Indlela yokujikelezisa JFIF

1 Layisha phezulu i JFIF images ephuma ngendlela engalungile.

2 Khetha ujikelezo lwesikhashana noma ujikelezo lwesikhashana, noma ubhale i-angle efanele futhi ukhethe umbala wezinhlangothi ezizovela.

3 Sebenzisa ukujikeleza; ama-pixels neflegi yobubanzi bulinganiswe ukuze wonke umbukeli avume ukuthi indlela iphezulu yini.

4 Layisha phezulu ifayela elijikelezayo JFIF.

Jikelezisa JFIF Imibuzo Evame Ukubuzwa

Ingabe ifomu lisho ukuthi ngabe ukujikeleza kungeke kulahleke?

Isebenza. I-JFIF iyi-JPEG bitstream elula ngaphansi kwesihloko soshintsho olusemthethweni 1992, ngakho-ke abanye ababukeli babonisa njengesithombe esijwayelekile futhi amakhamera aqhubeka nokuyikhipha. Le mpahla ilungile ngoba ichaza ukuthi ngabe isigamu sosuku sikhululekile noma izindleko ziphinde zikhodwe.

Ingabe kukhona okuthile okukhethekile ku JFIF okufanele ngikwazi?

Yebo — Abahleli abaningi babhala kabusha i-JFIF njenge-JPEG ejwayelekile uma begcina, ngakho gcina okujwayelekile uma isiqephu se-.jfif sibalulekile kunoma yini esebenzisa ihele. Le yinto echaza ukuthi kungani ifayela libonakale lilungile kuhlelo oluthile futhi lingekho kulunye.

Kungani ifayela lami libonakale lilungile kufoni yami kodwa lihamba ngakwesobunxele kwezinye izindawo?

Ngenxa yokuthi uhlangothi lugcinwa njenge-EXIF flag hhayi kuma-pixels, futhi akukho okubonayo wonke owenza lokhu. Ukujikeleza lapha kujwayelekile okubini — ama-pixels ne-flag aphele ngokuvumelana, ngakho ihele libukeka lifana kuwo wonke amanye.

Indlela eJikelezisa JFIF ejikelezisa ngayo ifayela?

Ngokucacile, ukujikeleza ngezinga le-90 degrees kwenziwa ngaphandle kokulahlekelwa ngokufaka ama-blocks we-DCT - akukho uku-code kabusha, akukho ukulahlekelwa kokukhiqiza; i-angle efanele kuphela edinga ukusatshalaliswa kabusha, ngoba i-pixel grid idinga ukuvuselelwa. Izinhlamvu ezingu-4 kanye nezinhlamvu ezingu-5 ziyisibonelo esijwayelekile futhi zithatha indlela elula kakhulu etholakalayo yefomethi.

Ingabe ngizosebenzisa Jikelezisa JFIF ku JFIF 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 kunesilinganiselo sobukhulu behele ku Jikelezisa JFIF?

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.

Ingabe Jikelezisa JFIF izonciphisa ukhwalithi ye JFIF images yami?

Umsuka olahlekelwayo usuke umphumela wesikhathi sokungena esingu-1, futhi noma yisiphi isenzo esidinga ukuphinde sikhombise sifaka isithathu. 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.

Kungani i Word site i host Jikelezisa JFIF?

WORD.to ikhiwa ngaphesheya kwesokudla sokugcina esihleliwe sempilo yedokhumende — i-DOCX eqhubeka nokubhalwe, eqhubeka nokuhlelwa futhi eqhubeka nokuhlelwa, ngaphambi kokuba umuntu ayenze ibe mhlophe ukuthunyelwa. Amafayela we-Office ayizitolo ezigcwele izithako zabanye abantu - izithombe, umsindo ofakwe, amafonti - ngakho-ke umsebenzi odinga ukuwuthola abantu kulokhu kuvame ukuba umsebenzi odinga ukuwuthola kulezi zinto eziqukethwe. Jikelezisa JFIF ihlanganisa uku-upload, ama-caps ne-akhawunti ngokuguqulwa ngenxa yale sizathu.

Yini okufanele ngiyenze ngemiphumela uma i Jikelezisa JFIF iqediwe?

Umguquli kule ndawo uthatha amadokhumende ePDF ukuthunyelwa, kuzithombe ukufakelwa kanye nombhalo ojwayelekile nganoma yini edinga ukuwafunda ngokuzenzakalela, futhi ubuyela emuva ngenye indlela. Ukwenza lokhu ngemuva kugcina okuzenzakalelayo okuhleliwe, okuyingxenye ongayithola emuva uma iphathwe.

Ingabe Jikelezisa JFIF lapha ithuluzi elifanayo lezindawo ezifanayo ezisebenza?

Ama-engine ahlukaniswe - i-document toolchain efanayo, abasebenzi abafanayo, ama-limits afanayo. I-Word site engeza ukubukeka kwento ephilayo eshiya i-Office format futhi yini engakwenzanga, okuyimibuzo ngayinye yalezi misebenzi empeleni ishintsha. Iqala futhi kusuka kuqiniso elinye mayelana nefomethi le-site ibizwa ngemuva: idokhumende liyi-zip ye-XML, ngakho ukuhlela umbhalo kubiza kakhulu futhi ubunzima buhlala bufana nezithombe ezifakwe.

Ngidinga i-akhawunti, futhi yini egcinwa?

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