Question

PDF VS CBR/CBZ 2020 ?

Hi Adobe Community,

 

   People prefer using CBR/CBZ format for reading eBook/Comics, why ? I love reading my Comics in PDF Format with Adobe Reader. I know that the people use "CDisplayEx" for reading Comics in CBR/CBZ.

 

What is the future for the PDF Format ? Could Adobe create a new format "PDZ" or "PDCB" for instance for reading Comics like with CDisplayEx ?

 

Greetings

    If we convert image files of .cbr (.zip) and combine them as to create .pdf file, image quality drastically gets decreased, also the smoothness of jpeg files gets compromised.
    while CDisplayEx does not support continuous scrolling as adobe reader do, but adobe reader (while not showing page gap), shows a dashed line hamper the experience of webtoon comics.
    None of them is perfect, even though both have a very small issue that makes a big and bad impact on user experience.
    Hey Adobe can you provide an option for not showing the dashed line on hiding page gap

    These files are nothing more than zip (or rar) files with image files in them, with a dedicated software that displays them in a certain way. A PDF file is much more portable and can contain much more information than that, for example, real text that you can search, copy, etc.

    Hi,

     

       I am agree with try67 but : Could "Adobe Acrobat" use a (new) format in "PDF" similar like .ZIP/.RAR for opening/reading the PDF faster only for the Comics Books ? We know that PDF file can contain much more information but I think the a new format might be creating against CBR/CBZ format !

     

    PDZ => PDF compressed in ZIP (contains images/pictures) + information compatibility Adobe ?

    PDR => PDF compressed in RAR (contains images/pictures) + information compatibility Adobe ?

     

    Else PDCB => PDF compressed like ZIP/RAR (contains images/pictures) + information compatibility Adobe.

    I don't see the point. Adding another layer of compression will not make loading files faster, but slower.

    And a file that contains compressed images with additional information it just a regular PDF...
