Thanks for your excellent work. I found your lib is very helpful for my project, but I got some problems as described below:

Describe the bug

1. Equation created by Equation Editor (Microsoft Equation 3.0) in Word file (.docx) can not display when previewing in browser
2. Shape can not display when previewing in browser

It uses .WMF file format to store rendered images. Since browsers doesn't support such format (except IE), those images are not displayed.

Since .WMF file format is obsolete, there is no good JS implementation of WMF pareser/renderer and I'm not intereseted in implementation of such parser since it too much work, best workarround is to avoid of using OLE objects by using tools that works with MML specification.

P.S. looks like Microsoft Equation 3.0 is deprecated as well

Thank you for your answer, @VolodymyrBaydalka

• About WMF: I will try to convert WMF to SVG by other technique.
• About Shape Drawing (as the last picture in my document above), do you have plan to implement?

I have plans to implement rendering of complex shapes, not just images. But since this is hobby project, I don't think it will be implemented in near future.
