I'll add my solution, even thought his thread is old. Maybe this will help someone anyway.

First, I need to generate the PDF. I use XeLaTeX for that:

xelatex test.tex

Now, ImageMagick and GraphicMagic both parse parameters from left to right, so the leftmost parameter, will be executed first. I ended up using this sequence for optimal processing:

gm convert -trim -transparent white -background transparent -density 1200x1200 -resize 25% test.pdf test.png

It gives nice graphics on transparent background, trimmed to what is actually on the page. The -density and -resize parameters, give a better granularity, and increase overall resolution.

I suggest checking if the density can be decreased for you. It'll cut down converting time.
