Generally I include images in my latex document by the command
However, after doing
pdflatex the image quality is always very poor in the resulting pdf file. I think it is probably due to the scaling I do. I have also tried pdf, ps and eps images but they also suffer the same problems. I generally use gnuplot or matplotlib to generate the graphs.
What format should I store the images so that when I scale them to be put in the latex document, they maitain their quality? What are the macros that I should use? As of now I only use
graphicx? You should be using the latter.
graphicspackage but yes in the past I have also used the
graphicxpackage but without any change in quality
