Shapes and exclusions

[Andreas Jung]

Hi there,

I am trying to get a simple example 

https://github.com/zopyx/css-paged-media-tutorial/blob/master/vivliostyle/exclusions/test.html

working with vivliostyle-formatter.

The expected result is 

https://raw.githubusercontent.com/zopyx/css-paged-media-tutorial/master/vivliostyle/exclusions/expected.png

Is there anything missing in order to receive the same result with Vivliostyle?

Hi,

Current implementation of Vivliostyle does not support 'shape-outside’ specified on arbitrary elements.
‘shape-outside’ has effects only when it is specified on boxes defined with EPUB Adaptive Layout rules (@-epubx-partition, @-epubx-page-master etc.).
We certainly want to support shapes and exclusions for arbitrary elements in the future, but the schedule has not been determined yet.

Could you help me out with a corrected version of the styles that would work with Vivliostyle?

The lack of documentation (The "EPUB adaptive layout" spec is not a documentation and samples are too huge to learn from) or simple self-contained examples are

currently the biggest problem of the problem when it comes to wider adoption. As I wrote earlier I am happy to help out with examples and documentation but

right now I have some serious problem getting the foot on the ground.

I forked your repository and pushed a modified version that works with Vivliostyle.
If you want a pull request, I am happy to create one.

Please note that the EPUB Adaptive Layout spec is not on the standard track and, though it works with the current Vivliostyle,
it is possible that we drop its support at some point in the future.
Also note that the EPUB Adaptive Layout spec refers an old version of Exclusions and Shapes Module and the syntax is different from the latest Shapes spec:

Sorry for your inconvenience.
We want to address the problem soon, but our resource is limited and we have a lot of work to be done.

As noted earlier, it is not certain how long we keep the support for EPUB Adaptive Layout spec.
Rather, we are going to work on adding support for W3C CSS specs like CSS Paged Media, CSS GCPM, Shapes and Exclusions etc.
It is also possible that we pick useful features in EPUB Adaptive Layout spec and propose them as new CSS features at W3C CSS Working Group.

Thanks KAWAKUBO, this is very helpful and brings me a step forward with my experiments.
