GIF ukuba PNG Imibuzo Ebuzwa Rhoqo Ngokuguqula

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

Layisha phezulu ifayile yakho GIF 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-GIF ayilahleki kodwa iphele kwi-256-imibala yengqokelela yezixhobo ngesakhelo ngasinye, isebenzisa uxinzelelo lwe-LZW kunye nokukhanya okubini kombala omnye. 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 GIF yam iphila — yintoni eyenza ezinye ii-frames?

I-frame yokuqala kuphela ehlala, kuba PNG i-format ehlala ikhona engenanto yokugcina enye. Ukuba udweliso lubalulekile, cwangcisa i-format eyenza udweliso, okanye uguqule kwi-video container endaweni yoko ugcine intshukumo. I-PNG yifomati yomfanekiso ophantsi: umfanekiso ogciniweyo njenge-PNG uhlala ukhulu ngee-5 ukuya kwi-10 ngaphezu komfanekiso ofanayo njenge-JPG okanye i-WebP.

Ingaba kukho into elahlekile ekuguquleni phakathi kwe GIF 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 GIF 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.

I-PNG yaphuhliswa ngowe-1996 njengento engekhoyo kwipateni ye-GIF, kwaye yayiyifomati yomfanekiso ongekhoyo kwi-web.

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

Iiprofayili zombala we-ICC ezifakwe ngaphakathi zifundwa ukusuka kwi GIF 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 GIF ukuya PNG?

I-EXIF yekhamera (ISO, i-shutter, i-lens, i-GPS coords) igcinwa ngokumiselweyo ngexesha GIF → 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 GIF zibe PNG ngaxeshanye?

Ewe - tsala iifayile ezininzi GIF 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-GIF 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 GIF. 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-GIF 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.

I-pipeline ijikelezisa imiqolo ukuze ukusetyenziswa kovimba weefayili kulinganiswe ngobalo lomqolo, hayi ubalo lwee-pixels ezipheleleyo.
