Uma ufunda kakhulu kuthebhulethi yephepha ledijithali futhi ujwayele ukushintsha phakathi kwamafomethi, kungokwemvelo ukuzibuza ukuthi ulenza kanjani ibhuku le-EPUB libukeke liphelele njenge-PDF ephawuleka kabusha. Nakuba i-reMarkable isekela kokubili i-EPUB ne-PDF, kunezimo lapho i-PDF inikeza ulwazi olungcono. ifomethi engaguquki, amamajini angaguquki, nolwazi olubikezelwayoikakhulukazi uma ufuna ukugcina ukwakheka okuzinzile, amafonti, noma ukwahlukanisa kwamakhasi.
Emigqeni elandelayo, sizobuyekeza isisombululo esizibambele ngokwakho esisuselwe ku-Caliber (ne-Docker) eguqula i-EPUB ibe yi-PDF elungiselelwe i-Remarkable Paper Pro, ifonti engukhiye nezilungiselelo zombhalo wekhodi, imikhawulo evamile yezinsizakalo ze-inthanethi (okuhlanganisa nezinhlelo ze-PRO), kanye nokuhambisana kwangempela nezincwadi ezine-copyright. Konke okudingayo ukuze wenze izincwadi zakho zibukeke zizinhle kulapha. amathiphu asebenzayo, izexwayiso zokuphepha, nezinketho zokwenza ngendlela oyifisayo.
Kusho ukuthini ukuguqula i-EPUB ibe yi-PDF ukuthi iphawuleke kabusha?
Ake siqale ngezinto eziyisisekelo: I-PDF iyifomethi yedokhumenti ye-elekthronikhi eyakhiwe i-Adobe eboleka izici ezivela olimini lwe-PostScript. Empeleni, i-PDF ingaxuba umbhalo, ihluzo zevekhtha, izithombe ze-bitmap, amafomu, kanye nemibhalo ye-JavaScript; empeleni, isibukeli esisemthethweni esisezingeni eliphezulu yi-Adobe Reader. Ukwazi lokhu kusiza ukuchaza ukuthi kungani, lapho uguqula i-EPUB ibe yi-PDF, uthola idokhumenti enesakhiwo esiqinile kanye nokulawula okuphezulu kokubukeka kwayo, into ethi ReMarkable ehumusha ku... amakhasi athembekile ngaphandle kokumangala kwe-ebb.
Manje, i-remarkable ifunda amafayela e-EPUB ne-PDF, kodwa ayiwavuli ama-ebook avikelwe nge-DRM. Uma uthenga ama-ebook ezitolo ezifana ne-Kindle, Kobo, noma i-Google Play, qaphela ukuthi ezinye izihloko zivikelekile, futhi ithebhulethi yakho izokwamukela kuphela okuqukethwe okungavikelwe. Kungenjalo, kukhona namakhathalogi amahhala lapho ungalanda khona izihloko ngaphandle kwemikhawulo. Kunoma ikuphi, umgomo wokuguqulela ku-PDF uwukuqinisekisa ukuthi, uma udluliselwa kudivayisi yakho, isethulo sihlala singaguquki. amafonti, isikhala somugqa, namamajini angaphansi kokulawula.
Ngokungafani namanye amathebulethi e-LCD anezinhlelo zokusebenza nezaziso, okuphawuleka kabusha kubeka kuqala isikrini sephepha ledijithali esingabenyezi kanye nomuzwa ongokwemvelo we-stylus. Lokhu kuhumushela ekufundeni okujabulisayo nasekubhaleni okusamanzi, kodwa futhi ne-ecosystem enomkhawulo. Uma kuqhathaniswa ne-e-reader yendabuko, i-reMarkable ikuvumela ukuthi ubhale futhi udwebe ngaphezu kokufunda, okwenza ukulungiswa kwedokhumenti kubaluleke kakhulu. Isichasiselo nokuzulazula kwekhasi akunazihibe.
Uma sikhuluma "ngokulungiselela okuphawuleka kabusha," iphrofayela yedivayisi, ukulungiswa, nokuphathwa kwefonti konke kuyangena. Kuvamile ukukhetha usayizi wefonti okhanyayo onokugqama okuhle, amamajini anengqondo, nosayizi bekhasi abaklanyelwe isikrini sakho. Ku-EPUB, ukugeleza kabusha kungashintsha kuye ngezilungiselelo; ku-PDF, ngakolunye uhlangothi, umisa leso sakhiwo, esikunikeza ukulawula okuphelele kulokho ozokubona ekhasini ngalinye.
