[XeTeX] Generating cropped PDF graphics file

[R (Chandra) Chandrasekhar]

Dear Folks,

I used to generate an EPS graphics file for a logo by typesetting the text and 
lines in LaTeX as foo.tex and compiling so

latex foo
dvips -E -ofoo.eps foo.dvi
epstopdf foo.eps

to get foo.pdf.

I am now using TTF/OTF fonts in the logo and am using xelatex instead, along 
with xcolor. I have two questions:

1. Does xdvipdfmx support colours defined in xcolor using
\definecolor[named]{mycolor}{cmyk}{c, m, y, k} where c, m, y, k are in [0, 1]?

2. To crop the generated PDF file to contain only the graphic, I am compiling 
foo.tex so:

xelatex foo
pdfcrop foo

to get the output foo-crop.pdf.

Is this the preferred way to go about it, or is there another?

Many thanks.
