PNG ukuba SVG Imibuzo Ebuzwa Rhoqo Ngokuguqula

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

Layisha phezulu ifayili yakho ye PNG kwaye umguquli wethu usebenzise ukuphuculwa komgangatho owaziyo ifomati ye SVG imveliso. Kwiinjongo ezingalahlekiyo (PNG, TIFF, BMP) yonke i-pixel igcinwa nge-bit-per-bit; kwiinjongo ezilahlekiyo (JPG, WebP) ungalungisa isizathu somgangatho (okungagqibekanga 90) phambi kokukhuphela. 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. I-SVG igcina iimpawu njengendlela ye-matematics nombhalo njengombhalo, hayi njenge-pixels, ngoko ke luxwebhu kunokuba luyi-raster grid.

Ingaba i PNG imifanekiso iya kuguqulwa ibe yi SVG ecocekileyo?

Kuphela ukuya kwincopho, kwaye kufanelekile ukumisela okulindelekileyo kuqala. Ukubopha kujika imimandla ye-pixel ibe ziindlela, ezisebenza kakuhle kwilogos, umzobo womgca kunye nomfanekiso ongwevu-ombala ocacileyo onemida. Umfanekiso awunamida, ngoko ubopha luvelisa okanye uthelekiso olunobungozi okanye SVG ngeezigidi zeendlela ezikhulu kwaye ezicothayo ukuzoba kunezo zakuqala. I-SVG ayikwazi ukubonakalisa umfanekiso - ukulandelela omnye kwenza ukuba kubekho ukuthelekiswa okunobunzima okanye ifayili enkulu kune-raster ephambili.

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 PNG ne SVG?

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 PNG ukuya ku SVG lugcina ukubonakala ngaphaya?

Ukubonakala ngaphaya kuqhubeka xa SVG yi-PNG, WebP, TIFF, GIF, okanye SVG. Ukutshintsha ukuba yi-JPG kwenza ukuba isiqhagamshelanisi se-alpha sifane nesiqalo esimhlophe — ukuba ufuna ukubonakala ngaphaya, khetha isiphelo esizimelayo esibonisa ngaphaya endaweni ye-SVG. I-SVG yifomati ye-W3C ye-XML-based vector, icebiso ukusukela ngo-2001 kwaye ngoku ivela kumkhangeli zincwadi wonke.

Ingaba i-inkangeleko yam yombala (sRGB / Adobe RGB / CMYK) iya kuhlala i PNG ukuya ku SVG?

Iiprofayili zombala we-ICC ezifakelweyo zifundwa kumvelaphi PNG kwaye zidityaniswe kwakhona kwi-SVG yemveliso apho ifomati ixhasa khona (JPG, PNG, TIFF, WebP). Iifomati ezingaxhaswanga yiprofayili zibuyela kwi-sRGB ngenyathelo elilula lokuqinisekiswa.

Ithini into ebangela ukuba i-EXIF metadata iguqulwe PNG ibe yi SVG?

I-EXIF yekhamera (ISO, i-shutter, i-lens, i-GPS) igcinwa ngokumiselweyo ngexesha PNG -> SVG xa zombini iifayili zixhasa i-metadata. Sebenzisa utshintshi lobumfihlo ukususa i-metadata phambi kokukhuphela ukuba ufuna ukuthumela imifanekiso ngaphandle kokubekwa kwendawo okanye ukubonisa umnwe wesixhobo.

Ndingaguqula izigidi zeefayili PNG zibe SVG ngaxeshanye?

Ewe - rhuqa iifayile ezininzi PNG kwindawo yokulayisha kwaye zifolole ngokuthe tye. Umphakamo osimahla uyamkela i-100 MB ngefayili nganye; i-Premium ayinasiphelo sefayili nganye kwaye iqhuba abasebenzi abathe tye abaninzi, ngoko ke iqela lemifanekiso engama-200 ligqiba ngaphantsi kwemizuzu emibini.

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

Uguqulelo lwefomati olulula siqhuba i libpng / libjpeg- turbo / libwebp / ImageMagick imibhobho efanayo umhleli we desktop asebenzisayo, kwi umgangatho ofanayo. Utshintsho kukuba izixhobo ze desktop zivula ifayile enye ngexesha; siyamkela iqela kwaye siqhuba ngokuthe tye kwiseva- ecaleni kwabasebenzayo.

I-SVG iifayili zinee-resolutions kunye nemilinganiselo eziphi?

Ukuziphatha okungagqibekanga kuku 1:1 — i-SVG yakho yemveliso inezinto ezilinganayo ze-pixels njenge-PNG. Ukuba ufuna ukuguqula ubungakanani njengenxalenye yokuguqula, sebenzisa /resize-image/ emva, okanye ubeke iinzame kwi- /image-pipeline/ utility.

Ingaba i SVG ifayili incinane kangakanani na ukuba ayinazo izinto ezibonakalayo ezibonakalayo?

Kwi-JPG / WebP, umgangatho we-75-85 uhlala uvelisa i-SVG 60-80% encinci kune-PNG ngaphandle kotshintsho olubonakalayo kumgama wokujonga oqhelekileyo. Kwi-SVG engenanto (PNG, TIFF), lindele ukonga okuncinci — ngokuqhelekileyo 5-30% nge-deflate / LZW yokucinezela engcono kuneleyo umboneleli sele uneyo. I-SVG ibonisa kakuhle nakweyiphi na ubungakanani, ihlala ihlela, ikhangela kwaye iguqula njengombhalo ocacileyo, kwaye ihlala ilingana ne-PNG.

Ingaba iifayile zam PNG zifihlakeleyo ngexesha lokuguqulwa?

Ewe — iifayile ezilayishwe phezulu PNG ziqhubekekiswa kubasebenzi abakhethekileyo kwaye zicinywe kwimizuzu. Asizukufunda, sigcine, okanye sisebenzise i-pixel data. Ifestile yokugcina epheleleyo ibhalwe kwi /privacy/.

PNG

Iifayili ze-PNG ziqhubekeka ngokucacileyo kwaye zisebenzisa ukucinezela okungalahleki, zenza ukuba zilungele amagrafiki, ilogos, kunye nemifanekiso yekhusi.
