GIMP: Pangani Pulse Meter kuchokera ku Scratch

Moni kwa iwo omwe amatenga nthawi kuti atiwerenge, dzulo tidayankhula kuyang'anira bandiwifi ndipo timapanga (monga nthawi zonse) chithunzi chowonekera ndi zomwe tidapanga. Chifukwa cha chithunzicho winawake adatiyandikira kudzera pa imelo ndikutifunsa kuti timusonyeze momwe angapangire mita yolimbitsa thupi, zimawoneka ngati lingaliro labwino kotero lero tikhala tikuwonetsa momwe tingapangire izi pogwiritsa ntchito pulogalamu yaulere komanso makamaka: GIMP.

Lingaliro lopanga mita yamagetsi m'malo mwake lidabwera kwa ife kuti tiwonetse kuti tikayeza china chake pamanambala, chifukwa chake tidasankha mawonekedwe ndipo "tidapanga" mita yoyeserera kuchokera pamenepo. Masitepe oti mukwaniritse china chonga ichi atsalira pansipa

Kupanga mawonekedwe oyambira ndi GIMP

Gawo loyamba mutatsegula fayilo ya Pulogalamu ya GNU Image Manipulator (GIMP potchulidwira mu Chingerezi) ndikupanga chithunzi chatsopano.

Kotero tiyeni tipite ku menyu Archivo » Watsopano kapena ngati tikufuna kuphatikiza kiyi, ingogwiritsani ntchito Ctrl + N. Timasankha kukula komwe akufuna koma kuwawonetsa tidzagwiritsa ntchito pixels 640 × 400 zomwe sizikulu kapena zazing'ono.

Timasankha mtundu womwe tikufuna podina bokosi lazosankha ndikusankha chimodzi mwazomwe timakonda kenako ndikukoka utoto kuchokera kubokosi kupita pazenera lazithunzi. Izi zikachitika timapanga gawo latsopano mosabisa (kugwira ntchito ndi zigawo ndikulimbikitsidwa kuti kufulumizitse njira zowongolera popanda kutaya ntchito yonse). Kuti tipeze chosanjikiza chatsopano timadina pazosanjikiza zomwe zili ndi chikwangwani chowonjezera kapena atolankhani kuloza + Ctrl + N kuti tipeze china chonga ichi:

Tili kale ndi mawonekedwe atsopano ndipo tikamagwira ntchito timapanga mawonekedwe omwe angatithandizire kuphatikiza mita. Choyandikira kwambiri pazida izi zomwe timadziwa ndi zida zamagetsi zomwe mawonekedwe ake ndi ozungulira kotero timatenga chida chosankhira (E) ndikupanga bwalo lozungulira lomwe timadzaza ndi mtundu uliwonse kuti tikhale ndi mawonekedwe oyenera kugwirira ntchito.

Kupanga gulu lamagulu

Timakhazikitsanso gawo latsopano koma nthawi ino sitiyenera kupanga chozungulira koma tidzagwiritsa ntchito mawonekedwe oyambira ndipo kuchokera pamenepo tipanga chomwe chingakhale thupi kapena m'mphepete mwa zida. Kuti tichite izi, dinani kumanja pazosanjikiza ndi mawonekedwe oyambira ndikuyang'ana pazosankha zomwe zingasankhe "Alpha to Selection".

Tikasankha mawonekedwe oyambilira timabwerera kuzitsulo zatsopano zomwe tidapanga koma tisanadzaze ndi utoto timapita kumenyu Sankhani ndipo timagwiritsa ntchito mwayi wa Lowani o Sakanizani ndi mtengo wa pixel 1. Timasankha mtundu womwe tikufuna wosanjikiza watsopano ndikudzaza.

Pakadali pano tili ndi mawonekedwe oyambira mumdima wina wosanjikiza wina ndi thupi la timu mumtundu wina (makamaka mumtundu wosiyana ndi wakumbuyo). Tili pamtunda wosanjikiza ndipo tipita fyuluta » Zosokoneza » Chisokonezo cha Gaussian Ndi mtengo wa pixel 5 ndipo tili ndi mthunzi, zotsatira zake ziyenera kukhala zocheperako:

Kupanga zamkati mwa gululi

Ndikutembenukira pakupanga mkati mwa zida, zomwe ndizovuta kwambiri chifukwa tidzagwiritsa ntchito maski osanjikiza, kudzaza mawonekedwe ndi chinyengo chowoneka ngati voliyumu ndikufanizira chivundikiro chachikale cha akiliriki.

Kupanga zamkati timapanga zosanjikiza zatsopano ndikubwerera ndimagwiridwe omwewo a Alfa posankha pokha pokha timagwiritsa ntchito gulu lakuthwa. Timabwerera kumalo atsopano komanso pamndandanda Sankhani » Sakanizani Timagwiritsa ntchito kukula kwa pixels pafupifupi 5 kenako timayang'ana mtundu womwe tidzagwiritse ntchito poyang'ana pakompyuta.

Timadzaza utoto ndikupitiliza kupanga zida zomwe zingakhale mu "chilankhulo cha GIMP" zomwe sizingadutse gridi. Timapanga gawo latsopano ndipo tidzatero Zosefera » Kupereka » Ntchito » Pachithandara Timasankha mtundu (makamaka wobiriwira) wosiyana ndi komwe zidapangidwazo ndipo timagwiritsa ntchito zotulukapo.

Timapanga zodzaza ngati gridi koma imakuta gawo lonse kotero timayenera kudula kotero kuti ili mkati mwamakanema apakompyuta.

