What’s the best way to create full publication-quality (i.e. vector) figures from multiple subplots, from various sources? For example, I want to include a TIFF microscopy image and an EPS plot exported from Matlab in the same figure. A friend suggested PowerPoint, but it no longer supports EPS plots. Loading and exporting the full figures from Matlab is an option. I haven't used LaTeX – if this is suggested, what packages would be required?
My journal requires figures to be in EPS or TIFF format.
