JPG ukuba PSD Imibuzo Ebuzwa Rhoqo Ngokuguqula

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

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

Ingaba uguqulelo JPG ukuya ku PSD 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 PSD = JPG.

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

Iiprofayili zombala we-ICC ezifakiwe zifundwa ukusuka kummthombo we JPG kwaye zidityaniswe kwakhona kwi-PSD 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 JPG ukuya ku PSD?

I-EXIF yekhamera (ISO, i-shutter, i-lens, ii-GPS coordinates) igcinwa ngokumiselweyo ngexesha lokuguqulwa JPG → PSD 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 JPG zibe PSD ngaxeshanye?

Ewe — tsala iifayile ezininzi JPG 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-JPG ukuya kwi-PSD 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-PSD iya kuba nesisombululo esinjani na?

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

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

Kwi-JPG / WebP, umgangatho we-75-85 uhlala uvelisa ifayili encinci nge-60-80% kune-JPG 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 JPG zifihlakeleyo ngexesha lokuguqulwa?

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

Ingaba i-JPG ukuya kwi-PSD 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-PSD ifayili yam eguqulweyo incinci okanye ikhulu kuneleyo ndiyifumeneyo?

Ifayili JPG enesici esinamandla (i-JPG enesici esinzima) ihlala ikhula xa iphinde ikhowudiwe ibe yi-lossless PSD (PNG, TIFF); i-bitrate ephezulu enesici esinzima JPG 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 PSD ngemali?

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

JPG

Iifayile zeJPG zisebenzisa i-lossy compression eyenzelwe iifoto, zibonelela ngobukhulu obuncinci beefayile ngelixa zigcina umgangatho obonakalayo.

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.
