Hi - I can do the HTML section, but I might be able to offer you a better solution. I apologise for the fact that I cannot seem to find an easier way to get this info to you - other than to do this! But this is ALL I could do for the bid. However ...
My offer - I can write you quite a cutting-edge system ... it might be just what you are after. I am a Perl scripter (over 7 years exp.) with 18 years of DTP experience. I can write basic Postscript without referring to a manual (I also hand code quite complex HTML). I have spent years breaking apart QuarkXPress EPS files to see how they work - & I have this quite well figured out. I can manipulate ALL the text via scripts, including amending strings of text within the EPS file, changing text alignment, moving text with their cartesian co-ords, chaning the size of the text (both horizontal & vertical) & altering the font. I can now analyse an EPS file, find all the variable content, locate the co-ords of this content, convert this to CSS co-ords & combine with HTML & display, convert the EPS (in the background, invisibly to the user) into a JPEG & display on the users browser. The result is a pixel-perfect rendition of ANY artwork, with any number of adjustments within the file, displayed back to the user. This is big money from Quark. I have written a full artworking solution single-handedly for Renault UK. It all adds up to an incredible artworking system. This is web-based with the user having no idea they are actually creating their own artwork. Thank you for letting me bore you!
THE LATTER SECTION WOULD COST 3-4 x MY ABOVE BID
