I am just curious, why sometimes I see, when compiling with tex4ht, using SVG for math, messages that says
processing page nnnnn page is empty ------> I see so many of them. Interspersed between not empty pages. I am now compiling one large file and seeing these. But I see them on many other files, just thought to ask. I can provide more information. The strange thing, I see nothing wrong in the HTML so far, but this produces hundreds of web pages with lots of math and I could have missed something. There are no errors, compile completes OK. Can one ignore such messages? have others seen them? Why they show up? Here is example "processing page 11399 graphic size: 2570.18pt x 40.2412pt (903.315mm x 14.1432mm) output written to report-11399.svg processing page 11400 page is empty graphic size: 0pt x 0pt (0mm x 0mm) output written to report-11400.svg processing page 11401 graphic size: 348.8pt x 18.8627pt (122.589mm x 6.62948mm) output written to report-11401.svg processing page 11402 graphic size: 1436.85pt x 45.4672pt (504.995mm x 15.9799mm) output written to report-11402.svg processing page 11403 page is empty graphic size: 0pt x 0pt (0mm x 0mm) output written to report-11403.svg .... processing page 12211 page is empty graphic size: 0pt x 0pt (0mm x 0mm) output written to report-12211.svg processing page 12212 graphic size: 1461.2pt x 35.8913pt (513.555mm x 12.6144mm) output written to report-12212.svg processing page 12213 page is empty graphic size: 0pt x 0pt (0mm x 0mm) output written to report-12213.svg .... processing page 13331 page is empty graphic size: 0pt x 0pt (0mm x 0mm) output written to report-13331.svg 13331 of 13331 pages converted in 5515.39 seconds Make4ht: tex4ht -cmozhtf -utf8 "report.dvi" can be executed only 1x Make4ht: t4ht -p "report.dvi" can be executed only 1x Parse LG mv report-00002.svg re0x.svg mv report-00003.svg re1x.svg ..... " The above phase of the compile is the one that takes for ever. Sometimes 1 or 2 or more hrs on some large files, just seeing these "processing page ..." messages scrolling on the screen until tex4ht is done. So trying to see if there is something I could do to speed it up and if the empty pages thing has anything to do with it. Using latest tex4ht and texlive 2017. Thanks --Nasser
