I-Valable Vector Graphics Rotate Umsebenzi
Ukujikeleza umfanekiso kuya kutshintsha i-angle apho umfanekiso ukhonjiswa khona. Ngeemifanekiso ezilula, oku kungongeza ezinye iindidi kunye nomdla kwinto enokuthi ibe yinto engqalileyo okanye embi. Njengokuba kukho konke ukuguqulwa, ujikeleze imisebenzi njengenxalenye yefowuni okanye umfanekiso wesimo. Ukufunda indlela yokusebenzisa ukujikeleza kwi- SVG, okanye i-Scalable Vector Graphics , ikuvumela ukuba ucele i-angle ecacileyo kwindlela yokuyila kwimilo yakho. I-SVG ijikeleza umsebenzi isebenza ukuguqula umfanekiso nakwezinye izikhokelo.
Ngokujikeleza
Umsebenzi wokujikeleza uwonke malunga nekota yomzobo. Xa uyila umfanekiso we- SVG , uza kudala imodeli ye-static emele ihlale kwindawo engokwemveli. Umzekelo, isikwere siya kuba namacala amabini kunye ne-X-axis kunye ezimbini kunye ne-Y-axis. Xa ujikeleza, ungathatha eso sikwere kwaye uguqule ibe yidayimani yokubunjwa.
Ngaloo mphumela owodwa, usuke ebhokisini eliqhelekileyo (eliqhelekileyo kwiiwebhsayithi) kwidayimani, engaqhelekanga kuyo yonke into kwaye engenakongeza izinto ezibonakalayo ezinomdla kwizinto eziyiyo. I-Rotate inxalenye yendawo yokukhupha i-SVG. Isangqa singajika rhoqo ngelixa siboniswa. Esi sikhokelo sinokuqwalasela iindwendwe kunye nokukunceda ukuba ugxininise amava abo kummandla oyintloko okanye izinto eziyilo loyilo.
I-Rotate isebenza kwimfundiso yokuba enye ichaphaza emfanekisweni iya kuhlala ihleli. Khawucinge ngecandelo lephepha elixhomekeke kwikhadibhodi nge-pin-pin. Indawo yenkcazo yindawo echanekileyo. Ukuba uphendulela iphepha ngokubamba iqhosha kwaye ulijikeleza kwinqanaba lewashi okanye i-push-clockwise motion, i-pin-pin ayihambeli, kodwa isalathisi isashintsha ii-angles.Iphepha liya kukhangela, kodwa i-pin fixed point of pin ayitshintshi. Oku kufana kakhulu nendlela umsebenzi ojikelezayo usebenza ngayo.
Shintsha i-Syntax
Ngokujikeleza, ubhala i-angle ye-turn and coordinates endaweni echanekileyo.
guqula = "ukujikeleza (45,100,100)"I-angle yokujikeleza yinto yokuqala oyongezayo. Kule khowudi, i-angle of rotation i-45 degrees. Ingongoma yedolophu yinto oyongeza ngayo. Apha, elo liziko lendawo lihleli kwiinqununu ezili-100, 100. Ukuba awuyi kungena kwii-coordinates zesikhundla, ziya kutshintsha ku-0,0. Kulo mzekelo ungezantsi, i-angle iya kuhlala ibe ngama-45 degrees, kodwa ukususela ekubeni ingongoma yeziko ayizange iqalwe, iya kutshintsha ku-0,0.
guqula = "ujikeleze (45)"Ngokungagqibekanga, i-angle iya ngakwesokunene kwicala legrafu. Ukujikeleza umlo kwindlela eyahlukileyo, usebenzisa uphawu lokunciphisa ukuluhlu lokubaluleka kwexabiso.
guqula = "ujikeleze (-45)"Ujikelezo lwe-45-degree lijikeleza ukusuka kwikota ekusekwe kwisangqa se-360-degree. Ukuba ubhala uluhlu lwe-revolution njengo-360, umfanekiso awuyi kutshintsha kuba uqobo uyayifaka kwisangqa esipheleleyo, ngoko umphumo wokugqibela uza kufana nokubonakala apho uqale khona.
