Ukulayisha

Indlela yokulinganisa JPEG

1 Layisha phezulu i JPEG images oyifunayo iphindwe.

2 Khetha i-axis - i-horizontal ikunikeza isithombe se-mirror, i-vertical ikunikeza ukubukeka okuhlanganisiwe.

3 Sebenzisa ukushintsha, bese ubheka noma iyiphi incwadi, ilogo noma inani embonini, ngoba lezo zifana nezinye zonke izinto.

4 Layisha phezulu ifayela elishintshiwe JPEG.

Phendula Isithombe Imibuzo Evame Ukubuzwa

Ingabe kukhona okuthile okukhethekile ku JPEG okudinga ukukwazi?

Yebo — i.jpeg ne.jpg izixhumanisi ziyi-bitstream efanayo, ngakho akukho okuthile lapha okuzosebenza ngokuhlukile ku-.jpg — igama lefayela kuphela elishintshayo. Kufanele ulinde isikhathi ngaphambi kokugxila kulokho ongakukwazi ukukwenza kabusha.

Ingabe ngingakwazi ukushintsha amafayela amaningi 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.

Ingabe i Flip JPEG ibonisa kanjani ifayela?

Ngokucacile, isithombe esihamba phambili noma esihamba phambili siyi-lossless DCT transform, ngakho ihele libhala kabusha ngaphandle kokuqokwa futhi liphinde liqokwe isithombe ngaso sonke isikhathi — i-output ifana ne-pixel ku-original eqokwa. Ukhetha umgwaqo — ohamba phambili ukhiqiza isithombe se-mirror, ohamba phambili ukhiqiza ukubukeka okuphezulu-phansi — futhi ihele lonke liguqulwa kulo.

Yini ushintsho phakathi kokushintsha nokujikeleza?

Ukulungiswa kuguqula okuqukethwe ngapha kwe-axis futhi kukhiqiza isithombe se-mirror; ukujikeleza kuguqula ngaphandle kokushintsha noma yini. Umbhalo unikeza: ufunda emuva ngemuva kokulungiswa futhi uhlala ufundeka ngemuva kokulungiswa.

Ingabe Flip JPEG ibiza noma yini?

Yini ekwenzeke ku-EXIF nedatha yeprofayili yombala?

Kuxhomekeka kwithuluzi. Ukucindezela kususa i-EXIF kanye neprofayili yombala ofakwe ngaphakathi ukuze ugcine indawo, ngenkathi ukuhlela njengenguqulo yosayizi noma ukujikeleza kungagcina. Akukho sinqumo kulekhasi lokukhetha, ngakho hlola ifayela ngombonisi wedatha yemeta ngaphambi kokuyishicilela uma idatha yendawo ibalulekile.

Kungani i MP3 site i host Flip JPEG?

MP3.to ifakwe ngaphansi kwefomethi eyenza umsindo ophathekayo ojwayelekile: odlalayo emhlabeni wonke, omncane ngokwanele ukukhohlwa, nolahlekile ngendlela ebalulekile uma uqhubeka nokuphinda uyikhode. Uhlu lwemisebenzi yomsindo: umuntu ofanayo odinga ifomu elisha uvame ukudinga ihele elicushiwe, elihlanganiswayo noma elincane eqenjini elifanayo. Ukubeka Flip JPEG ngemuva kokufaka okufanayo, amacaps afanayo ne-akhawunti efanayo yilokho okushintsha ama-tabs amathathu abe eyodwa.

Yini okufanele ngiyenze ngemiphumela uma i Flip JPEG iqediwe?

Ingabe Flip JPEG lapha ithuluzi elifanayo lezindawo ezifanayo ezisebenza?

Ama-engine ahlukaniswe - i-ffmpeg efana ne-build, abasebenza nabo, ama-limits afana. Okushiwo yi-MP3 site kuyinkomba ye-bitrates, mayelana nokuthi yini egcina i-encoding kanye nokuthi yikuphi lapho i-lossless intermediate ifanele uku-upload isikhathi. Kuqala futhi kusuka kuqiniso elinye mayelana nefomethi le site ibizwa ngemuva: Amafreyimu we-MP3 ayizingxenye ezincane eziqinile, ngakho ukucisha kuwela emgwaqweni wefreyimu futhi ama-gapless playback markers angeke aphile uma kuphinde ku-code.
