I wanted to insert some pdf-format images in a Word document, but they always look fuzzy when I do this.
My colleague James suggested I convert the pdf files to a lossless image format like tiff or jpeg or png.
I was able to do this on Linux, using the ImageMagick command:
% convert -density 250 figure.pdf -quality 100 figure.png
where figure.pdf was my input pdf file, and figure.png was the output png file.
Thanks to my colleague James Cotton for helpful advice!