Ngakho-ke, ukuguqula kusuka ku-EPUB kuya ku-PDF akukhona nje "ukushintsha amafomethi": kuhilela ukunquma ukuthi yiluphi uhlobo lokukhiphayo olufunayo, iyiphi ifonti okufanele ishumekwe, indlela yokusingatha izithombe, futhi, uma kunesidingo, ukukhetha iphrofayili ethile yomfundi ukuze ukugeleza kokuguqulwa kuhambisane nazo. imikhawulo ethile kanye nezinzuzo zocingo lwakho.
Isixazululo esizibambele ngokwakho nge-Calibre: iseva ye-remarkable
Enye yezindlela ezinamandla kakhulu zokulawula ukuguqulwa ukumisa isevisi yakho yewebhu esekelwe ku-Calibre. Kukhona iphrojekthi eshicilela isiqukathi se-Docker esinakho konke okudingayo kanye nesibonelo se-Docker Compose esinommeleli we-Nginx ukuze sihlanganiswe nengqalasizinda yakho. Lesi sixazululo, esiklanyelwe ukuthuthukisa okukhiphayo ku-ReMarkable Paper Pro, sikuvumela ukuthi uguqule i-EPUB ibe yi-PDF ngaphandle kokuthembela kubantu besithathu nangokulungisa... amapharamitha amahle usebenzisa okuguquguqukayo kwemvelo.
Inqolobane ihlanganisa isithombe esakhelwe ngaphambilini ukuze ungahlanganisi lutho, kanye ne-Dockerfile uma ukhetha ukuzakhela ngokwakho. Isebenzisa i-Caliber ukuze iguqule kanye nomndeni wefonti ochazwe kusengaphambili, i-IBM Plex, ekhethelwe ukufaneleka kwayo nobuhle bayo; Yebo, ungakwazi ukuguqula isethi yefonti ngendlela othanda ngayo. Ngenxa yamapharamitha angokwezifiso, ungashintsha amamajini, usayizi wekhasi, imethadatha, nokuziphatha kokunikezela ukuze uzuze imiphumela oyifunayo. i-PDF ehambisana nokuphawuleka kwakho kabusha.
Phakathi kwemininingwane ethokozisayo, inqubekelaphambili ebonakalayo ingabambeka ku-70% isikhathi eside. Lokhu akusho ukuthi isimile: I-Caliber imane iqedelela izigaba zokunikeza nokupakisha. Ukwengeza, uhlelo lubeka umkhawulo wesikhathi semizuzu emi-5 ngomsebenzi ngamunye ukuze kuvinjwe umthwalo osindayo wokushayisa insiza; lesi sikhathi sokuvala siyalungiseka ngokusebenzisa okuguquguqukayo kwemvelo. Ngemva kwalesi sikhathi, inqubo yokuhlanza ngokuzenzekelayo iyenzeka, isusa amafayela esikhashana (EPUB ne-PDF) ukuze kugcinwe isitsha. engenansalela futhi enesitoreji esilawulwayo.
Le sevisi iphinde inikeze i-REST API eyisisekelo, eyanele ukulayishwa kwe-EPUB ngokuzenzakalelayo, ukuqalisa ukuguqulwa, nokulanda umphumela ngemibhalo uma ukhetha ukungasebenzisi isixhumi esibonakalayo sewebhu. Kuyi-API "rudimentary" eklanyelwe ukumboza okubalulekile, kodwa ingena kahle ekugelezeni komsebenzi we-CI noma amathuluzi omuntu siqu. Ngokubukeka, isiphetho sangaphambili senza lokho okufanele sikwenze: ukhetha ifayela, ubone ukuqhubeka, futhi lapho usuqedile, isixhumanisi sokulanda sivela nesimo "ukuguqulwa kuqediwe." Konke ngaphandle kwe-fanfare, kodwa nge ngokwanele nje ukusebenza ngokushesha.
