TIFF ukuba WebP Imibuzo Ebuzwa Rhoqo Ngokuguqula

Ndiyiguqula njani i-TIFF ibe yi-WebP ngaphandle kokulahlekelwa umgangatho womfanekiso?

Layisha phezulu ifayile yakho TIFF kwaye umguquli usebenzise umgangatho owaziyo wefomati efanelekileyo ye WebP. Ukungabikho kolahleko WebP (PNG, TIFF, BMP) yonke ipixel igcinwa; ukungabikho kolahleko WebP (JPG, WebP) ungalungisa umgangatho womsebenzi phambi kokukhuphela. I-TIFF yindawo yokugcina engaphezulu kwe-codec: inokuphatha i-data engacinezelwanga, i-LZW, i-ZIP okanye nakwi-JPEG, ukuya kuthi ga kwi-32 bits kwisiqhagamshelanisi ngasinye, ngeephepha ezininzi kwifayili enye. I-WebP inikezela zombini iimeko ezilahlekileyo nezingalahlekileyo, ngokubonisa ngokucacileyo kwe-alpha noopopayi abafumanekayo kumnye.

Ithini into eyenza amanqanaba efayili yam TIFF?

Ziqhotyoshelweyo, ngokusisigxina, kumfanekiso omnye odityanisiweyo. Iinkqubo zokudibanisa, iziqhoboshi, amanqanaba olungiso kunye nombhalo ohlelayo zonke zilungiswe kwipixels yokugqibela kuba WebP ayinaso isakhiwo sokuba zigcine. Gcina i TIFF njenge-master esebenza kakuhle kwaye uthathe i WebP ngokungqongqo njenge-export. I-TIFF iphatha i CMYK, ubunzulu be-16-bit, i-ICC efakwe ngaphakathi kunye namaxwebhu amaphepha amaninzi, eyona nto ishicilela kwaye ifuna uthungelwano lomsebenzi wokugcina. I-WebP ihlala ikwinqanaba lesithathu ngaphandle komkhangeli zincwadi — ushicilelo lokuhamba komsebenzi, i-Office edala i-Office edala i-Office kunye nezinye ii-galeri zefowuni aziyi kuxhaswa.

Ingaba ndiya kulahlekelwa yintoni ngomgangatho xa ndisuka kwi TIFF ukuya kwi WebP?

Kwi umgangatho 80- 85 utshintsho alubonakali kumgama wokubona oqhelekileyo kwaye ifayile ihlala iphantsi nge 60- 80%. Ukubamba kukuba yindlela enye: ukubuyisela ukugcina i WebP ngokuphindaphinda idibanisa i artefacts ixesha ngalinye. Gcina i TIFF njenge master kwaye uphinde uphinde uvule i WebP ukusuka kuyo xa ufuna ubungakanani obutsha.

Ingaba umbala wam we-CMYK uya kuqhubeka nokuguqulwa kwi WebP?

Iguqulwe kwi sRGB, kuba WebP ayinayo i CMYK indlela. Ukusetyenziswa kwesikrini oku kulungile. Ushicilelo lweshishini akusebenzi - utshintsho lwegama lokutshintsha indlela imibala ethambileyo ephindayo kwiqhosha, ngoko thumela umshicileli okuqala TIFF endaweni ye WebP.

Ingaba i WebP igcina i-EXIF data evela kum TIFF?

Ngokungagqibekanga ewe, apho naphi na apho injongo ifuna ukubekwa khona - imodeli yekhamera, izicwangciso zokubonisa, iinwele kunye neGPS ikhowudi zihamba zonke. I-GPS yindawo efanele ucinga ngayo: ukuba umfanekiso uzakupapashwa, sebenzisa ukhetho lwe-strip-metadata ukuze ungasazibonisi apho umfanekiso uthathwe khona. I-TIFF yifomati yefayili yomfanekiso ophawulweyo ukusukela ngo-1986, kwaye yifomati yokukhangela, yoshicilelo kunye nokugcina iinjineli ezimiselwe.

