Indlela yokuguqula EPUB kuya BMP

Isinyathelo 1: Layisha eyakho EPUB amafayela usebenzisa inkinobho engenhla noma ngokuhudula bese uphonsa.

Isinyathelo 2: Chofoza inkinobho ethi 'Guqula' ukuze uqale ukuguqulwa.

Isinyathelo 3: Landa i-version yakho BMP amafayela

EPUB kuya BMP Imibuzo Evame Ukubuzwa Yokuguqulwa

Ngiyikhipha kanjani isihloko kusuka kuhele EPUB njenge BMP?

Layisha phezulu i EPUB futhi umguquli uthola isithombe sombhalo (ovame ukuphawulwa ku-OPF njenge `isithombe sombhalo`) futhi uyibuyisela njenge BMP. Ngokuzenzakalela sinikeza umbhalo ngesinqumo sayo esifakwe ngaphakathi; ukhetho oluthuthukisiwe "lokuguqula ubukhulu" lukuvumela ukuthi ubeke inhloso yobubanzi obuthile njenge-400x600 ye-thumbnail grid.

Ingabe ngizokwazi ukubonisa ikhasi ngalinye le EPUB njenge BMP?

Yes — switch the advanced option from "cover only" to "all pages" and we rasterize each EPUB page to a BMP at the chosen DPI, then bundle them in a zip. Reflowable EPUB pages render at a fixed page size (A5 / 6×9 / custom) before rasterization.

Ngabe isinqumo sizophuma kanjani ku BMP okhishwayo?

Iphutha liyi-1600×2400 (ibhokisi eliphakeme le-res elifanele ukuthunyelwa kwe-retailer). Izinketho ezithuthukisiwe zibonisa i-600×900 (isithombe esincane se-web), i-1200×1800 (ibhokisi le-Kindle store), i-1600×2400 (i-Apple Books / Kobo), kanye nezici ezijwayelekile ze-ad creatives.

Ingabe i-BMP izogcina i-EPUB iprofayili yombala wesigqoko?

Yebo — iprofayili ye-ICC efakwe ku EPUB ibhokisi (uma kune) igcinwa ku BMP. Iningi lencwadi ye-ebook elayishwe phezulu yi-ebook efakwe ku-sRGB, egcinwa yi-BMP. Ushicilelo olulungile lwe-CMYK, sebenzisa isikhashana /image-to-cmyk/ esisodwa ngemuva kokukhipha.

Ingabe ngingakwazi ukukhishwa amakhasi athile we EPUB njenge BMP, hhayi isibuko kuphela?

Yebo - ikhasi-lokulinganisa okuphezulu okukhethwa kuko lithatha izingeniso ezifana ne `1,3,5` noma `10-15` ukukhetha ukuthi iyiphi ikhasi elingeniswe EPUB eguqulwa ibe yi BMP amafayela. Esetshenziswa ukuqoqa iziboniso noma ukucindezela-ukuphawula kokuthengiswa.

Kungani i BMP iqoqo lami elikhishwayo limnyama noma liphansi?

I EPUB iqukethe isibuko esingu-low-resolution. Amabhukwana amaningi adala ahamba nge-600×900 noma ama-JPGs ancane we-cover - ukuphakama kwenza kube lula, hhayi okuqinile. Ukuthengiswa kwezimpahla, thola isibuko esingu-high-res kusuka kumshicileli ngaphezu kokuphakama kohlelo lwencwadi.

Yini mayelana nokubukeka okucacile ku BMP?

PNG BMP igcina ukubukeka okucacile uma i EPUB igqoka i-alpha channel (incane kuma-ebooks; ijwayelekile kuma-promo art). JPG BMP ayikwazi ukugcina ukubukeka okucacile futhi ifakazela kumhlophe. Uphawu / isithombe-skrini, bheka PNG noma WebP BMP.

Ingabe i-EPUB kuya ku-BMP iguqula umbhalo ube yizithombe zekhasi?

Akukho — u-rasterization ulungile nge-pixel. Umbhalo ku EPUB ikhasi ubonisa njenge-pixels ku BMP, akukho OCR noma ukukhishwa kombhalo kwenziwa. Uma umbhalo uhlela, sebenzisa /epub-to-docx/ noma /epub-to-txt/ endaweni yokuhamba kwesithombe.

Ingabe ihele lami EPUB liyimfihlo ngesikhathi sokukhipha BMP?

Yebo — amafayela alayishwe phezulu EPUB aqhubekelwa emisebenzini ehlukanisiwe futhi asuswa ngaphakathi kwemizuzu. Ukukhishwa kwebhokisi kufundeka nge-pass-one ngaphandle kokuhlolwa komuntu.

Ingabe kuthatha isikhathi esingakanani ukuveza ikhasi le-400 EPUB njenge-BMP amafayela?

Ukukhishwa kwebhokisi kuphela kushesha (ngaphansi kwamasekondi ayi-2). Uhlelo lokuphrinta lwencwadi ephelele ku BMP ku-150 DPI luthatha amasekondi angama-30-90 kuncwadi enekhasi eli-400; i-DPI ephezulu (300+) iphinda noma iphinda kabili lokhu.

Ingabe ngisebenzisa isigqoko esikhishwayo BMP ngokuhweba?

Yebo uma unelungelo lokugqugquzela (incwadi yakho, ukukhishwa kabusha kwendawo yomphakathi). Incwadi eshicilelwe ibhalwe ngesandla ivame ukube yiyo eshicilela; sizokhipha kuphela amapixels — asishintshi isimo selayisense se EPUB esingaphansi.

Yini ubukhulu befayela le BMP isihloko esikhishwayo?

I-1600×2400 iphoyinti e JPG quality 90 yi-300-800 KB; izici ezifanayo e PNG yi-1-3 MB. I-"quality" ethuthukisiwe ikhetha ubukhulu befayela ngokumelene nokucindezelwa kwe-artifacts ku BMP kuphuma.
