Graphics format conversion

by on Dec.09, 2009, under LaTeX, Linux, Software

Up until now I have been using the ‘convert‘ tool that comes with ImageMagick to switch between image formats — mainly for creating EPS files from JPG/PNG (raster format) files for use with LaTeX. Then I came across sam2p.

It is a light-weight utility that does one thing only and it does it well: convert between image formats. I’ve been using it for a while now and find that it can greatly reduce files sizes with minimal drop in quality. I’ve even used it to process existing EPS files just to get the reduction in file size. Best of all, it is multi-platform — executables are available for both Windows and Linux on the project homepage.

Goodbye convert and hello sam2p!

PSfrag for EPS Graphichs Text Manipulation

by on Jan.17, 2006, under How To ..., LaTeX, Software

There’s a nice package called psfrag that allows you to insert LaTeX constructs into EPS figures. This is specially useful with EPS files saved from MATLAB plots. The way it works is by replacing a given tag in the text of the EPS file with the LaTeX construct.

E.g. label the x-axis of of the plot as XLABEL and save the plot as an EPS file. Then, when you include that file, just put in the \psfrag{}{} tag:


The most obvious disadvantage is that it only works with EPS figures — so no PdfLaTeX. So, to compile a document to PDF, you’ll need to go the old latex -> dvi2ps -> ps2pdf way.

More details can be found on CTAN.
