zolemba zanu zili ndi zigawo zingapo?

GIMP 2 10 12 Pangani Gulu Latsopano

Mu GIMP, mutha kukhala ndi gawo lazithunzi, mtundu wamtundu, ndi zolemba. Chifukwa chake, pachitsanzo ichi, ndipanga wosanjikiza watsopano podina "Pangani chithunzi chatsopano" (chomwe chikuwonetsedwa ndi muvi wofiyira) ndikuchitcha "Green Layer." Ndiyika miyeso (m'lifupi ndi kutalika) kukhala ma pixel 500 ndi ma pixel 500 ndikukhazikitsa "Dzazani" mpaka "mtundu wakumbuyo" kuti mudzaze wosanjikiza ndi mtundu wakumbuyo womwe tasankha (wobiriwira wowala womwe takhala tikugwiritsa ntchito).

Pangani Gulu Lamalemba Pogwiritsa Ntchito Chida Cholemba

Ndipanganso wosanjikiza wamawu pogwira chida changa chalemba (chomwe chikuwonetsedwa ndi muvi wofiyira pachithunzi pamwambapa), kenako ndikudina zomwe ndalemba ndikulemba "Izi ndi zolemba."

Mukayang'ana pagawo la zigawo, muwona kuti tsopano tili ndi zigawo zitatu - chithunzithunzi, chosanjikiza chamtundu (chomwe chili chopanda kanthu chomwe chili ndi mtundu wakumbuyo), ndi zolemba.

Erasing Active Layer mu GIMP 2019

Ndiye, chimachitika ndi chiyani ndikafuna kufafaniza zobiriwira ku Green Layer yathu? Ngati ndidina pa chida changa chofufutira m'bokosi lazida ndikuyesera kufufuta zobiriwira, muwona kuti mawu anga okha ndi omwe amafufutidwa. Ndigunda ctrl+z kuti ndisinthe kufufuta uku.

Chinsinsi chothandizira kuti chida chanu chofufutira chizigwira ntchito mu GIMP (momwe mukufunira) ndikuwonetsetsa kuti mwadinda pagawo lililonse lomwe ma pixel ali pomwe mukufuna kufufuta. Popeza ndidadina pa Text layer (yomwe ikuwonetsedwa ndi muvi wobiriwira pachithunzi pamwambapa) pongofuna kufufuta, ma pixel omwe adachotsedwa palembalo adafufutidwa.

Konzani Chida Chofufutira sichikugwira Ntchito Zigawo Zambiri

Chifukwa chake, mwachitsanzo, popeza tikufuna kufafaniza ma pixel obiriwira, tiyenera kuwonetsetsa kuti tadinda pa Gulu Lobiriwira pagawo la zigawo (lomwe likuyimira muvi wobiriwira pachithunzi pamwambapa). Ndikangodina pamndandandawo (kupanga kukhala wosanjikiza wanga), tsopano nditha kufufuta ma pixel obiriwira okha (osati zolemba kapena ma pixel azithunzi).

Kufufuta Ma Pixels Kuchokera Pamagulu Angapo Nthawi Imodzi

Chitsanzo chapamwambachi chikukhudza momwe mungafufutire ma pixel pamagulu amodzi - koma bwanji ngati mukufuna kufufuta ma pixel pamagulu onse atatu nthawi imodzi?

Pali njira ziwiri zochitira izi - imodzi ndiyosavuta koma ndi njira "yowononga" yosinthira. Njira ina ndiyopita patsogolo pang'ono, koma ndi njira "yosawononga" yosinthira.

Njira 1 - Gwirizanitsani Pansi

Gwirizanitsani Chofufutira Pansi Yosagwira Ntchito

Panjira yoyamba, nditha kudina pomwe pagulu langa lapamwamba (zolemba) ndikudina "phatikizani pansi." Izi ziphatikiza zolemba zanga ndi Green Layer pagawo limodzi. Nditha kudina pagawo lophatikizidwa ndikusankhanso "kuphatikiza pansi." Izi ziphatikiza zigawo zanga zonse zitatu kukhala gawo limodzi.

Tsopano nditha kudina chofufutira changa m'bokosi langa lazida ndikuchotsa ma pixel kuchokera mu zigawo zonse zitatu nthawi imodzi. Vuto lokhalo ndiloti sindingathenso kusuntha zinthu pamtundu uliwonse chifukwa zonse zaphatikizidwa pamodzi pamtanda umodzi.

Njira 2 - Chigoba cha Gulu Losanjikiza

Njira yachiwiri, monga ndidanenera kale, ndiyotsogola kwambiri. Izi ndichifukwa chimagwiritsa ntchito gulu losanjikiza lophatikizidwa ndi chigoba chosanjikiza m'malo mwa chida chofufutira. (Zindikirani, njirayi idzagwira ntchito ku GIMP 2.10 kapena zatsopano. Sizigwira ntchito ku GIMP 2.8).

Pangani gulu losanjikiza mu GIMP 2 10 12

Poyamba, ndidina chizindikiro cha "New layer group" kuti ndipange chikwatu chatsopano chamagulu pagawo langa (lomwe likuwonetsedwa ndi muvi wofiyira pachithunzi pamwambapa).

