I also was wondering if such limitation exist with other software
such as latexml and lwarp, or do those not use DVI?I don't know for sure if they do or don't use DVI, but I don't think so. Anything that uses DVI files will have the same problem. It's inherent in the DVI file format. I don't know of any DVI-reading software that bypasses the two-byte postamble value that states the number of pages. -k
