WebP ukuba PNG Imibuzo Ebuzwa Rhoqo Ngokuguqula

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

Inceda ukwazi ukuba yintoni ecaleni ngalinye kweli: I-WebP ihambisa zombini i-VP8 elahlekile kunye ne-VP8 engalahlekiyo kunye ne-alpha epheleleyo, ehlala iwela 25-35% phantsi kwe-JPG ehambelanayo nomgangatho obonakalayo, ngelixa I-PNG yi-DEFLATE engalahlekiyo enesiqhagamshelanisi esipheleleyo se-8-bit alfa kunye nobunzulu obukhethwayo be-16-bit, ngoko ke ayizukuhlanganiswa kwi-re-save kodwa ifumana uninzi kwizinto eziqulethe imifanekiso. Layisha phezulu ifayile yakho WebP kwaye umguquli wethu usebenzise umgangatho owaziyo wefomati efanelekileyo ye PNG imveliso - kuba injongo engalahlekiyo (PNG, TIFF, BMP, PSD) yonke ipixel igcinwa; kuba injongo elahlekiyo (JPG, WebP, GIF) ungalungisa umgangatho womsebenzi phambi kokukhuphela.

Ingaba uguqulelo WebP ukuya PNG lugcina ukubonakala?

Ukubonakala ngaphaya kuqhubeka xa usiya kwi-PNG, WebP, TIFF, GIF, ICO, PSD okanye SVG. Ukutshintsha kwi-JPG / JPEG / JFIF kugubungela isiqhagamshelanisi se-alpha phantsi kokungasemva omhlophe — ukuba ufuna ukubonakala ngaphaya, cwangcisa ukubonakala ngaphaya-ulwazi lwefomati endaweni ye PNG.

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

Iiprofayili zombala we-ICC ezifakelweyo zifundwa ukusuka kumsuka WebP kwaye zidityaniswe kwakhona kwi-PNG i-output apho ifomati ixhasa khona (JPG, PNG, TIFF, WebP, PSD). Iifomati ezingaxhaswanga yiprofayili (GIF, BMP, ICO, SVG) zibuyela kwi-sRGB.

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

Ikhamera EXIF (ISO, i-shutter, i-lens, i-GPS) igcinwa ngokumiselweyo ngexesha WebP → PNG uguqulo xa zombini iifomati zixhasa i-metadata (JPG, TIFF, WebP, PSD). Sebenzisa ukhetho lobumfihlo ukususa i-metadata phambi kokukhuphela ukuba ufuna ukubonelela ngemifanekiso ngaphandle kolwazi lwendawo.

Ndingaguqula izigidi zeefayili WebP zibe PNG ngaxeshanye?

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

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

Ukuguqula ifomati ngokulula siqhuba i libpng / libjpeg- turbo / libwebp / ImageMagick imibhobho efanayo umhleli we desktop esebenzisa, ngemveliso efanayo yobunjani. Utshintsho luyizinto ze desktop ezivula ifayile enye ngexesha; jpg. to ivuma iqela kwaye iqhuba ngokuthe tye.

Yintoni isisombululo kunye nemilinganiselo ekufuneka ifayile yam PNG ithathe?

Ukuziphatha okungagqibekanga ku 1:1 — i PNG yakho yemveliso ineempawu ezifanayo ze-pixels njengemvelaphi WebP. I-ICO yemveliso yi-exception (ivelisa umqulu onamandla okubonisa: 16/32/48/64/128/256). Ukuba ufuna ukuguqula ubungakanani njengenxalenye yokuguqula, sebenzisa /resize/ emva kokuguqula.

Ingaba incinci kangakanani ifayili PNG ngaphandle kwee-artefacts ezibonakalayo?

Kwi JPG / JPEG / WebP, umgangatho we 75-85 ufumana ifayile 60-80% incinane kunendawo yomthombo WebP ngaphandle kotshintsho olubonakalayo kumgama wokubona oqhelekileyo. Kwimiba engekhoyo (PNG, TIFF, BMP), lindele ukonga okuncinci - ngokuqhelekileyo 5-30% nge-deflate / LZW uxinzelelo olungcono.

Ingaba iifayile zam WebP zifihlakeleyo ngexesha lokuguqulwa?

Ewe — iifayili ezilayishwe phezulu WebP ziqhutywa ngabasebenza ngokuzimeleyo kwaye zicinywe kwimizuzu. Asiyi kufunda, ukugcina, okanye ukubonelela ngee-pixel data. Inkqubo yobumfihlo obupheleleyo kunye nefestile yokugcina ibhalwe kwi /privacy/.

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

Ewe, simahla ukuya kwi-100MB. I-Premium iphatha izingeniso ezinkulu (300MB+) kunye nobunzulu obungenakulinganiswa kwi-pixel nganye (16-bit PNG, 32-bit float TIFF, multi-layer PSD). I-pipeline ijikelezisa imiqolo ye-pixel, ngoko ukusetyenziswa kovimba weefayili kulinganiselwa ngobalo lomqolo hayi ngobalo lwe-pixel jikelele.

Kutheni le nto ifayili yam eguqulweyo PNG ikhulu / incinci kuneleyo ndiyifumeneyo?

Ubungakanani bumiselwe ziimodeli ezimbini zokucinezela, hayi ngumguquli. Khumbula ukuba I-WebP ihambisa zombini i-VP8 elahlekile kunye ne-VP8 engalahlekiyo kunye ne-alpha epheleleyo, ehlala iwela 25-35% phantsi kwe-JPG ehambelanayo nomgangatho obonakalayo, ngelixa I-PNG yi-DEFLATE engalahlekiyo enesiqhagamshelanisi esipheleleyo se-8-bit alfa kunye nobunzulu obukhethwayo be-16-bit, ngoko ke ayizukuhlanganiswa kwi-re-save kodwa ifumana uninzi kwizinto eziqulethe imifanekiso — ngoko okunzima-ukucinezela WebP kuqhelekileyo UKULUNGISA xa kuphinde kukhowudiwe kwi PNG engalahli, kwaye i-bulky engalahli WebP kuqhelekileyo ikhutshwa ngokuqinileyo isiya kwelinye icala. Imixholo yomfanekiso ibalulekile: iifoto kunye ne-flat line art zicinezela ngokuhlukileyo.

Ndingayisebenzisa ifayili eguqulweyo PNG ngorhwebo?

Ewe. Uguqulelo luguqulelo lwefomati - ilungelo lokushicilela kwizinto eziqulethe umfanekiso lihlala kuwe (okanye umntu ophetheyo kumcebo WebP). Sidibanisa akukho phawu lwamanzi, akukho phawu lwe metadata, kwaye sicela akukho layisensi ngaphezulu kwemveliso.
