WebP kuya TIFF Imibuzo Evame Ukubuzwa Yokuguqulwa

Ngiguqula kanjani i-WebP ibe yi-TIFF ngaphandle kokulahlekelwa ubuhle besithombe?

Layisha phezulu ihele lakho WebP futhi umguquli ufaka ukulungisa umgangatho okwaziyo ifomethi ye TIFF. U TIFF ongalahleki (PNG, TIFF, BMP) wonke ama-pixel agcinwa; u TIFF ongelahleki (JPG, WebP) ungahlela umphumela womgangatho ngaphambi kokufaka ngezansi. I-WebP inikeza izimo ezilahlekile nezingenalahlekile, ngokukhanya kwe-alpha nokubukeka okutholakalayo kunoma yikuphi. I-TIFF iyindawo yokuqoqa engaphezu kwe-codec: ingagcina idatha engacindezelwanga, i-LZW, i-ZIP noma i-JPEG, kuze kube yi-32 bits ngasinye, ngekhasi eliningi kwifayela elilodwa.

Ingabe ukushintsha WebP kuya ku TIFF kuzobuyisela ubunjani obulahlekile?

Akukho. Izinto ezicindezelwe ezifakwe ku WebP manje ziyidatha ye-pixel ejwayelekile, futhi TIFF igcina kahle kunesisusa. Ihele livame ukukhula, ngamanye amaxesha likhula izikhathi eziningi. Kuyinto efanele ukuyenza ngaphambi kokuhlela, ngoba ukuhlela okulandelayo akuzofaka isizukulwane sesithathu sokulimala phezulu. I-TIFF iphatha i-CMYK, 16-bit ububanzi, i-ICC ifaka amaprofayili namadokhumende amakhasi amaningi, okuwukuthi okuthile okudingekayo ukuphrinta nokugcinwa kwemisebenzi. I-WebP ihlala iyisikole sesithathu ngaphandle kwesiphequluli — ukuphrinta komsebenzi, ama-Office adala futhi ezinye izimboni zefoni azikwazi ukuwuvuma.

Ingabe i-TIFF igcina i-EXIF data kusuka ku-WebP yami?

Ngokungajwayelekile yebo, lapho injongo ikhona khona ukuze ibekwe khona - imodeli yekhamera, izilungiselelo zokuveza, ilensi kanye ne-GPS coordinates zonke zihamba phambili. I-GPS iyindawo efanele ukucabanga ngayo: uma isithombe sizoshicilelwa, sebenzisa i-strip-metadata option ukuze ungasakazi lapho isithombe sithathwe khona. WebP Google 2010 isithombe ifomu, eyenziwe kusuka VP8 keyframe encoder futhi inhloso ukushintsha JPG, PNG ne GIF ngasikhathi sinye.

I WebP yami iphila — yini ekwenzeke kwezinye ifreyimu?

Ifreyimu yokuqala kuphela ehlala, ngoba TIFF iyifomethi ehlala khona engenandawo yokugcina okushiwo. Uma udwebo lubalulekile, bheka ifomethi edlalayo, noma uguqule ibe yividiyo equkethe isithombe futhi ugcine ukunyakaza. Ukulungelelaniswa kwe-TIFF kuyinkinga yayo - ama-TIFF amabili angakhiwa ngendlela ehlukile yokuthi isofthiwe efunda enye iphutha kwezinye - futhi amafayela akhulu.

Ingabe ukuguqulwa WebP kuya ku TIFF kugcina ukubukeka okucacile?

Ukubukeka okucacile kuhlala lapho TIFF i-PNG, WebP, TIFF, GIF, noma i-SVG. Ukushintsha ku-JPG kuhlanganiswa isixhumi se-alpha esibhekene nesizinda esimhlophe. Uma ufuna ukubukeka okucacile esinqumweni, bheka ukubonakala okucacile okuqaphelayo TIFF endaweni ye TIFF=JPG. I-TIFF iyifomethi yefayela lesithombe ephawulwe kusukela ngo-1986, futhi iyifomethi yokuskena, ukushicilela kanye nokugcinwa kwezinto eziphilayo ezijwayelekile.

