Instrument Anything in Rails 3

With Rails 3.0 released a few weeks ago I've migrated a few apps and I'm constantly finding useful new improvements. One such improvement is the ability to log anything in the same way that Rails internally logs ActiveRecord and ActionView. By default Rails 3 logs look slightly spiffier than those produced by Rails 2.3: (notice the second line has been cleaned up)

$ convert -quality 80 fig.png fig.jpg

I find a quality factor of 80 on high resolution images gives good compresssion without too much loss in quality. You can then to convert the image to eps using "convert" with the eps2 settings:

$ convert fig.jpg eps2:fig.eps

If you can use level 3 postscript, you can convert directly from png to eps:

$ convert fig.png eps3:fig.eps
