Rendering compared

The same equations, rendered four ways. The first three come from this service and share a single conversion: LaTeX becomes MathML, that MathML is laid out as SVG, and the SVG is rasterised to PNG. The fourth is the original CodeCogs renderer, which runs a real LaTeX installation.

The interesting comparisons are between the columns rather than down them. MathML is laid out by the browser and reflows with the text around it; SVG and PNG are laid out here and arrive fixed. The byte counts under each are what the reader actually downloads.
