            Bug ID: 136652
           Summary: Do not write "VCLMTF" replacement image for math
                    formula
           Product: LibreOffice
           Version: 7.0.0.3 release
          Hardware: All
                OS: All
            Status: UNCONFIRMED
          Severity: enhancement
          Priority: medium
         Component: LibreOffice
          Assignee: libreoffice-bugs at lists.freedesktop.org
          Reporter: rb.henschel at t-online.de

When a document is saved, that contains a math formula object, not only the
object with MathML is written but in addition an image in format "VCLMTF".

That should not happen, because such image is useless. No other application can
read that format and LibreOffice, Apache OpenOffice or MS Office do not need
it, because they can read the original MathML.

The purpose of a second object in a <draw:frame> element is, that applications,
which are not able to read the first object (here the MathML) can show the
second object instead. For this purpose the format "VCLMTF" is totally
unsuitable. For that purpose a png-format would be best.
