To understand why that shouldn't happen you actually have to understand that you are specifically doing something which is both strange and backwards. The reason that EPS, PS, and PDF files work so well with Latex and Lyx is because PDFs are vector based graphics. Converting an EPS and a PS document to PDF should have a 1:1 lossless conversion, theoretically. There is an eps2pdf command which converts EPS and SVG files to PDF. There is also a way to include a PNG file into a PDF.
Frankly, I am extremely confused by this thread. A PDF document is vector based. If you are handing them a PDF to print, they shouldn't have any issue printing a vector based document. If you are including an EPS within a PDF, the conversion happens on the backend to make the EPS into a PDF so it is very easily included within the document. PNG images are raster based and need to be converted into a vector to be included within a PDF, or at least that is what I have read. There are libraries which will do this such as graphicx. Note that the PNG is converted into a vector based system and then included within the PDF document or it is used natively somehow and then a vector image is the result (PDF). Does this make sense? Perhaps I am just missing something but printers should love vector based graphics. Mine does. ~Ben On Sun, Jun 22, 2014 at 4:37 PM, Christian W <windi...@igpm.rwth-aachen.de> wrote: > Thank you both for your comments.