Isexwayiso esibalulekile esivela kumbhali wephrojekthi: ungavezi insizakalo ku-inthanethi ngaphandle kwezinyathelo zokuphepha, futhi ngokuvamile, ukusabalalisa okuvulekile akukhuthazwa. Kungcono ukuyigcina kunethiwekhi yangakini noma ngemuva kommeleli enobuqiniso nemikhawulo yokufinyelela. Khumbula ukuthi ukuguqulwa kudla izinsiza nokuthi amafayela owalayishayo angase azwele. Ngisho nokuhlanza okuzenzakalelayo, isu lakho elingcono kakhulu ukukusebenzisa ngokucophelela. Ukufinyelela okulawulwayo, i-HTTPS, umkhawulo wesilinganiso, namalogi abuyekeziwe.
Amapharamitha wokuguqula awusizo: amafonti, umbhalo wekhodi, nesifundi esiqondiwe
I-interface yokuguqulwa ngokuvamile ihlanganisa izinketho ezingokoqobo zokulungisa kahle imininingwane. Okunye okubaluleke kakhulu ukuthi "Shumeka ifonti": uma uthola izinhlamvu ezingajwayelekile (iziphimiso ezibekwe endaweni engafanele, izimpawu ezishintshile) lapho uvula i-PDF ngokuphawuleka kabusha, ukushumeka ifonti ohlwini olukhethiwe kuvame ukuyixazulula inkinga. Lokhu kuqinisekisa ukuthi i-typography ihamba nedokhumenti nokuthi ithebhulethi ayincikile ekushintsheni okwenziwa ngesandla; lokhu kunciphisa isidingo sokulungisa mathupha. ukunikeza amaphutha nezinkinga zokuhambisana.
Enye i-lever yokulungisa kahle "umbhalo wekhodi wokokufaka." Emabhukwini amadala noma amafayela akhiqizwe ngamathuluzi angajwayelekile, ukubhala ngekhodi okuzenzakalelayo kwe-EPUB kungase kungafani nokulindelwe. Ukuphoqelela umbhalo wekhodi othize kuvumela izinhlamvu ezikhethekile ukuthi zihunyushwe ngendlela efanele ngaphambi kokuguqulelwa ku-PDF. Kuyimininingwane encane kodwa ebalulekile yokuqinisekisa ukuthi umphumela wawonakele. izisho eziphukile, izikhala ezimbili, noma izimpawu eziyinqaba.
Inketho ethi "target ebook reader" nayo yenza umehluko. Ukukhetha idivayisi eqondiwe kusiza i-Caliber ukuthi isebenzise iphrofayela enobukhulu bekhasi, amamajini, nokukala okudizayinelwe leso sikrini. Uma umfundi wakho evela, yikhethe; uma kungenjalo, khetha okufanayo okuseduze. Isevisi ezibambele yona eshiwo ihlanganisa iphrofayili ye-reMarkable Paper Pro kanye neyodwa ye-Boox Air 4C, iwusizo uma wabelana ngokugeleza komsebenzi nabangani abasebenzisa leyo modeli. Lawa maphrofayili akusiza ukuthi uzuze i-PDF ebukeka iyinhle. ngaphandle kwesidingo sokuthinta kabusha okwengeziwe.
Okokugcina, ungawabukeli phansi amandla emethadatha. Ukushintsha "isihloko" kanye "nombhali" ngokuqondile phakathi kokuguqulwa komsebenzi kugcina ilabhulali yakho ihlelekile futhi kulula ukuyicinga, kukho kokubili kukhompuyutha yakho futhi iMarkable kabusha. Uma uvame ukuchasisa noma uhlukanise ngokubhala, ukuchaza lezi zindawo ngokucacile konga isikhathi kamuva. Amabhokisi ombhalo ambalwa nje futhi usuqedile. amagama ahambisanayo, amaqoqo ahleliwe nokusesha okusheshayo.
