On a high res display, these latex fragments created by
C-c C-x C-l are noticeably blurry compared to the text. I gather that they are processed with imagemagick--how can I tweak it to output higher res images?
M-x customize-variable org-format-latex-options RET to customize) is a property list with parameters controlling creation of images for LaTeX fragments. In particular, the
:scale property controls image resolution. The default is
1.0; set to
2.0 to double image resolution, etc.
To find an option like this one, try
M-x customize-group RET Org RET and look for variables and subgroups that match what you want to adjust. In this case,
org-format-latex-options is in the group
PS: Let me know if this works for you: my current machine does not have
dvipng and so I cannot test this solution myself.
