Indlela yokudala isithombe se-SVG esingakhula sewebhu

Uma usebenza ngezithombe zewebhu, ngokushesha noma kamuva kuzodingeka udale isithombe se-SVG esingandiswa. Kudingeka ibukeke iphelele kunoma yisiphi isikrini, ilayishe ngokushesha, futhi ingathinti kabi ukusebenza kwesayithi lakho. Ama-PNG noma ama-JPG ajwayelekile asebenza ezimweni eziningi, kodwa lapho ilogo yakho ibonakala ingacacile ku-TV ye-4K noma izithonjana zakho zilahlekelwa ukucaca kudivayisi entsha yeselula, yilapho uqaphela khona ukuthi udinga ngempela ihluzo ze-vector.

I-SVG (Scalable Vector Graphics) isibe yifomethi evelele yama-logo, izithonjana, imidwebo, ama-infographic, kanye nezithombe ezinyakazayo ezilula.Lena imibhalo ye-XML ehunyushwa futhi ihunyushwe yisiphequluli ngesikhathi sangempela, ukuze ilinganiswe ngaphandle kokulahlekelwa yikhwalithi, iguqulwe nge-CSS noma i-JavaScript, futhi ilungiselelwe i-SEO kanye nokufinyeleleka. Ake sibheke ngokucacile nangokufushane ukuthi ifomethi isebenza kanjani, ukuthi ungayidala kanjani kusukela ekuqaleni noma kusuka ku-JPG/PNG, ukuthi ungayihlanganisa kanjani kuwebhusayithi yakho, nokuthi ungayisebenzisa kanjani ngokugcwele.

Iyini ifayela le-SVG futhi kungani lingandiswa?

I-SVG imele i-Scalable Vector Graphics, okusho ihluzo ze-vector ezingalinganiswa ngaphandle kokulahlekelwa incazelo.Ngokungafani ne-JPG noma i-PNG, egcina ulwazi lwephikseli ngayinye, i-SVG igcina imiyalelo yokudweba—imigqa, amajika, imibala, kanye nezikhundla—ngendlela yekhodi ye-XML. Isiphequluli sifunda le miyalelo bese "sidweba kabusha" isithombe ngesisombululo esidingwa yidivayisi.

Le ndlela yokusebenza iqinisekisa ukuthi ifayela elifanayo le-SVG libukeka libukhali ngokulinganayo kufoni ephathekayo, kwimonitha ye-4K, noma ebhodini lokukhangisa.Awekho amaphikseli okufanele anwetshwe noma ahlanganiswe; okushintshaniswa usayizi yizimiso zezibalo ezichaza izimo. Ngaphezu kwalokho, njengoba kungumbhalo walo, ifayela lingavulwa futhi lihlelwe nganoma yimuphi umhleli wekhodi, ozenzakalelayo, ocindezelwe, futhi oguquliwe kusetshenziswa iJavaScript.

Ama-SVG awaxhomekile ekuxazululeni, alula kakhulu kwimidwebo elula, futhi ahambisana nazo zonke iziphequluli zesimanje.I-Chrome, i-Firefox, i-Safari, i-Edge, ne-Opera ziye zasekela le fomethi iminyaka eminingi. Ngisho ne-Internet Explorer 9 kanye nezinguqulo zakamuva zamukela i-SVG, yize kunemikhawulo ethile ezicini ezithuthukile kakhulu.

Noma kunjalo, ama-SVG awayona ikhambi lazo zonke izinhlobo zezithombe.Uma usebenzisana nezithombe eziyinkimbinkimbi, ngezigidi zemibala kanye nemininingwane eminingi, i-JPG ecindezelwe kahle ivame ukusebenza kahle kakhulu. Ukuzama ukwenza isithombe esiphelele sibe yi-vector ngokuvamile kudala ifayela elikhulu le-SVG, okunzima ukulilungisa futhi elingasebenzi kahle ekusetshenzisweni kwangempela.

