Dear Rudolf,

Please accept my thanks for your kind and prompt reply.

I still have some queries, which I provide inline as well as in the end.

Thanks; this suggestion worked --- at least the xymatrix figure came
out; however, the arrow was almost not present:

I believe this is a rendering problem. Also the mathematics symbols get
/tiny/; could rendering of mathematics made bigger, a little bolder, and
xymatrix diagram arrows made visible?

Thanks, I am on 28.2, the latest on Linux Mint archive; I think I shall
have to download and compile from gnu archives for the latest one.

This is a problem; please see also below.

I have a huge amount of macros which are constantly used, especially
because the area of my work (Category Theory) demands use of plenty of
inline diagrams as well as displayed diagrams; for inline diagrams it is
best to have macros to speed up the typing. I believe you are saying
that while these are recognised by LaTeX for PDF documents, the html
converter just neglects them.

Firstly, is it possible to convert these macros to a form which is
acceptable by hrml converter?

I believe the answer is _Yes_, since the same commands between "$", "$"
works; but can this be automated? The suggestion is: would it be
possible to write some quick code to be used by the converter before
starting the process of conversion, so that a list of macros used is
made up, each of such macros automatically converted in a form usable
for html, and then used in the conversion disregarding the actual macro
file; the converted macros could then be placed somewhere in the header
of the converted html file.

With my regards and all the very best wishes,

partha
