It seems LaTeX support in WordPress.com just went from bad to worse (I'm guessing there was a recent upgrade to the .com site that related to LaTeX?) By bad I mean the continued use in 2013 of .png files to display math equations, when browsers all contain LaTeX rendering engines, and worse, that you don't expand the sum macro correctly. The summation parameters should be above and below the sigma bars, not at their ends. I can swear that when I wrote and published a recent post containing two such equations they rendered correctly, but as of today, they don't. Please see:
Why don't you scrap that JetPack LaTeX strategy that renders .png and switch to MathJax? That one decision would greatly improve the appearance of LaTeX equations and solve a whole range of typesetting alignment and size problems. My .org sandbox in MAMP that uses MathJax, not JetPack, renders LaTeX expressions beautifully, but if your going to continue to render .png image files, then at least do it right and make them more readable. It's 2013 guys, so it's time to step up and make a better design. You can easily query the server to discover the user's browser and make a decision whether that particular browser contains a LaTeX rendering engine. Send a .png only if they don't. Most will, since most users keep their browsers fairly current. The need for .png LaTeX files is mostly history.
So, am I right, that you guys tweaked the LaTeX rendering engine in .com so that sum is now ugly and awful? I can send screen shots of both my .com and .org instances and the LaTeX code I use but that url I included contains both. When do you intend to fix this? I hear a .org thomasdocheri.com calling me.
The blog I need help with is thomasdocheri.com.
