SVG kuya PNG Imibuzo Evame Ukubuzwa Yokuguqulwa

Ngiguqula kanjani i-SVG ibe yi-PNG ngaphandle kokulahlekelwa ubuhle besithombe?

Layisha phezulu ihele lakho SVG, bese isiguquli sethu sifaka ukulungisa umgangatho okwaziyo ifomethi ye-PNG. Ifomethi engalahleki (PNG, TIFF, BMP) sigcina wonke ama-pixel; ifomethi elahlekile (JPG, WebP) ungahlela umphumela womgangatho ngaphambi kokufaka.

Yini isixazululo okufanele ngiyi-rasterize ku SVG uma ngiguqula ku PNG?

Khetha ubukhulu obukhulu obungabonisa khona, ngoba lokhu kuyingxenye lapho ifayela liyeka khona ukubukeka kwe-independent. A SVG igcinwa njengendlela ye-mathematics futhi ibonisa ngokucacile nganoma yisiphi isilinganiselo; i PNG iyi-pixel grid eqinile, futhi ukuwukhulula ngemuva kungafaka kuphela. Rhweba ngaphandle ngokuphindaphindiwe kwesayizi elindelekile yokukhombisa uma ibhekisa kwi-high-DPI screen. I-SVG ibonisa kahle nganoma yisiphi isibalo, ihlala ihleliwe, itholakale futhi ihlukaniswe njengetekisi elijwayelekile, futhi ivame ukuba yingxenye yesimo se-PNG. I-PNG yakhiwa ngo-1996 njengento eshintshayo engekho emthethweni ye-GIF, futhi yashintsha ibe yifomethi yesithombe esingasebenzisi iphutha ye-web.

Ubhalo ngaphakathi kwe-SVG usebenza kanjani?

Ku-SVG, umbhalo ubhalwe ngokusemthethweni - ukhethwa, utholakale futhi uphinde ushintshwe, futhi kudinga ukuthi umbhalo ubekhona noma ufakwe ukuze usebenze ngendlela efanele. Ukushintsha kusuka ku-SVG kuguqula lo mbhalo ube yi-pixels noma ube umbhalo wedokhumende ngokuya ngenjongo; ukuguqula ku-SVG kukhiqiza umbhalo osemthethweni kuphela uma umsuka une-text layer ukuqala.

Ingabe kukhona okulahlekile ekushintsheni phakathi kwe SVG ne PNG?

Akukho data ye-pixel, cha. Ifomethi zombili zigcina isithombe ngaphandle kokucindezeleka okulahlekile, ngakho isithombe esiphumayo sifana nesinye esingene ngaphakathi futhi ukuguqulwa kungaphinda kwenziwe ngaphandle kweso. Okunye okushintshayo yisayizi yefayela, futhi okunye okuphawulekayo ukushayela — ububanzi bombala, amaprofayili afakwe, ama-layers kanye nobuciko bonke baxhaswa ngokuhlukile phakathi kwefomethi engalahleki. I-SVG igcina amafomu njengendlela ye-matematics nesihloko njengesihloko, hhayi njenge-pixels, ngakho-ke iyidokhumende kunaleyo ye-raster grid. I-PNG isebenzisa ukucindezelwa kwe-DEFLATE phezu kwemigqa yokuskena ehlolwe, ngakho wonke ama-pixel ahlala ngokugcwele, kanye ne-8-bit alfa channel ephelele.

Ingabe ukuguqulwa SVG kuya ku PNG kugcina ukubukeka okucacile?

Ukubukeka okucacile kuhlala lapho uhamba ku-PNG, WebP, TIFF, GIF, noma SVG. Ukushintsha ku-JPG kuhlanganiswa isixhumi se-alpha esibhekene nesizinda esimhlophe — uma ufuna ukubukeka okucacile, bheka ifomu elikwaziyo ukubukeka okucacile endaweni ye-PNG.

