I will channel our dearly departed Les Koehler and suggest that, given
the average age of the Rexx-programming cohort, a larger font may be
better. :-)

Newest version of rxmath HTML files/folders is here

believe I've gotten the majority of the issues handled so please
have another look.
Thanks, Gil

Hi P.O.,
Thanks for doing the detailed comparison and confirming that the
differences were ones of which I was aware.
I have experimented with deleting the width=297 from BOTH the div
tags and the span tags and the results look great! Now to find how
that attribute is getting generated!

Dear Gil,
Rony have given most of the information already but I have listed
some differences as seen in the output, please have a look in the
attached pdf
For what is is worth: most differences I can see are to your
advantage! I think this is coming a long way already.

Thanks a lot Rony for that research! I had noticed that the HTML
produced by Publican used object tags while the newer Docbook
stylesheets produced img tags but that is as far as I had
gotten. Now to see where the width=297 comes from and what
happens when it is removed. Thanks again! GB

I've made more progress here and now have a set of HTML files,
etc. for the rxmath book. In spite of the fact that the source
is essentially the same and the stylesheets are as well, the
output appears different in a number of ways. I can only
attribute this to the different versions of the DocBook
stylesheets being used by the two processes or possibly the
different way the two handle xinclude. I have put the zipped

Your HTML renderings look great, even better than P.O. Publican
renderings, congratulations !!
The area that needs attention is how the size for the graphics
gets defined, it is also where your renderings look better than
Publican's, where clipping occurs. Example:
* 2.3 RxCalcSqrt()
o Gil's HTML text for the syntax diagram:
<div class="mediaobject"><img src="images/funcs/funcs_rxcalcsqrt.svg"
width="297" />
o Publican's HTML text for the syntax diagram:
<div class="mediaobject"><object data="images/funcs/funcs_rxcalcsqrt.svg" type="image/svg+xml"
width="297"> </object></div>
The general problem with the definition of the size of the
syntax diagrams lies in setting the width to the absolute value
"297" pixels!
The original docbook text for this is:
<imagedata fileref="images/funcs/funcs_rxcalcsqrt.svg" scale="55" />
The svg has a bounding box of 472x68:
<svg xmlns="http://www.w3.org/2000/svg"; width="472" height="68">
So it seems that "297" is probably hardcoded in the xsl.
This has in principal the downside that all images,
irrespectible how wide they are in reality, get
reduced/enlarged to fit the 297px width. This makes the syntax
diagrams look irregularily sized and ugly. (In the Publican
case it is even worse as there the object-element is used which
will clip the image.)
Consulting [1] one can see that 297px width corresponds to
159.28 mm = 15.93 cm = 6.22 in.
Looking at all the svg bounding boxes in the rxmath book, the
widest one is "funcs_rxcalcpower.svg" with a width of 634 px =
167.75 mm = 16.78 cm = 6.55 in. If rendering for paper the
printable width (A4) is wide enough to host the syntax diagram
without any distortion or clipping.
Therefore I would suggest to remove the width attribute from
the img element (and use the img element [2] over the object
element [3]).
Finally, both, the Publican and Gil's HTML renderings show that
the svg images display and scale in the highest resolution.
@P.O.: there would be� no need anymore to recreate the HTML
renderings for the rexxpg book.
So, Gil, thumbs up!� +1
Great job!