I-Raster vs i-vector: umehluko phakathi kwe-SVG, i-JPG ne-PNG

Ukuze uqonde ukuthi kufanele nini ukudala isithombe se-SVG esingandiswa, udinga ukucaca ngomehluko phakathi kwezithombe ze-raster neze-vector.I-JPG, i-PNG, kanye ne-GIF ziyifomethi ye-bitmap: zigcina igridi yamaphikseli anemibala engaguquki. I-SVG, i-EPS, i-AI, noma PDF (engxenyeni yabo yevektha) chaza izinhlobo zezibalo.

Esithombeni se-raster, uma ukhulisa usayizi kakhulu, amaphikseli ayabonakala bese kuvela umphumela ojwayelekile "wezitebhisi".Lokho kulahlekelwa yikhwalithi akunakugwenywa uma uzama ukuphoqa isinqumo esingenaso isithombe sokuqala. Ngokuphambene nalokho, i-SVG ingandiswa ngendlela ofuna ngayo ngoba okukhuliswayo ifomula edweba umugqa ngamunye.

I-JPG ilungele izithombe ngoba icindezela kahle ukuhlukahluka kwemibala, okubangela ukulahlekelwa yikhwalithi ethile.Ngakolunye uhlangothi, i-PNG igcina ikhwalithi (ukucindezelwa okungenakulahlekelwa) futhi isekela ukucaca, okwenza ifaneleke kakhulu kwimidwebo enezizinda ezicacile, izithombe-skrini, noma izakhi zesixhumi esibonakalayo ezingadingi ukukalwa kakhulu.

I-SVG ikhanya kakhulu uma kukhulunywa ngezithonjana, amalogo, imifanekiso, imidwebo, amashadi, ama-infographic, kanye nezithombe ezilula.Kulolu hlobo lokuqukethwe, amafayela e-PNG avame ukuba makhulu, abukeke emabi kakhulu uma ekhulisiwe, futhi awakwazi ukuguqulwa ngendlela eguquguqukayo nge-CSS. Yingakho i-web ecosystem yamukele i-SVG yazo zonke izakhi zesikhombimsebenzisi sesimanje.

Ukusetshenziswa okuvamile kwezithombe ze-SVG ezingalinganiswa

Ekuklanyweni nasekuthuthukisweni kwewebhu, i-SVG isetshenziswa kakhulu ezintweni ezidinga ukugcina ubukhali obukhulu kunoma iyiphi idivayisi.Akuvamile ukuthi isayithi elilodwa lisebenzise amashumi noma amakhulu ama-SVG asatshalaliswe kumamenyu, izigaba, izinkinobho, izihloko, noma imifanekiso.

Izithonjana zingenye yezibonelo ezicacile lapho i-SVG ibusa khona.Izithonjana zemidiya yezenhlalo, amamenyu e-hamburger, izilinganiso zezinkanyezi, izithonjana zenqola yokuthenga… Zonke ziyazuza ekukhuleni kwefomethi. Ungasebenzisa isithonjana esifanayo ngosayizi omncane kumenyu yeselula kanye nosayizi omkhulu ekhasini lentengo ngaphandle kokulahlekelwa yinoma yimiphi imininingwane.

Ama-logo ezinkampani angenye indlela ebalulekile yokusetshenziswaUkulondoloza ilogo yakho njenge-SVG kuqinisekisa ukuthi izobukeka iphelele ku-favicon yakho, imenyu, isilayida sekhasi lasekhaya, nanoma yikuphi okuphrintiwe. Ngaphezu kwalokho, ifayela elilodwa lomthombo lingasetshenziswa kabusha kuwebhu, izethulo, amaphosta, namakhadi ebhizinisi ngaphandle kokulidala kabusha isikhathi ngasinye.

I-SVG isetshenziswa kakhulu kuma-infographic, ihluzo zedatha, kanye nemifanekiso eyenziwe ngokwezifiso.Ngenxa yokuthi okuqukethwe kusekelwe ku-vector, imigqa yezithombe ibukeka ihlanzekile, umbhalo ungagcinwa ucacile, futhi ifayela livumelana kalula namathebulethi, omakhalekhukhwini, kanye nezikrini ezinkulu.

Okokugcina, ama-SVG akuvumela ukuthi udale izithombe ezilula kakhulu nezithambile.Ungagqwayiza isithonjana esishintsha umbala uma uzulazula phezu kwaso, isilayishi esijikeleza ngokungenamkhawulo, noma ngisho nezithombe ezisabela ekuskroleni noma ekusebenzisaneni komsebenzisi usebenzisa i-CSS, i-SMIL, noma i-JavaScript.

