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

Yini imiphumela ekhona?

Isikali esingwevu, isipi, ukushintsha, ukungqubuzana, ukucasuka, nokukhanya, ukuphikisana nokugqwala. Kungenza zihlanganisene, futhi ukuhlanganisa kuzo esinye isikhala kungcono kunalokho ukufaka ithuluzi ngokuphindaphinda.

Ingabe ifomethi yomsuka ishintsha indlela isihlungi esibukeka ngayo?

Ingaba. 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 ngokulula.

Ingabe ngizosusa isihlungi ngemuva kokulanda?

Akukho - imiphumela ibhakiwe kuma-pixels we-output, okuwukuphela kwento edingekayo ukuyisebenzisa. Gcina ihele elidala; lokhu kuzokwenza ukwenze. Isikali esingwevu kanye nokugqwala ngokukhethekile kususa ulwazi olungeke lubuyiselwe.

Ingabe ngingenza ukubonakala okufanayo kusethulo esigcwele?

Yebo. Isihlungi esisodwa sohlelo lokusebenza sisetshenziswa ku-batch, okuwukuthi indlela othola ngayo i-gallery ehambisanayo ngokubona ngaphezu kwesethulo sezithombe ezihlukile ezi-tweaked ezifana kakhulu.

Ingabe Ama-JPEG ama-filters izonciphisa ukhwalithi ye JPEG images yami?

Umsuka olahlekelwayo usuke umphumela wesikhathi sokungena esingu-1, futhi noma yisiphi isenzo esidinga ukuphinde sikhombise sifaka isithupha. lapho umsebenzi ungakwenziwa khona ngaphandle kokuchofoza i-pixel data sizokwenza lokho endaweni, futhi lapho kungasakwazi khona ukhetha i-quality factor wena ngokwakho ngaphezu kokuthola iphutha eliqinile.

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.

Yini engikwazi ukuyifaka ku Ama-JPEG ama-filters?

Noma yini emndenini we-lossy raster — JPG, JPEG, JFIF ne-WebP — kanye nefomethi engalahleki (PNG, BMP, TIFF) uma ufuna ukuzixhuma ndawonye. Ifomethi ifundwa kusuka kuhele lombhalo ophezulu, hhayi isiqephu, ngakho isithombe esigcinwe nge-suffix engalungile sizoqhubeka sihamba.

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

PDF.to ikhona ngoba i-PDF iyilapho amadokhumende ehamba khona ukuze ahlukaniswe khona futhi indawo ebuhlungu kakhulu yokuzigcina lapho zisebenza khona, ngakho-ke cishe yonke imisebenzi lapha ikhuluma ngokuthola into ngaphakathi noma ngaphandle kwalolu hlelo ngokuzimela. Idokhumende lihlala lifika ezweni elidinga ukushiya kulo: likhulu kakhulu, linomkhawulo ongalunganga, livaliwe, noma i-scan engenambhalo kulo. Ama-JPEG ama-filters ihlala ku-upload efanayo ne-akhawunti efanayo njenge-conversions ngoba lezi misebenzi zivela ndawonye.

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

Umguquli kule ndawo uhambisa amadokhumende phakathi kwe-PDF, i-Word, izithombe, umbhalo ojwayelekile kanye ne-eBook formats nganoma yisiphi isiqondiso, ngakho konke okuphuma kuthuluzi lapha kunendawo yokuya phambili ngaphandle kokufaka okulandelayo. Ukusebenzisa lokhu ngemuva kwe Ama-JPEG ama-filters ngaphezu kokungaphambili kugcina isakhiwo sedokhumende sihle ngokuya ngenyathelo engahle ifane nokuyihlaza.

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

Ama-engine ahlukaniswe - i-document toolchain efanayo, abasebenzi abafanayo, ama-limits afanayo. Okunye okushiwo yi PDF site kukhombisa lapho ifayela lihlala khona i-document futhi lapho lifuna khona ukuba yisona sinye, okuwusinqumo esiningi sezinto ezisebenza ngokucophelela ukwenza kuwe. Kuqala futhi kusuka kuqiniso elinye mayelana nefomethi le site ibizwa ngemuva: i-PDF iyi-graph yento, hhayi isithombe sekhasi, ngakho umbhalo uhlala ukhethwa futhi ama-vectors ahlala aqinile kungakhathaliseki ukuthi kwenzekani ku-raster content ngaphakathi kwayo.

Ngidinga i-akhawunti, futhi yini egcinwa?

Akukho akhawunti, futhi akukho okugcinwa: ukuthunyelwa kususwa abasebenzayo ngemuva komsebenzi ophelile, akukho okufundwayo futhi akukho okuhlobene. Ama-akhawunti amahhala akhona ngembali nenani leqembu, hhayi ukufinyelela.
