NOTE: there are several threads in Stack regarding this issue but any of them solved my problem.
I am using Overleaf to compose a Latex document and convert it to PDF. The ACM journal I am trying to submit it for wants that PDF to be made without Type 3 fonts (just Postscript Type 1 or TrueType). The editor said that "one common way Type 3 fonts can end up in a document is in Figures generated within PowerPoint or in charts generated in Excel." I made some of the figures using PowerPoint and took screenshots from them on my Mac. I do not know even if those images are the source of the problem but I have a Type 3 font called BitstramVeraSans-Roman in my document. So, I would like to know if:
- Is there any way of identifying the source of that Type 3 font in Mac OS?
- How could convert that Type 3 font into a Postscript Type 1 or TrueType one?