Amathuluzi okudala isithombe se-SVG esingandiswa

Ukuze udale amafayela e-SVG, ungaqala kusukela ekuqaleni kumhleli we-vector noma uguqule izithombe ezikhona ngefomethi ye-raster noma ye-vector.Ukukhetha kuzoncika ekutheni ufuna umklamo omusha ngokuphelele noma ukuthi usuvele unelogo ngefomethi ye-JPG/PNG ofuna ukuyiguqula ibe yi-vector.

Izinhlelo ezivame kakhulu zokuklama nokuthumela i-SVG yi-Adobe Illustrator, i-Inkscape, i-CorelDRAW, i-Figma, kanye ne-SketchZonke zisebenza ngama-vector njengesisekelo futhi zikuvumela ukuthi ulondoloze ngefomethi ye-SVG enamazinga ahlukene okulawula usayizi, amafonti, kanye nohlobo lokuthumela ngaphandle. Uma ufuna izinketho ezengeziwe, bheka uhlu lwezinhlelo zokudala izithombe zama-vector.

I-Adobe Illustrator iyindinganiso yobungcweti ezinhlanganweni eziningi nasema-studio.Ikuvumela ukuthi udwebe ngethuluzi lePeni, uhlele umklamo ngezendlalelo, usebenzise imiphumela ethuthukisiwe, ukuthayipha kwekhwalithi ephezulu, bese uthumela ku-SVG, ulungise izinketho ezifana nokushumeka noma ukuxhumanisa amafonti, isitayela se-CSS sangaphakathi noma sangaphandle, kanye nezinga lokuhambisana.

I-Inkscape iyindlela ehlukile yamahhala nevulekile ehlanganisa cishe konke okudingwa ngumklami ojwayelekile.Inamathuluzi ezimo, ama-node, umbhalo, ama-gradients, izihlungi, kanye nokuthumela ngqo ku-SVG, okuyinto evame ukuyithola khiqiza ikhodi kuhlanzekile impela.

I-Figma ne-Sketch, ezidumile kakhulu ekwakhiweni kwesikhombimsebenzisi, zivumela futhi ukuthumela izithonjana nezingxenye njenge-SVG.Ziphelele uma usuvele usebenza ku-UI yakho kula mathuluzi ngoba ungathatha izithonjana zakho uziyise ngqo kukhodi ngaphandle kwezinyathelo eziphakathi.

Guqula izithombe ze-JPG noma ze-PNG zibe yi-SVG

Ngokuvamile awuqali kusukela ekuqaleni, kodwa usuvele unelogo noma umdwebo ngefomethi ye-JPG, i-PNG noma ye-PDF futhi udinga i-SVG ekwaziyo ukulinganiswa.Kulezi zimo kunezindlela ezimbili: ukwenza i-vector ngokuzenzakalelayo ngethuluzi lendlela noma ukudweba kabusha isithombe ngesandla ngethuluzi lePeni.

Amathuluzi okulandelela ngokuzenzakalelayo aguqula amaphikseli abe yizimo zevektha ngokushesha, kodwa ngemiphumela engaguquki.Kuma-logo alula, ngombala owodwa noma ngemininingwane embalwa, asebenza kahle kakhulu futhi akongela isikhathi. Nokho, kuma-graphics ayinkimbinkimbi, akhiqiza izinkulungwane zama-node kanye nefayela le-SVG elikhulu kakhulu, okunzima ukulihlela. Uma udinga ukujula ezindleleni ezenziwe ngesandla, hlola amasu okulandelela kanye nokufaka i-vector ku-Illustrator.

Amanye amapulatifomu akhethekile anikeza izinsizakalo zokwenziwa kwe-vector ngesandlaNgalezi zinsizakalo, ulayisha ilogo yakho ngefomethi ye-JPG, PNG, noma ye-PDF, bese umklami eyidweba kabusha ngesandla ku-Illustrator esebenzisa amafonti afanele, eletha ifayela le-EPS/AI/SVG elihlanzekile elilungele ukuphrinta noma iwebhu. Kuyindlela ethembeke kakhulu yama-logo omkhiqizo okudingeka abukeke ephelele.

