El PDF Iqale njengefomethi yenkampani yangasese futhi yagcina iba yizinga elijwayelekile. Okwamanje ingenye yamafomethi asetshenziswa kakhulu futhi adumile okwabelana ngemibhalo, njengoba inikeza ukuguquguquka okukhulu namathuba. Akumangalisi ukuthi isandiso se-.pdf siphakathi kwama-5 aphezulu asetshenziselwa kakhulu amafayela wombhalo njengamanje, kanye ne .doc / .docx, .odt, .txt, .tex, ne .rtf.
Kulesi siqondisi uzofunda okwengeziwe ngalezi zakhiwo nokuthi ungasebenza kanjani ngamafayela e-PDF. Imisebenzi yansuku zonke njengokucindezela, ukuhlela, ukuvikela, njll. Ngamafuphi, konke odinga ukukwazi ngaye ...
Yini i-PDF?
Kuyinto a ifomethi yesitoreji ngemibhalo eyidijithali ezimele kungxenyekazi yesoftware, ngakho-ke ingatholwa kunoma iyiphi idivayisi nomshini ohambisanayo. I-PDF yayo efushanisiwe imele i-Portable Document Format, okungukuthi, ifomethi yedokhumenti ephathekayo.

Kukhona neminye imibhalo yokuxhumana ongayigcwalisa ukuze wenze amafomu. Ngakho-ke, kunikeza ukuguquguquka okukhulu.
Yize ekuqaleni yadalwa yinkampani ezimele, ngoJulayi 1, 2008, inikezwe ukuthandwa kwayo, yakhishwa njengezinga elivulekile nangaphansi kwe-International Organisation for Standardization (ISO). I-ISO 32000-1 yiyo ehambelana nale fomethi.
Ukuthuthukiswa kwefomethi ye-PDF izoqala ngo-1991, usuku lapho ukwamukelwa kwalo kuncishiswe khona impela. Okusolwa kakhulu bekuyisidingo sesoftware ephethe amalayisense ukuze sikwazi ukusebenza nayo. Ngemuva kwalokho, ukusetshenziswa kwayo bekuzokhuphuka kuze kube yilokho okuyikho namuhla ...
Ngaphezu kwalokho, uma unikezwe ukugcinwa kwedijithali komphakathi wanamuhla, i-PDF nayo inikele gcina iphepha eliningi. Okuyizindaba ezinhle lapho kubhekene nokuqothulwa kwamahlathi ngenxa yokugawulwa kwezihlahla ukudala iphepha. Imibhalo eminingi okwabelwana ngayo ngaphambili ephepheni manje yenziwe ngokwamadijithi sibonga lo mbhalo.
Izici
I-Las izici elenze ukuthi ifomethi ye-PDF ithandwe kakhulu ingafingqwa kulawa maphuzu alandelayo:
- Ifomethi ye-Multiplatform, ngakho-ke ilusizo kakhulu ekutholeni ulwazi kubo bonke abasebenzisi.
- Ingaqukatha umbhalo ocebile onamavidiyo, imisindo, i-hypertext, amabhukumaka, izithonjana, izichasiselo, njll.
- Ifomethi ayilahlekile lapho abanye abasebenzisi bevula nge-software ehlukile, njengoba kwenzeka kwamanye amafomethi afana nama-docs, njll. Lokhu kugwema ubunzima bezinhlamvu zamafonti ukuhlelwa kabusha, ukuhanjiswa kombhalo, izici, amatafula, amafomu kagesi, njll.
- Usayizi wayo futhi uyenza ibe lusizo kakhulu kwi-Intanethi.
- Ukuba yisincazelo esivulekile, inani elikhulu lamathuluzi lingasetshenziswa ukusebenzisana nalo. Ngaphezu kwalokho, kungadalwa kusuka kumafomethi ahlukahlukene, kuguqulwe kube yi-PDF.
- Isekela izici ezithuthukile njengesiginesha yedijithali, ukuminyanisa, ama-watermark, nokubethela kokuvikelwa kwephasiwedi.
- Izinga layo lenza likulungele ukulondolozwa kwemibhalo yesikhathi eside.
- Amapulatifomu amaningi nezinhlangano ziyisebenzisa njengefomethi yesethenjwa. Isibonelo, abanye abashicileli basekela kuphela ifomethi ye-PDF yezincwadi zokuphrinta, njll.
Ukwenza konke lokhu kwenzeke, amafayela e-PDF ane- isakhiwo sangaphakathi kucace bha. Zenziwe izingxenye ezivamile kwamanye amafayela, njenge:
- Unhlokweni noma unhlokweni: yingxenye yefayela ukukhomba ukucaciswa okujwayelekile kwe-PDF nenguqulo.
- Umzimba noma umzimba: yibhlokhi lapho kuchazwa khona izinto ezisetshenziswe embhalweni, okungukuthi, okuqukethwe.
- Ithebula leCrosstab o Ithebula eliyisikhombimsebenzisi: yingxenye enolwazi mayelana nezinto ezisetshenziswe kumakhasi wefayela.
- coda noma i-trailer: lapho kukhonjiswa khona ukuthi ungayitholaphi i-crosstab.
Futhi, kufanele wazi ukuthi le mibhalo iyaxhasa inombolo enkulu yezilungiselelo, njengokukwazi ukushumeka amafonti, izethulo zombala ezihlukile (i-CMYK, i-RGB,…), ukucinana kwesithombe, njll.
Ekugcineni, futhi kufanele ucabangele enye ingxenye ebalulekile yalolu hlobo lwedokhumenti. Futhi ingabe i-PDF, njengamanye amafayela, nayo ine- imethadatha lapho kugcinwa khona inani elikhulu lemininingwane mayelana nomdali, isoftware, igama lomsebenzisi eliyidalile, usuku lokudalwa nokuguqulwa, izimfanelo zokuphepha, njll.