Kenako, ndidina ndikukokera wosanjikiza aliyense mu gulu la wosanjikiza (yambani ndi wosanjikiza wapansi kwambiri poyamba, ndikukwera mpaka pamwamba - monga ndidachitira pachithunzi pamwambapa, chosonyezedwa ndi muvi wobiriwira. onetsetsani kuti zigawo zomwe zili mkati mwa gululo zizikhala bwino).

Onjezani Chigoba cha Gulu la Gulu mu GIMP 2 10

Tsopano, nditha kudina kumanja pagulu losanjikiza ndikupita ku "Add Layer Mask."

Eraser Not Working Solution Layer Mask Option GIMP

Pansi pa "Initialize Layer to:" Ndisankha "White: Opacity Full." Ndidina "Add" kuwonjezera chigoba wosanjikiza.

Paint Black pa White Layer Mask GIMP 2019

Tsopano gulu lathu losanjikiza lili ndi chigoba. Chigobacho ndi choyera, zomwe zikutanthauza kuti tikhoza kuwona ma pixel onse oyambirira kuchokera m'magulu athu atatu. Komabe, ngati ndipaka zakuda pachigoba chosanjikiza, zimagwira ntchito ngati chofufutira. Chifukwa chake, nditenga burashi (muvi wabuluu), ndisinthe mtundu wakutsogolo kukhala wakuda, ndikuwonetsetsa kuti ndadindidwa pa chigoba chosanjikiza (muvi wofiyira).

Madera omwe ndidapaka utoto wakuda tsopano awonetsa kuwonekera pachithunzi changa, ndikuchotsa ma pixel onse mu zigawo zonse zitatu nthawi imodzi. Chifukwa chomwe izi zimawonedwa ngati "zosawononga" kuposa njira yoyamba ndikuti nditha kubwerera nthawi iliyonse ndikupaka zoyera pachigoba changa chosanjikiza kuti ndibweretse ma pixelwo, kapena kungochotsa chigoba chonsecho.

Kutsegula Ma Pixels Osanjikiza ndi Alpha Channel

Ngati palibe njira yomwe ili pamwambayi yomwe yathetsa chofufutira chanu sichikugwira ntchito, musadandaule - padakali mutu umodzi woti muwunike apa. Chida chofufutira sichingagwire ntchito ngati muli ndi ma pixel kapena kuwonekera pagawo lina lokhoma.

GIMP Lock Pixels Njira

Kubwerera ku magawo athu atatu (ndisanawawonjeze ku gulu losanjikiza), nditha kudina Green Layer yanga ndikusankha "Lock pixels" mugawo la "Lock" la gulu la zigawo (lomwe likuyimira muvi wofiyira). ).

Ma Pixel a Active Layers Atsekedwa

Tsopano, ndikayesa kufufuta ma pixel omwe ali pagawoli, ndimalandira uthenga wolakwika mumutu wanga wamutu ndi Status bar (pansi pa zenera la zithunzi za GIMP) wonena kuti "Ma pixel omwe akugwira ntchito atsekedwa." Mwa kuyankhula kwina, sitingathe kusintha ma pixel omwe ali pamtanda pomwe ma pixel atsekedwa - ndipo izi zikuphatikizapo kuyesa kuchotsa ma pixel.

Nditsegula ma pixels pamzerewu podinanso chizindikiro cha "lock pixels" pomwe Green Layer ikadali wosanjikiza wanga.

Active Layers Alpha Channel Yatsekedwa

Ndithanso kutseka njira ya alpha pagawo lobiriwira podina chizindikiro cha "Lock alpha channel" (chomwe chikuwonetsedwa ndi muvi wofiyira). Izi zigwira ntchito yofanana ndi chithunzi cha "Lock pixels", kupatula kuti ingotseka njira yanga ya alpha - kapena kuwonekera pachithunzi changa. Nditha kupentabe pansanjika iyi ndi china chake ngati chida chopenta, koma sindingagwiritse ntchito chofufutira changa pagawoli. Ndikayesa kugwiritsa ntchito chofufutira changa pomwe njira ya alpha ili yokhoma, ndimapeza uthenga pamutu wanga wamutu ndi Status bar wonena kuti "Channel yogwira ya alpha yatsekedwa" (yomwe imadziwika ndi muvi wabuluu).

Kuti mutsegule tchanelo cha alpha, nditha kuonetsetsa kuti ndadina pa Gulu Lobiriwira kenako ndikudinanso chizindikiro cha "Lock alpha channel". Njira ya alpha iyenera kutsegulidwa, ndikundilola kuti ndifufutenso ma pixel pagawoli.

Ngati mukukumanabe ndi zovuta ndi chofufutira chanu, kuyika kwanu kwa GIMP kungakhale ndi cholakwika - chomwe ndikupangira lipoti ku gulu la GIMP.

Ndizo za phunziro ili! Ngati munasangalala nazo, mutha kuyang'ananso zanga zina Zolemba zothandizira za GIMP patsamba langa, komanso chilichonse changa Maphunziro avidiyo a GIMP. Mukhozanso kulembetsa aliyense wanga Maphunziro a GIMP.
