Zojambula za Photoshop nthawi zambiri zimagwiritsidwa ntchito polemba zithunzi.
Njira ndiyotchuka kwambiri kuti ngakhale ogwiritsa ntchito omwe sadziwa kwenikweni momwe pulogalamuyo imagwirira ntchito amatha kuthana ndi kutulutsa zithunzi.
Chinsinsi cha nkhaniyi ndi kusintha zithunzi mu Photoshop CS6, kuchepetsa kutsika kwake. Kusintha kulikonse kwa kukula koyambirira kudzakhudza mtunduwo, komabe, mungatsatire malamulo osavuta kuti musunge bwino chithunzicho ndikupewa "kusakanikirana".
Chitsanzo chimaperekedwa mu Photoshop CS6, m'mitundu ina ya CS momwe algorithm yochitira zinthu idzakhala chimodzimodzi.
Kukula kwa Zithunzi
Mwachitsanzo, gwiritsani ntchito chithunzichi:
Kukula koyambirira kwa chithunzi chomwe chinajambulidwa ndi kamera ya digito kunali kwakukulu kwambiri kuposa chithunzi chomwe chatchulidwa pano. Koma mchitsanzo ichi, chithunzichi ndi chosakhwima kotero kuti chitha kuyikidwa mosavuta mu nkhaniyi.
Kuchepetsa kukula mu mkonzi uno sikuyenera kuyambitsa zovuta zilizonse. Pali mndandanda wazinthu izi mu Photoshop "Kukula Zithunzi" (Kukula kwa chithunzi).
Kuti mupeze lamulo ili, dinani pa tabu lalikulu la menyu "Chithunzi - Kukula Zithunzi" (Chithunzi - Kukula kwa Zithunzi) Mutha kugwiritsanso ntchito ma hotkeys. ALT + CTRL + I
Nayi chithunzi cha menyu chomwe chatengedwa mutangotsegula chithunzicho mkonzi. Palibe kusintha komwe kwachitika, sikelo yasungidwa.
Bokosi la zokambirana ili ndi midadada iwiri - Mlingo (Miyeso ya pixel) ndi Sindikizani Kukula (Kukula Kwa chikalata).
Chophimba chapansi sichitikomera, popeza sichokhudzana ndi mutu wa phunziroli. Tembenukira kumtunda kwa bokosi la zokambirana, pomwe kukula kwa fayilo m'm pixel kukuwonetsedwa. Ndiwo mkhalidwe womwe umayang'anira kukula kwenikweni kwa chithunzichi. Poterepa, zigawo za chithunzicho ndi pixel.
Kutalika, Kukula ndi kukula kwake
Tiyeni tiwone mwatsatanetsatane tsambalo.
Kumanja kwa ndime "Makulidwe" (Miyeso ya pixel) ikuwonetsa kuchuluka kuchulukitsa, kosonyezedwa ndi ziwerengero. Amawonetsa kukula kwa fayilo yomwe ilipo. Titha kuwona kuti fanoli limakhalamo 60.2 M. Kalata M imayimira megabytes:
Ndikofunikira kumvetsetsa kuchuluka kwa fayilo yoyatsidwa ngati mukufuna kufananiza ndi chithunzi choyambirira. Nenani, ngati tili ndi njira zolemerera pazithunzi.
Komabe, izi sizikhudza kukula kwake. Kuti tidziwe zamtunduwu, tidzagwiritsa ntchito mawonekedwe ndi kutalika kwake. Makhalidwe azigawo zonse ziwiri akuwonetsedwa pix.
Kutalika (Kutalika) chithunzi chomwe timagwiritsa ntchito 3744 ma pix, ndi Kufikira (Kufikira) - 566 ma pix.
Kuti mumalize ntchitoyi ndikuyika chithunzi patsamba latsamba, ndikofunikira kuchepetsa kukula kwake. Izi zimachitika posintha kuchuluka kwa manambala mu graph. "M'lifupi" ndi "Msodzi".
Lowetsani mtengo wotsutsana ndi kutalika kwa chithunzi, mwachitsanzo Ma pix 800. Tikalowetsa manambalawa, tiwona kuti mawonekedwe achiwiri a chithunzicho asinthanso ndipo tsopano 1200 ma pix. Kuti mugwiritse ntchito kusintha, sinthani Chabwino.
Njira ina yolowera chidziwitso cha kukula kwa chithunzi ndikugwiritsa ntchito peresenti ndi kukula kwa chithunzicho.
Pazosankha zomwezo, kumanja kwa gawo lolowera "M'lifupi" ndi "Msodzi"Pali mndandanda wotsika kwa magawo a muyeso. Amayimirira pix (pix), njira yachiwiri yomwe ikupezeka ndi chidwi.
Kuti musinthe kuwerengera peresenti, ingosankha njira ina pazosankha zotsitsa.
Lowetsani nambala yomwe mukufuna "Chidwi" ndikutsimikiza ndikakanikiza Chabwino. Pulogalamuyi imasintha chithunzicho molingana ndi kuchuluka kwa kuchuluka kwake.
Kutalika ndi kupingasa kwa chithunzicho kungathenso kuganiziridwa mosiyana - mkhalidwe umodzi peresenti, wachiwiri muma pixel. Kuti muchite izi, gwiritsani fungulo Shift ndikudina mumunda womwe mukufuna. Kenako m'minda tikuwonetsa zofunikira - kuchuluka ndi ma pixel, motsatana.