Izinsizakalo eziku-inthanethi nezinhlelo ze-PRO: lokho abakunikezayo
Uma ukhetha ukungahlanganisi lutho, zikhona abaguquleli be-inthanethi Bangakwazi ukuguqula i-EPUB ibe yi-PDF ngekhwalithi enhle. Kodwa-ke, izici eziningi ezikhawula kunguqulo yazo yamahhala futhi zigcine izici ezinhle kakhulu zama-akhawunti akhokhelwayo. Kuvamile kubo ukuthi bafune ukubhaliswa ukuze bavule okwengeziwe, futhi inguqulo ye-PRO ivamise ukunika amandla izinto ezifana nokuguqulwa okungenamkhawulo, osayizi bamafayela amakhulu, nezinketho ezithuthukisiwe. Noma kunjalo, inguqulo yamahhala imvamisa ikuvumela ukuthi uqhubeke nokusebenzisa isevisi ngokulinganiselwa okuthile. isivinini, inani, noma imikhawulo kasayizi.
Yiziphi izinzuzo ezijwayelekile ezinikezwa uhlelo lwe-PRO? Okokuqala, ukuguqulwa okusheshayo ngenxa yokubeka umugqa okubalulekile. Okwesibili, ukuguqulwa okungenamkhawulo, okuyisici esamukelekayo uma unomtapo wezincwadi omkhulu ongathutha. Okwesithathu, usayizi wefayela ongenamkhawulo wamaphrojekthi amakhulu anezithombe ezinzima. Okwesine, izici ezithuthukile azitholakali njalo ezinhlelweni zamahhala. Akuvamile ukuthi uchofoze inkinobho ethi "funda kabanzi" ukuze ubonise ukuphrinta okuhle ngayo yonke imininingwane yezici nezimo, ngakho-ke kuwumqondo omuhle ukuqhathanisa ngokucophelela. ngaphambi kokukhokha kusengaphambili.
Uma ukhetha lezi zinkundla, khumbula ukuthi ulayisha amafayela akho kuseva ongayilawuli. Cabangela ubumfihlo bamafayela akho, ikakhulukazi uma kungamadokhumenti omuntu siqu noma omsebenzi. Bangase bakukhiphe ekubopheni ukwenza imisebenzi yezikhathi ezithile, kodwa uma ukuguqulwa nokulawula kuwumkhuba wakho wansuku zonke, inketho yokubamba wena ne-Caliber iyisinqumo esingcono, njengoba ikunikeza. ukuzimela, ukulungisa okwenziwe ngendlela oyifisayo, nokuphepha kwepherimitha.
I-Kindle futhi Iphawuleka kabusha: I-DRM, amafomethi, kanye nendlela yokuphatha izincwadi zakho
I-reMarkable isekela i-EPUB ne-PDF, kodwa izincwadi eziningi ezithengwe e-Amazon ziyangena KFX, AZW, MOBI noma AZW3 amafomethi Futhi, ngaphezu kwalokho, avikelwe nge-DRM. Ngaleso sizathu, ukungenisa ngokuqondile lawo mafayela kuthebhulethi yakho ngokuvamile akusebenzi. Isixazululo esijwayelekile ukuwaguqulela ku-EPUB noma i-PDF, kusukela efayeleni elivuliwe. Kunamathuluzi okuthengisa, afana ne-Epubor Ultimate, edizayinelwe ukucubungula ilabhulali yakho ye-Kindle ye-PC/Mac futhi ithole amafomethi amukelwa idivayisi, enze ukuhamba komsebenzi kube lula. kuhlanganiswe kuzo zonke izinkundla zokufunda.
Ekusetheni okujwayelekile, inqubo izoba: faka ithuluzi kukhompuyutha yakho, landa amabhuku ku-Kindle ye-PC noma i-Mac ukuze atholakale ungaxhunyiwe ku-inthanethi, futhi usebenzise isofthiwe ukwenza i-EPUB ehlanzekile noma i-PDF ongayidlulisela ku-Remarkable. Uma eseguquliwe, amafayela amahhala agcinwa endaweni, futhi ungakwazi ukuvula ifolda lapho atholakala khona ukuze uwahambise kudivayisi yakho. Kubalulekile ukuhlola ukuthi ukuguqulwa ngakunye kukhombisa isimo esiyimpumelelo ngaphambi kokuqhubeka. kopisha umphumela kuthebhulethi.
