I had today some surprising experience in converting svg to pdf using inkscape.
I am preparing drawings for laser cutter. for laser cutting, the drawing should be passed as pdf and the line stroke should be 0.001m (1µm) or less. I can set this in inkscape easily. but when exporting, the pdf "looks" empty and cannot be printed. this is in fact not completely true. here are some observations I made : - file has normal weight (compared to the one with 1mm - see below) - nothing can be seen from acrobat reader - as I sent my file along using gmail, google apps pdf previewer displayed properly the drawing (with very fairly line)
I could fix the problem by exporting the drawing to pdf with 1mm line stroke and then use libre office pdf editing capabilities to get the line stroke back at 1µm and saving it back to pdf.
there might not be big differences in how the pdf is written by both apliccations. could there be some rounding effect (in inkscape)
at the end, this is not handy, and I am wondering why is that. any idea on this ? have I missed something in the pdf export ?
