Re: [Dvipng] diving on retina displays?

[Jan-Åke Larsson]

As a side note, I have had a few questions on fuzzy imagery, but never 
got enough responses from reporters to track the issue down.

There may be several causes for this, in some cases I suspect linking to 
very very old versions of libgd, I am thinking to remove support for 
these old versions.

In your case, the problem is likely to be up-scaling after dvipng has 
rendered the image. What I was answering below is that I do not know how 
to massage org-mode into generating high-res images but display them at 
the same size as before.

The dvipng command-line switch for resolution is -D if that helps. Look 
for the call in org-mode and change the resolution. Something more will 
need to be changed to keep the size of the displayed item, this I cannot 
help you with (just now).