Uma usulungise amafayela akho e-EPUB noma e-PDF, the dlulisela ku-Remarkable Lokhu kungenziwa ngokuxhuma ikhebula le-USB kukhompuyutha yakho noma ngokusebenzisa uhlelo olusemthethweni lwedeskithophu. Noma ngabe iyiphi indlela oyikhethayo, ukhiye uwukuqinisekisa ukuthi amagama wefayela nemethadatha kubukeka kulungile ukugwema izimpinda noma ukudideka. Uma amafayela esevumelanisiwe noma ekopishiwe, ilabhulali yakho izobonisa izihloko ngobuciko bawo bekhava nombhali, olungele ukulandwa. funda, dwebela futhi uchasise ngepensela.
Inothi elibalulekile elingokomthetho: i-landscape ye I-DRM nokususwa kwayo Iyahlukahluka ngezwe kanye nemibandela yokusetshenziswa. Qiniseka ukuthi uthobela imithetho esebenzayo namalayisense okuqukethwe okuthengayo. Ulwazi olunikezwe lapha lungokobuchwepheshe futhi luyafundisa; umthwalo wokusetshenziswa kwayo ungowomuntu ngamunye. Uma ufuna ukugwema izinkinga, beka phambili imithombo ye-ebook engena-DRM noma abashicileli abakuvumela ukuthi ulande amafomethi avulekile ahambisanayo.
Izinkinga ezivamile nendlela yokuzixazulula
Ingabe ibha yenqubekelaphambili ibambelele ku-70% isikhathi eside? Ungakhathazeki. I-Caliber igxilisa imisebenzi embalwa edinga izinsiza ekugcineni, futhi inkomba ingase ibonakale ifriziwe. Kunikeze isikhathi, ikakhulukazi uma i-EPUB iqukethe izithombe eziningi noma izitayela eziyinkimbinkimbi. Uma inqubo idlula umkhawulo wesikhathi esimisiwe (ngokuzenzakalelayo, imizuzu emi-5 kusevisi ezibambele yona), cabanga ukwandisa isikhathi sokuvala ngokushintshashintsha kwendawo noma ukwenza lula okokufaka. sheshisa ukuguqulwa.
Ingabe uyazibona izinhlamvu ezingavamile ku-PDF ewumphumela? Nika amandla inketho yokushumeka ifonti bese uzama ifonti ehlukile. Ngokuvamile, ithebhulethi izama ukufaka ifonti esikhundleni bese yehluleka ngama-glyphs athile. Ngokushumeka, uqinisekisa ukuthi idokhumenti inefonti yayo engaguquki futhi ihunyushwa ngendlela efanayo yonke indawo. Uma isahluleka, shintsha okokufaka ikhodi ukuze injini ikwazi ukukucubungula ngendlela efanele. ama-accents, ama-ñ kanye nezimpawu ezikhethekile.
Ingabe i-PDF ibonakala iyincane kakhulu noma inkulu kakhulu ekuphawulekeni kabusha? Hlola iphrofayela "yesifundi se-ebook esiqondisiwe" futhi ulungise amamajini. Iphrofayela efanelekile ifana nosayizi wekhasi nokuminyana kombhalo esikrinini sethebhulethi yakho, ivimbela ukusondeza okungadingekile nokufunda okungakhululekile. Uma iphrofayela ethile ingekho, khetha eyodwa kudivayisi enobukhulu obufanayo, noma uchaze ngokwakho usayizi namamajini ukuze ufinyelele isici esilungile. ukufunda okunethezekile nendawo esetshenziswa kahle.
Ingabe uhlangabezana nemikhawulo ngamasevisi aku-inthanethi? Mhlawumbe usayizi wefayela lakho le-EPUB weqa umkhawulo ovunyelwe, noma uhlelo lwamahhala lubeka isikhathi eside sokulinda. Cabangela ukuthi uhlelo lwe-PRO lufanelekile yini uma ubheka umsebenzi wakho, noma uma ungathanda ukuthuthela endaweni ozisingathile lapho ubeka khona imikhawulo. Emitapo yolwazi emikhulu noma amaphrojekthi avelayo, ukulawula ipayipi ngokuvamile kunciphisa ubuhlungu bekhanda futhi konga isikhathi. ukungaqiniseki kwezikhathi nolayini.
