M'nkhaniyi ndikuwonetsani momwe mungapangire gradient yowonekera pogwiritsa ntchito GIMP. Imeneyi ndi njira yosavuta kwambiri, yabwino yoyambira yomwe imakulolani kuti chithunzi chanu "chizimiririke" pang'onopang'ono kuti chiwonekere, kapena kuchotsa pang'onopang'ono chithunzicho.

Mukhoza kutsatira pogwiritsa ntchito chithunzi chaulere chomwe ndidatsitsa kuchokera ku Unsplash apa. Mutha kuwonera kanema wamaphunzirowa pansipa, kapena kupitilirapo kuti mupeze chithandizo chonse. Tiyeni tiyambe!

M'ndandanda wazopezekamo

Khwerero 1: Tsegulani Chithunzicho mu GIMP

Kuti muyambe, mudzafuna kulowetsa chithunzi chanu mu GIMP ngati simunatero. Mutha kuchita izi popita ku Fayilo> Tsegulani, ndikusankha malo omwe mafayilo ali pakompyuta yanu. Muthanso kukoka ndikugwetsa chithunzi chanu m'gawo lalikulu la GIMP (tsatirani mivi yofiira pamzere wa madontho obiriwira pachithunzi pamwambapa).

Chithunzi chanu chikakhala mu GIMP, mutha kufunsidwa ngati mukufuna kusintha chithunzicho kukhala malo amtundu wa sRGB wa GIMP. Ndikupangira kumenya "Convert" (muvi wofiyira pachithunzi pamwambapa) pokhapokha ngati mufunika kusunga malo amtundu wa chithunzicho pazifukwa zinazake.

Gawo 2: Onjezani Alpha Channel

Ndi chithunzi chomwe chatumizidwa ku GIMP, mudzafuna kumaliza gawo lofunikira pakuwonjezera njira ya alpha pazithunzi zanu. Kuti muchite izi, dinani kumanja pazithunzi zomwe zili pagawo la "Layers" (muvi wofiyira) ndikudina "Add Alpha Channel" (muvi wobiriwira). Gawo ili ndilofunika chifukwa popanda njira ya alpha yowonjezeredwa pachithunzi chanu, chithunzi chanu chidzafafanizidwa ndi mtundu m'malo mowonekera.

Khwerero 3: Onjezani Chigoba Chosanjikiza pa Chithunzi Chanu

Ndi njira yanu ya alpha yowonjezeredwa, chotsatira chomwe mukufuna kuchita ndikuwonjezera chigoba chosanjikiza pachithunzi chanu. Izi zikuthandizani kuti musawonjezere gradient "yowonekera" pachithunzi chanu. Kuti muwonjezere chigoba chosanjikiza, dinani chizindikiro cha chigoba chosanjikiza pansi pagawo la zigawo (muvi wofiyira pachithunzi pamwambapa). Mukhozanso dinani kumanja pazithunzizo ndikusankha "Add Layer Mask."

Munkhani ya Layer Mask yomwe ikuwonekera, pansi pa "Initialize Layer Mask To:" sankhani "White (Full Opacity)" (muvi wobiriwira pachithunzi pamwambapa). Dinani batani la "Add" pansi pa zokambirana (muvi wabuluu).

Tsopano muyenera kuwona bokosi loyera kumanja kwa chithunzithunzi chanu pagawo la Zigawo (muvi wofiyira pachithunzi pamwambapa). Bokosi loyera ili ndi chigoba chanu chosanjikiza.

Khwerero 4: Jambulani Gradient Pachigoba Chanu Chosanjikiza

Kenako, gwirani chida cha Gradient m'bokosi lazida zanu podina ndikugwira mbewa yanu pagulu lazida lomwe lili ndi Chida Chodzaza Chidebe (muvi wofiyira pachithunzi pamwambapa), kenako ndikutulutsa mbewa yanu pa chida cha "Gradient" (muvi wabuluu). Muthanso kungogunda kiyi ya "G" pa kiyibodi yanu kuti mupeze chida ichi kudzera pa kiyi yachidule.

Ndi chida chosankhidwa, dinani kachizindikiro kakang'ono pansi pamitundu yakutsogolo ndi yakumbuyo kwanu (kumunsi kwa Toolbox - muvi wofiyira pachithunzichi) kuti musinthe mitundu yanu kukhala yakuda ndi yoyera.

