From b5cf0e0b77564f34c59978b103ace38140cb5112 Mon Sep 17 00:00:00 2001 From: "Moritz Schubotz (physikerwelt)" Date: Fri, 18 May 2018 19:08:51 +0200 Subject: [PATCH] Serve png mode from mathoid * Use the exactly same routines to deliver png images that are used in mathml mode. * Change the output to use mathoids png image rather than the mathml and svg output. * Locally tested on Firefox and Chrome: Depending on the mode either the SVG or the PNG path is used.
