Sinder" Cc: emacs-orgmode@gnu.org Hi Daniel, thanks for your patch, and for looking into this. There is already a parameter in org-mode to change the size of the images: the variable org-format-latex-options contains several parameters for creating the LaTeX images, and one of them is `:scale' - the default is 1.0, but you can set it to 1.5 or 2.0 to increase the the size. Having said that, maybe it is a good idea to allow changing the resolution - but the main purpose of this parameter would be to improve the *quality* when printing. - Carsten On Sep 1, 2006, at 23:50, Daniel J.