Ingabe iprofayili yami yombala (sRGB / Adobe RGB / CMYK) izohlala i WebP kuya ku TIFF?

Amaprofayili wemibala we-ICC afakwe ngaphakathi afundwa kusuka ku-WebP futhi axhunywe kabusha ku-TIFF lapho ifomethi ixhasa khona (JPG, PNG, TIFF, WebP). Amafomethi ngaphandle kwe-inkxaso yeprofayili abuyela emuva ku-sRGB, ogcina amamibala ahambisanayo phakathi kweziboniso eziningi ezimanje.

Yini mayelana ne-EXIF metadata uma uguqula WebP usuka ku-TIFF?

Ikhamera EXIF (ISO, i-shutter, i-lens, i-GPS coords) igcinwa ngokuzenzakalela ngesikhathi WebP → TIFF lapho amafomethi amabili exhasa i-metadata. Sebenzisa ukhetho lokufihla ukususa i-metadata ngaphambi kokulayisha ngezansi uma ufuna ukuhlanganisa izithombe ngaphandle kokubeka indawo.

Ingabe ngingenza ukuguqulwa kwe-batch kwe-WebP amafayela amaningi ku-TIFF ngasikhathi sinye?

Yebo — cindezela amafayela amaningi WebP endaweni yokulayisha futhi sizowabeka emqoka ngokufanayo. Abasebenzisi abamahhala bathola i-100 MB ngefayela ngalinye; iPremium ayinaso isiphetho sefayela ngalinye futhi isebenza nabasebenza ngokufanayo, ngakho-ke isithombe esingu-200 siqediwe ngaphantsi kwemizuzu emibini.

Ingabe WebP kuya ku TIFF iqhathaniswa kanjani ne-Photoshop / GIMP ngemisebenzi efanayo?

Ukuguqulwa kwefomethi eqondile sisebenzisa i-libpng / libjpeg-turbo / libwebp / ImageMagick pipes efanayo umhleli wedesktop asebenzisayo, ngekhwalithi yokuphuma efanayo. Ushintsho luyi-batch management ehambisanayo — ama-desktop apps avula ifayela elinye ngasikhathi sinye; sivuma i-batch.

Yini isixazululo sehele lami TIFF?

Iphutha ngu 1:1 — TIFF yakho igcina ama-pixels ama-dimensions we-WebP. Uma ufuna ukushintsha ubukhulu njengengxenye yokuguqulwa, sebenzisa /resize-image/ ngemuva kokuguqulwa, noma uyibeke nge /image-resize/ utility.

Ingabe i TIFF ingaba ncane ngaphandle kwezinto ezibonakalayo ezibonakalayo?

Nge-JPG / WebP, umgangatho 75-85 uvame ukuthola i-TIFF 60-80% encane kuna-WebP ngaphandle koshintsho olubonakalayo emgwaqweni wokubuka ojwayelekile. Nge-lossless TIFF (PNG, TIFF), cabanga ukulondoloza okuncane — ngokuvamile 5-30% nge-deflate / LZW yokucindezela okungcono.

Ingabe amafayela ami WebP afihlakele ngesikhathi sokuguqulwa?

Yebo — amafayela alayishwe phezulu WebP aqhubekelwa phambili emisebenzini ehlukanisiwe futhi acishwe ngaphakathi kwemizuzu. Asikwazi ukufunda, ukugcina isikhathi eside, noma ukuhlanganisa idatha ye-pixel. Ifasitela eligcwele lokugcinwa libhalwe ku /privacy/.

WebP

I-WebP inikeza ukucindezela okungcono kakhulu okungenakulahlekelwa nokungalahleki kwezithombe eziku-inthanethi, okwakhiwe yi-Google.

TIFF

Amafayela e-TIFF asekela ukujula kwe-bit ephezulu kanye nokucindezelwa okungenakulahlekelwa, okulungele ukuthwebula izithombe zobungcweti kanye nokuphrinta.