Uma uguqula kusuka kwezinye izinhlobo ze-vector njenge-EPS noma i-AI, abaguquli be-SVG bavame ukugcina cishe lonke ulwazi.Kulesi simo, umbala, izimo, kanye nesakhiwo sesendlalelo kugcinwa ngokwethembeka, inqobo nje uma ungasebenzisi imiphumela eqondile kakhulu evela kuhlelo oluthile.

Uma umthombo kuyisithombe noma isithombe se-raster esiyinkimbinkimbi kakhulu, i-vectorization ezenzakalelayo ayinikezi umphumela owusizo.Kulesi simo, into enengqondo kakhulu ongayenza ukugcina isithombe sisefomethini ye-JPG noma ye-WebP bese ubhuka i-SVG yezithonjana, ozimele, umbhalo, noma izakhi zesithombe ezimboziwe.

Indlela yokudala ifayela le-SVG isinyathelo ngesinyathelo

Uma ufuna ukuklama isithombe sakho se-SVG esingakhula kusukela ekuqaleni, indlela yokusebenza eyisisekelo ifana kakhulu cishe kubo bonke abahleli be-vector.Nasi isifinyezo esijwayelekile ukuze ukwazi ukusisebenzisa ku-Inkscape, Illustrator, noma amathuluzi afanayo.

Isinyathelo sokuqala ukudala i-canvas noma indawo yokusebenza enobukhulu obufaneleNakuba i-SVG izokwelulwa kamuva, kuyalulekwa ukusebenza "ngosayizi babantu" (isibonelo, ama-px angu-500×500 ngesithonjana noma ama-px angu-1200×600 ngesihloko), ngoba lokho kwenza umklamo ube ntofontofo futhi kusiza ukugcina izilinganiso.

Okulandelayo kuza isigaba sokudwebaSebenzisa ithuluzi le-Pen noma le-Bezier ukudweba izinhlaka, imigqa, nama-curve, kanye namathuluzi ayisisekelo okuma (ama-rectangles, ama-ellipses, ama-polygon) ukwakha umklamo wakho. Ukuma ngakunye kuzorekhodwa njengendlela noma isethi yezindlela ku-SVG XML.

Kulezi zindlela ufaka imibala yokugcwalisa nokushaya, ubukhulu bemigqa, amakhona ayindilinga, ama-gradients, noma amaphethiniZonke lezi zimfanelo zingahunyushwa zibe yi-CSS, ngakho-ke kuyalulekwa ukuthi ungasebenzisi ngokweqile imiphumela engavamile engahumushi kahle kusiphequluli.

Uma umklamo wakho usulungile, lungisa ibhodi lobuciko ukuze livumelane nokuqukethwe.Ezinhlelweni eziningi kunenketho yokufaka i-canvas emikhawulweni yomdwebo futhi ugweme imingcele engenalutho; lokhu kusiza ukuqinisekisa ukuthi i-SVG ayinaso isikhala esimhlophe esingadingekile esiyizungezile.

Ekugcineni, thumela noma ulondoloze njenge-SVGIbhokisi lengxoxo yokuthumela livame ukufaka izinketho zokwenza lula izindlela, kufaka phakathi izitayela njengezimfanelo eziku-inline noma njenge-CSS, izithombe ezifakiwe noma amafonti, njll. Ekusetshenzisweni kwewebhu, i-SVG ehlanzekile nelula kakhulu ngangokunokwenzeka, ngaphandle kwe-metadata engadingekile, ngokuvamile iyafiseleka.

Shintsha usayizi bese ukala i-SVG ngaphandle kokulahlekelwa ikhwalithi

Into enhle ngefomethi ukuthi ungakhulisa usayizi we-SVG ngaphandle kokuthi iguqulwe ibe yi-pixel, kodwa lokho akusho ukuthi akufanele unake ukuthi ikhula kanjani.Isici esiyinhloko kule nqubo yi- bukaBox, okuchaza uhlelo lwangaphakathi lokuhlanganisa lwegrafu.

