Addition of horizontal scroll and vertical scroll

[murata2makoto]

I created two example EPUB publications for vertically scrollable manga and horizontally scrollable emakimono (horizontal, illustrated narrative form created during the 11th to 16th centuries in Japan).

Thanks @murata0204 ! Note that there is a typo in "horiozntally-scrollable-emakimono" (should be "horizontally")

Just out of curiosity, I loaded your EPUBs into the Readium "cloud / web reader", directly from your GitHub repository URL.

Unsurprisingly, horizontal scrolling does not work, as this feature is not implemented:

Vertical scrolling seems to work fine though (please check):

Interestingly, the EPUB3+ specification seems to explicitly forbid the use of scrolling rendition properties in fixed layout content. Am I right?

http://www.idpf.org/epub/31/spec/epub-packages.html#layout-property-flow

If a Reading Systems supports the rendition:layout property,
it must ignore the rendition:flow property when it has been set on a spine item
that also specifies the rendition:layout value pre-paginated.

Thanks, Daniel. I changed the directory name.