Kusintha Kwa Zithunzi ndi Stretch
Mosakonzekera, menyu amakonzedwa mwanjira yoti mukayika mtengo wa m'lifupi kapena kutalika kwa fayilo, munthu wina amasankhidwa yekha. Izi zikutanthauza kuti kusintha kwa kuchuluka kwa manambala kumafunikanso kusintha kwa kutalika.
Izi zimachitika kuti tisunge mawonekedwe oyamba a chithunzi. Ndikumveka kuti nthawi zambiri zimakhala zofunikira kungolowetsa chithunzicho osasokoneza.
Kutambasulira chithunzicho kudzachitika ngati mungasinthe kutalika kwa chithunzicho ndikusiya kutalika kofanana, kapena musinthe mwatsatanetsatane. Pulogalamuyi ikukuwuzani kuti kutalika ndi mulifupi kumadalira ndipo kumasiyana mosiyanasiyana - izi zikuwonetsedwa ndi logo ya ulumikizowu kumalumikizidwe kumanja pazenera ndi ma pixel ndi maperesenti:
Kudalira pakati kutalika ndi mulifupi kumayimitsidwa mzere "Sungani kuchuluka" (Constrain Proportions). Poyambirira, mumakhala chizidindo bokosi, koma ngati mukufuna kusintha pazokha, ndikokwanira kusiya mundawo wopanda kanthu.
Kuwonongeka kwa bwino mukachuluka
Kusintha magawo azithunzi pazithunzi za Photoshop ndi ntchito yaying'ono. Komabe, pali ma nuances omwe amafunikira kudziwa kuti musataye mtundu wa fayilo yokonzedwa.
Pofotokozera mfundoyi momveka bwino, tigwiritsa ntchito chitsanzo chosavuta.
Tiyerekeze ngati mukufuna kusintha chithunzi choyambirira - chepetsa. Chifukwa chake, pawindo la pop-up la Image kukula ndimalowa 50%:
Mukatsimikizira ndi Chabwino pa zenera "Kukula Zithunzi" (Kukula kwa chithunzi), pulogalamuyi imatseka zenera la pop-up ndikugwiritsa ntchito makina osinthidwa ku fayilo. Poterepa, amachepetsa chithunzi ndi theka kuchokera kukula koyambirira m'lifupi ndi kutalika.
Chithunzichi, monga momwe mukuwonera, chatsika kwambiri, koma mawonekedwe ake sanavutike kwambiri.
Tsopano tikupitilizabe kugwira ntchito ndi chithunzichi, nthawi ino chikuwonjezera kukula kwake koyambirira. Ndiponso, tsegulani bokosi lofananira la Image Image. Timalowa ziwonetserozo, ndipo m'magawo oyandikana nawo timayendetsa angapo 200 - kubwezeretsa kukula koyambirira:
Tilinso ndi chithunzi chokhala ndi zofanana. Komabe, tsopano khalidwe silabwino. Zambiri zidatayika, chithunzicho chikuwoneka "chosadetseka" ndipo chataya kwambiri. Ndikupitilira kuwonjezera, zotayika ziwonjezeka, nthawi iliyonse ikachulukirachulukira.
Photoshop Algorithms for Scaling
Kuwonongeka kwa mtundu kumachitika pazifukwa chimodzi zosavuta. Mukamachepetsa kukula kwa chithunzicho pogwiritsa ntchito njira "Kukula Zithunzi"Photoshop imangochepetsa chithunzi pochotsa ma pixel osafunikira.
Algorithm imalola pulogalamuyo kuti iwunikenso ndikuchotsa ma pixel pazithunzi, ndikuchita izi popanda kutaya mtundu. Chifukwa chake, zikhadabo, monga lamulo, musataye kuthamanga ndi kusiyana konse.
China chake ndi kuwonjezeka, apa zovuta zikutiyembekezera. Pankhani yochepetsera, pulogalamuyo siyofunika kupanga chilichonse - ingochotsani owonjezera. Koma mukafuna kuwonjezera, muyenera kudziwa komwe Photoshop imapeza ma pixel ofunikira kukula kwa chithunzichi? Pulogalamuyo imakakamizidwa kusankha payokha kusankha kuphatikizidwa kwa pixel zatsopano, kungodzipangira mu chithunzi chomaliza.
Chovuta chonse ndikuti mukakulitsa chithunzicho, pulogalamuyo imafunika kupanga ma pixel atsopano omwe sanakhalepo kalekale pankhaniyi. Komanso, palibe chidziwitso choti chithunzithunzi chomaliza chiyenera kuwoneka bwanji, kotero Photoshop imangotsogozedwa ndi ma algorithms ake wamba pakumawonjezera pixel zatsopano pachithunzichi, ndipo palibe china.
Mosakayikira, opanga awa adalimbikira ntchito kuti abweretse algorithm iyi pafupi ndi abwino. Komabe, chifukwa cha mitundu yosiyanasiyana ya zithunzi, njira yokulitsira chithunzicho ndi njira yofikira yomwe imakupatsani mwayi wowonjezera chithunzicho osawonongeka. Nthawi zambiri, njirayi imabweretsa kutayika kwakukulu komanso kowopsa.
Kumbukirani - sinthanitsani chithunzicho ku Photoshop, pafupifupi osadandaula za kutayika. Komabe, kuwonjezera kukula kwa zithunzi kuyenera kupewedwa pakukonzanso chithunzi choyambirira.