Ingabe isevisi yakho ozibambele yona iphelelwa yindawo? Nakuba kunokuhlanza okuzenzakalelayo ngemva kokuphela kwesikhathi, ukungena emkhubeni wokuqapha uhla lwemibhalo lwesikhashana kusiza ukuvimbela ukuchichima. Ukuhlela ukuhlanzwa ngezikhathi ezithile kanye nokubheka amalogi esiqukathi kugcina isistimu inempilo. Uma futhi ukhawulela usayizi wefayela lokufaka (isibonelo, ngokulungiselela izithombe ngaphakathi kwe-EPUB), uzothuthukisa ukusebenza futhi wehlise... ukwehluleka kwenkumbulo noma ukugcinwa.
Ukuphepha nokusebenza okuhle kakhulu
Uma uzophakela isiguquli ekhaya noma emsebenzini, kwenze lokho ngemuva kommeleli okhona we-Nginx one-TLS kanye nokuqinisekisa. Gwema ukukuveza obala ku-inthanethi, ikakhulukazi uma umbhali eluleka ngokumelene nakho. Ukuguqulwa kwedokhumenti kuyisevisi esilingayo yokuhlukumeza okungahlosiwe uma ifinyeleleka esidlangalaleni, ngakho lungiselela ukufinyelela okunomkhawulo, sebenzisa imikhawulo yesilinganiso, futhi uqinisekise ukuthi amalogi akho ayazungeziswa ukuze uvimbele ukuvuza kwemethadatha. Lokhu kuzosiza ukugcina ukuphepha kwesistimu. iphephile, ihlanzekile futhi ingaphansi kokulawulwa.
Chaza okuguquguqukayo kwendawo okunengqondo ngesikhathi sokuvala kanye nemibhalo yesikhashana. Emishinini enesizotha, umkhawulo wemizuzu emi-5 uvikela ukuzinza; uma unezinsiza ezengeziwe noma umsebenzi osindayo, wandise ngobuhlakani. Ukuhlanza okuzenzakalelayo kuyinetha yakho yokuphepha, kodwa unganciki kukho ngokungaboni: qinisekisa ngezikhathi ezithile ukuthi ama-EPUB nama-PDF esikhashana ayahlanzwa ngempela ukuze uwagcine. isikhala samahhala nesivinini sokuphendula.
Ukukhetha ifonti efanele kuyisihluthulelo. I-IBM Plex, eza njengokuzenzakalelayo kusevisi eshiwo, inikeza ukufundeka okuhle, kodwa ungakhetha enye ifonti oyithandayo ebukeka iyinhle ku-e-ink. Gwema amafonti azacile kakhulu noma lawo anokugqama okuphezulu uma ufunda ezindaweni ezahlukahlukene. Ukuhlala ushumeka ifonti oyikhethile ku-PDF kuqinisekisa ukuthi Okuphawuleka Kabusha kwakho kuyiveza ngendlela othanda ngayo, kuqinisa... ikhwalithi ebonakalayo yezincwadi zakho namanothi.
Uma uhlela ukwenza ngokuzenzakalelayo nge-REST API eyisisekelo, bhala phansi ukugeleza komsebenzi wakho: Ukulayisha kwe-EPUB, isiqalo sokuguqulwa, ukuhlola isimo, nokulanda. Ngisho negobolondo elilula noma i-Python wrapper izokusindisa ukuchofoza futhi ikuvumele ukuthi uhlanganise isiguquli sakho kuzinqamuleli noma imibhalo yangokwezifiso. Futhi khumbula, i-API "iyisidala": ilungele imisebenzi elula, ephindaphindekayo engadingi ukuthunyelwa okugcwele. akukho ukuncika okuyinkimbinkimbi noma okweqisayo.
Ekugcineni, ufinyelela ibhalansi phakathi kokunethezeka nokulawula: isevisi eku-inthanethi ingase yanele ukusetshenziswa ngezikhathi ezithile; isiqukathi esine-Caliber sikunikeza ukuzimela, amaphrofayili athuthukisiwe, namamethrikhi angabikezelwa. Kuzo zombili izimo, into ebalulekile ukuthi ama-EPUB akho aguqulelwa ngokuthembekile abe yi-PDF, namafonti aqondanisiwe, umbhalo ohunyushwe kahle, kanye nemethadatha ehlanzekile, ukuze i-reMarkable yakho yamukele. amadokhumenti aphucuziwe, alungele ukufundwa nokuchazelwa.
