Indlela yokuguqula PSD ukuba JFIF

Inyathelo 1: Rhweba ngaphakathi PSD iifayili usebenzisa iqhosha phezulu okanye nge shift nendawo.

Inyathelo 2: Nqakraza kwiqhosha 'Uguqulo' ukuqala uguqulo.

Inyathelo 3: Gcina ifayile yakho eguqulweyo JFIF iifayile

PSD ukuba JFIF Imibuzo Ebuzwa Rhoqo Ngokuguqula

Ndiyiguqula njani i-PSD ibe yi-JFIF ngaphandle kokulahlekelwa umgangatho womfanekiso?

Layisha phezulu ifayili yakho ye PSD, emva koko umguquli wethu ufaka ukuphuculwa komgangatho owaziyo wefomati ye-JFIF imveliso. Kwifomati ezingalahlekiyo (PNG, TIFF, BMP) sigcina zonke ii-pixels; kwifomati ezilahlekiyo (JPG, WebP) ungalungisa isizathu somgangatho phambi kokukhuphela.

Ingaba uguqulelo PSD ukuya ku JFIF lugcina ukubonakala ngaphaya?

Ukubonakala ngaphaya kuqhubeka xa usiya kwi-PNG, WebP, TIFF, GIF okanye SVG. Ukutshintsha kwi-JPG kugubungela isiqhagamshelanisi se-alpha phantsi kwesiqalo esimhlophe - ukuba ufuna ukubonakala ngaphaya, cwangcisa ifomati eyaziyo ukubonakala ngaphaya endaweni ye JFIF.

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

Iiprofayili zombala we-ICC ezifakelweyo zifundwa kumvelaphi PSD kwaye zidityaniswe kwakhona kwi-JFIF yemveliso apho ifomati ixhasa khona (JPG, PNG, TIFF, WebP). Iifomati ezingaxhaswanga zibuyela kwi-sRGB.

Yintoni malunga ne-EXIF metadata xa uguqula PSD ukuya ku JFIF?

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

Ndingaguqula izigidi zeefayili PSD zibe JFIF ngaxeshanye?

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

I-PSD ukuya kwi-JFIF ithelekiswa njani ne-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.

Ingaba i-JFIF iya kuba nesisombululo esinjani na?

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

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

Kwi-JPG / WebP, umgangatho we-75-85 ufumana ifayili i-60-80% incinane kune-PSD yomthombo ngaphandle kotshintsho olubonakalayo kumgama wokujonga oqhelekileyo. Kwiinjongo ezingalahlekiyo (PNG, TIFF), lindele ukonga okuncinci — ngokuqhelekileyo 5-30% nge-deflate / LZW yokucinezela engcono.

Ingaba iifayile zam PSD zifihlakeleyo ngexesha lokuguqulwa?

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

Ingaba i-PSD ukuya kwi-JFIF 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-JFIF iguqulwe ibe mkhulu/ncinane kuneleyo ndiyifumeneyo?

Ifayili PSD enesicitho esinamandla (umzekelo, i-JPG enesicitho esiphezulu) ihlala ikhula xa iphinde ikhowudiwe ibe yi-lossless JFIF (PNG, TIFF), kwaye i-high-bitrate lossless PSD ihlala ikhula ngokugqithisileyo xa ihamba kwi-JPG/WebP. Uthelekiso luxhomekeke kwizinto eziqulethe umfanekiso (iifoto zicitha ngokuhlukileyo kunemizobo yelayini).

Ndingayisebenzisa ifayili eguqulweyo JFIF ngemali?

Ewe. Uguqulelo lutshintsho lwefomati - ilungelo lokushicilela kwimixholo yomfanekiso lihlala kuwe (okanye umntu ophetheyo kumgca womthombo PSD). Sidibanisa akukho phawu lwamanzi, akukho phawu lwemetadata, kwaye sicela akukho layisensi ngaphezulu kwemveliso.

PSD

I-PSD (uXwebhu lwePhotoshop) yifomathi yefayile yemveli ye-Adobe Photoshop. Iifayile ze-PSD zigcina imifanekiso enamaleko, nto leyo evumela ukuhlela okungonakalisiyo nokugcina izinto zoyilo. Zibaluleke kakhulu kuyilo lwemizobo yobungcali kunye nolawulo lweefoto.

JFIF

I-JFIF (i-JPEG File Interchange Format) ime njengefomathi yefayile eguquguqukayo elungiselelwe ngokukodwa utshintshiselwano olungenamthungo lwemifanekiso ekhowudiweyo yeJPEG. Le fomati idlala indima ebalulekileyo ekwandiseni ukuhambelana nokwabelana ngesakhono kwiinkqubo ezahlukeneyo kunye nezicelo. Iqondwa ngolwandiso lwefayile oluqhelekileyo ".jpg" okanye ".jpeg", iifayile ze-JFIF zisebenzisa amandla e-algorithm yoxinzelelo lweJPEG esetyenziswa ngokubanzi, edume ngokusebenza kwayo ekucinezeleni imifanekiso yeefoto.
