TIFF kuya PDF Imibuzo Evame Ukubuzwa Yokuguqulwa

Ngiguqula kanjani i-TIFF ibe yi-PDF ukuwabelana noma ukuphrinta?

Layisha phezulu ihele TIFF futhi umguquli uyenza ibe yi PDF amakhasi ngephutha elifanele: A4 / ubukhulu be-letter, 1-intshi ama-margins, amafonti afakwe ngaphakathi. Ama-multi-page sources (DOCX, EPUB, XLSX) agcina ama-page breaks abo ajwayelekile; ama-single-assets sources (izithombe) athola ikhasi elinye ngalinye, alungele ngokuzenzakalela ikhasi. I-TIFF iyifomethi yefayela lesithombe ephawulwe kusukela ngo-1986, futhi iyifomethi yokuskena, ukushicilela kanye nokugcinwa kwezinto eziphilayo ezijwayelekile. PDF yi Adobe's Portable Document Format kusukela ngo-1993, ejwayelekile njenge ISO 32000 futhi manje yidokhumende eliphelele eliqinile-lohlelo.

Yini uma umsuka u-scan ngaphandle kobhalo osemthethweni?

Ngakho-ke ukuguqulwa kuletha isithombe sombhalo endaweni yombhalo, futhi ukubhekana nakho akutholakali. Sebenzisa /pdf-ocr/ ukungeza i-layer yombhalo oyaziwayo kuqala; ukuphawula kophawu olubonakalayo luguqula ama-pixels axhunywe ku-ekhethiwe, ama-characters atholakali ukuthi ukuguqulwa kungathatha ngokufanele.

Ingabe i-PDF izovulwa ngokuqondile kumsakazi?

Yebo, futhi i-TIFF ayikwazi. Amasiphequluli athumela umbhalo oguqulwe nge-PDF futhi akukho ku-TIFF, ngakho-ke i-TIFF ixhunywe ngokucindezela ukulayisha phansi ngenkathi i-PDF ibonisa umbhalo ongezansi. Lokhu kuvame ukube yisimo esibalulekile lapho ihele lihamba kwikhasi le-web ngaphezu kokungenisa isicelo. I-PDF ibukeka ifana nge-byte-by-byte kunoma iyiphi imishini nanoma iyiphi iphrinta, ngakho-ke amakontraka, amafayela nama-papers amakhono wonke ahlala kuyo.

Yini ekwenzeke kuma-area abonisa ngale TIFF wami ku-PDF?

Zihlanganiswe ngekhasi, elimhlophe ngokuzenzakalela, ngakho isizinda esicacile sizoba mhlophe. Uma isithombe sidinga ukuhlala kwikhasi elimnyama, hlela umbala omnyama ngaphambi kokuguqula, kungakhathaliseki ukuthi uzama ukuwulungisa ngemuva kulolu hlelo.

Ingabe ikhamera nendawo yedatha yemeta ifakwe ku PDF?

EXIF ihamba nedatha yesithombe esifakwe, okusho ukuthi ama-GPS coordinates angaphela ngaphakathi kwedokhumende ofuna ukushicilela. Sebenzisa ukhetho lwe-strip-metadata ngesikhathi sokuguqulwa uma i PDF ihamba nganoma yikuphi omphakathi — uma ifakwe akuyona into ecacile ukuthi ikhona.

Ingabe i-PDF yengxenye yokuguqulwa ingase ifuneke?

Kuxhomekeka ngokuphelele ukuthi umbhalo ongokoqobo ukhona noma cha. I-PDF eyenziwe kusuka kudokhumende ifaka umbhalo ongokoqobo futhi itholakale; i-PDF eyenziwe kusuka ku-scans noma izithombe yisithombe sombhalo futhi ayinjalo, kuze kube i-OCR ifaka umbhalo. /pdf-ocr/ yenza lokho, futhi kufanelekile ukuqhuba ngaphambi kokuguqulwa okulindeleke ukufundwa kwegama.

Ingabe ukuguqulwa TIFF kuya ku PDF kuzogcina ifonti yami nohlelo?

Yebo ku-text-bearing TIFF (DOCX, ODT, HTML, TXT) — amafonti afakwe ku-PDF ukuze i-output ibonakale ifana kunoma iyiphi imboniso. Isithombe- kuphela TIFF (JPG, PNG) ifaka isithombe engxenyeni; isitayela siyi-N/A.

Ingabe ngingakwazi ukuxhuma amafayela amaningi TIFF ku PDF?

Yebo — susa amafayela amaningi TIFF endaweni yokulayisha futhi ukhethe "ukuhlanganisa ku PDF" ukhetho. Zivela njengekhasi elilandelanayo ku PDF ngokulandelana kokulayisha; ukudonsa-ukuhlela kabusha kuxhaswa ngaphambi kokuguqulwa. Kusetshenziswa ukuxhuma isibaya sezinqumo ku-PDF ingobo yomlando eyodwa.

Yini usayizi wekhasi kanye nobubanzi obusetshenziswa yi PDF?

Iphutha: A4 isithombe esigcwele (isizwe) noma isithombe se-letter (US). Izinketho ezithuthukisiwe zibonisa ubukhulu bekhasi (A3, A4, A5, isithombe, imithetho, i-tabloid, okujwayelekile) kanye nobubanzi (ububanzi / ububanzi). Isithombe TIFF, "ukulungele-ngokuzenzakalela" ukhetho lukhetha ububanzi ukuze ulinganise nesilinganiso somthombo.

Ingabe ama-hyperlinks e TIFF angizophila ngokuguqulwa kwe PDF?

Yebo ku TIFF amafomethi aphathe i-hyperlink metadata (DOCX, ODT, HTML, EPUB). Isithombe esisekelwe ku TIFF (JPG, PNG, TIFF) asikho i-hyperlink esigcinwa. Ihele PDF lisebenzisa imodeli ye-PDF ejwayelekile ukuze ama-link asebenze kuwo wonke umfundi (Acrobat, Preview, Chrome, Edge).

Ingabe i-PDF ingase ifuneke ngetekisi ekhethiwe?

Yebo uma i TIFF iqukethe ama-layers ombhalo ongempela (DOCX, ODT, HTML, TXT, EPUB). Isithombe-sisekelwe ku TIFF sikhiqiza isithombe-sokuphela PDF — ukuze kwenzeke ukuthi sitholakale, landela nge /pdf-ocr/ ukuqhuba ukuphawula okubonakalayo kwegama phezu kwekhasi le-bundle. 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 ngigcina i-PDF ngephasiwedi ngemuva kokuguqulwa?

Akunalesi simo esifanayo — guqula TIFF ku PDF kuqala, bese usebenzisa /pdf-protect/ ukufaka iphasiwedi evulekile, iphasiwedi yomnikazi, noma uphrinta / hlela izimo ezivimbelayo. Ukuhlukanisa izimo kwenza ukuthi isiguquko ngasinye sihlale sibhekene futhi sisheshe.

TIFF

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

PDF

Amafayela e-PDF agcina ukufometha kuwo wonke amadivayisi nezinhlelo zokusebenza, okwenza kube kuhle ukwabelana ngamadokhumenti okudingeka abukeke afana yonke indawo.
