BMP kuya PDF Imibuzo Evame Ukubuzwa Yokuguqulwa

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

Layisha phezulu i BMP 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, XLSX) agcina ama-page breaks; ama-single-assets sources (izithombe) athola ikhasi elinye ngalinye.

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 ngokulungile.

Ingabe i-PDF izovulwa ngokuqondile kumsakazi?

Yebo, futhi i-BMP ayikwazi. Amasiphequluli athumela umbhalo oguqulwe nge-PDF futhi akukho ku-BMP, ngakho-ke i-BMP ixhumana nokukhuphula uma 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.

Kungani i BMP yami ikhulu kakhulu kuna PDF ekugcineni?

Ngenxa yokuthi BMP igcina idatha yayo ye-pixel encane noma encane kakhulu — lokhu kwenza kube yifomethi esebenza kahle ngaphezu kokunikeza enye — futhi idokhumende aligcinanga ngendlela efanayo. Isithombe siphinde sikhonjiswa kabusha kufomu elicindezelwe lapho libekwa khona, ngakho-ke umsuka we-megabytes ayi-30 ungawela njengesithombe se-megabytes amabili ngaphandle koshintsho olubonakalayo ekufundeni ubukhulu. Lokhu kulondoloza ngaphezu kokulahleka kwanoma yini ehlobene neskrini. Uma idokhumende liya kuphrinta, phakamisa umgangatho wokufaka ngaphambi kokuguqula ngaphezu kokuzama ukubuyisa iminingwane ngemuva. I-BMP iyinto enkulu—isithombe esingu-12-megapixel siyizi-36 MB—nakho akukho isiphequluli esiyiphatha njengefomethi yewebhu efanele.

Ngingayivimbela kanjani izithombe-skrini ezibukeka zilula uma zikhona ku PDF?

Gcina kubukhulu babo be-pixel. A BMP yilokho okugcinwa njengesithombe esithathwe ku-screenshot, futhi umbhalo we-screenshot udwetshwa nge-pixel eyodwa encane - yenza ukuphakama noma ukuwa ngaphakathi kwedokhumende futhi izifomethi zesibhalo zimnyama ngokushesha, ngoba akukho lutho oluzophinde luthathwe. Faka isithombe kubukhulu obugcwele futhi ushintshe ukujula kwekhasi endaweni; uma ngempela kufanele kube ncane, phinda uthathe ifasitela kubukhulu obuncane ngaphezu kokuncipha kwesithombe ngemuva. I-BMP ayidingi i-decoder library ngaso sonke isikhathi, ngakho ihlala i-format ephephile yokushintshana yezinhlelo ezifakwe ngaphakathi neWindows ezidala.

Ingabe i-PDF yengxenye yokuguqulwa ingase ihlolwe?

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 BMP kuya ku PDF kuzogcina ifonti yami nohlelo?

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

Ingabe ngingakwazi ukuxhuma amafayela amaningi BMP ku PDF?

Yebo — susa amafayela amaningi BMP endaweni yokulayisha bese ukhetha "ukuhlanganisa ku PDF" ukhetho. Zivela njengekhasi elilandelanayo ku PDF ngohlelo lokulayisha; ukudonsa-ukuhlela kabusha kuxhaswa ngaphambi kokuguqulwa.

Ingabe ikhasi le PDF lisebenzisa usayizi kanye nobubanzi?

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 BMP, "ukulungele-ngokuzenzakalela" sikhetha ububanzi ukuze sifane nesimo sendawo yomthombo.

Ingabe ama-hyperlinks e BMP angizophila ngokuguqulwa kwe PDF?

Yebo ku BMP amafomethi ane-hyperlink metadata (DOCX, ODT, HTML). Isithombe esisekelwe ku BMP (JPG, PNG, TIFF) asikho i-hyperlink esigcinwa. Ihele PDF lisebenzisa izenzo ze-PDF URL ezijwayelekile ukuze ama-hyperlinks asebenze kuwo wonke umfundi we-PDF.

Ingabe i-PDF ingase ihlolwe (umbhalo okhethiwe)?

Yebo uma i BMP iqukethe umbhalo osemthethweni (DOCX, ODT, HTML, TXT). Isithombe-sisekelwe ku BMP sikhiqiza isithombe-sokuphela PDF — ukuze sikwazi ukusesha, sebenzisa /pdf-ocr/ ngemuva kokuguqulwa ukuze uqhube ukuphawula okubonakalayo kwegama.

Ingabe ngigcina i-PDF ngephasiwedi ngemuva kokuguqulwa?

Akunalesi sisetshenziswa — guqula BMP ku PDF kuqala, bese usebenzisa /pdf-protect/ ukufaka igama lokungena, i-watermark, noma ugweme ukuhlela. Ukuhlukanisa imisebenzi kwenza kube lula ukuguqula kabusha ngaphandle kokushaya kabusha igama lokungena.

BMP

Amafayela e-BMP agcina izithombe ngefomethi ye-bitmap engacindezelwanga, okuholela osayizi bamafayela abakhulu kodwa ikhwalithi ephelele.

PDF

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