Monga tafotokozera kale mwachidule mndandandawu, zigawo zimatha kukhala zowonekera mosiyanasiyana, kapena zitha kukhala zosawoneka bwino. Ili ndi lingaliro lofunikira chifukwa zigawo zowonekera zimalola kuti mapangidwe akhale ovuta kwambiri komanso okhala ndi kuzama, komanso amalola nyimbo kuti zisungidwe popanda maziko.

Layer Transparency mu GIMP Zigawo Zitatu

Kuti ndimvetsetse bwino lingaliro ili la kuwonekera, ndili ndi zigawo zitatu zomwe zatsegulidwa muzolemba zanga (zowonetsedwa zobiriwira pachithunzi pamwambapa). Gawo loyamba ndi Layer 1 - lomwe lili pamwamba panga wosanjikiza okwana ndipo ndi wosanjikiza poyera. Chosanjikiza chachiwiri ndi chithunzi - chotchedwa "Model in Red Chair," chomwe ndi chosawoneka bwino ndipo sichikhala ndi kuwonekera (zambiri pa izi mumphindikati). Gawo lachitatu ndi Background layer yathu, yomwe ilinso yosawoneka bwino koma yodzaza ndi zoyera. Chigawochi chilibenso zowonekera.

Kusintha Layer Transparency ndi Opacity Slider

Kusintha Opacity Slider mu GIMP 2019

Pali njira zingapo zowongolera ndi kuwonekera kwa wosanjikiza, zotsatira zake zimatengera momwe mukulumikizirana ndi kuwonekera kwa wosanjikiza. Mwachitsanzo, ndikadina pa Model mu Red Chair wosanjikiza (yomwe imadziwika ndi muvi wobiriwira), nditha kugwiritsa ntchito chowongolera cha opacity pamwamba pagawo la Zigawo (muvi wofiyira) kuti ndisinthe mawonekedwe onse a gululi. Mwachikhazikitso, slider imayikidwa ku 100 - kutanthauza kuti ili ndi 100% opacity kapena ndi opaque kwathunthu. Ngati ndikokera slider kumanzere, chiwerengerocho chimakhala chochepera 100, zomwe zikutanthauza kuti chithunzicho chili ndi kuwonekera.

Ngati ndikoka chotsetsereka mpaka chikafika pamtengo wa 50 (monga momwe zasonyezedwera pachithunzichi), zikutanthauza kuti chithunzicho ndi 50% opaque ndi 50% yowonekera. Ichi ndichifukwa chake titha kuwona kupyola mumsewuwu, ndikuwulula zoyera kumbuyo kwake (zomwe zimapangitsa kuti chithunzi chathu chiwoneke chopepuka, popeza kuwonjezera zoyera pamapikseli anu onse kumawunikira ma pixel awo).

Sinthani pamanja mtengo wa opacity slider mu GIMP

Ndithanso kulemba pamanja mtengo mu slider yanga yosawoneka ngati ndikufuna nambala yeniyeni apa. Kuti ndichite izi, ndikungofunika kugwiritsa ntchito mbewa yanga kuti ndiwonetsere mtengo wapano (wakhazikitsidwa ku 50.0 pakali pano), kenako lembani nambala yanga yatsopano ndikugunda kiyi yolowera. Mwachitsanzo, ndilemba 23 kuti ndikhazikitse mtengo wanga wosawoneka bwino kukhala 23% ndi mtengo wanga wowonekera kukhala 77% (monga momwe zasonyezedwera m'dera lomwe lawonetsedwa zobiriwira pachithunzi pamwambapa).

Pa cholemba ichi, ndikufuna kunena kuti pali mgwirizano wosiyana pakati pa kuwala ndi kuwonekera - kapena mwa kuyankhula kwina mtengo wa chimodzi mwa miyeso iyi nthawi zonse ndi mtengo wa muyeso wina wochotsedwa ku 100. Kotero, ngati kusawoneka kwanga pakuti wosanjikiza wanga wakhazikitsidwa ku 65%, wosanjikiza wanga ndi 35% wowonekera. Ngati wosanjikiza wanga ndi 40% wowonekera, ndiye kuti kuwala kwake kuyenera kukhazikitsidwa ku 60%. Ayi masamu.

