SVG ukuba PNG Imibuzo Ebuzwa Rhoqo Ngokuguqula

Ndiyiguqula njani i-SVG ibe yi-PNG ngaphandle kokulahlekelwa umgangatho womfanekiso?

Layisha phezulu ifayile yakho SVG kwaye umguquli usebenzise umgangatho owaziyo wefomati efanelekileyo ye PNG. Ukungabikho kolahleko PNG (PNG, TIFF, BMP) yonke ipixel igcinwa; ukungabikho kolahleko PNG (JPG, WebP) ungalungisa umgangatho womsebenzi phambi kokukhuphela. I-SVG igcina iimpawu njengendlela ye-matematics nombhalo njengombhalo, hayi njenge-pixels, ngoko ke luxwebhu kunokuba luyi-raster grid. I-PNG isebenzisa uxinzelelo lwe-DEFLATE ngaphezulu kwamagqabantshintshi okuskena acociweyo, ngoko ke i-pixel nganye ihlala ngokuchanekileyo, kunye ne-8-bit epheleleyo ye-alpha channel.

Yintoni isisombululo kufuneka ndiyi-rasterize i SVG xa ndiguqula kwi PNG?

Khetha ubungakanani obukhulu obungabonisi kuyo, kuba le yinyathelo apho ifayile iqala ukuba i-resoluble-independent. A SVG igcinwa njengendlela ye-mathematics kwaye ibonisa ngokucacileyo nakweyiphi na ubungakanani; i PNG yi-pixel ethe nkqo yothungelwano, kwaye ukongeza emva koko ungasebenzisa kuphela uxinzelelo. Rhweba ngaphandle kwisibini sobungakanani bokubonisa olungenayo ukuba ikhokelela kwi-DPI ephezulu yekhusi. I-SVG ibonisa kakuhle nakweyiphi na ubungakanani, ihlala ihlela, ikhangela kwaye iguqula njengombhalo ocacileyo, kwaye ihlala ilingana nobungakanani be-PNG. I-PNG yaphuhliswa ngowe-1996 njengento engekhoyo kwipateni ye-GIF, kwaye yayiyifomati yomfanekiso ongekhoyo kwi-web.

Ukuziphatha kombhalo ngaphakathi kwe-SVG kunjani?

Kwi-SVG, umbhalo ngumbhalo okweli hlabathi - okhethwayo, okhangelayo nophinda-uhlobo, kwaye ufuna ifonti ukuba ikhona okanye ifakwe ukuze ibonise njengoko kumiselwe. Ukutshintsha ukusuka kwi-SVG kuguqula umbhalo ube yi-pixels okanye ube ngumbhalo woxwebhu ngokuxhomekeke kwinjongo; ukuguqula ukuya kwi-SVG kuguqula kuphela umbhalo ovela kweli hlabathi ukuba umbhali wayene-maleko yombhalo wokuqalisa.

Ingaba kukho into elahlekile ekuguquleni phakathi kwe SVG ne PNG?

Akukho data yepixel, hayi. Zonke iifomati zigcina umfanekiso ngaphandle koxinzelelo olulahlekileyo, ngoko ke umfanekiso ophumayo ufana nowo waya ngaphakathi kwaye uguqulelo luyaphinda uphinde luphinde. Okutshintshayo kubungakanani befayili, kwaye oku kusebenza ukuhamba - ubunzulu bombala, iiprofayili ezifakelweyo, amanqanaba noopopayi bonke baxhaswa ngokungalinganiyo phakathi kwefomati ezingalahlekileyo.

Ingaba uguqulelo SVG ukuya PNG lugcina ukubonakala?

Ukubonakala ngaphaya kuqhubeka xa PNG i-PNG, WebP, TIFF, GIF, okanye SVG. Ukutshintsha kwi-JPG kugubungela isiqhagamshelanisi se-alpha phantsi kokungasemva omhlophe. Ukuba ufuna ukubonakala ngaphaya kwiziphumo, cwangcisa ukubonakala ngaphaya okuziyo PNG endaweni ye-PNG=JPG.

Ingaba iprofayili yam yombala (sRGB / Adobe RGB / CMYK) izakuhlala i SVG ukuya ku PNG?

Iiprofayili zombala we-ICC ezifakwe ngaphakathi zifundwa ukusuka kwi SVG kwaye zidityaniswe kwakhona kwi-PNG apho ifomati ixhasa khona (JPG, PNG, TIFF, WebP). Iifomati ezingaxhaswanga zibuyela kwi-sRGB, egcina imibala ihambelana nakwimboniselo eninzi yexesha elidlulileyo.

Yintoni malunga ne-EXIF metadata xa uguqula SVG ukuya PNG?

I-EXIF yekhamera (ISO, i-shutter, i-lens, i-GPS coords) igcinwa ngokumiselweyo ngexesha SVG → PNG xa zombini iifayili zixhasa i-metadata. Sebenzisa ukhetho lobumfihlo ukususa i-metadata phambi kokukhuphela ukuba ufuna ukuthumela imifanekiso ngaphandle kolwazi lwendawo.

Ndingaguqula iifayili ezininzi SVG zibe PNG ngaxeshanye?

Ewe - tsala iifayile ezininzi SVG kummandla wokulayisha kwaye sizibeke kwifolokhwe ngokuthe ngqo. Abasebenzisi abakhululekileyo bafumana i-100 MB kwifayili nganye; iPremium ayinalo icebo kwifayili nganye kwaye iqhuba abasebenzi abathe ngqo, ngoko ke umfanekiso we-200-iqela ligqiba ngaphantsi kwemizuzu emibini.

I-SVG ithelekiswa njani ne-PNG kwi-Photoshop / i-GIMP kumsebenzi ofanayo?

Uguqulelo lwefomati ethe ngqo siqhuba i libpng / libjpeg- turbo / libwebp / ImageMagick imijelo yomhleli we desktop osebenzisa, ngemveliso efanayo yobunjani. Utshintsho luhamba ngaphaya kolawulo lweqela - iinkqubo ze desktop zivula ifayile enye ngexesha; siyamkela iqela.

Uphi ubungakanani obuzakubakho kwifayili yam PNG?

Okumiselweyo ku 1:1 — PNG wakho ugcina ubungakanani be-pixels yomthombo SVG. Ukuba ufuna ukuguqula ubungakanani njengenxalenye yokuguqula, sebenzisa /resize-image/ emva kokuguqula, okanye uyibeke kwi- /image-resize/ utility.

Ingaba i PNG incinane kangakanani na ukuba ingabonakali i-artifacts?

Kwi-JPG / WebP, umgangatho we-75-85 ufumana PNG 60-80% omncinane kune-SVG ngaphandle kotshintsho olubonakalayo kumgama wokujonga oqhelekileyo. Kwi-lossless PNG (PNG, TIFF), lindele ukonga okuncinci - ngokuqhelekileyo 5-30% nge-deflate / LZW uxinzelelo olungcono. I-PNG yinketho efanelekileyo yokuthatha imifanekiso yekhusi, ilogos, umzobo womgca nantoni na enemiphetho eqinileyo okanye ebonisa ngaphaya — akukho cingo, akukho mbala obandayo.

Ingaba iifayile zam SVG zifihlakeleyo ngexesha lokuguqulwa?

Ewe — iifayili ezilayishwe phezulu SVG ziqhubekekiswa kubasebenzi abakhethekileyo kwaye zicinywe ngaphakathi kwemizuzu. Asiyi kufunda, sigcine ixesha elide, okanye sinikezele i-pixel data. Ifestile yokugcina epheleleyo ibhalwe kwi /privacy/.
