EPUB ukuba GIF Imibuzo Ebuzwa Rhoqo Ngokuguqula

Ndiyikhupha njani i-cover kwi-EPUB ifayile njenge-GIF?

Layisha phezulu i EPUB kwaye umguquli ufumanisa umfanekiso wesiqulathi seefayili (oqhelekileyo uphawulwe kwi-OPF njenge `imifanekiso yesiqulathi seefayili`) kwaye uyibuyisele njenge GIF. Ngokungagqibekanga sinikezela isiqulathi seefayili kwisisombululo sayo esifakwe ngaphakathi; ukhetho oluphambili "ukuguqula ubungakanani" lukuvumela ukuba ubeke emngciphekweni ububanzi obuthile njenge-400×600 ye-thumbnail grid.

Ingaba i GIF iya kuvula ngokuthe ngqo kwi-browser?

Ewe, kwaye EPUB ayizukuba nayo. Iibrawuzi zithumela ikhowudi yokufikelela kwi GIF kwaye akukho nto kwi EPUB, ngoko EPUB ikhonkco libangela ulayisho ezantsi ngelixa i GIF ibonisa umgca. Oku kuqhelekileyo kubangela ukhetho xa ifayile isiya kwiphepha le web kunokuba ifike kwisicelo. Umfanekiso ojikelezayo we GIF udlala ngokucacileyo naphi na - abaxhasi be-imeyili, iiforums, iinkqubo zokuncokola kunye neebrowser zonke ziyibonisa ngaphandle konxibelelwano lwe-codec.

Iphepha lencwadi ephindayo liguqulwa njani libe yimifanekiso ethe nkqo?

Ngokwenza ngazo kubungakanani bephepha olukhethiweyo kuqala, kuba incwadi ephindayo ayinamaphepha angaphakathi - umfundi uyenza ukusuka kwiscreen ububanzi kunye nobungakanani bomgca. Umguquli ukhetha iphepha eliqhelekileyo lobunzulu bomhlaba, ubeka umbhalo ngaphandle kuyo, kwaye uyenza iphepha ngalinye eliphumayo njengomfanekiso omnye. Tshintsha ubungakanani bephepha kwaye ufumana inani elihlukileyo lemifanekiso kwincwadi efanayo.

Ingaba i-GIF ixhasa ukubonakaliswa ngokucacileyo?

Ifomati isebenza, kodwa umbhali akafuni i-alpha ukunika - ii-frames zevidiyo kunye neephepha ezibonisiweyo zicacile ngokupheleleyo, ngoko ke zonke ii-pixels zifika ziqinile. Isiqhagamshelanisi se-alpha sihlala sisetyenziswa emva koko: kuthetha ukuba ungacima into ephuma kwi-GIF kamva ngaphandle kokuguqula i-format kwakhona.

Ingaba iifayili GIF ziya kuba zikhulu kangakanani?

Ikhulu kunalo lonke ulindeleyo, kuba GIF igcina i-pixel nganye ngokuchanekileyo kunokuba ilinganise. I-1080p ihlala iwela ngaphantsi kwe-2-5 MB kwaye i-4K ihlala ngaphantsi kwe-6-15 MB, ngoko ke ukuphuma okude kudibanisa ngokukhawuleza. Oku kurhwebo oluchanekileyo xa imifanekiso i feed iqhubekeka, kwaye okubi xa zihamba ngqo kwiphepha le-web. I-GIF ayilahleki kodwa iphele kwi-256-imibala yengqokelela yezixhobo ngesakhelo ngasinye, isebenzisa uxinzelelo lwe-LZW kunye nokukhanya okubini kombala omnye.

Kutheni i-EPUB ifayili yam i refuses to convert?

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.

Ndingaguqula kuphela inxalenye ye EPUB endaweni yobuninzi bayo?

Ewe - uluhlu lwephepha lokhetho luthatha `1- 5`, `1,3,5` okanye `zonke`, ngoko isithuba esifanayo, isiqalelo okanye isiqulathi seefayili singasuswa ngaphandle kokusebenzisa isiphelo. Kuxwebhu olude olu lutshintsho phakathi kweefayile ezincinci kunye neekhulu ezininzi.

Ndingazibonisa njani zonke iphepha le EPUB njenge GIF?

Ewe - tshintsha ukhetho oluphambili ukusuka "kuquka kuphela" ukuya "kuzo zonke iphepha" kwaye sizaku raster iphepha ngalinye EPUB kwi GIF kwi DPI ekhethiweyo, emva koko siyibeke kwi zip. Amaphepha aphinda ajikeleze EPUB abonisa ubungakanani bephepha oluthe nkqo (A5 / 6×9 / impahla) phambi ko rasterization.

Kwisigqibo esingakanani esiphumayo siphuma i-GIF ekhutshiweyo?

Okumiselweyo ku 1600×2400 (umgangatho ophezulu wokufaka umgca ofanelekileyo wokukhuphela umrhwebi). Iinketho eziphambili zibonisa 600×900 (imifanekiso eqingqiweyo yewebhu), 1200×1800 (umgangatho weKindle shop), 1600×2400 (iApple Books / Kobo), kunye nobungakanani obuzithandayo bokwenza i-ad.

Ingaba i-GIF iya kugcina i-EPUB iprofayili yombala wesiqulathi seefayili?

Ewe — I-ICC profile efakwe kwisigqubuthelo EPUB (ukuba kukho) igcinwa kwi GIF. Iincwadi ezininzi ze-ebook ezilayishwe phezulu zihamba njenge-sRGB, egcina i GIF. Ushicilelo olukhawulezayo lwe-CMYK, sebenzisa i-/image-to-cmyk/ ehlukileyo emva kokukhupha.

Ndingazikhuphela njani iphepha elikhankanyiweyo le EPUB njenge GIF, hayi kuphela isiqulathi seefayili?

Ewe - ukhetho oluphambili loluhlu lwephepha luyavuma izingeniso ezinjenge `1,3,5` okanye `10-15` ukukhetha iphepha elibonisa EPUB eliguqulwa libe GIF iifayile. Isetyenziswa ukutsala imifanekiso okanye ukutsala-ukucofa ukuthengisa.

Ukuthengiswa kweempahla, mthombo we-high-res umgca ogqibeleleyo ovela kumshicileli kunokuba ukhuphelo lwencwadi.