Lokho kubenza baphephe ikakhulukazi ekusetshenzisweni ezinhlanganweni nasemabhizinisini.
Une-software eningi ehluke kakhulu ukwazi ukukwenza konke lokho. Ukhululekile ukukhetha lowo omthanda kakhulu. Okwe-GNU / Linux kunezinhlelo zamahhala nezokuphathelene ezinhle impela.
Ingabe i-PDF ingacindezelwa?
Yebo, sengivele ngiphawule ngayo ohlwini olungenhla. Kepha akucindezeli usebenzisa ama-compression algorithms ukuguqula i-PDF ibe yi-ZIP, RAR, tarball, njll, kepha kungaba cindezela idokhumenti ye-PDF uqobo ukuyenza ithathe inkumbulo encane.

Ukuze wenze lokho kunezinketho eziningi, enye yazo is through iwebhusayithi ye-SmallPDF. Ngethuluzi lakho uku cindezela i-PDF awudingi ukufaka noma yiluphi uhlelo endaweni yangakini. Le ndlela ilula kakhulu, vele ulandele lezi zinyathelo:
- Finyelela iwebhusayithi ye-SmallPDF
- Chofoza inkinobho ethi "Khetha amafayela" noma uhudule bese uphonsa i-PDF ebhokisini lamathuluzi elibomvu kuwebhusayithi yakho. Kukhona nezinketho zokukwenza kusuka kusixhumanisi seGdrive noma iDropbox.
- Uma usukhethiwe, kufanele ulinde ukuze uqede ukulayisha efwini. Lokho kuzoyicindezela ngokuzenzakalela. Izokwazisa ukuthi usayizi wehlisiwe kangakanani.
- Manje udinga nje ukucindezela "Landa" ukuze inguqulo ye-PDF icindezelwe ilandelwe kukhompyutha yakho. Njengoba ukwazi ukubona, manje incane.
Kule webhusayithi ungenza futhi Ezinye izenzo ngemibhalo yakho ye-PDF, ukuthi ungaguqula kanjani amafomethi, uhlangane, uhlele, uvikele futhi usayine.
