EPUB kuya TIFF Imibuzo Evame Ukubuzwa Yokuguqulwa

Ngiyikhipha kanjani isihloko kusuka kuhele EPUB njenge TIFF?

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

Ingabe amakhasi encwadi ephinde iphinde

Ngokwenza ngazo kubungakanani bekhasi olukhethiwe kuqala, ngoba incwadi ephinde iphinde i

Ingabe i-TIFF ixhasa ukubukhali?

Ifomethi ikhona, kodwa umsuka awuna-alpha ukuwunika - amafreyimu wevidiyo namakhasi ashicilelwe agcwele ukucasuka, ngakho wonke ama-pixel afika aqinile. Isixhumanisi se-alpha sisebenza ngemuva: kusho ukuthi ungasakaza isiqephu se TIFF ngemuva ngaphandle kokushintsha ifomethi futhi. I-TIFF iphatha i-CMYK, 16-bit ububanzi, i-ICC ifaka amaprofayili namadokhumende amakhasi amaningi, okuwukuthi okuthile okudingekayo ukuphrinta nokugcinwa kwemisebenzi.

Ingabe amafayela TIFF azokhula kangako?

Okuningi kunalokho okubonayo, ngoba TIFF igcina wonke ama-pixel ngokugcwele kungafani nokulinganisela. I-1080p ihlala ifinyelela ku-2-5 MB futhi i-4K ihlala ifinyelela ku-6-15 MB, ngakho-ke ukukhishwa okude kusebenza ngokushesha. Lokhu kuyibhizinisi elilungile uma izithombe zidla ukukhiqizwa okuqhubekayo, futhi okubi uma zihamba ngqo kwikhasi le-web. I-TIFF iyindawo yokuqoqa engaphezu kwe-codec: ingagcina idatha engacindezelwanga, i-LZW, i-ZIP noma i-JPEG, kuze kube yi-32 bits ngasinye, ngekhasi eliningi kwifayela elilodwa.

DRM, cishe nganoma yisiphi isinqumo. I-EPUB ekhuselwe ibhalwe ngokufihlakele futhi ixhunywe ku-akhawunti, futhi akukho mguquli ongayifihla — sihlanganisa. Amafayela awenza wena, noma athengiswe esitolo esingena-DRM, uguqula ngaphandle kwezinkinga. I-EPUB ayinayo ikhasi eliqinile, ngakho-ke inani lekhasi alikho lutho, futhi ukwakheka okunzima — amathebulethi, izilinganiso, uhlu oluningi — kunzima kakhulu.

Ingabe ngithola isithombe esisodwa ngamakhasi?

Yebo - ikhasi ngalinye libonisa njengehele layo TIFF futhi iset ifika njenge ZIP. Ikhasi-lokulinganisa lokukhethwa kukho linciphisa lapho ufuna isigqoko noma isiqephu esisodwa, futhi limisa kukhasi elilodwa libuyisela ifayela elinye endaweni yokugcina.

Ngabe isinqumo sizophuma kanjani ku TIFF 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-TIFF izogcina i-EPUB iprofayili yombala wesigqoko?

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

Ingabe ngingakwazi ukukhishwa amakhasi athile we EPUB njenge TIFF, 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 TIFF amafayela. Esetshenziswa ukuqoqa iziboniso noma ukucindezela-ukuphawula kokuthengiswa.