Kufayela le-SVG uqobo uzobona into efana ne-viewBox="0 0 100 100"Lokhu kusho ukuthi wonke umdwebo uklanywe ngaphakathi kwesikwele samayunithi angu-100x100. Uma utshela isiphequluli ku-HTML ukuthi i-SVG kufanele ibe ububanzi obungu-200px, isiphequluli simane siphindaphinde lawo mayunithi ukuze avumelane nokuqukethwe.

Ukuze i-SVG iphendule ngempela, kuyinto evamile ukususa izimfanelo zobubanzi nokuphakama ku-element. bese ushiya i-viewBox kuphela. Bese, ku-CSS, ukuziphatha kwayo kulawulwa ngento elula njengokuthi:

svg { ukubonisa: i-inline-block; ububanzi obukhulu: 100%; ukuphakama: self; }

Uma udinga ukukhulisa ama-SVG amaningi ngobuningi futhi ungafuni ukuthinta ikhodi, kunezindlela eziku-inthanethi ezisebenza njengamathuluzi "okushintsha usayizi" wama-SVG.Lezi zinsiza zikuvumela ukuthi uchaze usayizi omusha ngamaphesenti noma amayunithi, usebenzise ukuguqulwa, futhi ulande inguqulo entsha elinganisiwe, ngaphandle kwesidingo sokufaka noma iyiphi isofthiwe.

Indlela yokufaka i-SVG ekhasini lewebhu

Uma usunesithombe sakho se-SVG esingandiswa, isinyathelo esilandelayo ukusifaka kusiphequluli.Kunezindlela eziningana zokwenza lokhu, futhi ngayinye ikunikeza izinga elihlukile lokulawula izitayela, ukufinyeleleka, kanye nokusebenza.

Indlela eyisisekelo neqondile kakhulu ukusebenzisa ilebula ekhomba ifayela le-SVG langaphandle. Ngokwesibonelo: Kuyindlela efanayo neye-JPG, yisiphequluli kuphela esaziyo ukuthi insiza isekelwe ku-vector.

Uma ufuna ukulawula okwengeziwe, ungashumeka ikhodi ye-SVG ngokwayo ngaphakathi kwe-HTML usebenzisa ithegiUma kunjalo, ukopisha okuqukethwe kwefayela bese ukunamathisela kukhodi yekhasi lakho. Lokhu kukuvumela ukuthi ushintshe imibala nge-CSS, wengeze amakilasi, uguqule izingxenye ezithile nge-JavaScript, futhi uthuthukise ukufinyeleleka.

Enye indlela, engasetshenziswa kakhulu namuhla kodwa esasebenza, ukusebenzisa noma yikuphi ukulayisha i-SVG njengomthombo wangaphandle oshumekiweInemikhawulo ethile ngokwesitayela kanye nokufinyeleleka, ngakho empeleni cishe wonke umuntu uyathanda noma i-SVG emugqeni.

Izinhlelo zokuphatha okuqukethwe njenge-WordPress azivumeli ukulayishwa kwe-SVG ngokuzenzakalelayo ngezizathu zokuphepha.Kulula ukuzivumela ngokufaka ama-plugin afana ne-Safe SVG noma i-SVG Support, ahlanza ifayela ukuze alivimbele ukuthi liqukethe izikripthi ezinonya futhi akuvumele ukuthi uwasebenzise kusuka kulabhulali yemidiya njenganoma yisiphi esinye isithombe.

Yenza isitayela futhi uphile i-SVG nge-CSS nekhodi

Enye yezinzuzo ezinamandla kakhulu zokuba nesithombe se-SVG esingandiswa ukuthi singaphathwa njengokungathi siyingxenye ye-DOM yekhasi uqobo.Lokhu kusho ukuthi singasebenzisa izitayela nge-CSS futhi sakhe ama-animation nge-CSS, i-SMIL, noma i-JavaScript ngaphandle kokuthinta ifayela eliyisisekelo.

Uma ushumeka i-SVG emugqeni (akufani ne- (kwangaphandle), ungashintsha umbala wokugcwalisa bese ushaya ngqo nge-CSSIsibonelo: svg path { fill: red; stroke: blue; }. Lokhu kuvumela, isibonelo, ukusebenzisa kabusha ifayela elifanayo ukubonisa ilogo ngombala owodwa kusihloko kanye nombala ohlukile ku-footer.

