Change vim concealed text font size

Question

I want to increase the font size of my concealed latex symbols / titles. I haven't found a straightforward way to do this. Is there an obscure hack that would work?

It looks as though it has been done in Emacs AUCTeX: aquamacs screenshot

I'm aware that the formula in the screenshot comes from a png file, but at least it uses a bigger font for the title.

Answer 1

While Vim does not allow you to change the font size (i.e, all fonts in Vim instance must be same size) it does allow you to apply special highlighting and/or a different font. To do this you could, e.g., simply make all Conceal text bold and underlined:

:highight Conceal gui=bold,underline cterm=bold,underline

You could also change the default colors:

:highight Conceal gui=bold,underline cterm=bold,underline guifg=yellow guibg=red ctermfg=yellow ctermbg=red

You can also change the font used by Conceal text. (Technically I think it is possible to specify a (bitmap) font of larger size, but that's not advised because it will screw up screen drawing):

:highight Conceal font=Monaco gui=bold,underline cterm=bold,underline guifg=yellow guibg=red ctermfg=yellow ctermbg=red

Answer 2

As far as I know this is not possible in vim. In console vim you are limited by your terminal's capabilities and in the gui there is only one setting for the font, guifont.
