Indlela yokufaka izihlungi ku JPEG

1 Layisha phezulu i JPEG images ofuna ukuyiphatha.

2 Khetha izinguquko zakho - isikali esingwevu, isibani, shintsha, ubuso, ubuso obumnyama, ukukhanya, u kontrasti kanye nokulungiswa - futhi umisele amandla ngalinye.

3 Sebenzisa zonke ezihamba ngasinye ngaphandle kokuqhuba ithuluzi ngokuphindaphinda, okuzodala ukulahleka okubonakalayo.

4 Layisha phezulu ifayela elihlanzekile JPEG, futhi ugcine okuqala kwakho: lokhu kuyisiqephu esingenalutho osinikwe.

Ama-JPEG ama-filters Imibuzo Evame Ukubuzwa

Ingabe ifomethi yomsuka ishintsha indlela isihlungi esibukeka ngayo?

Kungenza. I-JPEG iyi-codec efanayo ne-JPG ngaphansi kwesiqiniseko eside — i-DCT pipeline efana, amathebulethi okulinganisela afana, akukho okushintshayo nge-pixels ngegama lefayela. Ububanzi bombala kanye nemodeli yephakeji ngokukhethekile ikhetha ukuthi i-gradient noma ukubhujiswa kungabonakaliswa kanjani.

Yini okukhethekile ku JPEG ongayigcina engqondweni?

Yebo — i.jpeg ne.jpg izixhumanisi ziyi-bitstream efanayo, ngakho akukho okuthile lapha okuzosebenza ngokuhlukile ku-.jpg — igama lefayela kuphela elishintshayo. Lokhu kuyinto evame ukuhluka phakathi kwemiphumela ebukeka ihlanzekile nebukeka ibanda.

Ingabe ngizosusa isihlungi ngemuva kokulanda?

Hayi — imiphumela ibhakiwe kuma-pixels we-output, okuwukuphela kwento ongayisebenzisa. Gcina ifayela eliyinhloko; lokhu kuzokwenza ukwenze. Isikali esingwevu kanye nokugqwala ngokukhethekile kususa ulwazi olungenalutho olungeke lubuyiselwe.

Ingabe ngingenza ukubonakala okufanayo kusethulo esigcwele?

Yebo. Isihlungi esisodwa sohlelo lokusebenza sisetshenziswa ku-batch, ngakho-ke uthola i-gallery ehambisanayo ngokubona ngaphezu kwesethulo sezithombe ezi-tweaked ngazo zonke ezifana kakhulu.

Ingabe ngizosebenzisa Ama-JPEG ama-filters ku JPEG images amaningi ngasikhathi sinye?

Yebo. Thola isethulo esigcwele endaweni yokulayisha bese zihamba ngokufanayo nezilungiselelo ezifanayo - lokhu kuyisizathu esiyinhloko sokwenza lokhu kubrowser ngaphezu kwefayela elilodwa ngasikhathi sinye kumhleli. Ama-akhawunti amahhala aqhuba ifayela elilodwa ngasikhathi sinye; i-pass lifts that.

Yini ekwenzeke ku-EXIF nedatha yeprofayili yombala?

Ikhamera EXIF (ISO, i-shutter, i-lens, GPS) neprofayili efakwe ngaphakathi ye-ICC idluliselwa ngokuzenzakalela, ngoba ukushiya iprofayili kwenza umbala ushintshe uma ufaka kabusha. Sebenzisa ukhetho lokufihla ukususa i-metadata ngaphambi kokulayisha uma uhlela ukushicilela ifayela.

Ingabe Ama-JPEG ama-filters ibiza noma yini?

No. Ama-JPEG ama-filters ikhululekile ngaphandle kwe-akhawunti, akukho uphawu lwamanzi ku-output futhi akukho mnyango wokubhalisa phambi kokulanda. Ukulayisha kususwa ngokuzenzakalela isikhathi esincane ngemuva komsebenzi ophelile.

Ingabe kunesilinganiselo sobukhulu behele ku Ama-JPEG ama-filters?

Yebo: ama-akhawunti amahhala asebenza ngezithombe kuze kube yi-5 MB ngayinye, ehlanganisa ngokuyinhloko yonke ikhamera JPG nesithombe sefoni; umsebenzi ukwenziwa yi-libjpeg-turbo ne-libwebp, ama-library afanayo umhleli wedesktop uxhumana nawo. Amafayela amakhulu yizinto ezincane ezizokuvimbela ukungena ku-free level, futhi umkhawulo uhele ngalinye hhayi iqembu ngalinye.

Kungani i PNG site i host Ama-JPEG ama-filters?

PNG.to ifakwe ngaphansi kwefomethi oyisebenzisayo uma ungakwazi ukulahlekelwa yi-pixel: ayilahleki, ikwazi ukubhala, futhi yisinqumo esilungile sezithombe-skrini, izibonisi, umdwebo we-line kanye nanoma yini eneziphetho ezinzima. Isithombe somsebenzi sincane kakhulu isikhashana: abantu bafika ukushintsha ifomu futhi bashiye isithombe esidinga ubukhulu obuhlukile, ubunzima obuhlukile noma ifomu elihlukile. Ukuhamba Ama-JPEG ama-filters ku-upload pipeline efanayo, ubukhulu obufanayo be-caps kanye ne-akhawunti efanayo yisizathu esigcwele ukuthi ikhona ngaphezu kwe-tab yesi-4.

Yini okufanele ngiyenze ngemiphumela uma i Ama-JPEG ama-filters iqediwe?

Umguquli kule ndawo uhambisa izithombe ku-PNG, JPG, WebP, GIF ne SVG — okuwusuku oluzothatha isigqibo mayelana nokubukeka okucacile. Lolu hlelo luyisinqumo abantu abaningi befika kuso, futhi ukwenze ngemuva kwe-Ama-JPEG ama-filters ngaphezu kokungaphambili kusho ukuthi ukuguqulwa kusebenza kusuka kuhele okuphelelwe isikhathi.

Ingabe Ama-JPEG ama-filters lapha ithuluzi elifanayo lezindawo ezifanayo ezisebenza?

Ama-engine ahlukaniswe — ama-library afanayo, abasebenzi abafanayo, ama-limits afanayo. Okunye okuhlukile yi-advice, futhi i-advice lapha iqala kusuka kuqiniso elilodwa mayelana nefomethi lendawo ibizwa ngemuva: Akukho sinqumlisi somgangatho esingakwazi ukukhohlwa — i-PNG ihamba ngezinyawo ngokucophelela, ngakho into eyodwa kuphela eguqula izindleko zakho yisayizi yefayela. I PNG site icabanga ukuthi i PNG iyindawo efanele yokufinyelela futhi lapho ayikhona, futhi ukuthi uhlolo lungcono kuneqhosha.

Ngidinga i-akhawunti, futhi yini egcinwa?

Akukho akhawunti, futhi akukho okugcinwa: ukuthunyelwa kususwa abasebenzayo ngemuva komsebenzi oqediwe, futhi akukho okuzokwenziwa, okudwetshwe noma okusetshenziswa nganoma yini enye. Ama-akhawunti amahhala akhona ngembali nenani leqembu, hhayi ukufinyelela.
