Yini mayelana ne-EXIF metadata uma uguqula JFIF usuka ku-JPEG?

Kuzo zonke izishintsho, ama-EXIF ama-camera afana nemodeli ye-camera nendawo ye-GPS afakwanga ku-JPEG. Akukho sinqumo kule khasi sokugcina noma ukususa i-metadata, ngakho hlola imiphumela ngombonisi we-metadata uma kubaluleke.

Ingabe ngingenza ukuguqulwa kwekhulu le JFIF amafayela ku JPEG ngasikhathi sinye?

Amafayela amaningi emisebenzini eyodwa adinga iphrojekthi ekhokhelwa. Ukusetshenziswa okumahhala kuyisifayela esisodwa ngasinye sokuguqulwa, ukuguqulwa okufanayo ngehora. Kuphrojekthi ekhokhelwa ungangeza amafayela amaningi kumsebenzi owodwa, bese ulanda impendulo ngayinye yayo noma zonke ku-ZIP eyodwa.

Yini isixazululo kanye nezici zehele lami JPEG?

Ukuziphatha okuzenzakalelayo yi-1:1 — i-JPEG yakho yesokudla inezici ze-pixel ezifanayo ne-JFIF. Sebenzisa isikhashana /ukuguqula-isifanekiso/ esisodwa ngemuva kokuguqulwa uma ufuna ukuncipha noma ukuphakama njengengxenye yokuhamba komsebenzi.

Ingabe ihele JPEG lincane uma kungabonakali izinto ezibonakalayo?

I-JPG / WebP, ikhwalithi engu-75-85 ithola ihele elincincane ngama-60-80% kunalomthombo JFIF ngaphandle koshintsho olubonakalayo emgwaqweni wokubuka ojwayelekile. Inhloso engalahleki (PNG, TIFF), cabanga ukulondoloza okuncane — ngokuvamile 5-30% nge-deflate / LZW yokucindezela okungcono.

Yebo. Amafayela JFIF alayishwe phezulu aphathwa kumaseva ethu ahlukile futhi angeke abone noma ahlukaniswe. Amafayela alayishwe phezulu namasithombe aguqulwe asuswa ngokuzenzakalela cishe amahora angu-24 ngemuva kokuguqulwa. Inqubomgomo yobumfihlo egcwele itholakala ku /privacy/.

Kungani ihele lami eliguqulwe JPEG likhulu / lincane kunalokho engilindele?

Ihele JFIF elinamandla okucindezeleka (isibonelo, iJPG enamandla okucindezeleka) likhula lapho liphinde likhonjiswa ku JPEG (PNG, TIFF) elingasebenzisi amandla, futhi i-bitrate ephezulu engenamsebenzi JFIF lincipha kakhulu lapho liya ku-JPG / WebP. Izinga lixhomekeka kusithombe esiqukethwe (izithombe zicindezeleka ngendlela eyahlukileyo kunaleyo ye-line art).

Ingabe ngisebenzisa ifayela eliguqulwe JPEG ngebhizinisi?

Yebo. Ukuguquka kuyisimo soshintsho - ilungelo lokushicilela kusithombe sihlala kuwe (noma umuntu ophethe isithombe kumthombo JFIF). Sifaka i-watermark, i-metadata stamp, futhi sicela ilayisense ngaphezulu kwe-output.