Gwiritsani ntchito mivi yotsetsereka yosawoneka bwino kuti muwonjezere kapena kuchepetsa kuwala

Nditha kugwiritsanso ntchito mivi yomwe ili kumanja kwa opacity slider (yomwe ikuwonetsedwa ndi muvi wofiyira) kuti ndiwonjezere kapena kuchepetsa kusawoneka ndi 1 peresenti. Chifukwa chake, ndikadina muvi wapansi kamodzi, kusanja kwanga kudzakhala 22%. Ndikadina muvi wokwera kawiri, kusanja kwanga kumakhala 24%.

Zindikirani: pamene kusanja kwanga kosanjikiza kukhazikitsidwa ku 0%, sikudzawonekanso chifukwa kudzakhala kowonekera kwathunthu. Kuwonekera kwanga kosanjikiza sikungakhale kochepera 0% kapena kupitirira 100% - kumagwa nthawi zonse.

100 Opacity GIMP wosanjikiza Transparency Tutorial

Pa gawo lotsatira la phunziroli, ndikukhazikitsa kusanja kwanga kwanga ku 100% (mutha kukoka chowonera cha opacity mpaka kumanja kapena lembani pamanja mtengo wa "100").

Alpha Channels ndi Layer Transparency

Lingaliro lotsatira lofunikira pankhani yowonekera ndi chinthu chotchedwa Alpha channel.

GIMP Channels Dialogue

Zolemba mu GIMP nthawi zonse zimakhala ndi njira zina zodziwira momwe mitundu idzawonetsedwera pakupanga. Makanemawa amapanga zomwe zimatchedwa Colour Space. Malo omwe amagwiritsidwa ntchito kwambiri, komanso malo osasinthika amtundu mu GIMP, ndi malo amtundu wa RGB. Izi zikutanthauza kuti chithunzi chanu chili ndi njira zitatu zamitundu - Red, Green, ndi Blue (ndicho chifukwa chake timagwiritsa ntchito mawu oti "RGB"). Mutha kuwona matchanelo amitunduyi popita ku tabu ya "Channel" pafupi ndi tabu yanu ya "Layers" m'dera la "Layers, Channels, Paths, Rendo History" (lomwe likuyimira muvi wofiyira pachithunzi pamwambapa).

Apa, mutha kuwona tili ndi njira yofiyira, yobiriwira, ndi yabuluu, iliyonse itayikidwa pamwamba pa inzake monga momwe timayikamo zigawo. Komabe, muwona kuti palinso njira yachinayi yomwe ikuwoneka pano - njira ya Alpha. Njirayi ikuyimira kuwonekera kwenikweni kwa gulu. Ngati gawo lilibe njira ya Alpha, silingathe kutulutsa madera akutali akuwonekera.

Mwanjira ina, titha kuchepetsa kusanja kwa gawo lonse nthawi imodzi (monga tidachitira ndi chowonera cha Opacity koyambirira kwa nkhaniyi), koma sitingathe kutenga chida ngati chida chofufutira ndikupanga kagawo kakang'ono kowonekera. wosanjikiza.

Izi zikunenedwa, popeza titha kuwona kuti pali njira ya Alpha yolumikizidwa ndi gawo lomwe tikukhalamo (chithunzi chathu chazithunzi), tiyenera kutulutsa gawo lakutali lowonekera, sichoncho? Chabwino - ndizovuta kwambiri kuposa izo.

Zigawo za Panel Model Mu Red Chair Layer

Ngati ndibwerera ku gulu la zigawo (muvi wofiyira pachithunzi pamwambapa), muwona kuti ndikudinabe Model yanga mu Red Chair (muvi wobiriwira).

Kufufuta Malo a Chithunzi Popanda Kuwonekera

Tsopano, ngati ndigwira chida changa chofufutira m'bokosi lazida (muvi wofiyira pachithunzi pamwambapa), ndikufufuta malo osanjikizana anga, mudzawona kuti sikutulutsa kuwonekera komwe ndikufufuta. M'malo mwake amapaka utoto wakuda (muvi wabuluu pachithunzichi). Chifukwa chiyani?

Chabwino, mu GIMP muyenera kutchula gawo lililonse lomwe lilibe kuwonekera kuti mukufuna kuwonjezera njira ya alpha pagawolo ndikuwonetsetsa. Pakali pano, Gawo 1 lokha ndilomwe lili ndi kuwonekera chifukwa tidapanga gawo latsopano ndikudzaza maziko ndi kuwonekera (yenderani nkhani yapitayi komwe ndidapanga gawo ili). Ichi ndichifukwa chake njira ya Alpha idawonetsedwa muzokambirana zathu za Channels (ngakhale tidadina pa Model yathu mu Red Chair Layer - mwanjira ina zinali zosokeretsa chifukwa zimawoneka ngati Model yathu mu Red Chair layer inali ndi alpha channel ngakhale ayi).

