Style file for iPad?

Style file for iPad?

If this has been asked before, my apologies.

Is there a style file for formatting PDFs from ConTeXt for reading on an
iPad?  So far I've just used

\setuppapersize[A4][A4]
\setuplayout[backspace=20mm,
width=160mm,
topspace=20mm, top=0mm,
header=0mm, footer=10mm,
        bottomspace=20mm,bottom=0mm,
textheight=250mm]

which works fine - for printing - but isn't optimized for the iPad.  If
anybody has any suggestions or examples, I'd be very grateful of them!

Thanks,
Alasdair

 make an ebook instead. PDF files aren’t for screen reading, but for
printing.

semantic markup like it is used in ebook formats is much better suited for
screens of all sizes.

Yes, but what ebook formats handle mathematics and diagrams?

copied from s-inf-03.mkiv

\setuppapersize
   [S6,landscape]
   [S6,landscape]

\setuplayout
   [header=0cm,
    footer=1cm,
    backspace=.5cm,
    topspace=.5cm,
    width=middle,
    height=middle]

(not that I use the ipad for reading docs ... too must hassle to get 
something on it)

Plus the poor layout support in almost all ebook readers (brain dead
paragraph builder, no hyphenation, no OpenType support etc. etc. they
are usually pieces of junk for any remotely complex text layout job).

I use the following style for an ebook reader:

https://gist.github.com/1886670

I set the paper size to the physical size of the device 
screen, use tiny margins, and set an appropriate font size.

See 
http://randomdeterminism.wordpress.com/2009/10/21/creating-a-style-file-in-context/ 
for example output.

A5 is closer to the screen size than S6.

S6 has an 3:4 aspect ratio

It's worse than pre-TeX printed books. Which makes me wonder: is anyone in the 
world addressing this? Are there people in the TeX community involved in the 
standardization processes (say, Epub3, but also the various W3C specifications), 
who could push forward ideas from TeX, like minimum requirements for the 
algorithms that rendering engines should use? These questions (together with 
sighs) arise every time I see a web page especially with mathematical notation…

The problem is, since the rendering is based on HTML, people just grab a web browser framework and build on that to make an ebook viewer.

Here's a post I wrote up once comparing a specific ePub display on a specific viewing program w/ a hand-tweaked Plain TeX version:

A while ago I grabbed some mathematics book samples for the Kindle.  These
were books produced by well-known publishing companies, retailing for
considerable sums (even in the electronic versions), and in all of them the
mathematics typesetting was atrocious.  I think that in most (all?) ebook
formats, a formula is included as an image, which means that it
automatically resizes.  This means that formulas may be of all different
sized fonts, which gives the result a very scrappy look.  At least PDF -
even if not designed for ebook reading - provides decent layout.

The problem is not just mathematics.  I have some ebooks about poetry, and
in them the included poems (as set off from the surrounding text), seem to
be typeset almost randomly, with regard to layout, font size and spacing.
 And these are commercial ebooks, for which I paid real Earth dollars!
