PNG ukuba GIF Imibuzo Ebuzwa Rhoqo Ngokuguqula

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

Layisha phezulu ifayile yakho PNG kwaye umguquli usebenzise umgangatho owaziyo wefomati efanelekileyo ye GIF. Ukungabikho kolahleko GIF (PNG, TIFF, BMP) yonke ipixel igcinwa; ukungabikho kolahleko GIF (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-GIF ayilahleki kodwa iphele kwi-256-imibala yengqokelela yezixhobo ngesakhelo ngasinye, isebenzisa uxinzelelo lwe-LZW kunye nokukhanya okubini kombala omnye.

Ingaba kukho into elahlekile ekuguquleni phakathi kwe PNG ne GIF?

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 GIF lugcina ukubonakala?

Ukubonakala ngaphaya kuqhubeka xa GIF 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 GIF endaweni ye-GIF=JPG. I-GIF yifomati ye-CompuServe ye-1987, kwaye isizathu esifanayo esiphilayo kukuba ibonisa ubugcisa.

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

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

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

Okumiselweyo ku 1:1 — GIF 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 GIF incinane kangakanani na ukuba ingabonakali i-artifacts?

Kwi-JPG / WebP, umgangatho we-75-85 ufumana GIF 60-80% omncinane kune-PNG ngaphandle kotshintsho olubonakalayo kumgama wokujonga oqhelekileyo. Kwi-lossless GIF (PNG, TIFF), lindele ukonga okuncinci - ngokuqhelekileyo 5-30% nge-deflate / LZW uxinzelelo olungcono. Umfanekiso ojikelezayo we GIF udlala ngokucacileyo naphi na - abaxhasi be-imeyili, iiforums, iinkqubo zokuncokola kunye neebrowser zonke ziyibonisa ngaphandle konxibelelwano lwe-codec.

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/.

Ingaba i-PNG ukuya kwi-GIF iguqulela isebenza kwimifanekiso emikhulu kakhulu (50MP+)?

Ewe, simahla ukuya kwi-100 MB. I-Premium iphatha izingeniso ezinkulu (300 MB+) kunye nobunzulu obungenakulinganiswa kwi-pixel nganye (16-bit PNG, 32-bit float TIFF). I-pipeline ijikelezisa imiqolo ukuze ukusetyenziswa kovimba weefayili kulinganiswe ngobalo lomqolo, hayi ubalo lwee-pixels ezipheleleyo.

Kutheni i GIF yam eguqulweyo ikhula okanye incinci kuneleyo ndiyifumeneyo?

A PNG nge-compression enamandla ekhoyo (i-lossy JPG) ihlala ikhula xa iphinde ikhowudiwe kwi-lossless GIF (PNG, TIFF). I-lossless PNG ihlala ikhula ngokugqithisileyo xa isiya kwi-JPG / WebP. Uthelekiso luxhomekeke kwizinto eziqulethe umfanekiso - iimifanekiso zicofa ngokuhlukileyo kumfanekiso womgca. I-PNG yifomati yomfanekiso ophantsi: umfanekiso ogciniweyo njenge-PNG uhlala ukhulu ngee-5 ukuya kwi-10 ngaphezu komfanekiso ofanayo njenge-JPG okanye i-WebP. I-GIF's 256-imibala ye-ceiling ilahla i-gradients kunye nevidiyo ehlala, kwaye ubungakanani befayili yayo yobuchule bunomlinganiselo onzima kune-WebP okanye i-MP4.
