Izinzuzo ze-SVG
Njengoba usakha iwebhusayithi futhi ungeze izithombe kuleso sitesithi, eyodwa uma izinto ezibaluleke kakhulu okumele ukhethe ukuthi yiziphi amafomethi wefayela ezifanele ukuzisebenzisa. Kuye ngokucacile, ifomethi eyodwa ingase ibe ngcono kangcono kunabanye.
Abakhiqizi bewebhu abaningi banenhlanhla ngefomethi yefayili yeJPG, futhi le fomethi iphelele izithombe ezinokujula kombala ojulile, njengezithombe. Ngenkathi le fomathi izophinde isebenze ihluzo ezilula, njengezithombe ezifanekisiwe, akuyona indlela engcono kakhulu yokusebenzisa kuleso simo. Kulezo zithombe, i-SVG kuyoba yisinqumo esingcono. Ake sibheke ukuthi kungani:
I-SVG iVector Technology
Lokhu kusho ukuthi akuwona ubuchwepheshe be-raster. Izithombe ze-Vector ziyinhlanganisela yemigqa eyenziwe besebenzisa izibalo. Amafayela ama-Raster asebenzisa amaphikseli noma izikwele ezincane zombala. Lesi yisinye sezizathu ukuthi i-SVG ihlasele futhi iphelele kumawebhusayithi aphendulayo okufanele ahambisane nesayizi yesikrini sedivayisi. Ngenxa yokuthi ihluzo ze-vector zikhona ezweni lemathematics, ukushintsha usayizi, uvele ushintshe izinombolo. Amafayili ama-Raster ngokuvamile adinga ukukhokhiswa okuphawulekayo uma kuziwa ekuqaliseni. Uma ufuna ukusondeza esithombeni se-vector, akukho ukuphazamiseka ngoba uhlelo luyimathemathiki futhi isiphequluli sisho kabusha izibalo futhi senze imigqa ibusheleleke kunanini ngaphambili. Uma usondeza esithombeni se-raster, ulahlekelwa ikhwalithi yesithombe futhi ifayela liqala ukungenaziqalo njengoba uqala ukubona lawo maphikseli ombala. Izibalo ziyakhula futhi izivumelwano, amaphikseli akwenzi. Uma ufuna izithombe zakho zibe yisinqumo esizimele, i-SVG izokunika lelo khono.
I-SVG i-Text-Based
Uma usebenzisa umhleli wehluzo ukukhiqiza isithombe, uhlelo luthatha isithombe sezithombe zakho eziphelile. I-SVG isebenza ngokuhlukile. Usengasebenzisa izinhlelo ezithile ze-software futhi uzizwe sengathi udweba isithombe, kodwa umkhiqizo wokugcina iqoqo lamigqa ye-vector noma ngisho namagama (okuyiwona kuphela ama-vectors onb ekhasini). Izinjini zibheka amagama, ikakhulukazi amagama angukhiye. Uma ulayisha i- JPG , uyanqanda isihloko se-graphic yakho futhi mhlawumbe inkulumo ye- alt . Nge-coding ye-SVG, ukwandisa ngamathuba futhi udale izithombe ezingaphezulu kwe-search-engine friendly.
I-SVG Ingabe i-XML neyasebenza ngaphakathi kwezinye izilimi zolimi
Lokhu kubuyela ekhelini elisekelwe ematheksthini. Ungenza isithombe sakho sisekelo ku-SVG futhi usebenzise i- CSS ukuze uyiphenye. Yebo, ungaba nesithombe esivela kuyifayela le-SVG, kodwa futhi ungayikhokha ngqo i-SVG ekhasini bese ulihlela esikhathini esizayo. Ungayishintsha nge-CSS ngendlela efanayo ongayishintsha ngayo umbhalo wekhasi, njll. Lokhu kunamandla futhi kwenza kube lula ukuhlela.
I-SVG ihlelwe kalula
Lokhu cishe kunenzuzo enkulu kakhulu. Uma uthatha isithombe sikwele, yilokho okuyikho. Ukuze wenze ushintsho, kufanele uphinde usethe indawo futhi uthathe isithombe esisha. Ngaphambi kokuthi wazi, unemifanekiso engu-40 yezikwele kanti namanje awunawo kahle. Nge-SVG, uma wenza iphutha, shintsha izixhumanisi noma igama kumhleli wombhalo, futhi usuqedile. Ngiyakwazi ukuqonda lokhu ngoba ngidonsele umbuthano we- SVG owawusekho kahle. Konke okwakudingeka ngikwenze kwakulungisa izixhumanisi.
Izithombe ze-JPG zingaba nzima
Uma ufuna isithombe sakho sikhule ngobukhulu obungokwenyama, sizophinde sikhule usayizi wefayela. Nge-SVG, i-pounds isengamakhilogremu kungakhathaliseki ukuthi ukhulu kangakanani. Isikwele esingamasentimitha amabili ububanzi sizoba nesisindo esifanayo nesikwele esingamamitha angu-100 ububanzi. Usayizi wefayela awushintshi, okuhle kakhulu ekuboneni kwekhasi lokusebenza!
Yikuphi Okungcono?
Ngakho iyini ifomethi engcono - i-SVG noma i-JPG? Lokho kuxhomeke esithombeni ngokwayo. Lokhu kufana nokubuza ukuthi "yini engcono, isando noma isikulufuzi?" Kuncike kulokho okudingayo ukufeza! Kuyafana nalezi zakhiwo zesithombe. Uma udinga ukubonisa isithombe, i-JPG iyona engcono kakhulu kuwe. Uma ungeza isithonjana, kungenzeka ukuthi i-SVG ingcono kakhulu. Ungafunda kabanzi mayelana nokuthi kufanelekile ukusebenzisa amafayela we-SVG lapha .
