One question that I would ask is why not just generate a TIFF image of the mathematical formula and connect it to a representation of the formula that would be suitable for using the formula (e.g. in whatever format Mathematica utilizes). That would simplify the presentation and actualy distribute the the formula, not just some HTML+ representation (although someone could always write an HTML+ to Mathematica converter :-) dcm -------- Emanuel Knill writes: In-reply-to: Your message of "Tue, 05 Oct 1993 18:10:10 -0000." -------- Dave Raggett writes: >According to Phil, to get good results with TeX you need to fiddle with the >style settings, and the code needed to run HTML+ with TeX for embedded >formulae would be painful, particularly with the style stuff. Is this assuming that the standard TeX program/process is run to produce a math formula? Here's a question for Phil Hallam-Baker: Do you have an encapsulated way of producing images of elementary TeX math expressions that can be embedded in html files with reasonable alignment?

I like the principle of your proposal, though I must say that the sub/superscript tags look a bit clumsy. This is of course not really a problem with a good editor. It would be nice if we could add easy-to-use facilities for embedding more complicated stuff in the future (as images or other). >We definitely need to make sure that any proposal for maths is solid and >easy to implement, otherwise browser writers are going to work on other >problems first. > >Dave Raggett I am looking forward to seeing the HTML+ math proposal. Do you have a prelimiary copy which includes the math parts? Manny
