TIFF ukuba PNG Imibuzo Ebuzwa Rhoqo Ngokuguqula

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

Layisha phezulu ifayili yakho ye TIFF kwaye umguquli wethu usebenzise ukuphuculwa komgangatho owaziyo ifomati ye PNG imveliso. Kwiinjongo ezingalahlekiyo (PNG, TIFF, BMP) yonke i-pixel igcinwa nge-bit-per-bit; kwiinjongo ezilahlekiyo (JPG, WebP) ungalungisa isizathu somgangatho (okungagqibekanga 90) 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 kwifayile enye. I-PNG isebenzisa uxinzelelo lwe-DEFLATE ngaphezulu kwamagqabantshintshi okuskena acociweyo, ngoko ke i-pixel nganye ihlala ngokuchanekileyo, kunye ne-8-bit epheleleyo ye-alpha channel.

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 PNG ayinaso isakhiwo sokuba zigcine. Gcina i TIFF njenge-master esebenza kakuhle kwaye uthathe i PNG ngokungqongqo njenge-export. I-TIFF iphatha i CMYK, ubunzulu be-16-bit, i-ICC efakwe ngaphakathi kunye namaxwebhu ephepha elininzi, eli linyaniso le shicilelo kunye nomsebenzi wokuhamba kovimba ofunayo. I-PNG yifomati yomfanekiso ophantsi: umfanekiso ogciniweyo njenge-PNG uhlala ukhulu ngeeyure ezisixhenxe ukuya kwezilishumi kunemifanekiso efanayo njenge-JPG okanye i-WebP.

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

Iguqulwe kwi sRGB, kuba PNG 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 PNG.

Ingaba i PNG 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 ophawulwe ukusukela ngo-1986, kwaye yifomati yokukhangela, yoshicilelo kunye nokugcina iinjineli ezimiselwe.

Ingaba kukho into elahlekile ekuguquleni phakathi kwe TIFF ne PNG?

Akukho data yepixel, hayi. Zonke iifomati zigcina umfanekiso ngaphandle koxinzelelo olulahlekileyo, ngoko ke umfanekiso ophumayo ufana nowo waya ngaphakathi kwaye uguqulelo luyaphinda uphinde luphinde. Okutshintshayo kubungakanani befayili, kwaye oku kusebenza ukuhamba - ubunzulu bombala, iiprofayili ezifakelweyo, amanqanaba noopopayi bonke baxhaswa ngokungalinganiyo phakathi kwefomati ezingalahlekileyo.

Ingaba uguqulelo TIFF ukuya ku PNG lugcina ukubonakala ngaphaya?

Ukubonakala ngaphaya kuqhubeka xa PNG yi-PNG, WebP, TIFF, GIF, okanye SVG. Ukutshintsha ukuba yi-JPG kwenza ukuba isiqhagamshelanisi se-alpha sifane nesiqalo esimhlophe — ukuba ufuna ukubonakala ngaphaya, khetha isiphelo esizimelayo esibonisa ngaphaya endaweni ye-PNG. I-PNG yaphuhliswa ngowe-1996 njengento engekhoyo kwipateni ye-GIF, kwaye yayiyifomati yomfanekiso ongekhoyo kwi-web.

Ingaba i-inkangeleko yam yombala (sRGB / Adobe RGB / CMYK) iya kuhlala i TIFF ukuya ku PNG?

Iiprofayili zombala we-ICC ezifakelweyo zifundwa kumvelaphi TIFF kwaye zidityaniswe kwakhona kwi-PNG yemveliso apho ifomati ixhasa khona (JPG, PNG, TIFF, WebP). Iifomati ezingaxhaswanga yiprofayili zibuyela kwi-sRGB ngenyathelo elilula lokuqinisekiswa.

Ithini into ebangela ukuba i-EXIF metadata iguqulwe TIFF ibe yi PNG?

I-EXIF yekhamera (ISO, i-shutter, i-lens, i-GPS) igcinwa ngokumiselweyo ngexesha TIFF -> PNG xa zombini iifayili zixhasa i-metadata. Sebenzisa utshintshi lobumfihlo ukususa i-metadata phambi kokukhuphela ukuba ufuna ukuthumela imifanekiso ngaphandle kokubekwa kwendawo okanye ukubonisa umnwe wesixhobo.

Ndingaguqula izigidi zeefayili TIFF zibe PNG ngaxeshanye?

Ewe - rhuqa iifayile ezininzi TIFF kwindawo yokulayisha kwaye zifolole ngokuthe tye. Umphakamo osimahla uyamkela i-100 MB ngefayili nganye; i-Premium ayinasiphelo sefayili nganye kwaye iqhuba abasebenzi abathe tye abaninzi, ngoko ke iqela lemifanekiso engama-200 ligqiba ngaphantsi kwemizuzu emibini.

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

Uguqulelo lwefomati olulula siqhuba i libpng / libjpeg- turbo / libwebp / ImageMagick imibhobho efanayo umhleli we desktop asebenzisayo, kwi umgangatho ofanayo. Utshintsho kukuba izixhobo ze desktop zivula ifayile enye ngexesha; siyamkela iqela kwaye siqhuba ngokuthe tye kwiseva- ecaleni kwabasebenzayo.

I-PNG iifayili zinee-resolutions kunye nemilinganiselo eziphi?

Ukuziphatha okungagqibekanga kuku 1:1 — i-PNG yakho yemveliso inezinto ezilinganayo ze-pixels njenge-TIFF. Ukuba ufuna ukuguqula ubungakanani njengenxalenye yokuguqula, sebenzisa /resize-image/ emva, okanye ubeke iinzame kwi- /image-pipeline/ utility.

Ingaba i PNG ifayili incinane kangakanani na ukuba ayinazo izinto ezibonakalayo ezibonakalayo?

Kwi-JPG / WebP, umgangatho we-75-85 uhlala uvelisa i-PNG 60-80% encinci kune-TIFF ngaphandle kotshintsho olubonakalayo kumgama wokujonga oqhelekileyo. Kwi-PNG engenanto (PNG, TIFF), lindele ukonga okuncinci — ngokuqhelekileyo 5-30% nge-deflate / LZW yokucinezela engcono kuneleyo umboneleli sele uneyo. I-PNG yinketho efanelekileyo yokuthatha imifanekiso yekhusi, ilogos, umzobo womgca nantoni na enemiphetho eqinileyo okanye ebonisa ngaphaya — akukho cingo, akukho mbala obandayo.

TIFF

Iifayile zeTIFF zixhasa ubunzulu be-bit ephezulu kunye noxinzelelo olungenalahleko, zilungele ukufota kunye nokuprinta ngobuchwephesha.

PNG

Iifayili ze-PNG ziqhubekeka ngokucacileyo kwaye zisebenzisa ukucinezela okungalahleki, zenza ukuba zilungele amagrafiki, ilogos, kunye nemifanekiso yekhusi.
