WebP ukuba PNG Imibuzo Ebuzwa Rhoqo Ngokuguqula

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

Layisha phezulu ifayili yakho ye WebP kwaye umguquli usebenzise ukuphuculwa komgangatho owaziyo ifomati yemveliso ye PNG. Kwiinjongo ezingalahlekiyo (PNG, TIFF, BMP) yonke i-pixel igcinwa; kwiinjongo ezilahlekiyo (JPG, WebP, AVIF) ungalungisa isizathu somgangatho phambi kokukhuphela.

Ingaba uguqulelo WebP ukuya ku PNG lugcina ukubonakala ngaphaya?

Ukubonakala ngaphaya kuqhubeka xa usiya kwi-PNG, WebP, TIFF, GIF, okanye SVG. Ukutshintsha kwi-JPG kugubungela isiqhagamshelanisi se-alpha phantsi kokungasemva omhlophe - ukuba ukubonakala ngaphaya kubaluleke kakhulu kwimisebenzi yakho (ukubonakala ngaphaya kwe-web, ilogos), cwangcisa ifomati eyaziyo ukubonakala ngaphaya endaweni ye PNG = JPG.

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

Iiprofayili zombala we-ICC ezifakiwe zifundwa ukusuka kummthombo we WebP kwaye zidityaniswe kwakhona kwi-PNG apho ifomati ixhasa khona (JPG, PNG, TIFF, WebP). Iifomati ngaphandle koxhaso lweprofayili zibuyela kwi-sRGB. Ukuhamba komsebenzi we-CMYK we-shop-print ujikeleza ngokuchanekileyo nge-TIFF ne-high-bit JPG.

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

I-EXIF yekhamera (ISO, i-shutter, i-lens, ii-GPS coordinates) igcinwa ngokumiselweyo ngexesha lokuguqulwa WebP → PNG xa zombini iifayili zixhasa i-metadata. Sebenzisa ukhetho lobumfihlo ukususa i-metadata phambi kokukhuphela ukuba ufuna ukuthumela imifanekiso ngaphandle kokuveza indawo ebekwe kuyo okanye isixhobo sokufota.

Ndingaguqula izigidi zeefayili WebP zibe PNG ngaxeshanye?

Ewe — tsala iifayile ezininzi WebP kwindawo yokulayisha kwaye sizibeke kwifolokhwe ngokuthe tye. Abasebenzisi abakhululekileyo bafumana ukuya kuthi ga kwi-100 MB ngefayili nganye; iPremium ayinaso isiphelo sefayili nganye kwaye iqhuba abasebenzi abathe tye abaninzi, ngoko ke iqela lemifanekiso engama-200 ligqiba ngaphantsi kwemizuzu emibini.

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

Uguqulelo lwefomati siqhuba i libpng / libjpeg- turbo / libwebp / ImageMagick imibhobho efanayo umhleli we desktop ayisebenzisayo, ngemveliso efana neyona. Utshintsho luhamba - isixhobo se desktop siphatha ifayile enye ngexesha; siyayamkela iqela kwaye siqhuba ngaphaya kweseva- icala.

Ingaba i-PNG iya kuba nesisombululo esinjani na?

Ukuziphatha okungamiselwanga kuku 1:1 — i-PNG yakho yemveliso inezinto ezilinganayo ze-pixels njenge-WebP yommthombo. Ukuguqula ubungakanani njengenxalenye yokuguqula, sebenzisa /resize-image/ phambi okanye emva kwesi sigqibo. Ukuqhagamshelana kukhawulezayo kunekuphinde ukwenziwa kubungakanani obutsha ngaphakathi kwenkqubo yokuguqula.

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

Kwi-JPG / WebP, umgangatho we-75-85 uhlala uvelisa ifayili encinci nge-60-80% kune-WebP yombhalo ovela kumbhalo oqhelekileyo ngaphandle kotshintsho olubonakalayo kumgama wokujonga. Kwiinjongo ezingalahlekiyo (PNG, TIFF), lindele ukonga okuncinci — ngokuqhelekileyo 5-30% nge-deflate / LZW yokucinezela engcono kune-source esetyenziswayo.

Ingaba iifayile zam WebP zifihlakeleyo ngexesha lokuguqulwa?

Ewe — iifayile ezilayishwe phezulu WebP ziqhubekekiswa kubasebenzi abakhethekileyo kwaye zicinywe kwimizuzu. Asizukufunda, sigcine, okanye sisebenzise i-pixel data. Inkqubo yobumfihlo obupheleleyo kunye nefestile yokugcina ibhalwe kwi /privacy/.

Ingaba i-WebP ukuya kwi-PNG iguqula imifanekiso emikhulu kakhulu (i-50 MP nangaphezulu)?

I-premium iphatha izingeniso ezinkulu (300 MB+) kunye nobunzulu obuphezulu be-pixel nganye (16-bit PNG, 32-bit float TIFF). I-pipeline isasaza imiqolo ye-pixel, ngoko ke ukusetyenziswa kwememori kulinganiselwa ngobalo lomqolo hayi ubalo lwe-pixel jikelele — umfanekiso we-100-megapixel uguqulwa kwindlela yokugcina efanayo njenge-10-megapixel.

Kutheni i-PNG ifayili yam eguqulweyo incinci okanye ikhulu kuneleyo ndiyifumeneyo?

Ifayili WebP enesici esinamandla (i-JPG enesici esinzima) ihlala ikhula xa iphinde ikhowudiwe ibe yi-lossless PNG (PNG, TIFF); i-bitrate ephezulu enesici esinzima WebP ihlala ikhula incinci kakhulu ifike kwi-JPG / WebP. Uthelekiso luxhomekeke kwizinto eziqulethe umfanekiso — iifoto zicinywa ngendlela eyahlukileyo kakhulu kunaleyo yomzobo womgca okanye imifanekiso eqingqiweyo yekhusi.

Ndingayisebenzisa ifayili eguqulweyo PNG ngemali?

Ewe. Uguqulelo lutshintsho lwefomati kuphela - ilungelo lokushicilela kwizinto eziqulethe umfanekiso lihlala kuwe (okanye umntu ophetheyo kumgca womthombo WebP). Asifakwanga uphawu lwamanzi, asifakwanga ii-pixels zokulandelela, kwaye asiyi kufaka isicelo selayisensi ngaphezulu kwe-PNG.
