Indlela yokujikelezisa WebP

1 Layisha phezulu i WebP 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 WebP.

Jikelezisa WebP Imibuzo Evame Ukubuzwa

Indlela eJikelezisa WebP 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 ngizojikelezisa nge-engile ehlukile, hhayi ama-degrees angama-90 kuphela?

Yebo, kepha lezi ezimbili zisebenza ngokuhlukile ngaphansi. Ukuphindaphinda kwamadigri angama-90 kuhlela kabusha idatha ekhona; noma yisiphi isikhala sidinga ukubuyisela i-grid futhi sigcwalise amakhonsoli, ngakho kubiza ukusatshalaliswa futhi kuvame ukudinga umbala wesizinda wokukhetha.

Ingabe ifomu lisho ukuthi ngabe ukujikeleza kungeke kulahleke?

Isebenza. I-WebP ithatha zombili indlela ye-VP8 elahlekile kanye nendlela engalahleki kanye ne-alpha egcwele, ngokuvamile ifinyelela ku-25-35% ngaphansi kwe-JPG ehambisanayo nekhwalithi yokubuka. Le mpahla ilungile ngoba ichaza ukuthi ngabe isigamu sosuku sikhululekile noma izindleko ziphinde zikhodwe.

Ingabe kukhona okuthile okukhethekile ku WebP okufanele ngikwazi?

Yebo — i-.webp efana nengxenye ingagcina i-VP8 elahlekile, elahlekile, noma i-animated, ngakho-ke indlela yokucubungula efanele isinqunywe ngefayela ngalinye ngaphezu kwengxenye ngayinye. 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.

Ingabe ngizojikelezisa iqembu lonke ngasikhathi sinye?

Yebo. Ujikelezo olufanayo lusetshenziswa kuwo wonke amafayela olayishe, okuwusizo olukhulu lokuxazulula ifolda yezinqumo noma ikhamera ephumayo, konke okuvela ngendlela engalungile.

Yini engikwazi ukuyifaka ku Jikelezisa WebP?

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 isizukulwane, ngakho isithombe esigcinwe nge-suffix engalungile sizoqhubeka sihamba.

Ingabe kunesilinganiselo sobukhulu behele ku Jikelezisa WebP?

Yebo: ama-akhawunti amahhala asebenza ngezithombe kuze kube yi-25 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 WebP izonciphisa ukhwalithi ye WebP 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.

Ingabe ngizosebenzisa Jikelezisa WebP ku WebP 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.
