PNG ukuba SVG Imibuzo Ebuzwa Rhoqo Ngokuguqula

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

Layisha phezulu ifayile yakho PNG kwaye umguquli usebenzise umgangatho owaziyo wefomati efanelekileyo ye SVG. Ukungabikho kolahleko SVG (PNG, TIFF, BMP) yonke ipixel igcinwa; ukungabikho kolahleko SVG (JPG, WebP) ungalungisa umgangatho womsebenzi 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 SVG lugcina ukubonakala?

Ukubonakala ngaphaya kuqhubeka xa SVG 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 SVG endaweni ye-SVG=JPG. I-SVG yifomati ye-W3C ye-XML-based vector, icebiso ukusukela ngo-2001 kwaye ngoku ivela kumkhangeli zincwadi wonke.

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

Iiprofayili zombala we-ICC ezifakwe ngaphakathi zifundwa ukusuka kwi PNG kwaye zidityaniswe kwakhona kwi-SVG 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 PNG ukuya SVG?

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

Ndingaguqula iifayili ezininzi PNG zibe SVG ngaxeshanye?

Ewe - tsala iifayile ezininzi PNG 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-PNG ithelekiswa njani ne-SVG 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 SVG?

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

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

Kwi-JPG / WebP, umgangatho we-75-85 ufumana SVG 60-80% omncinane kune-PNG ngaphandle kotshintsho olubonakalayo kumgama wokujonga oqhelekileyo. Kwi-lossless SVG (PNG, TIFF), lindele ukonga okuncinci - ngokuqhelekileyo 5-30% nge-deflate / LZW uxinzelelo olungcono. I-SVG ibonisa kakuhle nakweyiphi na ubungakanani, ihlala ihlela, ikhangela kwaye iguqula njengombhalo ocacileyo, kwaye ihlala ilingana nobungakanani be-PNG.

Ingaba iifayile zam PNG zifihlakeleyo ngexesha lokuguqulwa?

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