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?

1 Answer 1


The variable org-format-latex-options (use 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 Org LaTeX.

PS: Let me know if this works for you: my current machine does not have dvipng and so I cannot test this solution myself.

    The :scale property does scale up the image, but it increases the size as well as the number of pixels. I can't find an option to adjust the density of pixels, for a crisper image. I would like to generate a larger image by increasing :scale, and then tell emacs to display that image in a smaller size--would this be possible?

  • No, there just wasn't the customization I wanted. I found that the emacs-mac port supports latex snippets in svgs driven by OSX, so I'm using that.