Ingabe iprofayili yami yombala (sRGB / Adobe RGB / CMYK) izohlala i SVG kuya ku PNG?

Amaprofayili wemibala we-ICC afakwe ngaphakathi afundwa kusuka kumthombo SVG futhi axhunywe kabusha ku-PNG lapho ifomethi ixhasa khona (JPG, PNG, TIFF, WebP). Amafomethi enza i-profayili ayixhasi ibuyela emuva ku-sRGB.

Yini mayelana ne-EXIF metadata uma uguqula SVG usuka ku-PNG?

Ikhamera EXIF (ISO, ishutter, ilensi, GPS) igcinwa ngokuzenzakalela ngesikhathi sokuguqulwa SVG → PNG lapho amafomethi amabili exhasa i-metadata. Sebenzisa ukhetho lokufihla ukususa i-metadata ngaphambi kokulayisha ngezansi uma ufuna ukuhlanganisa izithombe ngaphandle kokutholakala kwe-geolocation.

Ingabe ngingenza ukuguqulwa kwekhulu le SVG amafayela ku PNG ngasikhathi sinye?

Yebo — cindezela amafayela amaningi SVG endaweni yokulayisha futhi sizowabeka emqoka ngokufanayo. Abasebenzisi abamahhala bathola ama-100MB ngefayela ngalinye; iPremium ayinaso isiphetho sefayela ngalinye futhi isebenza nabasebenza ngokufanayo, ngakho-ke isithombe esingu-200 siqediwe ngaphantsi kwemizuzu emibini.

Ingabe SVG kuya ku PNG iqhathaniswa kanjani ne-Photoshop / GIMP ngemisebenzi efanayo?

Ukuguqulwa kwefomethi elula sisebenzisa i-libpng / libjpeg-turbo / libwebp / ImageMagick pipes efana ne-desktop editor esebenzisa, ngekhwalithi efanayo. Ushintsho ukuthi amathuluzi wedesktop avula ifayela elinye ngasikhathi sinye; sivumela iqembu futhi sisebenzisana nabo.

Yini isixazululo kanye nezici zehele lami PNG?

Ukuziphatha okuzenzakalelayo yi-1:1 — i-PNG yakho yesokudla inezici ze-pixel ezifanayo ne-SVG. Sebenzisa isikhashana /ukuguqula-isifanekiso/ esisodwa ngemuva kokuguqulwa uma ufuna ukuncipha noma ukuphakama njengengxenye yokuhamba komsebenzi.

Ingabe ihele PNG lincane uma kungabonakali izinto ezibonakalayo?

I-JPG / WebP, ikhwalithi engu-75-85 ithola ihele elincincane ngama-60-80% kunalomthombo SVG ngaphandle koshintsho olubonakalayo emgwaqweni wokubuka ojwayelekile. Inhloso engalahleki (PNG, TIFF), cabanga ukulondoloza okuncane — ngokuvamile 5-30% nge-deflate / LZW yokucindezela okungcono.

Ingabe amafayela ami SVG afihlakele ngesikhathi sokuguqulwa?

Yebo — amafayela alayishwe phezulu SVG aphathwa ngabasebenzi abahlukanisiwe futhi asuswa ngaphakathi kwemizuzu. Asikwazi ukufunda, ukugcina, noma ukuhlanganisa idatha ye-pixel. Inqubomgomo yobumfihlo obuphelele kanye nefasitela lokugcinwa kubhalwe ku /privacy/.

SVG

Amafayela e-SVG aqukethe ihluzo zevektha ezikhula kahle kunoma yimuphi usayizi ngaphandle kokulahlekelwa ikhwalithi.

PNG

Amafayela e-PNG asekela ukucaca futhi asebenzisa ukucindezela okungenakulahlekelwa, okwenza afaneleke kakhulu kuma-graphics, ama-logo, kanye nezithombe-skrini.