Isici sokugcwalisa sichaza umbala wendawo yangaphakathi yesimo, kanti isigqi silawula umbala kanye nobukhulu bohlaka.Ungashintsha futhi izakhiwo ezifana nobubanzi be-stroke, i-stroke-dasharray, noma i-stroke-linecap ukuze ufeze imiphumela edwetshwe ngesandla noma imigqa enamachashazi.

Ukuze uthole izithombe ezilula, i-CSS yanele.Ungenza isithonjana sishintshe umbala uma uzulazula phezu kwaso, ujikeleza, ushaya i-pulse, noma uskrola usebenzisa ukuguqulwa okujwayelekile kanye nokuguquka.

Uma udinga okuthile okuyinkimbinkimbi, indinganiso ye-SVG ngokwayo ifaka izinto ezifana ezivumela izimfanelo zokugqwayiza ku el tiempoIsibonelo, ukwenza indilinga isuke kolunye uhlangothi iye kolunye, ishintsha isikhundla sayo cx imizuzwana emihlanu, ngendlela ejikelezayo, ngaphandle kwesidingo sezikripthi zangaphandle.

Ukuze uthole izithombe eziyinkimbinkimbi nezisebenzisanayo, i-JavaScript (noma imitapo yolwazi ethile) ikuvumela ukuthi uxhume i-SVG nemicimbi yomsebenzisiUngahambisa izingxenye zeshadi ngokuchofoza, ukuvumelanisa izithombe ezinyakazayo ngokuskrola, noma ukushintsha ukubukeka ngokusekelwe kudatha ikhasi eliyitholayo, okuvulela umnyango wokuboniswa kwedatha okucebile kakhulu.

Ama-sprites e-SVG kanye nokwenza ngcono ukusebenza

Uma iwebhusayithi isebenzisa amashumi noma amakhulu ezithonjana, ukulayisha i-SVG ngayinye ngokwehlukana kuhilela izicelo eziningi ze-HTTP.Ukuze unciphise lelo nani futhi usheshise ukulayisha, kuyasiza kakhulu ukusebenzisa ama-sprites e-SVG noma amasu afanayo okuqoqa.

I-SVG sprite ngokuyisisekelo ifayela elikhulu eliqukethe izithonjana eziningi ezichazwe ngaphakathi kwezintoBese, engxenyeni ngayinye ye-HTML yakho lapho ufuna ukubonisa khona isithonjana, usebenzisa Ngale ndlela, isiphequluli silanda i-sprite kanye kuphela bese siphinda sisebenzise izithonjana ngaphakathi.

Le ndlela inciphisa kakhulu inani lezicelo eziya kuseva.Lokhu kunciphisa ukubambezeleka futhi kuthuthukisa ulwazi lomsebenzisi, ikakhulukazi ekuxhumaneni kweselula. Ngaphezu kwalokho, usakwazi ukushintsha imibala nosayizi usebenzisa i-CSS.

Ngaphandle kwe-sprites, kunezindlela ezithile zokucindezela nokwenza ngcono i-SVG.Izinsiza ezifana ne-SVGO noma inguqulo yayo yewebhu i-SVGOMG zihlaziya ikhodi, zisuse imethadatha, izikhala, izimfanelo ezingadingekile, amaphuzu angafuneki ezindleleni nakho konke okungathinti umphumela obonakalayo.

Abahleli abaningi be-vector bafaka nezici zokunciphisa indlela ezakhelwe ngaphakathiUkunciphisa inani lama-node kuma-curve ayinkimbinkimbi akugcini nje ngokunciphisa usayizi wefayela, kodwa futhi kwenza kube lula ukuhlela okulandelayo futhi kuvimbele isiphequluli ekubeni sibale izindlela eziyinkimbinkimbi kakhulu.

Emakhasini anezithombe eziningi ngaphansi kwesithombe, kungumqondo omuhle ukuhlanganisa i-SVG namasu okulayisha avilaphayo.Nakuba ama-SVG ngokuvamile elula, akunangqondo ukulayisha zonke izithonjana nemifanekiso ngesikhathi esisodwa umsebenzisi angeke akubone aze askrole amaphikseli angamakhulu amaningana.