Tsopano, bwerani ku gawo la "Tool Options" la chida cha Gradient (nthawi zambiri chimakhala pansi pa Toolbox yanu - ngati sichikuwoneka pitani ku Windows> Zokambirana Zowoneka> Zosankha Zachida). Dinani batani la "Gradient" (muvi wofiyira pachithunzi pamwambapa) ndikusankha imodzi mwama gradients omwe amasintha kuchokera kukuda kupita ku zoyera (zofotokozedwa mubuluu) - ndidapita ndi njira ya "FG to BG (RGB)" ndikungodinanso pamenepo. .

Dinani kutsika kwa "Shape" (muvi wofiira) ndikusankha "Linear" (muvi wabuluu).

Pomaliza, dinani ndi kukoka mbewa yanu pamapangidwe anu kuti mujambule gradient (nsonga: gwirani kiyi ya ctrl pa kiyibodi yanu kuti mujambule mowongoka). Chithunzi chanu chikuyenera kuwoneka ngati chikuzimiririka, kapena kufufuta, kuti chiwonekere pogwiritsa ntchito gradient.

Zindikirani: nthawi zonse mutha kutembenuza mayendedwe a gradient pogwiritsa ntchito batani la "Reverse" mu Tool Options (muvi wobiriwira pachithunzi pamwambapa). Kenako mutha kudina ndi kukoka ma gradient kuti muwakhazikitsenso pachithunzi chanu.

Mbali imodzi ya gradient idzakhala ndi zoyera, zomwe zimakhala ndi kuwala kapena kuwonetsera ma pixel mu fano lanu, ndipo mapeto ena a gradient anu adzakhala ndi zakuda, kapena zowonekera zomwe zimabisa chithunzi chanu. Muchitsanzo ichi, mbali yakumanzere ya gradient yanga ili ndi zoyera (muvi wofiyira pachithunzi pamwambapa), ndipo kumanja kwa gradient kuli zakuda (muvi wabuluu pachithunzichi).

Nditha kudina ndikukokera kumapeto ndi mbewa yanga kuti ndisinthe nthawi yomwe kuzimiririka kumayambira, ndipo pomwe chithunzicho chazimiririka ndipo tsopano chikuwonekera.

Mukayika mbewa yanu pamzere pakati pa mathero awiriwo, mudzawona bwalo laling'ono likuwonekera chapakati pa mzere (muvi wofiyira). Uwu ndiye "pakati" wa gradient yanu.

Mutha kudina ndi kukoka pakati kuti musinthe pomwe chithunzicho chili pa 50% opacity, chomwe chimasintha kuchuluka komwe chithunzicho chimazimiririka kuti chiwonekere. Mwachitsanzo, ndikakokera chapakati kumanzere, chithunzi changa chidzayamba kuzimiririka kuti chiwonekere posachedwa.

Mukakonzeka kugwiritsa ntchito gradient, dinani batani lolowera pa kiyibodi yanu. Ngati gradient sikugwira ntchito mukamenya fungulo lolowera, ingogwirani chida china kuchokera mu Toolbox ngati chida cha "Sungani".

Ngati muyang'ana chithunzi cha chithunzi cha wosanjikiza wanu pagawo la Layers (muvi wofiyira pachithunzi pamwambapa), muwona bokosi loyera lili ndi gradient yomwe imasintha pang'onopang'ono kuchoka ku zoyera kupita zakuda (kapena zakuda kukhala zoyera, kutengera komwe gradient akupita). Chithunzi chanu tsopano chimazimiririka pang'onopang'ono mpaka kuwonekera pogwiritsa ntchito gradient!

Khwerero 5: Tumizani Chithunzicho ndi Transparency

Ngati mukufuna kutumiza chithunzicho NDI kuwonekera bwino kwa gradient, mutha kutero mwa kungopita Fayilo> Tumizani Monga (muvi wofiyira), kenako tumizani chithunzicho ngati mtundu wa fayilo womwe umathandizira kuwonekera (zitsanzo zina ndi PNG, WebP, GIF, ndi TIFF).

Kotero, ngati ndikufuna kutumiza chithunzi changa monga PNG, ndikhoza kutchulanso fayilo yanga ndikuonetsetsa kuti ikutha ndi ".png" (muvi wofiira) - kufalikira kwa fayilo ya PNG. Dinani "Tumizani" kuti mutumize chithunzicho (muvi wobiriwira).

Mutha kumamatira ndi zikhalidwe zosasinthika za PNG ndikudina "Tumizani" kachiwiri (muvi wofiyira), ndipo tsopano chithunzi chanu chidzatumizidwa kunja ndi gradient yowonekera.

Ndizo za phunziro ili! Ngati munakonda, mutha kuyang'ananso zanga zina Zolemba Zothandizira za GIMP, Maphunziro avidiyo a GIMP, kapena ngakhale wanga GIMP 2.10 Masterclass pa Udemy!