Kudula grid timabwerera ndi Alfa posankha pogwiritsa ntchito ngati maziko osanjikizika kwa zida (zomwe timayika zobiriwira) kenako ife Sankhani » Sinthani kusankha kapena ngati titikakamiza Ctrl + I izi zikachitika timakanikiza fungulo DZIWANI ndipo voila… gridiyo ikugwirizana ndi chinsalu chomwe timayang'ana.

Kuti tithandizire kusintha, timasintha njira yosanjikiza ya gululi kuchokera Normal a Vuto ndipo tidatsitsa kuwonekera kwa 40% kuti tichotse "mphamvu" pang'ono.

Chophimba cha timu yathu

Mgulu lathu lomwe timayesa tidzayeza kuyerekeza ndi kuyerekezera makanema omwe amawonetsa malo a odwala pogwiritsa ntchito mzere, motero tidzapanga mzere wathu woyezera ndi zomwe zikugwirizana nawo. Kupanga mzere tidzagwiritsa ntchito chidacho Njira kenako tidzapanga mzere kuchokera njira yomwe tidapanga.

Choyamba timasankha mtundu womwe tikufuna pa Njira. Timasankha chida Njira ndipo timapeza mawonekedwe omwe tikufuna kuwapatsa.

Kamodzi mawonekedwe omwe tikufuna kupatsa Njira ndiye timapitiliza kugwiritsa ntchito zida zomwe tingagwiritse ntchito popanga mzere m'njira yonse yomwe tikufotokozera

Zingakhale zocheperako motere:

Njirayo ikadakonzedwa, timatsanzira mzerewo (womwe timagwiritsa ntchito ndi utoto womwe umawonekera pazenera lathu) mpaka pamizere pansipa yomwe timapanga fyuluta » Zosokoneza » Chisokonezo cha Gaussian ndipo timapitilira kukagwira ntchito pazosanja pamwambapa.

Kuti tipeze zotsatira zowoneka bwino pa Pulse timapanga chigoba chosanjikiza (dinani kumanja wosanjikiza » Onjezani maski wosanjikiza) ndipo timasankha mitundu yosasintha yamitundu (D). Izi ziyika bokosi loyera pafupi ndi gawo lathu.

Pambuyo pake timasintha Mitundu Yoyang'ana Patsogolo (Yoyera) ndi Yoyambira (Yakuda), dinani kumanja pazatsopano ndikusankha Onetsani chigoba chosanjikiza. Izi zitisiyira opanda kanthu koma osadandaula. Timasankha fayilo ya Chida Chosintha (tiyenera kukhala ndi mwayi wa Zowonjezera Bilinear) ndipo timakoka mzere ndikuugwiritsa ntchito kuchokera pakatikati pa wosanjikiza mosanjikiza.

Sitimasankha kusankha Onetsani chigoba Chosanjikiza. Ngati tiyang'ana pazokambirana tidzawona chonga ichi:

Pochita izi timawona kuti mzere wathu wapamwamba ukuwonekeranso ndipo zotsatira zake ndi zabwino.

Zindikirani kuti tsopano m'mbali mwa mzerewu muli ndi mtundu wa masanjidwewo, ngati kuti ukuzimiririka. Izi zitha kukhala zabwinoko.

Chivindikiro cha akiliriki cha zida

Monga tanenera pachiyambi, tidzapanga chinyengo kuti ili ndi mawonekedwe a akiliriki owonekera, omwe amapereka lingaliro ku voliyumu ku gulu, chifukwa chake tifunikira gloss wosanjikiza akiliriki komanso mthunzi wake wamkati.

Kuti tikwaniritse mthunzi wamkati timapanga gawo latsopano ndikupanga sitepe ya Alfa posankha pogwiritsa ntchito wosanjikiza pansi pazenera kenako timabwerera kuzitsulo zatsopano ndikuchepera (Sankhani »Sakanizani) ndi mtengo wa pixel 1.

Chisankhocho chikuchepa, timadzaza chakuda. Pambuyo pake, pamtundu womwewo wakuda, timachita gawo la Alfa posankha ndipo tibwerera ku Sankhani »Chepetsani nthawi ino ndi phindu la mapikiselo awiri. Mudzawona kuti tili ndi bwalo lakuda lomwe latsala, timagwiritsa ntchito a fyuluta » Zosokoneza » Chisokonezo cha Gaussian ndi mtengo 5 womwe timapezako china chonga ichi:

Ndikutembenukira pakupanga chivindikiro cha akiliriki chomwe timapangira gawo latsopano ndikuchita zomwezo Alpha Kusankhidwa pogwiritsa ntchito mawonekedwe osanjikiza pazenera.

Timasankha chida Wokhumudwa kuyika utoto woyera pamwamba pa wakuda, ndipo pazosankhazo timasankha mawonekedwe Linear ndi masinthidwe amtundu kuchokera Kukumana ndi Kuchita Zinthu Mwachilungamo, ndiye timayigwiritsa ntchito kuyambira pamwamba mpaka pansi kuyesera kukhala ndi mawonekedwe owongoka momwe angathere:

Kuti tiwoneke bwino tikuchepetsa kukula kwa glitter kuti likhale laling'ono ndikupangitsa kuti liziwoneka ngati gawo la akiliriki, lomwe limamaliza maphunziro athu ndi zotsatira zake zonse:

Pakadali pano maphunziro athu ochepa, tikukhulupirira kuti mudzakhala achimwemwe ndikuyesera kuti muchite.