Ukuhambisana, i-SEO, kanye nokufinyeleleka ku-SVG

Ngokuhambisana, isimo samanje silula kakhulu: zonke iziphequluli zesimanje zisekela kakhulu i-SVG.I-Chrome, i-Firefox, i-Safari, i-Edge, ne-Opera zibonisa ihluzo ze-SVG kalula kudeskithophu nakuselula, futhi ukungena kweziphequluli ezindala ngempela sekuphansi kakhulu kumaphrojekthi amaningi.

Isici sangempela sokuhlukanisa i-SVG uma iqhathaniswa ne-JPG noma i-PNG ukuthi okuqukethwe kwayo kungumbhalo futhi, ngakho-ke, kuyafundeka yizinjini zokusesha kanye nobuchwepheshe bokusiza.Lokhu kuyenza ibe umngane othakazelisayo we-SEO kanye nokufinyeleleka, uma kusetshenziswa amathegi nezimfanelo ezifanele.

Ngaphakathi kwento ethile ungafaka kanye <desc> ukuchaza igrafuLawa ma-node asetshenziswa njengolwazi olufinyeleleka kalula kubafundi besikrini futhi ahlinzeka nangomongo we-semantic kokuqukethwe kwefayela, okwenza kube lula ukuqopha.

Isici role="img" sitshela ubuchwepheshe bokusiza ukuthi i-SVG isebenza njengesithombe, kanye ne-aria-labelledby ingaxhumanisa i-SVG nokuqukethwe kwe- kanye ne-<desc>. Ezimweni eziyinkimbinkimbi, kusanconywa ukuthi uhambisane nesithombe nombhalo ohlukile ku-HTML noma usebenzise i-alt ku-<img> uma uyifaka njengomthombo wangaphandle.

Ngokombono wokusebenza kokusesha, ukusebenzisa ama-SVG alungiselelwe kunciphisa isisindo sekhasi lilonke.Ama-kilobyte ambalwa asho izikhathi zokulayisha eziphansi, okuthonya kahle izilinganiso ezifana ne-LCP noma i-FCP. -Google Kucatshangelwa ngaphakathi kwe-Core Web Vitals.

Kumaphrojekthi lapho kusenabasebenzisi abaneziphequluli ezindala kakhulu, izixazululo zokubuyela emuva zingasetshenziswa.Isibonelo, ukukhonza i-PNG efanayo usebenzisa noma izimo ezithile. Kodwa-ke, empeleni, lezi zixazululo azidingeki kakhulu.

Izindlela ezinhle kakhulu zokuklama nokuphatha amafayela e-SVG

Ukudala isithombe se-SVG esingandiswa akukhona nje "ukuthumela ku-SVG," kuhilela nomkhakha othile wokuklama nokubhala amakhodi.Uma uqaphela indlela oqamba ngayo izendlalelo, wenze lula izindlela, futhi uhlele ifayela, kuzoba lula ukuligcina futhi kube ngcono ekukhiqizeni.

Kunconywa ukugcina i-SVG icocekile, ine-indentation ehambisanayo kanye namagama e-ID anencazelo kanye namagama ekilasi.Isibonelo, ukusebenzisa i-id="cart-icon" kuwusizo kakhulu kune-id="path123" uma udinga ukusebenzisa izitayela ezithile ezivela ku-CSS noma ukuguqula isici nge-JavaScript.

Ukunciphisa izinto ezifihliwe, izendlalelo ezingafuneki, kanye nezimfanelo eziphindaphindwayo kungenye into ebalulekile.Amafayela amaningi akhiqizwe ngqo kusuka kuhlelo lokuklama aphethe ulwazi olungenamsebenzi ku-inthanethi futhi olungahlanzwa ngokuphephile nge-SVGO noma okufanayo.

Uma usebenza nama-SVG amaningi kuphrojekthi, kungumqondo omuhle ukuwahlela abe amafolda anengqondo anamagama wamafayela ahambisanayo.Ukuba ne-/svg/icons/, /svg/logos/ kanye ne-/svg/illustrations/ kuzokongela isikhathi lapho uthola izinsiza futhi kuzokwenza kube lula ukwenza izinqubo zokwenza ngcono zibe ngokuzenzakalela.