Ingaba uguqulelo TIFF ukuya WebP lugcina ukubonakala?

Ukubonakala ngaphaya kuqhubeka xa WebP i-PNG, WebP, TIFF, GIF, okanye SVG. Ukutshintsha kwi-JPG kugubungela isiqhagamshelanisi se-alpha phantsi kokungasemva omhlophe. Ukuba ufuna ukubonakala ngaphaya kwiziphumo, cwangcisa ukubonakala ngaphaya okuziyo WebP endaweni ye-WebP=JPG. I-WebP yifomati yomfanekiso yeGoogle ka-2010, eyenziwe kwi-VP8 keyframe encoder kwaye imiselwe ukubuyisela i-JPG, i-PNG ne-GIF ngaxeshanye.

Ingaba iprofayili yam yombala (sRGB / Adobe RGB / CMYK) izakuhlala i TIFF ukuya ku WebP?

Iiprofayili zombala we-ICC ezifakwe ngaphakathi zifundwa ukusuka kwi TIFF kwaye zidityaniswe kwakhona kwi-WebP apho ifomati ixhasa khona (JPG, PNG, TIFF, WebP). Iifomati ezingaxhaswanga zibuyela kwi-sRGB, egcina imibala ihambelana nakwimboniselo eninzi yexesha elidlulileyo.

Yintoni malunga ne-EXIF metadata xa uguqula TIFF ukuya WebP?

I-EXIF yekhamera (ISO, i-shutter, i-lens, i-GPS coords) igcinwa ngokumiselweyo ngexesha TIFF → WebP xa zombini iifayili zixhasa i-metadata. Sebenzisa ukhetho lobumfihlo ukususa i-metadata phambi kokukhuphela ukuba ufuna ukuthumela imifanekiso ngaphandle kolwazi lwendawo.

Ndingaguqula iifayili ezininzi TIFF zibe WebP ngaxeshanye?

Ewe - tsala iifayile ezininzi TIFF kummandla wokulayisha kwaye sizibeke kwifolokhwe ngokuthe ngqo. Abasebenzisi abakhululekileyo bafumana i-100 MB kwifayili nganye; iPremium ayinalo icebo kwifayili nganye kwaye iqhuba abasebenzi abathe ngqo, ngoko ke umfanekiso we-200-iqela ligqiba ngaphantsi kwemizuzu emibini.

I-TIFF ithelekiswa njani ne-WebP kwi-Photoshop / i-GIMP kumsebenzi ofanayo?

Uguqulelo lwefomati ethe ngqo siqhuba i libpng / libjpeg- turbo / libwebp / ImageMagick imijelo yomhleli we desktop osebenzisa, ngemveliso efanayo yobunjani. Utshintsho luhamba ngaphaya kolawulo lweqela - iinkqubo ze desktop zivula ifayile enye ngexesha; siyamkela iqela.

Uphi ubungakanani obuzakubakho kwifayili yam WebP?

Okumiselweyo ku 1:1 — WebP wakho ugcina ubungakanani be-pixels yomthombo TIFF. Ukuba ufuna ukuguqula ubungakanani njengenxalenye yokuguqula, sebenzisa /resize-image/ emva kokuguqula, okanye uyibeke kwi- /image-resize/ utility.

Ingaba i WebP incinane kangakanani na ukuba ingabonakali i-artifacts?

Kwi-JPG / WebP, umgangatho we-75-85 ufumana WebP 60-80% omncinane kune-TIFF ngaphandle kotshintsho olubonakalayo kumgama wokujonga oqhelekileyo. Kwi-lossless WebP (PNG, TIFF), lindele ukonga okuncinci - ngokuqhelekileyo 5-30% nge-deflate / LZW uxinzelelo olungcono. I-WebP ihlala i-25-35% incinane kune-JPG elinganayo kwaye incinci kune-GIF ephilayo, enesixhaso se-browser esipheleleyo ukusukela ngo-2020.
