Can it be achived thru ImageMagik?

Thanks...

You don't say what output format. Note, generally for PDF you need to specify a density before reading the image and converting to some other format. Also, very important, IM will rasterize your PDF and then convert back to vector (see http://www.imagemagick.org/Usage/formats/#vector)

If you are new to IM, please see

and

For PDF specific options see.
