This question already has an answer here:
I have a pdf image (density plot)
If I open it with some pdf viewer (I have tested Max OSX preview, Acrobat reader) the figure looks fine, without white lines. However, after compiling the TeX with pdf-latex, then white lines appear if I open de file with Skim or Preview programs and the white lines are there, but they do not appear when I open it with Acrobat reader.
Does anyone know how to remove the white lines in the pdf output for any pdf viewer?
Thank you very much for the help
