Guqula EPUB ukuba PDF

Hayi - olu guqulelo luyipinsa i layout. A EPUB ilungelelanisa umgca wayo wokuyeka nakweyiphi na ububanzi nobungakanani bohlobo lwegama umfundi osebenzisayo; i PDF ilungisa iphepha lobeko lwesikwere kwixesha loguqulelo, ngoko kwifowuni ufumana iphepha lonke elilinganiselwe phantsi kunokuba umbhalo uphinde ujikelezwe kwisikrini. Lo ngurhwebo olulungileyo xa i layout kufuneka ingatshintshi, kwaye enye engalunganga xa ifayile ifunde kwicebo elincinci. I-EPUB iphinde ijikeleze umbhalo nakweyiphi na ubungakanani bekhusi nakweyiphi na ubungakanani bohlobo lwamagama, eyenza ukuba ifundeke kwifowuni kunye nomfundi we-e. I-PDF yifomati yoxwebhu olunokuthunyelwa lwe-Adobe ukusukela ngo-1993, emiselwe njenge-ISO 32000 kwaye ngoku yifomati yoxwebhu olunombala oqinileyo.

Ewe apho zombini iifomati zingazichaza. Ubugcisa besiqhoboshelo, iziqalelo zokwahlula kunye netheyibhile e navigable yezinto eziquletheyo zii metadata ezidityanisiweyo, ngoko zihamba ngaphezulu kunokuba ziphathwe kumbhalo. Iinkcukacha ze footnote kunye neengxelo zesalathisi ziinxalenye ezibuthathaka - zihlambuluka kumbhalo ongaphakathi komgca kwinjongo ngaphandle kwendlela ye ankile.

Ewe, kwaye EPUB ayizukuba nayo. Iibrawuzi zithumela ikhowudi yokufikelela kwi PDF kwaye akukho nto kwi EPUB, ngoko EPUB ikhonkco libangela ulayisho ezantsi ngelixa i PDF ibonisa umgca. Oku kuqhelekileyo kubangela ukhetho xa ifayile isiya kwiphepha le web kunokuba ifike kwisicelo. I-PDF ibonakala ifana nge-byte nge-byte kwi-machine nganye ne-printer nganye, oko kukuthi, ikontraki, i-fax kunye nephepha elifundiweyo zonke zihlala kulo.

DRM, kwimeko eninzi. I-EPUB ekhuselekileyo ikhowudiwe kwaye idityaniswe kwi-akhawunti, kwaye akukho mguquli unokuyikhuphela ikhowudi — i-DRM yethu iquka. Iifayili ozivelise ngokwakho, okanye ozithengise kwi-DRM-free store, ziguqulwe ngaphandle kwengxaki. I-EPUB ayinalo ushicilelo oluthe nkqo, ngoko ke amanani ephepha ayingomsebenzi, kwaye ubeko olunzima - itephu, i-equations, i-multi-column - luyikhupha kakubi.

Ixhomekeke ngokupheleleyo ukuba umbhalo obonakalayo ukhona. I PDF eyenziwe kuxwebhu ithatha umphezulu wombhalo obonakalayo kwaye ifuna ukukhangela; i PDF eyenziwe kwiskrini okanye imifanekiso ngumfanekiso wombhalo kwaye ayiyiyo, de i OCR ifake umphezulu. / pdf- ocr / iyenza loo nto, kwaye ifanele iqhube phambi kokuba nayiphi na uguqulelo olulindele ukufunda amagama.

Ewe - iinketho eziphambili zibonisa ubungakanani bephepha (A4, A5, incwadi, 6×9 urhwebo lwephepha elijikelezayo, isiko), umda omiselweyo (ofutshane / oqhelekileyo / obanzi), kunye nobungakanani bomgca. A5 + 11pt kukungagqibekanga okuqhelekileyo kwe-e-reader-like; 6×9 + 11pt ihambelana nezinye iiphepha ezishicilelweyo ezijikelezayo.

Ewe - ifonti kwi EPUB OPF ifundwa kwaye ifakwe njenge PDF ifonti yeqela eliphantsi kwi PDF, ngoko ke isiphumo sibonisa ngokufanayo kwimboniselo ye PDF. Ukuba i EPUB isebenzisa ifonti ngaphandle kokufaka imvume, sifaka ilayisensi- ecacileyo yokubuyela umva (DejaVu Serif / Sans).

Ewe - i NCX / nav ukusuka kwi EPUB iguqulwe kwi PDF amanqaku encwadi (iqela lenjongo ethile ye Acrobat / Imboniselo) NOluhlu lweekhonkco ezinqakraza kwi PDF iphepha le TOC elinikezelwe. Zonke zidibanisa kwi PDF elungileyo yephepha le ankile.

Imifanekiso kwi EPUB ifakwe kwisigqibo sayo esisemthethweni. Ububanzi bumiselwe kwi PDF isakhelo sombhalo; imifanekiso engaphezulu kwekholam ilinganiselwe phantsi ukuze ilungele. "Umgangatho womfanekiso" ukhetho oluphambili lulawula umgangatho wokubuyisela ukukhowuda (95 = uvimba, 75 = uqinile).

Ushicilelo lweshishini, tshintshela iinketho eziphambili kwi 300 DPI / CMYK / akukho- buhlungu. Okungagqibekanga PDF imveliso iscreen- elungelelanisiweyo (RGB, 150 DPI), elungileyo yoshicilelo oluzenzekelayo kwi laser yasekhaya kodwa ekhanyayo kwi offset / ushicilelo oluzenzekelayo oluzenzekelayo.

Isiqendu-sokuqala "soloko-kwiphepha-ekunene" CSS kwi EPUB ifaka amaphepha amnyama e-verso, njengeencwadi ezishicilelweyo. Khubaza "ukwenza isiqendu siqale kwiphepha elincinane" ukhetho oluphambili lokususa; urhweba ubeko olufana nencwadi ngephepha-elincinane elincinci PDF.