Zigawo zina ziwiri zomwe zikuphatikizidwa, Model in Red Chair image layer ndi Background layer, zidapangidwa popanda kuwonekera (maJPEGs alibe kuwonekera, ndipo tidadzaza Background layer yathu ndi zoyera m'malo mowonekera pomwe tidazipanga koyamba).

Chifukwa chake ngakhale zikuwonetsa kuti njira ya Alpha ilipo pamapangidwe athu, imakhalapo pa Gawo 1. Tiyenera kupanga ma alpha pamanja pamagawo ena awiri. Kupanda kutero, tikamayesa kufufuta malo (mwina ndi chida chofufutira kapena ndi chida china ngati chida chosankha), malowa adzadzazidwa ndi mtundu wathu wakumbuyo, womwe ndi wakuda.

Onjezani Alpha Channel ku Layer mu GIMP 2 10

Kuti ndichite izi, zomwe ndiyenera kuchita ndikudina pomwe pagawo langa logwira ntchito (lomwe likuyimira muvi wofiyira), kenako dinani Add Alpha Channel (muvi wabuluu - ngati mungasunthire mbewa yanu panjira iyi, uthenga udzawonetsa kuti izi. adzakhala "Onjezani zowonekera ku wosanjikiza").

Dzina Lachingwe Silinso Lolimba Pamene Alpha Channel Iwonjezedwa

Mukawonjezera njira ya alpha pamndandanda, zinthu ziwiri zowoneka bwino zidzachitika pomwepo. Kumodzi, dzina la wosanjikiza wanu silidzakhalanso molimba mtima likakhala gawo lanu logwira ntchito (uku ndikusintha kosawoneka bwino, koma ngati mutachotsa Kuwonjezera Alpha Channel ndikuyang'ana dzina lanu losanjikiza, mudzawona kuti lili molimba mtima. font ikadindidwa kapena ikugwira ntchito. Mukuchitanso zochita zanu za Add Alpha Channel, font sikhalanso molimba mtima pamene wosanjikiza akugwira ntchito).

Chachiwiri chomwe mungazindikire ndichakuti mukadina pomwe pagawo, njira ya Add Alpha tsopano ikhala imvi - kapena yosagwira ntchito - pamenyu. Simungathenso kusankha njirayi chifukwa wosanjikiza wanu tsopano ali ndi njira ya alpha.

Chida cha GIMP Eraser Chimatulutsa Kuwonekera

Tsopano popeza tili ndi njira ya alpha, ndigwiritsanso ntchito chofufutira changa (muvi wofiyira) pagawo langa. Nthawi ino, m'malo mojambula zakuda, idzawonetsa mzere woyera (muvi wabuluu) womwe uli pansi pa Model yathu mu Red Chair layer.

Bisani Gulu Lakumapeto Kuti Muwonetse Kuwonekera

Ngati ndibisa Zosanjikiza Zakumbuyo podina chizindikiro chawonetsero/kubisa (muvi wofiyira), tsopano muwona bolodi yotuwa pamalo pomwe tidagwiritsa ntchito chofufutira chathu (muvi wabuluu). Derali likuyimira maziko owonekera. Izi zikutanthauza kuti palibe ma pixel ojambulidwa m'derali - ndizowona kwathunthu.

Zikafika popanga magawo azithunzi zanu kuti ziwonekere (mwachitsanzo, ntchito zodziwika ngati kufufuta maziko a chithunzi), kufufutika molunjika pagawo, monga tachitira apa, kumatchedwa "kuwononga" kusintha chifukwa tsopano tataya ma pixel onse omwe tangochotsa pachithunzi chathu (tikhoza kusintha zomwe zikuchitika pakali pano popeza zinali chomaliza chomwe tidachita, koma pali nthawi zina pomwe mutha kuchitapo kanthu musanazindikire kuti simukufuna kufafaniza).

Mwamwayi, pali njira ina "yosawononga" yofufutira mbali za chithunzi chanu ndikupanga kuwonekera. Ndifotokoza mutuwu m'nkhani yanga yotsatira ya Masks a Layer.

Ndizo za phunziro ili! Ngati munakonda, mutha kuyang'ananso zanga zina Zolemba Zothandizira za GIMP, penyani chilichonse changa Maphunziro avidiyo a GIMP, kapena kulembetsa chilichonse changa Maphunziro a Premium GIMP & Maphunziro.
