SVG kuya JPG Imibuzo Evame Ukubuzwa Yokuguqulwa

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

Layisha phezulu ihele lakho SVG futhi umguquli wethu ufaka ukulungisa umgangatho okwaziyo ifomethi ye-JPG. Kuzo zonke izimo ezingenalutho (PNG, TIFF, BMP) wonke ama-pixel agcinwa nge-bit-by-bit; kuzo zonke izimo ezingenalutho (JPG, WebP) ungalungisa i-quality factor (iphutha 90) ngaphambi kokufaka ngezansi. I-SVG igcina amafomu njengendlela ye-matematics nesihloko njengesihloko, hhayi njenge-pixels, ngakho-ke iyidokhumende kunaleyo ye-raster grid. I-JPG ilahlekelwa yisimo: isithombe siguqulwa nge-DCT, silinganiselwe, futhi sikhonjiswa nge-entropiya, nge-nobhu wobude olawula ukuthi yini elahlekile.

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

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 JPG 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-JPG iyisimo se-JPEG esijwayelekile kusukela ngo-1992, futhi ngemuva kweminyaka emithathu ihlala iyisimo esisetshenziswa amakhamera amaningi namanye amawebhusayithi asebenzisa ama-photos.

Ingabe ukubukhali kuzoqhubeka nokushintsha SVG kuya ku JPG?

Akuna - JPG ayikho i-alpha channel, ngakho amasifunda abonisa ngaphaya ahlanganisane nombala wesizinda, omhlophe uma ungashintsha. Lokhu kuyinto ejwayelekile kakhulu enjalo: ilogo ebukeka ihlanzekile kukhasi elimnyama lifika ngebhokisi elimhlophe libhekene nalo. Misela umbala omnyama ukuze ulinganise lapho isithombe sihlala khona, noma khetha okudingayo okugcina i-alpha. I-JPG ayinayo ukubukeka okucacile, ikhuphuka kancane ngaso sonke isikhathi lapho igcinwa kabusha, futhi ikhiqiza ukuvala okubonakalayo kumbala ophansi nombhalo oqinile.

Ingabe ngizolahlekelwa yikhwalithi eningi uma ngisuka ku SVG ngiye ku JPG?

Kukhwalithi engu-80-85 ushintsho alubonakali kude kakhulu kokubheka futhi ifayela liphansi ngo-60-80%. Ukwesaba ukuthi kuyindlela eyodwa: ukulondoloza kabusha i JPG phinda phinda ihlanganise ama-artefacts ngaso sonke isikhathi. Gcina i SVG njengenkosi futhi uphinde udale i JPG kusuka kuyo lapho ufuna ubukhulu obusha.

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 kushintsha umbhalo ube yi-pixels noma ube umbhalo wedokhumende ngokuya ngenjongo; ukuguqula ku-SVG kwenza kuphela umbhalo osemthethweni uma umsuka une-text layer ukuqala.

Ingabe ukuguqulwa SVG kuya ku JPG kugcina ukubukeka okucacile?

Ukubukeka okucacile kuhlala lapho JPG i-PNG, WebP, TIFF, GIF, noma i-SVG. Ukushintsha ibe yi-JPG kuzoba ne-alpha channel efana nendawo yangasemva ebomvu — uma ufuna ukubukeka okucacile, khetha okuzokwazi ukubukeka okucacile endaweni ye-JPG.

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

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

Yini ekwenzeke ku-EXIF metadata uma uguqula SVG usuka ku-JPG?

Ikhamera EXIF (ISO, ishutter, ilensi, GPS) igcinwa ngokuzenzakalela ngesikhathi SVG -> JPG lapho amafomethi amabili exhasa i-metadata. Sebenzisa ukushintsha ubumfihlo ukususa i-metadata ngaphambi kokulayisha ngezansi uma ufuna ukuhlanganisa izithombe ngaphandle kokutholakala kwendawo noma idivayisi-fingerprint.

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

Yebo — cindezela amafayela amaningi SVG endaweni yokulayisha futhi babeke ifile ngokufanayo. Isigaba esimahhala sithatha ama-100 MB ngefayela ngalinye; iPremium ayinaso isiphetho sefayela ngalinye futhi isebenza ngemisebenzi eminingi efana, ngakho-ke isithombe esingu-200 siqedela ngezansi kwemizuzu emibini.

Ingabe SVG kuya ku JPG 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 kubasebenzi bekhasimende.

Yini isixazululo kanye nezici zehele JPG?

Ukuziphatha okuzenzakalelayo yi-1:1 — i-JPG yakho yesokudla inezici ze-pixel ezifanayo ne-SVG. Uma ufuna ukushintsha ubukhulu njengengxenye yokuguqulwa, sebenzisa /resize-image/ ngemuva, noma ubeke izinhlelo nge- /image-pipeline/ utility.

Ingabe ihele JPG lincane uma kungabonakali izinto ezibonakalayo?

Nge-JPG / WebP, umgangatho 75-85 uvame ukuletha i-JPG 60-80% encane kune-SVG ngaphandle koshintsho olubonakalayo emgwaqweni wokubuka ojwayelekile. Nge-lossless JPG (PNG, TIFF), cabanga ukulondoloza okuncane — ngokuvamile 5-30% nge-deflate / LZW yokucindezela okungcono kune-source esenayo. I-JPG icindezela izithombe ezijwayelekile ngokuhle futhi ifundeka nganoma iyiphi idivayisi, isiphequluli nephrinta ekhona.

SVG

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

JPG

Amafayela we-JPG asebenzisa ukucindezeleka okulahlekile okuhlanganisiwe ngezithombe, kubonisa ubukhulu befayela elincane ngenkathi kugcinwa isilinganiso esibonakalayo.
