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

Ndingaguqula izigidi zeefayili JFIF zibe PSD ngaxeshanye?

Ewe - tsala iifayile ezininzi JFIF kwindawo yokulayisha kwaye sizibeke kwifolokhwe ngokuthe tye. Abasebenzisi abakhululekileyo bafumana i-100MB ngefayili nganye; iPremium ayinasiphelo sefayili nganye kwaye iqhuba abasebenzi abathe tye abaninzi, ngoko ke iqela lemifanekiso engama-200 ligqiba ngaphantsi kwemizuzu emibini.

I-JFIF ithelekiswa njani ne-PSD kwi-Photoshop / i-GIMP kumsebenzi ofanayo?

Uguqulelo lwefomati olulula siqhuba i libpng / libjpeg- turbo / libwebp / ImageMagick imibhobho efanayo umhleli we desktop usebenzisa, ngexabiso elifanayo. Utshintsho luyizinto ze desktop zivula ifayile enye ngexesha; siyamkela iqela kwaye siqhuba ngokuthe tye.

Yintoni isisombululo kunye nemilinganiselo yefayili yam PSD?

Ukuziphatha okungagqibekanga ku 1:1 — i PSD yakho yemveliso inezinto ezilinganayo ze-pixels njengemvelaphi JFIF. Ukuba ufuna ukuguqula ubungakanani njengenxalenye yokuguqula, sebenzisa i /resize-image/ isixhobo emva kokuguqula, okanye uyibeke kwi- /image-resize/ utility.

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

Kwi JPG / WebP, umgangatho we 75-85 ufumana ifayile ye 60-80% encinci kunesiqulathi seefayili JFIF ngaphandle kokungafani okubonakalayo kumgama wokujonga oqhelekileyo. Kwizinjongo ezingalahlekiyo (PNG, TIFF), lindele ukonga okuncinci - ngokuqhelekileyo 5-30% nge-deflate / LZW uxinzelelo olungcono.

Ingaba iifayile zam JFIF zifihlakeleyo ngexesha lokuguqulwa?

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

Ingaba i-JFIF ukuya kwi-PSD iguqula imifanekiso enkulu kakhulu (50MP+)?

Ewe, simahla ukuya kwi-100MB. I-Premium iphatha izingeniso ezinkulu (300MB+) kunye nobunzulu obukhethekileyo kwi-pixel nganye (16-bit PNG, 32-bit float TIFF). I-pipeline isasaza imiqolo ye-pixel, ngoko ke ukusetyenziswa kwememori kulinganiselwa ngobalo lomqolo hayi ngobalo lwe-pixel jikelele.

Kutheni i-PSD yam eguqulweyo ifile incinci / ikhulu kuneleyo ndiyifumeneyo?
